| 7 | 77 |
| 78 Conversion from a Number to a String is by making the ASCII representation of | |
| 2581 | 79 the Number. Examples: |
| 80 Number 123 --> String "123" ~ | |
| 81 Number 0 --> String "0" ~ | |

| 1621 | 133 there is no automatic conversion of Float. You can use str2float() for String |
| 134 to Float, printf() for Float to String and float2nr() for Float to Number. | |

148 around the arguments, to invoke the function it refers to. Example: > |
| 55 | 149 |
| 150 :let Fn = function("MyFunc") | |
| 151 :echo Fn() | |
| 114 | 152 < *E704* *E705* *E707* |
| 819 | 153 A Funcref variable must start with a capital, "s:", "w:", "t:" or "b:". You |
| 5340 | 154 can use "g:" but the following name must still start with a capital. You |
| 819 | 155 cannot have both a Funcref variable and a function with the same name. |
| 85 | 156 |
| 114 | 157 A special case is defining a function and directly assigning its Funcref to a |
| 158 Dictionary entry. Example: > | |
| 159 :function dict.init() dict | |
| 160 : let self.val = 0 | |
| 161 :endfunction | |
| 162 | |
| 163 The key of the Dictionary can start with a lower case letter. The actual | |
| 164 function name is not used here. Also see |numbered-function|. | |
| 165 | |
| 166 A Funcref can also be used with the |:call| command: > | |
| 167 :call Fn() | |
| 168 :call dict.init() | |
| 85 | 169 |
| 170 The name of the referenced function can be obtained with |string()|. > | |
| 119 | 171 :let func = string(Fn) |
| 85 | 172 |
| 173 You can use |call()| to invoke a Funcref and use a list variable for the | |
| 174 arguments: > | |
| 119 | 175 :let r = call(Fn, mylist) |

229 An item can be any expression. Using a List for an item creates a |
| 842 | 230 List of Lists: > |
| 85 | 231 :let nestlist = [[11, 12], [21, 22], [31, 32]] |
| 55 | 232 |
| 233 An extra comma after the last item is ignored. | |
| 234 | |
| 85 | 235 |
| 236 List index ~ | |
| 237 *list-index* *E684* | |
| 55 | 238 An item in the List can be accessed by putting the index in square brackets |
| 85 | 239 after the List. Indexes are zero-based, thus the first item has index zero. > |
| 240 :let item = mylist[0] " get the first item: 1 | |
| 55 | 241 :let item = mylist[2] " get the third item: 3 |
| 85 | 242 |
| 87 | 243 When the resulting item is a list this can be repeated: > |
| 85 | 244 :let item = nestlist[0][1] " get the first list, second item: 12 |
| 55 | 245 < |
| 85 | 246 A negative index is counted from the end. Index -1 refers to the last item in |
| 247 the List, -2 to the last but one item, etc. > | |
| 55 | 248 :let last = mylist[-1] " get the last item: "four" |
| 249 | |
| 85 | 250 To avoid an error for an invalid index use the |get()| function. When an item |
| 87 | 251 is not available it returns zero or the default value you specify: > |
| 85 | 252 :echo get(mylist, idx) |
| 253 :echo get(mylist, idx, "NONE") | |
| 254 | |
| 255 | |
| 256 List concatenation ~ | |
| 257 | |
| 258 Two lists can be concatenated with the "+" operator: > | |
| 259 :let longlist = mylist + [5, 6] | |
| 119 | 260 :let mylist += [7, 8] |
| 85 | 261 |
| 262 To prepend or append an item turn the item into a list by putting [] around | |
| 263 it. To change a list in-place see |list-modification| below. | |

267 *sublist* |
| 55 | 268 A part of the List can be obtained by specifying the first and last index, |
| 269 separated by a colon in square brackets: > | |
| 85 | 270 :let shortlist = mylist[2:-1] " get List [3, "four"] |
| 55 | 271 |
| 272 Omitting the first index is similar to zero. Omitting the last index is | |
| 1156 | 273 similar to -1. > |
| 90 | 274 :let endlist = mylist[2:] " from item 2 to the end: [3, "four"] |
| 275 :let shortlist = mylist[2:2] " List with one item: [3] | |
| 276 :let otherlist = mylist[:] " make a copy of the List | |
| 85 | 277 |
| 842 | 278 If the first index is beyond the last item of the List or the second item is |
| 279 before the first item, the result is an empty list. There is no error | |
| 280 message. | |
| 281 | |
| 282 If the second index is equal to or greater than the length of the list the | |
| 283 length minus one is used: > | |
| 829 | 284 :let mylist = [0, 1, 2, 3] |
| 285 :echo mylist[2:8] " result: [2, 3] | |

| 304 works, as explained above. This creates a shallow copy of the list: Changing | |
| 87 | 305 a list item in the list will also change the item in the copied list: > |
| 85 | 306 :let aa = [[1, 'a'], 2, 3] |
| 307 :let bb = copy(aa) | |
| 114 | 308 :call add(aa, 4) |
| 85 | 309 :let aa[0][1] = 'aaa' |
| 310 :echo aa | |
| 114 | 311 < [[1, aaa], 2, 3, 4] > |
| 85 | 312 :echo bb |
| 114 | 313 < [[1, aaa], 2, 3] |
| 85 | 314 |
| 87 | 315 To make a completely independent list use |deepcopy()|. This also makes a |
| 114 | 316 copy of the values in the list, recursively. Up to a hundred levels deep. |
| 85 | 317 |
| 318 The operator "is" can be used to check if two variables refer to the same | |
| 114 | 319 List. "isnot" does the opposite. In contrast "==" compares if two lists have |
| 87 | 320 the same value. > |
| 321 :let alist = [1, 2, 3] | |
| 322 :let blist = [1, 2, 3] | |
| 323 :echo alist is blist | |
| 114 | 324 < 0 > |
| 87 | 325 :echo alist == blist |
| 114 | 326 < 1 |
| 85 | 327 |
| 323 | 328 Note about comparing lists: Two lists are considered equal if they have the |
| 329 same length and all items compare equal, as with using "==". There is one | |
| 388 | 330 exception: When comparing a number with a string they are considered |
| 331 different. There is no automatic type conversion, as with using "==" on | |
| 332 variables. Example: > | |
| 333 echo 4 == "4" | |
| 323 | 334 < 1 > |
| 388 | 335 echo [4] == ["4"] |
| 323 | 336 < 0 |
| 337 | |
| 388 | 338 Thus comparing Lists is more strict than comparing numbers and strings. You |
| 1621 | 339 can compare simple values this way too by putting them in a list: > |
| 388 | 340 |
| 341 :let a = 5 | |
| 342 :let b = "5" | |
| 1621 | 343 :echo a == b |
| 388 | 344 < 1 > |
| 1621 | 345 :echo [a] == [b] |
| 388 | 346 < 0 |
| 323 | 347 |
| 85 | 348 |
| 349 List unpack ~ | |
| 350 | |
| 351 To unpack the items in a list to individual variables, put the variables in | |
| 352 square brackets, like list items: > | |
| 353 :let [var1, var2] = mylist | |
| 354 | |
| 355 When the number of variables does not match the number of items in the list | |
| 356 this produces an error. To handle any extra items from the list append ";" | |
| 357 and a variable name: > | |
| 358 :let [var1, var2; rest] = mylist | |
| 359 | |
| 360 This works like: > | |
| 361 :let var1 = mylist[0] | |
| 362 :let var2 = mylist[1] | |
| 95 | 363 :let rest = mylist[2:] |
| 85 | 364 |
| 365 Except that there is no error if there are only two items. "rest" will be an | |
| 366 empty list then. | |
| 367 | |
| 368 | |
| 369 List modification ~ | |
| 370 *list-modification* | |
| 87 | 371 To change a specific item of a list use |:let| this way: > |
| 85 | 372 :let list[4] = "four" |
| 373 :let listlist[0][3] = item | |
| 374 | |
| 87 | 375 To change part of a list you can specify the first and last item to be |
| 114 | 376 modified. The value must at least have the number of items in the range: > |
| 87 | 377 :let list[3:5] = [3, 4, 5] |
| 378 | |
| 85 | 379 Adding and removing items from a list is done with functions. Here are a few |
| 380 examples: > | |
| 381 :call insert(list, 'a') " prepend item 'a' | |
| 382 :call insert(list, 'a', 3) " insert item 'a' before list[3] | |
| 383 :call add(list, "new") " append String item | |
| 114 | 384 :call add(list, [1, 2]) " append a List as one new item |
| 85 | 385 :call extend(list, [1, 2]) " extend the list with two more items |
| 386 :let i = remove(list, 3) " remove item 3 | |
| 108 | 387 :unlet list[3] " idem |
| 85 | 388 :let l = remove(list, 3, -1) " remove items 3 to last item |
| 108 | 389 :unlet list[3 : ] " idem |
| 114 | 390 :call filter(list, 'v:val !~ "x"') " remove items with an 'x' |
| 391 | |
| 392 Changing the order of items in a list: > | |
| 87 | 393 :call sort(list) " sort a list alphabetically |
| 394 :call reverse(list) " reverse the order of items | |
| 5747 | 395 :call uniq(sort(list)) " sort and remove duplicates |
| 87 | 396 |
| 85 | 397 |
| 398 For loop ~ | |
| 399 | |
| 87 | 400 The |:for| loop executes commands for each item in a list. A variable is set |
| 401 to each item in the list in sequence. Example: > | |
| 114 | 402 :for item in mylist |
| 403 : call Doit(item) | |
| 85 | 404 :endfor |
| 405 | |
| 406 This works like: > | |
| 407 :let index = 0 | |
| 408 :while index < len(mylist) | |
| 114 | 409 : let item = mylist[index] |
| 410 : :call Doit(item) | |
| 85 | 411 : let index = index + 1 |
| 412 :endwhile | |
| 413 | |
| 95 | 414 If all you want to do is modify each item in the list then the |map()| |
| 114 | 415 function will be a simpler method than a for loop. |
| 95 | 416 |

417 Just like the |:let| command, |:for| also accepts a list of variables. This |
| 85 | 418 requires the argument to be a list of lists. > |
| 419 :for [lnum, col] in [[1, 3], [2, 8], [3, 0]] | |
| 420 : call Doit(lnum, col) | |
| 421 :endfor | |
| 422 | |
| 423 This works like a |:let| command is done for each list item. Again, the types | |
| 424 must remain the same to avoid an error. | |
| 425 | |
| 114 | 426 It is also possible to put remaining items in a List variable: > |
| 85 | 427 :for [i, j; rest] in listlist |
| 428 : call Doit(i, j) | |
| 429 : if !empty(rest) | |
| 430 : echo "remainder: " . string(rest) | |
| 431 : endif | |
| 432 :endfor | |
| 433 | |
| 434 | |
| 435 List functions ~ | |
| 114 | 436 *E714* |
| 85 | 437 Functions that are useful with a List: > |
| 87 | 438 :let r = call(funcname, list) " call a function with an argument list |
| 85 | 439 :if empty(list) " check if list is empty |
| 102 | 440 :let l = len(list) " number of items in list |
| 441 :let big = max(list) " maximum value in list | |
| 442 :let small = min(list) " minimum value in list | |
| 87 | 443 :let xs = count(list, 'x') " count nr of times 'x' appears in list |
| 444 :let i = index(list, 'x') " index of first 'x' in list | |
| 85 | 445 :let lines = getline(1, 10) " get ten text lines from buffer |
| 446 :call append('$', lines) " append text lines in buffer | |
| 95 | 447 :let list = split("a b c") " create list from items in a string |
| 448 :let string = join(list, ', ') " create string from list items | |
| 102 | 449 :let s = string(list) " String representation of list |
| 450 :call map(list, '">> " . v:val') " prepend ">> " to each item | |
| 99 | 451 |
| 258 | 452 Don't forget that a combination of features can make things simple. For |
| 453 example, to add up all the numbers in a list: > | |
| 454 :exe 'let sum = ' . join(nrlist, '+') | |
| 455 | |
| 99 | 456 |
| 457 1.4 Dictionaries ~ | |
| 5814 | 458 *dict* *Dictionaries* *Dictionary* |
| 99 | 459 A Dictionary is an associative array: Each entry has a key and a value. The |
| 114 | 460 entry can be located with the key. The entries are stored without a specific |
| 461 ordering. | |
| 99 | 462 |
| 463 | |
| 464 Dictionary creation ~ | |
| 114 | 465 *E720* *E721* *E722* *E723* |
| 99 | 466 A Dictionary is created with a comma separated list of entries in curly |
| 114 | 467 braces. Each entry has a key and a value, separated by a colon. Each key can |
| 468 only appear once. Examples: > | |
| 99 | 469 :let mydict = {1: 'one', 2: 'two', 3: 'three'} |
| 470 :let emptydict = {} | |
| 114 | 471 < *E713* *E716* *E717* |
| 99 | 472 A key is always a String. You can use a Number, it will be converted to a |
| 473 String automatically. Thus the String '4' and the number 4 will find the same | |

478 A value can be any expression. Using a Dictionary for a value creates a |
| 99 | 479 nested Dictionary: > |
| 480 :let nestdict = {1: {11: 'a', 12: 'b'}, 2: {21: 'c'}} | |
| 481 | |
| 482 An extra comma after the last entry is ignored. | |
| 483 | |
| 484 | |
| 485 Accessing entries ~ | |
| 486 | |
| 487 The normal way to access an entry is by putting the key in square brackets: > | |
| 488 :let val = mydict["one"] | |
| 489 :let mydict["four"] = 4 | |
| 490 | |
| 114 | 491 You can add new entries to an existing Dictionary this way, unlike Lists. |
| 99 | 492 |
| 493 For keys that consist entirely of letters, digits and underscore the following | |
| 494 form can be used |expr-entry|: > | |
| 495 :let val = mydict.one | |
| 496 :let mydict.four = 4 | |
| 497 | |
| 498 Since an entry can be any type, also a List and a Dictionary, the indexing and | |
| 499 key lookup can be repeated: > | |
| 114 | 500 :echo dict.key[idx].key |
| 99 | 501 |

505 You may want to loop over the entries in a dictionary. For this you need to |
| 99 | 506 turn the Dictionary into a List and pass it to |:for|. |
| 507 | |
| 508 Most often you want to loop over the keys, using the |keys()| function: > | |
| 509 :for key in keys(mydict) | |
| 510 : echo key . ': ' . mydict[key] | |
| 511 :endfor | |
| 512 | |
| 513 The List of keys is unsorted. You may want to sort them first: > | |
| 514 :for key in sort(keys(mydict)) | |
| 515 | |
| 516 To loop over the values use the |values()| function: > | |
| 517 :for v in values(mydict) | |
| 518 : echo "value: " . v | |
| 519 :endfor | |
| 520 | |
| 521 If you want both the key and the value use the |items()| function. It returns | |
| 1621 | 522 a List in which each item is a List with two items, the key and the value: > |
| 1156 | 523 :for [key, value] in items(mydict) |
| 524 : echo key . ': ' . value | |
| 99 | 525 :endfor |
| 526 | |
| 527 | |
| 528 Dictionary identity ~ | |
| 161 | 529 *dict-identity* |
| 99 | 530 Just like Lists you need to use |copy()| and |deepcopy()| to make a copy of a |
| 531 Dictionary. Otherwise, assignment results in referring to the same | |
| 532 Dictionary: > | |
| 533 :let onedict = {'a': 1, 'b': 2} | |
| 534 :let adict = onedict | |
| 535 :let adict['a'] = 11 | |
| 536 :echo onedict['a'] | |
| 537 11 | |
| 538 | |
| 327 | 539 Two Dictionaries compare equal if all the key-value pairs compare equal. For |
| 540 more info see |list-identity|. | |
| 99 | 541 |
| 542 | |
| 543 Dictionary modification ~ | |
| 544 *dict-modification* | |
| 545 To change an already existing entry of a Dictionary, or to add a new entry, | |
| 546 use |:let| this way: > | |
| 547 :let dict[4] = "four" | |
| 548 :let dict['one'] = item | |
| 549 | |
| 108 | 550 Removing an entry from a Dictionary is done with |remove()| or |:unlet|. |
| 551 Three ways to remove the entry with key "aaa" from dict: > | |
| 552 :let i = remove(dict, 'aaa') | |
| 553 :unlet dict.aaa | |
| 554 :unlet dict['aaa'] | |
| 99 | 555 |
| 556 Merging a Dictionary with another is done with |extend()|: > | |
| 114 | 557 :call extend(adict, bdict) |
| 558 This extends adict with all entries from bdict. Duplicate keys cause entries | |
| 559 in adict to be overwritten. An optional third argument can change this. | |
| 119 | 560 Note that the order of entries in a Dictionary is irrelevant, thus don't |
| 561 expect ":echo adict" to show the items from bdict after the older entries in | |
| 562 adict. | |
| 99 | 563 |
| 564 Weeding out entries from a Dictionary can be done with |filter()|: > | |
| 1156 | 565 :call filter(dict, 'v:val =~ "x"') |
| 114 | 566 This removes all entries from "dict" with a value not matching 'x'. |
| 102 | 567 |

572 special way with a dictionary. Example: > |
| 102 | 573 :function Mylen() dict |
| 114 | 574 : return len(self.data) |
| 102 | 575 :endfunction |
| 114 | 576 :let mydict = {'data': [0, 1, 2, 3], 'len': function("Mylen")} |
| 577 :echo mydict.len() | |
| 102 | 578 |
| 579 This is like a method in object oriented programming. The entry in the | |
| 580 Dictionary is a |Funcref|. The local variable "self" refers to the dictionary | |
| 581 the function was invoked from. | |
| 582 | |
| 114 | 583 It is also possible to add a function without the "dict" attribute as a |
| 584 Funcref to a Dictionary, but the "self" variable is not available then. | |
| 585 | |
| 819 | 586 *numbered-function* *anonymous-function* |
| 102 | 587 To avoid the extra name for the function it can be defined and directly |
| 588 assigned to a Dictionary in this way: > | |
| 114 | 589 :let mydict = {'data': [0, 1, 2, 3]} |
| 6741 | 590 :function mydict.len() |
| 114 | 591 : return len(self.data) |
| 102 | 592 :endfunction |
| 114 | 593 :echo mydict.len() |
| 594 | |
| 595 The function will then get a number and the value of dict.len is a |Funcref| | |

596 that references this function. The function can only be used through a |

724 |TRUE|, the result is the value of the expression between the '?' and ':', |
| 7 | 725 otherwise the result is the value of the expression after the ':'. |
| 726 Example: > | |
| 727 :echo lnum == 1 ? "top" : lnum | |
| 728 | |
| 729 Since the first expression is an "expr2", it cannot contain another ?:. The | |
| 730 other two expressions can, thus allow for recursive use of ?:. | |
| 731 Example: > | |
| 732 :echo lnum == 1 ? "top" : lnum == 1000 ? "last" : lnum | |
| 733 | |
| 734 To keep this readable, using |line-continuation| is suggested: > | |
| 735 :echo lnum == 1 | |
| 736 :\ ? "top" | |
| 737 :\ : lnum == 1000 | |
| 738 :\ ? "last" | |
| 739 :\ : lnum | |
| 740 | |
| 1156 | 741 You should always put a space before the ':', otherwise it can be mistaken for |
| 742 use in a variable such as "a:1". | |

860 Inside a List or Dictionary this conversion is not used. |
| 7 | 861 |
| 862 When comparing two Strings, this is done with strcmp() or stricmp(). This | |
| 863 results in the mathematical difference (comparing byte values), not | |
| 864 necessarily the alphabetical difference in the local language. | |
| 865 | |
| 1621 | 866 When using the operators with a trailing '#', or the short version and |
| 1156 | 867 'ignorecase' is off, the comparing is done with strcmp(): case matters. |
| 7 | 868 |
| 869 When using the operators with a trailing '?', or the short version and | |
| 1156 | 870 'ignorecase' is set, the comparing is done with stricmp(): case is ignored. |
| 871 | |
| 872 'smartcase' is not used. | |
| 7 | 873 |
| 874 The "=~" and "!~" operators match the lefthand argument with the righthand | |
| 875 argument, which is used as a pattern. See |pattern| for what a pattern is. | |
| 876 This matching is always done like 'magic' was set and 'cpoptions' is empty, no | |
| 877 matter what the actual value of 'magic' or 'cpoptions' is. This makes scripts | |
| 878 portable. To avoid backslashes in the regexp pattern to be doubled, use a | |
| 879 single-quote string, see |literal-string|. | |
| 880 Since a string is considered to be a single line, a multi-line pattern | |
| 881 (containing \n, backslash-n) will not match. However, a literal NL character | |
| 882 can be matched like an ordinary character. Examples: | |
| 883 "foo\nbar" =~ "\n" evaluates to 1 | |
| 884 "foo\nbar" =~ "\\n" evaluates to 0 | |
| 885 | |
| 886 | |
| 887 expr5 and expr6 *expr5* *expr6* | |
| 888 --------------- | |
| 685 | 889 expr6 + expr6 .. Number addition or |List| concatenation *expr-+* |
| 79 | 890 expr6 - expr6 .. Number subtraction *expr--* |
| 891 expr6 . expr6 .. String concatenation *expr-.* | |
| 892 | |
| 692 | 893 For |Lists| only "+" is possible and then both expr6 must be a list. The |
| 685 | 894 result is a new list with the two lists Concatenated. |
| 79 | 895 |
| 3214 | 896 expr7 * expr7 .. Number multiplication *expr-star* |
| 897 expr7 / expr7 .. Number division *expr-/* | |
| 898 expr7 % expr7 .. Number modulo *expr-%* | |
| 7 | 899 |
| 900 For all, except ".", Strings are converted to Numbers. | |
| 3214 | 901 For bitwise operators see |and()|, |or()| and |xor()|. |
| 7 | 902 |
| 903 Note the difference between "+" and ".": | |
| 904 "123" + "456" = 579 | |
| 905 "123" . "456" = "123456" | |
| 906 | |
| 1621 | 907 Since '.' has the same precedence as '+' and '-', you need to read: > |
| 908 1 . 90 + 90.0 | |
| 909 As: > | |
| 910 (1 . 90) + 90.0 | |
| 911 That works, since the String "190" is automatically converted to the Number | |
| 912 190, which can be added to the Float 90.0. However: > | |
| 913 1 . 90 * 90.0 | |
| 914 Should be read as: > | |
| 915 1 . (90 * 90.0) | |
| 916 Since '.' has lower precedence than '*'. This does NOT work, since this | |
| 917 attempts to concatenate a Float and a String. | |
| 918 | |
| 919 When dividing a Number by zero the result depends on the value: | |
| 920 0 / 0 = -0x80000000 (like NaN for Float) | |
| 921 >0 / 0 = 0x7fffffff (like positive infinity) | |
| 922 <0 / 0 = -0x7fffffff (like negative infinity) | |
| 923 (before Vim 7.2 it was always 0x7fffffff) | |

| 1621 | 1057 *floating-point-format* |
| 1058 Floating point numbers can be written in two forms: | |
| 1059 | |
| 1060 [-+]{N}.{M} | |
| 6530 | 1061 [-+]{N}.{M}[eE][-+]{exp} |
| 1621 | 1062 |
| 1063 {N} and {M} are numbers. Both {N} and {M} must be present and can only | |
| 1064 contain digits. | |
| 1065 [-+] means there is an optional plus or minus sign. | |
| 1066 {exp} is the exponent, power of 10. | |

1067 Only a decimal point is accepted, not a comma. No matter what the current |
| 1621 | 1068 locale is. |
| 1069 {only when compiled with the |+float| feature} | |
| 1070 | |
| 1071 Examples: | |
| 1072 123.456 | |
| 1073 +0.0001 | |
| 1074 55.0 | |
| 1075 -0.123 | |
| 1076 1.234e03 | |
| 1077 1.0E-6 | |
| 1078 -3.1416e+88 | |
| 1079 | |
| 1080 These are INVALID: | |
| 1081 3. empty {M} | |
| 1082 1e40 missing .{M} | |
| 1083 | |
| 1698 | 1084 *float-pi* *float-e* |
| 1085 A few useful values to copy&paste: > | |
| 1086 :let pi = 3.14159265359 | |
| 1087 :let e = 2.71828182846 | |
| 1088 | |
| 1621 | 1089 Rationale: |
| 1090 Before floating point was introduced, the text "123.456" was interpreted as | |
| 1091 the two numbers "123" and "456", both converted to a string and concatenated, | |
| 1092 resulting in the string "123456". Since this was considered pointless, and we | |
| 1698 | 1093 could not find it intentionally being used in Vim scripts, this backwards |
| 1621 | 1094 incompatibility was accepted in favor of being able to use the normal notation |
| 1095 for floating point numbers. | |
| 1096 | |
| 1097 *floating-point-precision* | |
| 1098 The precision and range of floating points numbers depends on what "double" | |
| 1099 means in the library Vim was compiled with. There is no way to change this at | |
| 1100 runtime. | |
| 1101 | |
| 1102 The default for displaying a |Float| is to use 6 decimal places, like using | |
| 1103 printf("%g", f). You can select something else when using the |printf()| | |
| 1104 function. Example: > | |
| 1105 :echo printf('%.15e', atan(1)) | |
| 1106 < 7.853981633974483e-01 | |

| 7 | 1111 ------ |
| 1112 "string" string constant *expr-quote* | |
| 1113 | |
| 1114 Note that double quotes are used. | |
| 1115 | |
| 1116 A string constant accepts these special characters: | |
| 1117 \... three-digit octal number (e.g., "\316") | |
| 1118 \.. two-digit octal number (must be followed by non-digit) | |
| 1119 \. one-digit octal number (must be followed by non-digit) | |
| 1120 \x.. byte specified with two hex numbers (e.g., "\x1f") | |
| 1121 \x. byte specified with one hex number (must be followed by non-hex char) | |
| 1122 \X.. same as \x.. | |
| 1123 \X. same as \x. | |
| 1621 | 1124 \u.... character specified with up to 4 hex numbers, stored according to the |
| 7 | 1125 current value of 'encoding' (e.g., "\u02a4") |
| 6840 | 1126 \U.... same as \u but allows up to 8 hex numbers. |
| 7 | 1127 \b backspace <BS> |
| 1128 \e escape <Esc> | |
| 1129 \f formfeed <FF> | |
| 1130 \n newline <NL> | |

| 1202 *expr-env-expand* | |
| 1203 Note that there is a difference between using $VAR directly and using | |
| 1204 expand("$VAR"). Using it directly will only expand environment variables that | |
| 1205 are known inside the current Vim session. Using expand() will first try using | |
| 1206 the environment variables known inside the current Vim session. If that | |
| 1207 fails, a shell will be used to expand the variable. This can be slow, but it | |
| 1208 does expand all variables that the shell knows about. Example: > | |
| 6180 | 1209 :echo $shell |
| 1210 :echo expand("$shell") | |
| 1211 The first one probably doesn't echo anything, the second echoes the $shell | |

| 7 | 1284 ============================================================================== |
| 2596 | 1285 3. Internal variable *internal-variables* *E461* |
| 1286 | |
| 7 | 1287 An internal variable name can be made up of letters, digits and '_'. But it |
| 1288 cannot start with a digit. It's also possible to use curly braces, see | |
| 1289 |curly-braces-names|. | |
| 1290 | |
| 1291 An internal variable is created with the ":let" command |:let|. | |
| 87 | 1292 An internal variable is explicitly destroyed with the ":unlet" command |
| 1293 |:unlet|. | |
| 1294 Using a name that is not an internal variable or refers to a variable that has | |
| 1295 been destroyed results in an error. | |
| 7 | 1296 |
| 1297 There are several name spaces for variables. Which one is to be used is | |
| 1298 specified by what is prepended: | |
| 1299 | |
| 1300 (nothing) In a function: local to a function; otherwise: global | |
| 1301 |buffer-variable| b: Local to the current buffer. | |
| 1302 |window-variable| w: Local to the current window. | |
| 819 | 1303 |tabpage-variable| t: Local to the current tab page. |
| 7 | 1304 |global-variable| g: Global. |
| 1305 |local-variable| l: Local to a function. | |
| 1306 |script-variable| s: Local to a |:source|'ed Vim script. | |
| 1307 |function-argument| a: Function argument (only inside a function). | |
| 5815 | 1308 |vim-variable| v: Global, predefined by Vim. |
| 7 | 1309 |
| 685 | 1310 The scope name by itself can be used as a |Dictionary|. For example, to |
| 1311 delete all script-local variables: > | |
| 133 | 1312 :for k in keys(s:) |
| 1313 : unlet s:[k] | |
| 1314 :endfor | |
| 1315 < | |
| 4358 | 1316 *buffer-variable* *b:var* *b:* |
| 7 | 1317 A variable name that is preceded with "b:" is local to the current buffer. |
| 1318 Thus you can have several "b:foo" variables, one for each buffer. | |
| 1319 This kind of variable is deleted when the buffer is wiped out or deleted with | |
| 1320 |:bdelete|. | |
| 1321 | |
| 1322 One local buffer variable is predefined: | |
| 4264 | 1323 *b:changedtick* *changetick* |
| 7 | 1324 b:changedtick The total number of changes to the current buffer. It is |
| 1325 incremented for each change. An undo command is also a change | |
| 1326 in this case. This can be used to perform an action only when | |
| 1327 the buffer has changed. Example: > | |
| 1328 :if my_changedtick != b:changedtick | |
| 1621 | 1329 : let my_changedtick = b:changedtick |
| 1330 : call My_Update() | |
| 7 | 1331 :endif |

| 7 | 1335 A variable name that is preceded with "w:" is local to the current window. It |
| 1336 is deleted when the window is closed. | |
| 1337 | |
| 4437 | 1338 *tabpage-variable* *t:var* *t:* |
| 819 | 1339 A variable name that is preceded with "t:" is local to the current tab page, |

1345 access a variable local to a function. But "g:" can also be used in any other |
| 7 | 1346 place if you like. |
| 1347 | |
| 4358 | 1348 *local-variable* *l:var* *l:* |
| 7 | 1349 Inside functions local variables are accessed without prepending anything. |
| 1156 | 1350 But you can also prepend "l:" if you like. However, without prepending "l:" |
| 1351 you may run into reserved variable names. For example "count". By itself it | |
| 1352 refers to "v:count". Using "l:count" you can have a local variable with the | |
| 1353 same name. | |
| 7 | 1354 |
| 1355 *script-variable* *s:var* | |
| 1356 In a Vim script variables starting with "s:" can be used. They cannot be | |
| 1357 accessed from outside of the scripts, thus are local to the script. | |
| 1358 | |
| 1359 They can be used in: | |
| 1360 - commands executed while the script is sourced | |
| 1361 - functions defined in the script | |
| 1362 - autocommands defined in the script | |
| 1363 - functions and autocommands defined in functions and autocommands which were | |
| 1364 defined in the script (recursively) | |
| 1365 - user defined commands defined in the script | |
| 1366 Thus not in: | |
| 1367 - other scripts sourced from this one | |
| 1368 - mappings | |

1369 - menus |
| 7 | 1370 - etc. |
| 1371 | |
| 1156 | 1372 Script variables can be used to avoid conflicts with global variable names. |
| 1373 Take this example: > | |
| 7 | 1374 |
| 1375 let s:counter = 0 | |
| 1376 function MyCounter() | |
| 1377 let s:counter = s:counter + 1 | |
| 1378 echo s:counter | |
| 1379 endfunction | |
| 1380 command Tick call MyCounter() | |
| 1381 | |
| 1382 You can now invoke "Tick" from any script, and the "s:counter" variable in | |
| 1383 that script will not be changed, only the "s:counter" in the script where | |
| 1384 "Tick" was defined is used. | |
| 1385 | |
| 1386 Another example that does the same: > | |
| 1387 | |
| 1388 let s:counter = 0 | |
| 1389 command Tick let s:counter = s:counter + 1 | echo s:counter | |
| 1390 | |
| 1391 When calling a function and invoking a user-defined command, the context for | |
| 9 | 1392 script variables is set to the script where the function or command was |
| 7 | 1393 defined. |
| 1394 | |
| 1395 The script variables are also available when a function is defined inside a | |
| 1396 function that is defined in a script. Example: > | |
| 1397 | |
| 1398 let s:counter = 0 | |
| 1399 function StartCounting(incr) | |
| 1400 if a:incr | |
| 1401 function MyCounter() | |
| 1402 let s:counter = s:counter + 1 | |
| 1403 endfunction | |
| 1404 else | |
| 1405 function MyCounter() | |
| 1406 let s:counter = s:counter - 1 | |
| 1407 endfunction | |
| 1408 endif | |
| 1409 endfunction | |
| 1410 | |
| 1411 This defines the MyCounter() function either for counting up or counting down | |
| 1412 when calling StartCounting(). It doesn't matter from where StartCounting() is | |
| 1413 called, the s:counter variable will be accessible in MyCounter(). | |
| 1414 | |
| 1415 When the same script is sourced again it will use the same script variables. | |
| 1416 They will remain valid as long as Vim is running. This can be used to | |
| 1417 maintain a counter: > | |
| 1418 | |
| 1419 if !exists("s:counter") | |
| 1420 let s:counter = 1 | |
| 1421 echo "script executed for the first time" | |
| 1422 else | |
| 1423 let s:counter = s:counter + 1 | |
| 1424 echo "script executed " . s:counter . " times now" | |
| 1425 endif | |
| 1426 | |
| 1427 Note that this means that filetype plugins don't get a different set of script | |
| 1428 variables for each buffer. Use local buffer variables instead |b:var|. | |
| 1429 | |
| 1430 | |
| 4358 | 1431 Predefined Vim variables: *vim-variable* *v:var* *v:* |
| 7 | 1432 |
| 189 | 1433 *v:beval_col* *beval_col-variable* |
| 1434 v:beval_col The number of the column, over which the mouse pointer is. | |
| 1435 This is the byte index in the |v:beval_lnum| line. | |
| 1436 Only valid while evaluating the 'balloonexpr' option. | |
| 1437 | |
| 1438 *v:beval_bufnr* *beval_bufnr-variable* | |
| 1439 v:beval_bufnr The number of the buffer, over which the mouse pointer is. Only | |
| 1440 valid while evaluating the 'balloonexpr' option. | |
| 1441 | |
| 1442 *v:beval_lnum* *beval_lnum-variable* | |
| 1443 v:beval_lnum The number of the line, over which the mouse pointer is. Only | |
| 1444 valid while evaluating the 'balloonexpr' option. | |
| 1445 | |
| 1446 *v:beval_text* *beval_text-variable* | |
| 374 | 1447 v:beval_text The text under or after the mouse pointer. Usually a word as |
| 1448 it is useful for debugging a C program. 'iskeyword' applies, | |
| 1449 but a dot and "->" before the position is included. When on a | |
| 1450 ']' the text before it is used, including the matching '[' and | |
| 189 | 1451 word before it. When on a Visual area within one line the |
| 1452 highlighted text is used. | |
| 1453 Only valid while evaluating the 'balloonexpr' option. | |
| 1454 | |
| 1455 *v:beval_winnr* *beval_winnr-variable* | |
| 1456 v:beval_winnr The number of the window, over which the mouse pointer is. Only | |
| 2709 | 1457 valid while evaluating the 'balloonexpr' option. The first |
| 1458 window has number zero (unlike most other places where a | |
| 1459 window gets a number). | |

| 1733 | 1734 *v:oldfiles* *oldfiles-variable* |
| 1735 v:oldfiles List of file names that is loaded from the |viminfo| file on | |
| 1736 startup. These are the files that Vim remembers marks for. | |
| 1737 The length of the List is limited by the ' argument of the | |
| 1738 'viminfo' option (default is 100). | |
| 5618 | 1739 When the |viminfo| file is not used the List is empty. |
| 1733 | 1740 Also see |:oldfiles| and |c_#<|. |
| 1741 The List can be modified, but this has no effect on what is | |
| 1742 stored in the |viminfo| file later. If you use values other | |
| 1743 than String this will cause trouble. | |

| 1823 Search direction: 1 after a forward search, 0 after a | |
| 1824 backward search. It is reset to forward when directly setting | |
| 1825 the last search pattern, see |quote/|. | |
| 1826 Note that the value is restored when returning from a | |
| 1827 function. |function-search-undo|. | |
| 1828 Read-write. | |
| 1829 | |
| 7 | 1830 *v:shell_error* *shell_error-variable* |
| 1831 v:shell_error Result of the last shell command. When non-zero, the last | |
| 1832 shell command had an error. When zero, there was no problem. | |
| 1833 This only works when the shell returns the error code to Vim. | |
| 1834 The value -1 is often used when the command could not be | |
| 1835 executed. Read-only. | |
| 1836 Example: > | |
| 1837 :!mv foo bar | |
| 1838 :if v:shell_error | |
| 1839 : echo 'could not rename "foo" to "bar"!' | |
| 1840 :endif | |
| 1841 < "shell_error" also works, for backwards compatibility. | |
| 1842 | |
| 1843 *v:statusmsg* *statusmsg-variable* | |
| 1844 v:statusmsg Last given status message. It's allowed to set this variable. | |
| 1845 | |
| 579 | 1846 *v:swapname* *swapname-variable* |
| 1847 v:swapname Only valid when executing |SwapExists| autocommands: Name of | |
| 1848 the swap file found. Read-only. | |
| 1849 | |
| 1850 *v:swapchoice* *swapchoice-variable* | |
| 1851 v:swapchoice |SwapExists| autocommands can set this to the selected choice | |
| 1852 for handling an existing swap file: | |
| 1853 'o' Open read-only | |
| 1854 'e' Edit anyway | |
| 1855 'r' Recover | |
| 1856 'd' Delete swapfile | |
| 1857 'q' Quit | |
| 1858 'a' Abort | |

1893 termcap entry. It is set when Vim receives an escape sequence |
| 7 | 1894 that starts with ESC [ or CSI and ends in a 'c', with only |
| 1895 digits, ';' and '.' in between. | |
| 1896 When this option is set, the TermResponse autocommand event is | |
| 1897 fired, so that you can react to the response from the | |
| 1898 terminal. | |
| 1899 The response from a new xterm is: "<Esc>[ Pp ; Pv ; Pc c". Pp | |
| 1900 is the terminal type: 0 for vt100 and 1 for vt220. Pv is the | |
| 1901 patch level (since this was introduced in patch 95, it's | |
| 1902 always 95 or bigger). Pc is always zero. | |
| 1903 {only when compiled with |+termresponse| feature} | |

| 2807 byte2line({byte}) *byte2line()* | |
| 2808 Return the line number that contains the character at byte | |
| 2809 count {byte} in the current buffer. This includes the | |
| 2810 end-of-line character, depending on the 'fileformat' option | |
| 2811 for the current buffer. The first character has byte count | |
| 2812 one. | |
| 2813 Also see |line2byte()|, |go| and |:goto|. | |

| 2816 | |
| 18 | 2817 byteidx({expr}, {nr}) *byteidx()* |
| 2818 Return byte index of the {nr}'th character in the string | |
| 2819 {expr}. Use zero for the first character, it returns zero. | |
| 2820 This function is only useful when there are multibyte | |
| 2821 characters, otherwise the returned value is equal to {nr}. | |
| 5413 | 2822 Composing characters are not counted separately, their byte |
| 2823 length is added to the preceding base character. See | |
| 2824 |byteidxcomp()| below for counting composing characters | |
| 2825 separately. | |

2834 If there are less than {nr} characters -1 is returned. |

| 5413 | 2836 in bytes is returned. |
| 2837 | |
| 2838 byteidxcomp({expr}, {nr}) *byteidxcomp()* | |
| 2839 Like byteidx(), except that a composing character is counted | |
| 2840 as a separate character. Example: > | |
| 2841 let s = 'e' . nr2char(0x301) | |
| 2842 echo byteidx(s, 1) | |
| 2843 echo byteidxcomp(s, 1) | |
| 2844 echo byteidxcomp(s, 2) | |
| 2845 < The first and third echo result in 3 ('e' plus composing | |
| 2846 character is 3 bytes), the second echo results in 1 ('e' is | |
| 2847 one byte). | |
| 2848 Only works different from byteidx() when 'encoding' is set to | |
| 2849 a Unicode encoding. | |
| 18 | 2850 |
| 102 | 2851 call({func}, {arglist} [, {dict}]) *call()* *E699* |
| 685 | 2852 Call function {func} with the items in |List| {arglist} as |
| 79 | 2853 arguments. |
| 685 | 2854 {func} can either be a |Funcref| or the name of a function. |
| 79 | 2855 a:firstline and a:lastline are set to the cursor line. |
| 2856 Returns the return value of the called function. | |
| 102 | 2857 {dict} is for functions with the "dict" attribute. It will be |
| 2858 used to set the local variable "self". |Dictionary-function| | |
| 79 | 2859 |
| 1621 | 2860 ceil({expr}) *ceil()* |
| 2861 Return the smallest integral value greater than or equal to | |
| 2862 {expr} as a |Float| (round up). | |
| 2863 {expr} must evaluate to a |Float| or a |Number|. | |
| 2864 Examples: > | |
| 2865 echo ceil(1.456) | |
| 2866 < 2.0 > | |
| 2867 echo ceil(-5.456) | |
| 2868 < -5.0 > | |

3066 < |
| 11062 | 3067 changenr() *changenr()* |
| 3068 Return the number of the most recent change. This is the same | |
| 3069 number as what is displayed with |:undolist| and can be used | |
| 3070 with the |:undo| command. | |
| 3071 When a change was made it is the number of that change. After | |
| 3072 redo it is the number of the redone change. After undo it is | |
| 3073 one less than the number of the undone change. | |
| 3074 | |
| 3075 char2nr({expr}[, {utf8}]) *char2nr()* | |
| 3076 Return number value of the first char in {expr}. Examples: > | |
| 3077 char2nr(" ") returns 32 | |
| 3078 char2nr("ABC") returns 65 | |
| 3079 < When {utf8} is omitted or zero, the current 'encoding' is used. | |
| 3080 Example for "utf-8": > | |
| 3081 char2nr("á") returns 225 | |
| 3082 char2nr("á"[0]) returns 195 | |
| 3083 < With {utf8} set to 1, always treat as utf-8 characters. | |
| 3084 A combining character is a separate character. | |
| 3085 |nr2char()| does the opposite. | |
| 3086 | |
| 3087 cindent({lnum}) *cindent()* | |
| 3088 Get the amount of indent for line {lnum} according the C | |
| 3089 indenting rules, as with 'cindent'. | |
| 3090 The indent is counted in spaces, the value of 'tabstop' is | |
| 3091 relevant. {lnum} is used just like in |getline()|. | |
| 3092 When {lnum} is invalid or Vim was not compiled the |+cindent| | |
| 3093 feature, -1 is returned. | |
| 3094 See |C-indenting|. | |
| 3095 | |
| 3096 clearmatches() *clearmatches()* | |
| 3097 Clears all matches previously defined by |matchadd()| and the | |
| 3098 |:match| commands. | |
| 3099 | |
| 3100 *col()* | |
| 3101 col({expr}) The result is a Number, which is the byte index of the column | |
| 3102 position given with {expr}. The accepted positions are: | |
| 3103 . the cursor position | |
| 3104 $ the end of the cursor line (the result is the | |
| 3105 number of bytes in the cursor line plus one) | |
| 3106 'x position of mark x (if the mark is not set, 0 is | |
| 3107 returned) | |
| 3108 v In Visual mode: the start of the Visual area (the | |
| 3109 cursor is the end). When not in Visual mode | |
| 3110 returns the cursor position. Differs from |'<| in | |
| 3111 that it's updated right away. | |
| 3112 Additionally {expr} can be [lnum, col]: a |List| with the line | |
| 3113 and column number. Most useful when the column is "$", to get | |
| 3114 the last column of a specific line. When "lnum" or "col" is | |
| 3115 out of range then col() returns zero. | |
| 3116 To get the line number use |line()|. To get both use | |
| 3117 |getpos()|. | |
| 3118 For the screen column position use |virtcol()|. | |
| 3119 Note that only marks in the current file can be used. | |
| 3120 Examples: > | |
| 3121 col(".") column of cursor | |
| 3122 col("$") length of cursor line plus one | |
| 3123 col("'t") column of mark t | |
| 3124 col("'" . markname) column of mark markname | |
| 3125 < The first column is 1. 0 is returned for an error. | |
| 3126 For an uppercase mark the column may actually be in another | |
| 3127 buffer. | |
| 3128 For the cursor position, when 'virtualedit' is active, the | |
| 3129 column is one higher if the cursor is after the end of the | |
| 3130 line. This can be used to obtain the column in Insert mode: > | |
| 3131 :imap <F2> <C-O>:let save_ve = &ve<CR> | |
| 3132 \<C-O>:set ve=all<CR> | |
| 3133 \<C-O>:echo col(".") . "\n" <Bar> | |
| 3134 \let &ve = save_ve<CR> | |
| 3135 < | |
| 3136 | |
| 3137 complete({startcol}, {matches}) *complete()* *E785* | |
| 3138 Set the matches for Insert mode completion. | |
| 3139 Can only be used in Insert mode. You need to use a mapping | |
| 3140 with CTRL-R = (see |i_CTRL-R|). It does not work after CTRL-O | |
| 3141 or with an expression mapping. | |
| 3142 {startcol} is the byte offset in the line where the completed | |
| 3143 text start. The text up to the cursor is the original text | |
| 3144 that will be replaced by the matches. Use col('.') for an | |
| 3145 empty string. "col('.') - 1" will replace one character by a | |
| 3146 match. | |
| 3147 {matches} must be a |List|. Each |List| item is one match. | |
| 3148 See |complete-items| for the kind of items that are possible. | |
| 3149 Note that the after calling this function you need to avoid | |
| 3150 inserting anything that would cause completion to stop. | |
| 3151 The match can be selected with CTRL-N and CTRL-P as usual with | |
| 3152 Insert mode completion. The popup menu will appear if | |
| 3153 specified, see |ins-completion-menu|. | |
| 3154 Example: > | |
| 3155 inoremap <F5> <C-R>=ListMonths()<CR> | |
| 3156 | |
| 3157 func! ListMonths() | |
| 3158 call complete(col('.'), ['January', 'February', 'March', | |
| 3159 \ 'April', 'May', 'June', 'July', 'August', 'September', | |
| 3160 \ 'October', 'November', 'December']) | |
| 3161 return '' | |
| 3162 endfunc | |
| 3163 < This isn't very useful, but it shows how it works. Note that | |
| 3164 an empty string is returned to avoid a zero being inserted. | |
| 3165 | |
| 3166 complete_add({expr}) *complete_add()* | |
| 3167 Add {expr} to the list of matches. Only to be used by the | |
| 3168 function specified with the 'completefunc' option. | |
| 3169 Returns 0 for failure (empty string or out of memory), | |
| 3170 1 when the match was added, 2 when the match was already in | |
| 3171 the list. | |
| 3172 See |complete-functions| for an explanation of {expr}. It is | |
| 3173 the same as one item in the list that 'omnifunc' would return. | |
| 3174 | |
| 3175 complete_check() *complete_check()* | |
| 3176 Check for a key typed while looking for completion matches. | |
| 3177 This is to be used when looking for matches takes some time. | |
| 3178 Returns |TRUE| when searching for matches is to be aborted, | |
| 3179 zero otherwise. | |
| 3180 Only to be used by the function specified with the | |
| 3181 'completefunc' option. | |
| 3182 | |
| 3183 *confirm()* | |
| 3184 confirm({msg} [, {choices} [, {default} [, {type}]]]) | |
| 3185 Confirm() offers the user a dialog, from which a choice can be | |
| 3186 made. It returns the number of the choice. For the first | |
| 3187 choice this is 1. | |
| 3188 Note: confirm() is only supported when compiled with dialog | |
| 3189 support, see |+dialog_con| and |+dialog_gui|. | |
| 3190 | |
| 3191 {msg} is displayed in a |dialog| with {choices} as the | |
| 3192 alternatives. When {choices} is missing or empty, "&OK" is | |
| 3193 used (and translated). | |
| 3194 {msg} is a String, use '\n' to include a newline. Only on | |
| 3195 some systems the string is wrapped when it doesn't fit. | |
| 3196 | |
| 3197 {choices} is a String, with the individual choices separated | |
| 3198 by '\n', e.g. > | |
| 3199 confirm("Save changes?", "&Yes\n&No\n&Cancel") | |
| 3200 < The letter after the '&' is the shortcut key for that choice. | |
| 3201 Thus you can type 'c' to select "Cancel". The shortcut does | |
| 3202 not need to be the first letter: > | |
| 3203 confirm("file has been modified", "&Save\nSave &All") | |
| 3204 < For the console, the first letter of each choice is used as | |
| 3205 the default shortcut key. | |
| 3206 | |
| 3207 The optional {default} argument is the number of the choice | |
| 3208 that is made if the user hits <CR>. Use 1 to make the first | |
| 3209 choice the default one. Use 0 to not set a default. If | |
| 3210 {default} is omitted, 1 is used. | |
| 3211 | |
| 3212 The optional {type} argument gives the type of dialog. This | |
| 3213 is only used for the icon of the GTK, Mac, Motif and Win32 | |
| 3214 GUI. It can be one of these values: "Error", "Question", | |
| 3215 "Info", "Warning" or "Generic". Only the first character is | |
| 3216 relevant. When {type} is omitted, "Generic" is used. | |
| 3217 | |
| 3218 If the user aborts the dialog by pressing <Esc>, CTRL-C, | |
| 3219 or another valid interrupt key, confirm() returns 0. | |
| 3220 | |
| 3221 An example: > | |
| 3222 :let choice = confirm("What do you want?", "&Apples\n&Oranges\n&Bananas", 2) | |
| 3223 :if choice == 0 | |
| 3224 : echo "make up your mind!" | |
| 3225 :elseif choice == 3 | |
| 3226 : echo "tasteful" | |
| 3227 :else | |
| 3228 : echo "I prefer bananas myself." | |
| 3229 :endif | |
| 3230 < In a GUI dialog, buttons are used. The layout of the buttons | |
| 3231 depends on the 'v' flag in 'guioptions'. If it is included, | |
| 3232 the buttons are always put vertically. Otherwise, confirm() | |
| 3233 tries to put the buttons in one horizontal line. If they | |
| 3234 don't fit, a vertical layout is used anyway. For some systems | |
| 3235 the horizontal layout is always used. | |

| 3284 cscope_connection([{num} , {dbpath} [, {prepend}]]) | |
| 3285 Checks for the existence of a |cscope| connection. If no | |
| 3286 parameters are specified, then the function returns: | |
| 3287 0, if cscope was not available (not compiled in), or | |
| 3288 if there are no cscope connections; | |
| 3289 1, if there is at least one cscope connection. | |

3363 A |Dictionary| is copied in a similar way as a |List|. |
| 685 | 3364 When {noref} is omitted or zero a contained |List| or |
| 3365 |Dictionary| is only copied once. All references point to | |
| 3366 this single copy. With {noref} set to 1 every occurrence of a | |
| 3367 |List| or |Dictionary| results in a new copy. This also means | |
| 3368 that a cyclic reference causes deepcopy() to fail. | |

3397 did_filetype() Returns |TRUE| when autocommands are being executed and the |
| 7 | 3398 FileType event has been triggered at least once. Can be used |
| 3399 to avoid triggering the FileType event again in the scripts | |
| 3400 that detect the file type. |FileType| | |
| 11473 | 3401 Returns |FALSE| when `:setf FALLBACK` was used. |
| 7 | 3402 When editing another file, the counter is reset, thus this |
| 3403 really checks if the FileType event has been triggered for the | |
| 3404 current buffer. This allows an autocommand that starts | |
| 3405 editing another buffer to set 'filetype' and load a syntax | |
| 3406 file. | |
| 3407 | |
| 32 | 3408 diff_filler({lnum}) *diff_filler()* |
| 3409 Returns the number of filler lines above line {lnum}. | |
| 3410 These are the lines that were inserted at this point in | |
| 3411 another diff'ed window. These filler lines are shown in the | |
| 3412 display but don't exist in the buffer. | |
| 3413 {lnum} is used like with |getline()|. Thus "." is the current | |
| 3414 line, "'m" mark m, etc. | |
| 3415 Returns 0 if the current window is not in diff mode. | |
| 3416 | |
| 3417 diff_hlID({lnum}, {col}) *diff_hlID()* | |
| 3418 Returns the highlight ID for diff mode at line {lnum} column | |
| 3419 {col} (byte index). When the current line does not have a | |
| 3420 diff change zero is returned. | |
| 3421 {lnum} is used like with |getline()|. Thus "." is the current | |
| 3422 line, "'m" mark m, etc. | |
| 3423 {col} is 1 for the leftmost column, {lnum} is 1 for the first | |
| 3424 line. | |
| 3425 The highlight ID can be used with |synIDattr()| to obtain | |
| 3426 syntax information about the highlighting. | |
| 3427 | |
| 85 | 3428 empty({expr}) *empty()* |
| 3429 Return the Number 1 if {expr} is empty, zero otherwise. | |

3627 If the expansion fails, the result is an empty string. A name |
| 4869 | 3628 for a non-existing file is not included, unless {expr} does |
| 3629 not start with '%', '#' or '<', see below. | |
| 7 | 3630 |
| 3631 When {expr} starts with '%', '#' or '<', the expansion is done | |
| 3632 like for the |cmdline-special| variables with their associated | |
| 3633 modifiers. Here is a short overview: | |
| 3634 | |
| 3635 % current file name | |
| 3636 # alternate file name | |
| 3637 #n alternate file name n | |
| 3638 <cfile> file name under the cursor | |
| 3639 <afile> autocmd file name | |
| 3640 <abuf> autocmd buffer number (as a String!) | |
| 3641 <amatch> autocmd matched name | |
| 5734 | 3642 <sfile> sourced script file or function name |
| 2662 | 3643 <slnum> sourced script file line number |
| 7 | 3644 <cword> word under the cursor |
| 3645 <cWORD> WORD under the cursor | |
| 3646 <client> the {clientid} of the last received | |
| 3647 message |server2client()| | |
| 3648 Modifiers: | |
| 3649 :p expand to full path | |
| 3650 :h head (last path component removed) | |
| 3651 :t tail (last path component only) | |
| 3652 :r root (one extension removed) | |
| 3653 :e extension only | |
| 3654 | |
| 3655 Example: > | |
| 3656 :let &tags = expand("%:p:h") . "/tags" | |
| 3657 < Note that when expanding a string that starts with '%', '#' or | |
| 3658 '<', any following text is ignored. This does NOT work: > | |
| 3659 :let doesntwork = expand("%:h.bak") | |
| 3660 < Use this: > | |
| 3661 :let doeswork = expand("%:h") . ".bak" | |
| 3662 < Also note that expanding "<cfile>" and others only returns the | |
| 3663 referenced file name without further expansion. If "<cfile>" | |
| 3664 is "~/.cshrc", you need to do another expand() to have the | |
| 3665 "~/" expanded into the path of the home directory: > | |
| 3666 :echo expand(expand("<cfile>")) | |
| 3667 < | |
| 3668 There cannot be white space between the variables and the | |
| 3669 following modifier. The |fnamemodify()| function can be used | |
| 3670 to modify normal file names. | |
| 3671 | |
| 3672 When using '%' or '#', and the current or alternate file name | |
| 3673 is not defined, an empty string is used. Using "%:p" in a | |
| 3674 buffer with no name, results in the current directory, with a | |
| 3675 '/' added. | |
| 3676 | |
| 3677 When {expr} does not start with '%', '#' or '<', it is | |
| 3678 expanded like a file name is expanded on the command line. | |
| 3679 'suffixes' and 'wildignore' are used, unless the optional | |

3680 {nosuf} argument is given and it is |TRUE|. |
| 3398 | 3681 Names for non-existing files are included. The "**" item can |
| 3682 be used to search in a directory tree. For example, to find | |
| 3683 all "README" files in the current directory and below: > | |
| 444 | 3684 :echo expand("**/README") |
| 3685 < | |
| 7 | 3686 Expand() can also be used to expand variables and environment |
| 3687 variables that are only known in a shell. But this can be | |
| 6180 | 3688 slow, because a shell may be used to do the expansion. See |
| 3689 |expr-env-expand|. | |
| 7 | 3690 The expanded variable is still handled like a list of file |

3691 names. When an environment variable cannot be expanded, it is |
| 7 | 3692 left unchanged. Thus ":echo expand('$FOOBAR')" results in |
| 3693 "$FOOBAR". | |

| 102 | 3703 If {expr3} is given insert the items of {expr2} before item |
| 3704 {expr3} in {expr1}. When {expr3} is zero insert before the | |
| 3705 first item. When {expr3} is equal to len({expr1}) then | |
| 3706 {expr2} is appended. | |

3714 Use |add()| to concatenate one item to a list. To concatenate |
| 82 | 3715 two lists into a new list use the + operator: > |
| 79 | 3716 :let newlist = [1, 2, 3] + [4, 5] |
| 102 | 3717 < |
| 692 | 3718 If they are |Dictionaries|: |
| 102 | 3719 Add all entries from {expr2} to {expr1}. |
| 3720 If a key exists in both {expr1} and {expr2} then {expr3} is | |
| 3721 used to decide what to do: | |
| 3722 {expr3} = "keep": keep the value of {expr1} | |
| 3723 {expr3} = "force": use the value of {expr2} | |
| 856 | 3724 {expr3} = "error": give an error message *E737* |
| 102 | 3725 When {expr3} is omitted then "force" is assumed. |
| 3726 | |
| 3727 {expr1} is changed when {expr2} is not empty. If necessary | |
| 3728 make a copy of {expr1} first. | |
| 3729 {expr2} remains unchanged. | |
| 6823 | 3730 When {expr1} is locked and {expr2} is not empty the operation |
| 3731 fails. | |
| 102 | 3732 Returns {expr1}. |
| 3733 | |
| 79 | 3734 |
| 842 | 3735 feedkeys({string} [, {mode}]) *feedkeys()* |
| 3736 Characters in {string} are queued for processing as if they | |
| 6549 | 3737 come from a mapping or were typed by the user. |
| 3738 By default the string is added to the end of the typeahead | |
| 3739 buffer, thus if a mapping is still being executed the | |
| 3740 characters come after them. Use the 'i' flag to insert before | |
| 3741 other characters, they will be executed next, before any | |
| 3742 characters from a mapping. | |
| 842 | 3743 The function does not wait for processing of keys contained in |
| 3744 {string}. | |
| 3745 To include special keys into {string}, use double-quotes | |
| 3746 and "\..." notation |expr-quote|. For example, | |
| 1215 | 3747 feedkeys("\<CR>") simulates pressing of the <Enter> key. But |
| 842 | 3748 feedkeys('\<CR>') pushes 5 characters. |
| 3749 If {mode} is absent, keys are remapped. | |
| 3750 {mode} is a String, which can contain these character flags: | |
| 843 | 3751 'm' Remap keys. This is default. |
| 3752 'n' Do not remap keys. | |
| 3753 't' Handle keys as if typed; otherwise they are handled as | |
| 3754 if coming from a mapping. This matters for undo, | |
| 3755 opening folds, etc. | |
| 6549 | 3756 'i' Insert the string instead of appending (see above). |

| 3838 upwards recursive directory searches. See |file-searching| | |
| 3839 for the syntax of {path}. | |
| 3840 Returns the path of the first found match. When the found | |
| 3841 directory is below the current directory a relative path is | |
| 3842 returned. Otherwise a full path is returned. | |
| 19 | 3843 If {path} is omitted or empty then 'path' is used. |
| 3844 If the optional {count} is given, find {count}'s occurrence of | |
| 794 | 3845 {name} in {path} instead of the first one. |
| 809 | 3846 When {count} is negative return all the matches in a |List|. |

3913 Escape {string} for use as file name command argument. All |
| 1586 | 3914 characters that have a special meaning, such as '%' and '|' |
| 3915 are escaped with a backslash. | |
| 1621 | 3916 For most systems the characters escaped are |
| 3917 " \t\n*?[{`$\\%#'\"|!<". For systems where a backslash | |
| 3918 appears in a filename, it depends on the value of 'isfname'. | |
| 1700 | 3919 A leading '+' and '>' is also escaped (special after |:edit| |
| 3920 and |:write|). And a "-" by itself (special after |:cd|). | |
| 1586 | 3921 Example: > |
| 1700 | 3922 :let fname = '+some str%nge|name' |
| 1586 | 3923 :exe "edit " . fnameescape(fname) |

| 3941 If the line {lnum} is not in a closed fold, -1 is returned. | |

| 3944 The result is a Number. If the line {lnum} is in a closed | |

| 7 | 3951 returned. If there is no fold at line {lnum}, zero is |
| 3952 returned. It doesn't matter if the folds are open or closed. | |
| 3953 When used while updating folds (from 'foldexpr') -1 is | |
| 3954 returned for lines where folds are still to be updated and the | |
| 3955 foldlevel is unknown. As a special case the level of the | |

| 435 | 4163 *getbufline()* |
| 4164 getbufline({expr}, {lnum} [, {end}]) | |
| 685 | 4165 Return a |List| with the lines starting from {lnum} to {end} |
| 4166 (inclusive) in the buffer {expr}. If {end} is omitted, a | |
| 4167 |List| with only the line {lnum} is returned. | |
| 435 | 4168 |
| 4169 For the use of {expr}, see |bufname()| above. | |
| 4170 | |
| 448 | 4171 For {lnum} and {end} "$" can be used for the last line of the |
| 4172 buffer. Otherwise a number must be used. | |
| 435 | 4173 |
| 4174 When {lnum} is smaller than 1 or bigger than the number of | |
| 685 | 4175 lines in the buffer, an empty |List| is returned. |
| 435 | 4176 |
| 4177 When {end} is greater than the number of lines in the buffer, | |
| 4178 it is treated as {end} is set to the number of lines in the | |
| 685 | 4179 buffer. When {end} is before {lnum} an empty |List| is |
| 435 | 4180 returned. |
| 4181 | |
| 448 | 4182 This function works only for loaded buffers. For unloaded and |
| 685 | 4183 non-existing buffers, an empty |List| is returned. |
| 435 | 4184 |
| 4185 Example: > | |
| 4186 :let lines = getbufline(bufnr("myfile"), 1, "$") | |
| 82 | 4187 |
| 4157 | 4188 getbufvar({expr}, {varname} [, {def}]) *getbufvar()* |
| 82 | 4189 The result is the value of option or local buffer variable |
| 4190 {varname} in buffer {expr}. Note that the name without "b:" | |
| 4191 must be used. | |
| 1668 | 4192 When {varname} is empty returns a dictionary with all the |
| 4193 buffer-local variables. | |

| 216 | 4198 This also works for a global or buffer-local option, but it |

| 4157 | 4202 When the buffer or variable doesn't exist {def} or an empty |

| 7 | 4251 There is no prompt, you will somehow have to make clear to the |
| 4252 user that a character has to be typed. | |
| 4253 There is no mapping for the character. | |
| 4254 Key codes are replaced, thus when the user presses the <Del> | |
| 4255 key you get the code for the <Del> key, not the raw character | |
| 4256 sequence. Examples: > | |
| 4257 getchar() == "\<Del>" | |
| 4258 getchar() == "\<S-Left>" | |
| 4259 < This example redefines "f" to ignore case: > | |
| 4260 :nmap f :call FindChar()<CR> | |

| 4262 : let c = nr2char(getchar()) | |
| 4263 : while col('.') < col('$') - 1 | |
| 4264 : normal l | |
| 4265 : if getline('.')[col('.') - 1] ==? c | |

| 6647 | 4271 You may also receive synthetic characters, such as |
| 6421 | 4272 |<CursorHold>|. Often you will want to ignore this and get |
| 4273 another character: > | |
| 4274 :function GetKey() | |
| 4275 : let c = getchar() | |
| 4276 : while c == "\<CursorHold>" | |
| 4277 : let c = getchar() | |

| 4279 : return c | |

| 4282 getcharmod() *getcharmod()* | |
| 4283 The result is a Number which is the state of the modifiers for | |
| 4284 the last obtained character with getchar() or in another way. | |
| 4285 These values are added together: | |
| 4286 2 shift | |

| 4430 getfsize({fname}) *getfsize()* | |
| 4431 The result is a Number, which is the size in bytes of the | |
| 4432 given file {fname}. | |
| 4433 If {fname} is a directory, 0 is returned. | |
| 4434 If the file {fname} can't be found, -1 is returned. | |
| 1293 | 4435 If the size of {fname} is too big to fit in a Number then -2 |
| 4436 is returned. | |

| 4439 Without an argument returns the name of the normal font being | |

| 4441 |hl-Normal|. | |
| 4442 With an argument a check is done whether {name} is a valid | |

| 4444 Otherwise the actual font name is returned, or {name} if the | |
| 4445 GUI does not support obtaining the real name. | |
| 824 | 4446 Only works when the GUI is running, thus not in your vimrc or |

| 37 | 4451 |
| 20 | 4452 getfperm({fname}) *getfperm()* |
| 4453 The result is a String, which is the read, write, and execute | |
| 4454 permissions of the given file {fname}. | |
| 4455 If {fname} does not exist or its directory cannot be read, an | |
| 4456 empty string is returned. | |
| 4457 The result is of the form "rwxrwxrwx", where each group of | |
| 4458 "rwx" flags represent, in turn, the permissions of the owner | |
| 4459 of the file, the group the file belongs to, and other users. | |
| 4460 If a user does not have a given permission the flag for this | |
| 3750 | 4461 is replaced with the string "-". Examples: > |
| 20 | 4462 :echo getfperm("/etc/passwd") |
| 3750 | 4463 :echo getfperm(expand("~/.vimrc")) |
| 20 | 4464 < This will hopefully (from a security point of view) display |

| 7 | 4469 getftime({fname}) *getftime()* |
| 4470 The result is a Number, which is the last modification time of | |
| 4471 the given file {fname}. The value is measured as seconds | |
| 4472 since 1st Jan 1970, and may be passed to strftime(). See also | |
| 4473 |localtime()| and |strftime()|. | |
| 4474 If the file {fname} can't be found -1 is returned. | |
| 4475 | |
| 20 | 4476 getftype({fname}) *getftype()* |
| 4477 The result is a String, which is a description of the kind of | |
| 4478 file of the given file {fname}. | |
| 4479 If {fname} does not exist an empty string is returned. | |
| 4480 Here is a table over different kinds of files and their | |

| 20 | 4496 |
| 7 | 4497 *getline()* |
| 82 | 4498 getline({lnum} [, {end}]) |
| 4499 Without {end} the result is a String, which is line {lnum} | |
| 4500 from the current buffer. Example: > | |
| 7 | 4501 getline(1) |
| 4502 < When {lnum} is a String that doesn't start with a | |
| 4503 digit, line() is called to translate the String into a Number. | |
| 4504 To get the line under the cursor: > | |
| 4505 getline(".") | |
| 4506 < When {lnum} is smaller than 1 or bigger than the number of | |
| 4507 lines in the buffer, an empty string is returned. | |
| 4508 | |
| 685 | 4509 When {end} is given the result is a |List| where each item is |
| 4510 a line from the current buffer in the range {lnum} to {end}, | |
| 82 | 4511 including line {end}. |
| 4512 {end} is used in the same way as {lnum}. | |
| 4513 Non-existing lines are silently omitted. | |
| 685 | 4514 When {end} is before {lnum} an empty |List| is returned. |
| 82 | 4515 Example: > |
| 4516 :let start = line('.') | |
| 4517 :let end = search("^$") - 1 | |

| 1326 | 4535 getmatches() *getmatches()* |
| 4536 Returns a |List| with all matches previously defined by | |
| 4537 |matchadd()| and the |:match| commands. |getmatches()| is | |
| 4538 useful in combination with |setmatches()|, as |setmatches()| | |
| 4539 can restore a list of matches saved by |getmatches()|. | |

| 4543 'priority': 10, 'id': 1}, {'group': 'MyGroup2', | |

4559 exits. On MS-DOS it's always zero. |
| 5968 | 4560 |
| 4561 *getpos()* | |
| 4562 getpos({expr}) Get the position for {expr}. For possible values of {expr} | |
| 4563 see |line()|. For getting the cursor position see | |
| 4564 |getcurpos()|. | |
| 4565 The result is a |List| with four numbers: | |
| 4566 [bufnum, lnum, col, off] | |
| 4567 "bufnum" is zero, unless a mark like '0 or 'A is used, then it | |
| 4568 is the buffer number of the mark. | |
| 4569 "lnum" and "col" are the position in the buffer. The first | |
| 4570 column is 1. | |
| 4571 The "off" number is zero, unless 'virtualedit' is used. Then | |
| 4572 it is the offset in screen columns from the start of the | |
| 4573 character. E.g., a position within a <Tab> or after the last | |
| 4574 character. | |
| 4575 Note that for '< and '> Visual mode matters: when it is "V" | |
| 4576 (visual line mode) the column of '< is zero and the column of | |
| 4577 '> is a large number. | |
| 4578 This can be used to save and restore the position of a mark: > | |
| 4579 let save_a_mark = getpos("'a") | |
| 4580 ... | |
| 6421 | 4581 call setpos("'a", save_a_mark) |

| 4814 the results. Example: > | |

| 4817 {path} is a comma-separated list of directory names. Each | |
| 7 | 4818 directory name is prepended to {expr} and expanded like with |
| 1754 | 4819 |glob()|. A path separator is inserted when needed. |
| 7 | 4820 To add a comma inside a directory name escape it with a |
| 4821 backslash. Note that on MS-Windows a directory may have a | |
| 4822 trailing backslash, remove it if you put a comma after it. | |
| 4823 If the expansion fails for one of the directories, there is no | |
| 4824 error message. | |

4905 empty the current or last used history |
| 3682 | 4906 The {history} string does not need to be the whole name, one |
| 4907 character is sufficient. | |
| 7 | 4908 If {item} does already exist in the history, it will be |
| 4909 shifted to become the newest entry. | |
| 4910 The result is a Number: 1 if the operation was successful, | |
| 4911 otherwise 0 is returned. | |
| 4912 | |
| 4913 Example: > | |
| 4914 :call histadd("input", strftime("%Y %b %d")) | |
| 4915 :let date=input("Enter date: ") | |

| 236 | 4919 Clear {history}, i.e. delete all its entries. See |hist-names| |
| 7 | 4920 for the possible values of {history}. |
| 4921 | |
| 1668 | 4922 If the parameter {item} evaluates to a String, it is used as a |
| 4923 regular expression. All entries matching that expression will | |
| 4924 be removed from the history (if there are any). | |
| 7 | 4925 Upper/lowercase must match, unless "\c" is used |/\c|. |
| 1668 | 4926 If {item} evaluates to a Number, it will be interpreted as |
| 4927 an index, see |:history-indexing|. The respective entry will | |
| 4928 be removed if it exists. | |
| 7 | 4929 |
| 4930 The result is a Number: 1 for a successful operation, | |
| 4931 otherwise 0 is returned. | |
| 4932 | |
| 4933 Examples: | |
| 4934 Clear expression register history: > | |
| 4935 :call histdel("expr") | |
| 4936 < | |
| 4937 Remove all entries starting with "*" from the search history: > | |
| 4938 :call histdel("/", '^\*') | |
| 4939 < | |

| 4941 :call histdel("search", histnr("search")) | |
| 4942 :call histdel("search", -1) | |
| 4943 :call histdel("search", '^'.histget("search", -1).'$') | |
| 4944 < | |
| 4945 To delete the last search pattern and use the last-but-one for | |
| 4946 the "n" command and 'hlsearch': > | |
| 4947 :call histdel("search", -1) | |
| 4948 :let @/ = histget("search", -1) | |
| 4949 | |
| 4950 histget({history} [, {index}]) *histget()* | |
| 4951 The result is a String, the entry with Number {index} from | |
| 4952 {history}. See |hist-names| for the possible values of | |
| 4953 {history}, and |:history-indexing| for {index}. If there is | |
| 4954 no such entry, an empty String is returned. When {index} is | |
| 4955 omitted, the most recent item from the history is used. | |
| 4956 | |
| 4957 Examples: | |
| 4958 Redo the second last search from history. > | |
| 4959 :execute '/' . histget("search", -2) | |
| 4960 | |
| 4961 < Define an Ex command ":H {num}" that supports re-execution of | |
| 4962 the {num}th entry from the output of |:history|. > | |
| 4963 :command -nargs=1 H execute histget("cmd", 0+<args>) | |
| 4964 < | |
| 4965 histnr({history}) *histnr()* | |
| 4966 The result is the Number of the current entry in {history}. | |
| 4967 See |hist-names| for the possible values of {history}. | |
| 4968 If an error occurred, -1 is returned. | |
| 4969 | |

| 4971 :let inp_index = histnr("expr") | |
| 4972 < | |
| 4973 hlexists({name}) *hlexists()* | |
| 4974 The result is a Number, which is non-zero if a highlight group | |
| 4975 called {name} exists. This is when the group has been | |
| 4976 defined in some way. Not necessarily when highlighting has | |
| 4977 been defined for it, it may also have been used for a syntax | |
| 4978 item. | |
| 4979 *highlight_exists()* | |
| 4980 Obsolete name: highlight_exists(). | |
| 4981 | |
| 4982 *hlID()* | |
| 4983 hlID({name}) The result is a Number, which is the ID of the highlight group | |
| 4984 with name {name}. When the highlight group doesn't exist, | |
| 4985 zero is returned. | |
| 4986 This can be used to retrieve information about the highlight | |

| 5069 NOTE: This function must not be used in a startup file, for | |
| 5070 the versions that only run in GUI mode (e.g., the Win32 GUI). | |
| 7 | 5071 Note: When input() is called from within a mapping it will |
| 5072 consume remaining characters from that mapping, because a | |
| 5073 mapping is handled like the characters were typed. | |
| 5074 Use |inputsave()| before input() and |inputrestore()| | |
| 5075 after input() to avoid that. Another solution is to avoid | |
| 5076 that further characters follow in the mapping, e.g., by using | |
| 5077 |:execute| or |:normal|. | |
| 5078 | |
| 531 | 5079 Example with a mapping: > |
| 7 | 5080 :nmap \x :call GetFoo()<CR>:exe "/" . Foo<CR> |
| 5081 :function GetFoo() | |
| 5082 : call inputsave() | |

5118 Restore typeahead that was saved with a previous |inputsave()|. |
| 7 | 5119 Should be called the same number of times inputsave() is |
| 5120 called. Calling it more often is harmless though. | |
| 5121 Returns 1 when there is nothing to restore, 0 otherwise. | |
| 5122 | |
| 5123 inputsave() *inputsave()* | |
| 5124 Preserve typeahead (also from mappings) and clear it, so that | |
| 5125 a following prompt gets input from the user. Should be | |
| 5126 followed by a matching inputrestore() after the prompt. Can | |
| 5127 be used several times, in which case there must be just as | |

| 5131 inputsecret({prompt} [, {text}]) *inputsecret()* | |
| 5132 This function acts much like the |input()| function with but | |
| 5133 two exceptions: | |
| 5134 a) the user's response will be displayed as a sequence of | |
| 5135 asterisks ("*") thereby keeping the entry secret, and | |
| 5136 b) the user's response will not be recorded on the input | |
| 5137 |history| stack. | |
| 5138 The result is a String, which is whatever the user actually | |
| 5139 typed on the command-line in response to the issued prompt. | |

5145 {idx}. If {idx} is zero it goes before the first item, just |
| 55 | 5146 like omitting {idx}. A negative {idx} is also possible, see |
| 5147 |list-index|. -1 inserts just before the last item. | |
| 685 | 5148 Returns the resulting |List|. Examples: > |
| 55 | 5149 :let mylist = insert([2, 3, 5], 1) |
| 5150 :call insert(mylist, 4, -1) | |
| 5151 :call insert(mylist, 6, len(mylist)) | |
| 82 | 5152 < The last example can be done simpler with |add()|. |
| 685 | 5153 Note that when {item} is a |List| it is inserted as a single |
| 692 | 5154 item. Use |extend()| to concatenate |Lists|. |
| 55 | 5155 |
| 3214 | 5156 invert({expr}) *invert()* |

| 5361 - Capitalization is ignored in literal names null, true or | |
| 5362 false, e.g. "NULL" for "null", "True" for "true". | |
| 5363 - Control characters U+0000 through U+001F which are not | |
| 5364 escaped in strings are accepted, e.g. " " (tab | |

| 5366 - Backslash in an invalid 2-character sequence escape is | |
| 5367 ignored, e.g. "\a" is decoded as "a". | |
| 5368 - A correct surrogate pair in JSON strings should normally be | |
| 5369 a 12 character sequence such as "\uD834\uDD1E", but | |
| 5370 json_decode() silently accepts truncated surrogate pairs | |
| 5371 such as "\uD834" or "\uD834\u" | |
| 5372 *E938* | |
| 5373 A duplicate key in an object, valid in rfc7159, is not | |
| 5374 accepted by json_decode() as the result must be a valid Vim | |
| 5375 type, e.g. this fails: {"a":"b", "a":"c"} | |

| 99 | 5401 keys({dict}) *keys()* |
| 685 | 5402 Return a |List| with all the keys of {dict}. The |List| is in |
| 99 | 5403 arbitrary order. |
| 5404 | |
| 85 | 5405 *len()* *E701* |
| 55 | 5406 len({expr}) The result is a Number, which is the length of the argument. |
| 5407 When {expr} is a String or a Number the length in bytes is | |
| 5408 used, as with |strlen()|. | |
| 685 | 5409 When {expr} is a |List| the number of items in the |List| is |
| 55 | 5410 returned. |
| 685 | 5411 When {expr} is a |Dictionary| the number of entries in the |
| 5412 |Dictionary| is returned. | |
| 55 | 5413 Otherwise an error is given. |
| 5414 | |
| 7 | 5415 *libcall()* *E364* *E368* |
| 5416 libcall({libname}, {funcname}, {argument}) | |
| 5417 Call function {funcname} in the run-time library {libname} | |
| 5418 with single argument {argument}. | |
| 5419 This is useful to call functions in a library that you | |
| 5420 especially made to be used with Vim. Since only one argument | |
| 5421 is possible, calling standard library functions is rather | |
| 5422 limited. | |
| 5423 The result is the String returned by the function. If the | |
| 5424 function returns NULL, this will appear as an empty string "" | |
| 5425 to Vim. | |
| 5426 If the function returns a number, use libcallnr()! | |
| 5427 If {argument} is a number, it is passed to the function as an | |
| 5428 int; if {argument} is a string, it is passed as a | |
| 5429 null-terminated string. | |
| 5430 This function will fail in |restricted-mode|. | |
| 5431 | |
| 5432 libcall() allows you to write your own 'plug-in' extensions to | |
| 5433 Vim without having to recompile the program. It is NOT a | |
| 5434 means to call system functions! If you try to do so Vim will | |
| 5435 very probably crash. | |
| 5436 | |
| 5437 For Win32, the functions you write must be placed in a DLL | |
| 5438 and use the normal C calling convention (NOT Pascal which is | |
| 5439 used in Windows System DLLs). The function must take exactly | |
| 5440 one parameter, either a character pointer or a long integer, | |
| 5441 and must return a character pointer or NULL. The character | |
| 5442 pointer returned must point to memory that will remain valid | |
| 5443 after the function has returned (e.g. in static data in the | |
| 5444 DLL). If it points to allocated memory, that memory will | |
| 5445 leak away. Using a static buffer in the function should work, | |
| 5446 it's then freed when the DLL is unloaded. | |
| 5447 | |
| 5448 WARNING: If the function returns a non-valid pointer, Vim may | |
| 1621 | 5449 crash! This also happens if the function returns a number, |
| 7 | 5450 because Vim thinks it's a pointer. |
| 5451 For Win32 systems, {libname} should be the filename of the DLL | |
| 5452 without the ".DLL" suffix. A full path is only required if | |
| 5453 the DLL is not in the usual places. | |
| 5454 For Unix: When compiling your own plugins, remember that the | |
| 5455 object code must be compiled as position-independent ('PIC'). | |

5667 When {abbr} is there and it is |TRUE| use abbreviations |
| 782 | 5668 instead of mappings. |
| 7 | 5669 A match happens with a mapping that starts with {name} and |
| 5670 with a mapping which is equal to the start of {name}. | |
| 5671 | |
| 1621 | 5672 matches mapping "a" "ab" "abc" ~ |
| 7 | 5673 mapcheck("a") yes yes yes |
| 5674 mapcheck("abc") yes yes yes | |
| 5675 mapcheck("ax") yes no no | |
| 5676 mapcheck("b") no no no | |
| 5677 | |
| 5678 The difference with maparg() is that mapcheck() finds a | |
| 5679 mapping that matches with {name}, while maparg() only finds a | |
| 5680 mapping for {name} exactly. | |
| 5681 When there is no mapping that starts with {name}, an empty | |
| 5682 String is returned. If there is one, the rhs of that mapping | |
| 5683 is returned. If there are several mappings that start with | |
| 5684 {name}, the rhs of one of them is returned. | |
| 5685 The mappings local to the current buffer are checked first, | |
| 5686 then the global mappings. | |
| 5687 This function can be used to check if a mapping can be added | |
| 5688 without being ambiguous. Example: > | |
| 5689 :if mapcheck("_vv") == "" | |
| 5690 : map _vv :set guifont=7x13<CR> | |
| 5691 :endif | |
| 5692 < This avoids adding the "_vv" mapping when there already is a | |
| 5693 mapping for "_v" or for "_vvv". | |
| 5694 | |
| 19 | 5695 match({expr}, {pat}[, {start}[, {count}]]) *match()* |
| 685 | 5696 When {expr} is a |List| then this returns the index of the |
| 5697 first item where {pat} matches. Each item is used as a | |
| 692 | 5698 String, |Lists| and |Dictionaries| are used as echoed. |

5699 Otherwise, {expr} is used as a String. The result is a |

| 5701 {pat} matches. | |
| 685 | 5702 A match at the first character or |List| item returns zero. |
| 19 | 5703 If there is no match -1 is returned. |
| 2833 | 5704 For getting submatches see |matchlist()|. |
| 19 | 5705 Example: > |

5710 Vim doesn't have a strpbrk() function. But you can do: > |
| 170 | 5711 :let sepidx = match(line, '[.,;: \t]') |
| 5712 < *strcasestr()* | |
| 5713 Vim doesn't have a strcasestr() function. But you can add | |
| 5714 "\c" to the pattern to ignore case: > | |
| 5715 :let idx = match(haystack, '\cneedle') | |
| 5716 < | |
| 95 | 5717 If {start} is given, the search starts from byte index |
| 685 | 5718 {start} in a String or item {start} in a |List|. |
| 7 | 5719 The result, however, is still the index counted from the |
| 236 | 5720 first character/item. Example: > |
| 7 | 5721 :echo match("testing", "ing", 2) |
| 5722 < result is again "4". > | |
| 5723 :echo match("testing", "ing", 4) | |
| 5724 < result is again "4". > | |
| 5725 :echo match("testing", "t", 2) | |
| 5726 < result is "3". | |
| 694 | 5727 For a String, if {start} > 0 then it is like the string starts |
| 703 | 5728 {start} bytes later, thus "^" will match at {start}. Except |
| 5729 when {count} is given, then it's like matches before the | |
| 5730 {start} byte are ignored (this is a bit complicated to keep it | |
| 5731 backwards compatible). | |
| 95 | 5732 For a String, if {start} < 0, it will be set to 0. For a list |
| 5733 the index is counted from the end. | |
| 697 | 5734 If {start} is out of range ({start} > strlen({expr}) for a |
| 5735 String or {start} > len({expr}) for a |List|) -1 is returned. | |
| 95 | 5736 |
| 694 | 5737 When {count} is given use the {count}'th match. When a match |
| 697 | 5738 is found in a String the search for the next one starts one |
| 694 | 5739 character further. Thus this example results in 1: > |
| 5740 echo match("testing", "..", 0, 2) | |
| 5741 < In a |List| the search continues in the next item. | |
| 703 | 5742 Note that when {count} is added the way {start} works changes, |
| 5743 see above. | |

5763 match. A match with a high priority will have its |
| 1326 | 5764 highlighting overrule that of a match with a lower priority. |
| 5765 A priority is specified as an integer (negative numbers are no | |
| 5766 exception). If the {priority} argument is not specified, the | |
| 5767 default priority is 10. The priority of 'hlsearch' is zero, | |
| 5768 hence all matches with a priority greater than zero will | |
| 5769 overrule it. Syntax highlighting (see 'syntax') is a separate | |
| 5770 mechanism, and regardless of the chosen priority a match will | |
| 5771 always overrule syntax highlighting. | |
| 5772 | |
| 5773 The optional {id} argument allows the request for a specific | |
| 5774 match ID. If a specified ID is already taken, an error | |
| 5775 message will appear and the match will not be added. An ID | |
| 5776 is specified as a positive integer (zero excluded). IDs 1, 2 | |
| 5777 and 3 are reserved for |:match|, |:2match| and |:3match|, | |
| 6947 | 5778 respectively. If the {id} argument is not specified or -1, |
| 1326 | 5779 |matchadd()| automatically chooses a free ID. |

5804 matchaddpos({group}, {pos}[, {priority}[, {id}[, {dict}]]]) |
| 5979 | 5805 Same as |matchadd()|, but requires a list of positions {pos} |
| 5806 instead of a pattern. This command is faster than |matchadd()| | |
| 5807 because it does not require to handle regular expressions and | |
| 5808 sets buffer line boundaries to redraw screen. It is supposed | |
| 5809 to be used when fast match additions and deletions are | |
| 5810 required, for example to highlight matching parentheses. | |
| 5811 | |
| 5812 The list {pos} can contain one of these items: | |
| 6007 | 5813 - A number. This whole line will be highlighted. The first |
| 5979 | 5814 line has number 1. |
| 5815 - A list with one number, e.g., [23]. The whole line with this | |
| 5816 number will be highlighted. | |
| 5817 - A list with two numbers, e.g., [23, 11]. The first number is | |
| 6007 | 5818 the line number, the second one is the column number (first |
| 5819 column is 1, the value must correspond to the byte index as | |
| 5820 |col()| would return). The character at this position will | |
| 5821 be highlighted. | |
| 5979 | 5822 - A list with three numbers, e.g., [23, 11, 3]. As above, but |
| 6007 | 5823 the third number gives the length of the highlight in bytes. |
| 5979 | 5824 |
| 5825 The maximum number of positions is 8. | |
| 5826 | |
| 5827 Example: > | |
| 5828 :highlight MyGroup ctermbg=green guibg=green | |
| 5829 :let m = matchaddpos("MyGroup", [[23, 24], 34]) | |
| 5830 < Deletion of the pattern: > | |
| 5831 :call matchdelete(m) | |
| 5832 | |
| 5833 < Matches added by |matchaddpos()| are returned by | |
| 5834 |getmatches()| with an entry "pos1", "pos2", etc., with the | |
| 5835 value a list like the {pos} item. | |
| 5836 These matches cannot be set via |setmatches()|, however they | |
| 5837 can still be deleted by |clearmatches()|. | |
| 5838 | |
| 819 | 5839 matcharg({nr}) *matcharg()* |
| 856 | 5840 Selects the {nr} match item, as set with a |:match|, |
| 819 | 5841 |:2match| or |:3match| command. |
| 5842 Return a |List| with two elements: | |
| 5843 The name of the highlight group used | |
| 5844 The pattern used. | |
| 5845 When {nr} is not 1, 2 or 3 returns an empty |List|. | |
| 5846 When there is no match item set returns ['', '']. | |
| 1326 | 5847 This is useful to save and restore a |:match|. |
| 5848 Highlighting matches using the |:match| commands are limited | |
| 5849 to three matches. |matchadd()| does not have this limitation. | |
| 5850 | |
| 5851 matchdelete({id}) *matchdelete()* *E802* *E803* | |
| 5852 Deletes a match with ID {id} previously defined by |matchadd()| | |
| 1621 | 5853 or one of the |:match| commands. Returns 0 if successful, |
| 1326 | 5854 otherwise -1. See example for |matchadd()|. All matches can |
| 5855 be deleted in one operation by |clearmatches()|. | |

| 6003 if getline(nextnonblank(1)) =~ "Java" | |
| 6004 < When {lnum} is invalid or there is no non-blank line at or | |

| 7 | 6009 Return a string with a single character, which has the number |
| 6010 value {expr}. Examples: > | |
| 6011 nr2char(64) returns "@" | |
| 6012 nr2char(32) returns " " | |
| 4051 | 6013 < When {utf8} is omitted or zero, the current 'encoding' is used. |
| 6014 Example for "utf-8": > | |
| 7 | 6015 nr2char(300) returns I with bow character |

| 6017 Note that a NUL character in the file is specified with | |
| 7 | 6018 nr2char(10), because NULs are represented with newline |
| 6019 characters. nr2char(0) is a real NUL and terminates the | |

| 6032 components in the path are reduced to single letters. Leading | |

6182 "ABCDEF" are used for X conversions. |
| 452 | 6183 The precision, if any, gives the minimum number of |
| 6184 digits that must appear; if the converted value | |
| 6185 requires fewer digits, it is padded on the left with | |
| 6186 zeros. | |
| 6187 In no case does a non-existent or small field width | |
| 6188 cause truncation of a numeric field; if the result of | |
| 6189 a conversion is wider than the field width, the field | |
| 6190 is expanded to contain the conversion result. | |

6220 f F The Float argument is converted into a string of the |

| 6223 zero the decimal point is omitted. When the precision | |

6227 "0.0 / 0.0" results in "nan" with %f (NAN with %F). |
| 1621 | 6228 Example: > |
| 6229 echo printf("%.2f", 12.115) | |
| 6230 < 12.12 | |
| 6231 Note that roundoff depends on the system libraries. | |
| 6232 Use |round()| when in doubt. | |
| 6233 | |
| 6234 *printf-e* *printf-E* | |
| 6235 e E The Float argument is converted into a string of the | |
| 6236 form 1.234e+03 or 1.234E+03 when using 'E'. The | |
| 6237 precision specifies the number of digits after the | |
| 6238 decimal point, like with 'f'. | |
| 6239 | |
| 6240 *printf-g* *printf-G* | |
| 6241 g G The Float argument is converted like with 'f' if the | |
| 6242 value is between 0.001 (inclusive) and 10000000.0 | |
| 6243 (exclusive). Otherwise 'e' is used for 'g' and 'E' | |
| 6244 for 'G'. When no precision is specified superfluous | |
| 6245 zeroes and '+' signs are removed, except for the zero | |
| 6246 immediately after the decimal point. Thus 10000000.0 | |
| 6247 results in 1.0e7. | |
| 6248 | |
| 6249 *printf-%* | |
| 449 | 6250 % A '%' is written. No argument is converted. The |
| 6251 complete conversion specification is "%%". | |
| 452 | 6252 |
| 1668 | 6253 When a Number argument is expected a String argument is also |
| 6254 accepted and automatically converted. | |
| 6255 When a Float or String argument is expected a Number argument | |
| 6256 is also accepted and automatically converted. | |
| 6257 Any other argument type results in an error message. | |
| 449 | 6258 |
| 459 | 6259 *E766* *E767* |
| 449 | 6260 The number of {exprN} arguments must exactly match the number |
| 6261 of "%" items. If there are not sufficient or too many | |
| 452 | 6262 arguments an error is given. Up to 18 arguments can be used. |
| 449 | 6263 |
| 6264 | |
| 667 | 6265 pumvisible() *pumvisible()* |
| 6266 Returns non-zero when the popup menu is visible, zero | |
| 6267 otherwise. See |ins-completion-menu|. | |
| 712 | 6268 This can be used to avoid some things that would remove the |
| 6269 popup menu. | |

| 692 | 6618 When the {stopline} argument is given then the search stops |

6632 {only available when compiled with the |+reltime| feature} |
| 692 | 6633 |
| 714 | 6634 *search()-sub-match* |
| 6635 With the 'p' flag the returned value is one more than the | |
| 6636 first sub-match in \(\). One if none of them matched but the | |
| 6637 whole pattern did match. | |
| 712 | 6638 To get the column number too use |searchpos()|. |
| 6639 | |
| 20 | 6640 The cursor will be positioned at the match, unless the 'n' |
| 707 | 6641 flag is used. |
| 7 | 6642 |
| 6643 Example (goes over all files in the argument list): > | |
| 6644 :let n = 1 | |
| 6645 :while n <= argc() " loop over all files in arglist | |
| 6646 : exe "argument " . n | |
| 6647 : " start at the last char in the file and wrap for the | |
| 6648 : " first search to find match at start of file | |
| 6649 : normal G$ | |
| 6650 : let flags = "w" | |
| 6651 : while search("foo", flags) > 0 | |
| 1621 | 6652 : s/foo/bar/g |
| 7 | 6653 : let flags = "W" |
| 6654 : endwhile | |
| 6655 : update " write the file if modified | |
| 6656 : let n = n + 1 | |
| 6657 :endwhile | |
| 6658 < | |
| 712 | 6659 Example for using some flags: > |
| 6660 :echo search('\<if\|\(else\)\|\(endif\)', 'ncpe') | |
| 6661 < This will search for the keywords "if", "else", and "endif" | |
| 6662 under or after the cursor. Because of the 'p' flag, it | |
| 6663 returns 1, 2, or 3 depending on which keyword is found, or 0 | |
| 6664 if the search fails. With the cursor on the first word of the | |
| 6665 line: | |
| 6666 if (foo == 0) | let foo = foo + 1 | endif ~ | |
| 6667 the function returns 1. Without the 'c' flag, the function | |
| 6668 finds the "endif" and returns 3. The same thing happens | |
| 6669 without the 'e' flag if the cursor is on the "f" of "if". | |
| 6670 The 'n' flag tells the function not to move the cursor. | |
| 6671 | |
| 504 | 6672 |
| 523 | 6673 searchdecl({name} [, {global} [, {thisblock}]]) *searchdecl()* |
| 6674 Search for the declaration of {name}. | |
| 856 | 6675 |
| 523 | 6676 With a non-zero {global} argument it works like |gD|, find |
| 6677 first match in the file. Otherwise it works like |gd|, find | |
| 6678 first match in the function. | |
| 6679 | |
| 6680 With a non-zero {thisblock} argument matches in a {} block | |
| 6681 that ends before the cursor position are ignored. Avoids | |
| 6682 finding variable declarations only valid in another scope. | |
| 6683 | |
| 504 | 6684 Moves the cursor to the found match. |
| 6685 Returns zero for success, non-zero for failure. | |
| 6686 Example: > | |
| 6687 if searchdecl('myvar') == 0 | |
| 6688 echo getline('.') | |
| 6689 endif | |
| 6690 < | |
| 7 | 6691 *searchpair()* |
| 1496 | 6692 searchpair({start}, {middle}, {end} [, {flags} [, {skip} |
| 6693 [, {stopline} [, {timeout}]]]]) | |
| 7 | 6694 Search for the match of a nested start-end pair. This can be |
| 6695 used to find the "endif" that matches an "if", while other | |
| 6696 if/endif pairs in between are ignored. | |
| 677 | 6697 The search starts at the cursor. The default is to search |
| 6698 forward, include 'b' in {flags} to search backward. | |
| 6699 If a match is found, the cursor is positioned at it and the | |
| 6700 line number is returned. If no match is found 0 or -1 is | |
| 6701 returned and the cursor doesn't move. No error message is | |
| 6702 given. | |
| 7 | 6703 |
| 6704 {start}, {middle} and {end} are patterns, see |pattern|. They | |
| 6705 must not contain \( \) pairs. Use of \%( \) is allowed. When | |
| 6706 {middle} is not empty, it is found when searching from either | |
| 6707 direction, but only when not in a nested start-end pair. A | |
| 6708 typical use is: > | |
| 6709 searchpair('\<if\>', '\<else\>', '\<endif\>') | |
| 6710 < By leaving {middle} empty the "else" is skipped. | |
| 6711 | |
| 712 | 6712 {flags} 'b', 'c', 'n', 's', 'w' and 'W' are used like with |
| 6713 |search()|. Additionally: | |
| 7 | 6714 'r' Repeat until no more matches found; will find the |
| 1621 | 6715 outer pair. Implies the 'W' flag. |
| 6716 'm' Return number of matches instead of line number with | |
| 712 | 6717 the match; will be > 1 when 'r' is used. |
| 1621 | 6718 Note: it's nearly always a good idea to use the 'W' flag, to |
| 6719 avoid wrapping around the end of the file. | |
| 7 | 6720 |
| 6721 When a match for {start}, {middle} or {end} is found, the | |
| 6722 {skip} expression is evaluated with the cursor positioned on | |
| 6723 the start of the match. It should return non-zero if this | |
| 6724 match is to be skipped. E.g., because it is inside a comment | |
| 6725 or a string. | |
| 6726 When {skip} is omitted or empty, every match is accepted. | |
| 6727 When evaluating {skip} causes an error the search is aborted | |
| 6728 and -1 returned. | |
| 6729 | |
| 1496 | 6730 For {stopline} and {timeout} see |search()|. |
| 692 | 6731 |
| 7 | 6732 The value of 'ignorecase' is used. 'magic' is ignored, the |
| 6733 patterns are used like it's on. | |
| 6734 | |
| 6735 The search starts exactly at the cursor. A match with | |
| 6736 {start}, {middle} or {end} at the next character, in the | |
| 6737 direction of searching, is the first one found. Example: > | |
| 6738 if 1 | |
| 6739 if 2 | |
| 6740 endif 2 | |
| 6741 endif 1 | |
| 6742 < When starting at the "if 2", with the cursor on the "i", and | |
| 6743 searching forwards, the "endif 2" is found. When starting on | |
| 6744 the character just before the "if 2", the "endif 1" will be | |

6745 found. That's because the "if 2" will be found first, and |
| 7 | 6746 then this is considered to be a nested if/endif from "if 2" to |
| 6747 "endif 2". | |
| 6748 When searching backwards and {end} is more than one character, | |
| 6749 it may be useful to put "\zs" at the end of the pattern, so | |
| 6750 that when the cursor is inside a match with the end it finds | |
| 6751 the matching start. | |
| 6752 | |
| 6753 Example, to find the "endif" command in a Vim script: > | |
| 6754 | |
| 6755 :echo searchpair('\<if\>', '\<el\%[seif]\>', '\<en\%[dif]\>', 'W', | |
| 6756 \ 'getline(".") =~ "^\\s*\""') | |
| 6757 | |
| 6758 < The cursor must be at or after the "if" for which a match is | |
| 6759 to be found. Note that single-quote strings are used to avoid | |
| 6760 having to double the backslashes. The skip expression only | |
| 6761 catches comments at the start of a line, not after a command. | |
| 6762 Also, a word "en" or "if" halfway a line is considered a | |
| 6763 match. | |
| 6764 Another example, to search for the matching "{" of a "}": > | |
| 6765 | |
| 6766 :echo searchpair('{', '', '}', 'bW') | |
| 6767 | |
| 6768 < This works when the cursor is at or before the "}" for which a | |
| 6769 match is to be found. To reject matches that syntax | |
| 6770 highlighting recognized as strings: > | |
| 6771 | |
| 6772 :echo searchpair('{', '', '}', 'bW', | |
| 6773 \ 'synIDattr(synID(line("."), col("."), 0), "name") =~? "string"') | |
| 6774 < | |
| 667 | 6775 *searchpairpos()* |
| 1496 | 6776 searchpairpos({start}, {middle}, {end} [, {flags} [, {skip} |
| 6777 [, {stopline} [, {timeout}]]]]) | |

7054 setreg({regname}, {value} [, {options}]) |
| 7 | 7055 Set the register {regname} to {value}. |
| 5798 | 7056 {value} may be any value returned by |getreg()|, including |
| 7057 a |List|. | |
| 7 | 7058 If {options} contains "a" or {regname} is upper case, |
| 7059 then the value is appended. | |
| 2423 | 7060 {options} can also contain a register type specification: |
| 7 | 7061 "c" or "v" |characterwise| mode |
| 7062 "l" or "V" |linewise| mode | |
| 7063 "b" or "<CTRL-V>" |blockwise-visual| mode | |
| 7064 If a number immediately follows "b" or "<CTRL-V>" then this is | |
| 7065 used as the width of the selection - if it is not specified | |
| 7066 then the width of the block is set to the number of characters | |
| 1266 | 7067 in the longest line (counting a <Tab> as 1 character). |
| 7 | 7068 |
| 7069 If {options} contains no register settings, then the default | |
| 5798 | 7070 is to use character mode unless {value} ends in a <NL> for |
| 7071 string {value} and linewise mode for list {value}. Blockwise | |
| 7072 mode is never selected automatically. | |
| 7073 Returns zero for success, non-zero for failure. | |
| 7074 | |
| 7075 *E883* | |

| 7087 without using the third argument to |getreg()| as without it | |

| 7 | 7171 simplify({filename}) *simplify()* |
| 7172 Simplify the file name as much as possible without changing | |
| 7173 the meaning. Shortcuts (on MS-Windows) or symbolic links (on | |
| 7174 Unix) are not resolved. If the first path component in | |
| 7175 {filename} designates the current directory, this will be | |
| 7176 valid for the result as well. A trailing path separator is | |
| 7177 not removed either. | |
| 7178 Example: > | |
| 7179 simplify("./dir/.././/file/") == "./file/" | |
| 7180 < Note: The combination "dir/.." is only removed if "dir" is | |
| 7181 a searchable directory or does not exist. On Unix, it is also | |
| 7182 removed when "dir" is a symbolic link within the same | |

| 375 | 7267 soundfolding. 'spell' must be set. When no sound folding is |

| 532 | 7273 spellbadword([{sentence}]) |
| 7274 Without argument: The result is the badly spelled word under | |

| 7276 bad word. When no bad word is found in the cursor line the | |
| 7277 result is an empty string and the cursor doesn't move. | |
| 7278 | |
| 7279 With argument: The result is the first word in {sentence} that | |
| 7280 is badly spelled. If there are no spelling mistakes the | |
| 7281 result is an empty string. | |
| 7282 | |
| 7283 The return value is a list with two items: | |
| 7284 - The badly spelled word or an empty string. | |
| 7285 - The type of the spelling error: | |
| 856 | 7286 "bad" spelling mistake |
| 532 | 7287 "rare" rare word |

| 7303 | |
| 537 | 7304 When the {capital} argument is given and it's non-zero only |
| 7305 suggestions with a leading capital will be given. Use this | |
| 7306 after a match with 'spellcapcheck'. | |
| 7307 | |
| 344 | 7308 {word} can be a badly spelled word followed by other text. |
| 7309 This allows for joining two words that were split. The | |
| 359 | 7310 suggestions also include the following text, thus you can |
| 7311 replace a line. | |
| 7312 | |
| 7313 {word} may also be a good word. Similar words will then be | |
| 537 | 7314 returned. {word} itself is not included in the suggestions, |
| 7315 although it may appear capitalized. | |
| 344 | 7316 |
| 7317 The spelling information for the current window is used. The | |
| 375 | 7318 'spell' option must be set and the values of 'spelllang' and |
| 7319 'spellsuggest' are used. | |
| 344 | 7320 |

| 282 | 7322 split({expr} [, {pattern} [, {keepempty}]]) *split()* |
| 685 | 7323 Make a |List| out of {expr}. When {pattern} is omitted or |
| 7324 empty each white-separated sequence of characters becomes an | |
| 7325 item. | |
| 82 | 7326 Otherwise the string is split where {pattern} matches, |
| 3920 | 7327 removing the matched characters. 'ignorecase' is not used |
| 7328 here, add \c to ignore case. |/\c| | |
| 282 | 7329 When the first or last item is empty it is omitted, unless the |
| 7330 {keepempty} argument is given and it's non-zero. | |
| 293 | 7331 Other empty items are kept when {pattern} matches at least one |
| 7332 character or when {keepempty} is non-zero. | |
| 82 | 7333 Example: > |
| 95 | 7334 :let words = split(getline('.'), '\W\+') |

7360 str2float({expr}) *str2float()* |
| 1621 | 7361 Convert String {expr} to a Float. This mostly works the same |
| 7362 as when using a floating point number in an expression, see | |
| 7363 |floating-point-format|. But it's a bit more permissive. | |
| 7364 E.g., "1e40" is accepted, while in an expression you need to | |
| 7365 write "1.0e40". | |
| 7366 Text after the number is silently ignored. | |
| 7367 The decimal point is always '.', no matter what the locale is | |
| 7368 set to. A comma ends the number: "12,345.67" is converted to | |
| 7369 12.0. You can strip out thousands separators with | |
| 7370 |substitute()|: > | |

| 7 | 7433 strftime({format} [, {time}]) *strftime()* |
| 7434 The result is a String, which is a formatted date and time, as | |
| 7435 specified by the {format} string. The given {time} is used, | |
| 7436 or the current time if no time is given. The accepted | |
| 7437 {format} depends on your system, thus this is not portable! | |
| 7438 See the manual page of the C function strftime() for the | |
| 7439 format. The maximum length of the result is 80 characters. | |
| 7440 See also |localtime()| and |getftime()|. | |
| 7441 The language can be changed with the |:language| command. | |
| 7442 Examples: > | |
| 7443 :echo strftime("%c") Sun Apr 27 11:49:23 1997 | |

| 133 | 7458 stridx({haystack}, {needle} [, {start}]) *stridx()* |
| 7459 The result is a Number, which gives the byte index in | |
| 7460 {haystack} of the first occurrence of the String {needle}. | |
| 140 | 7461 If {start} is specified, the search starts at index {start}. |
| 7462 This can be used to find a second match: > | |
| 2662 | 7463 :let colon1 = stridx(line, ":") |
| 7464 :let colon2 = stridx(line, ":", colon1 + 1) | |
| 140 | 7465 < The search is done case-sensitive. |
| 205 | 7466 For pattern searches use |match()|. |
| 133 | 7467 -1 is returned if the {needle} does not occur in {haystack}. |
| 140 | 7468 See also |strridx()|. |
| 7469 Examples: > | |

| 7472 :echo stridx("Starting point", "start") -1 | |
| 856 | 7473 < *strstr()* *strchr()* |
| 170 | 7474 stridx() works similar to the C function strstr(). When used |
| 7475 with a single character it works similar to strchr(). | |

| 7582 The result is a String, which is a copy of {expr}, in which | |

| 7586 | |
| 7587 This works like the ":substitute" command (without any flags). | |
| 7588 But the matching with {pat} is always done like the 'magic' | |
| 7589 option is set and 'cpoptions' is empty (to make scripts | |

| 32 | 7624 {lnum} and {col} in the current window. |
| 7 | 7625 The syntax ID can be used with |synIDattr()| and |
| 7626 |synIDtrans()| to obtain syntax information about text. | |

7749 When prepended by |:silent| the terminal will not be set to |
| 6183 | 7750 cooked mode. This is meant to be used for commands that do |
| 7751 not need the user to type. It avoids stray characters showing | |
| 7752 up on the screen which require |CTRL-L| to remove. > | |
| 7753 :silent let f = system('ls *.vim') | |
| 7754 < | |
| 5690 | 7755 Note: Use |shellescape()| or |::S| with |expand()| or |
| 7756 |fnamemodify()| to escape special characters in a command | |
| 7757 argument. Newlines in {expr} may cause the command to fail. | |
| 7758 The characters in 'shellquote' and 'shellxquote' may also | |
| 7759 cause trouble. | |
| 7 | 7760 This is not to be used for interactive commands. |
| 1661 | 7761 |
| 7 | 7762 The result is a String. Example: > |
| 1661 | 7763 :let files = system("ls " . shellescape(expand('%:h'))) |
| 5690 | 7764 :let files = system('ls ' . expand('%:h:S')) |
| 7 | 7765 |
| 7766 < To make the result more system-independent, the shell output | |
| 7767 is filtered to replace <CR> with <NL> for Macintosh, and | |
| 7768 <CR><NL> with <NL> for DOS-like systems. | |
| 5277 | 7769 To avoid the string being truncated at a NUL, all NUL |
| 7770 characters are replaced with SOH (0x01). | |
| 7771 | |
| 7 | 7772 The command executed is constructed using several options: |
| 7773 'shell' 'shellcmdflag' 'shellxquote' {expr} 'shellredir' {tmp} 'shellxquote' | |
| 7774 ({tmp} is an automatically generated file name). | |
| 7775 For Unix and OS/2 braces are put around {expr} to allow for | |
| 7776 concatenated commands. | |
| 7777 | |
| 794 | 7778 The command will be executed in "cooked" mode, so that a |
| 7779 CTRL-C will interrupt the command (on Unix at least). | |
| 7780 | |
| 7 | 7781 The resulting error code can be found in |v:shell_error|. |
| 7782 This function will fail in |restricted-mode|. | |
| 625 | 7783 |
| 7784 Note that any wrong value in the options mentioned above may | |
| 7785 make the function fail. It has also been reported to fail | |
| 7786 when using a security agent application. | |
| 7 | 7787 Unlike ":!cmd" there is no automatic check for changed files. |
| 7788 Use |:checktime| to force a check. | |

7804 {arg} specifies the number of the tab page to be used. When |
| 677 | 7805 omitted the current tab page is used. |
| 7806 When {arg} is invalid the number zero is returned. | |
| 7807 To get a list of all buffers in all tabs use this: > | |
| 3445 | 7808 let buflist = [] |
| 677 | 7809 for i in range(tabpagenr('$')) |
| 3445 | 7810 call extend(buflist, tabpagebuflist(i + 1)) |
| 677 | 7811 endfor |
| 7812 < Note that a buffer may appear in more than one window. | |
| 7813 | |
| 7814 | |
| 7815 tabpagenr([{arg}]) *tabpagenr()* | |
| 674 | 7816 The result is a Number, which is the number of the current |
| 7817 tab page. The first tab page has number 1. | |
| 7818 When the optional argument is "$", the number of the last tab | |
| 7819 page is returned (the tab page count). | |
| 7820 The number can be used with the |:tab| command. | |

7824 Like |winnr()| but for tab page {tabarg}. |
| 677 | 7825 {tabarg} specifies the number of tab page to be used. |
| 7826 {arg} is used like with |winnr()|: | |
| 7827 - When omitted the current window number is returned. This is | |
| 7828 the window which will be used when going to this tab page. | |
| 7829 - When "$" the number of windows is returned. | |
| 7830 - When "#" the previous window nr is returned. | |
| 7831 Useful examples: > | |
| 7832 tabpagewinnr(1) " current window of tab page 1 | |
| 7833 tabpagewinnr(4, '$') " number of windows in tab page 4 | |
| 7834 < When {tabarg} is invalid zero is returned. | |
| 7835 | |
| 805 | 7836 *tagfiles()* |
| 7837 tagfiles() Returns a |List| with the file names used to search for tags | |
| 7838 for the current buffer. This is the 'tags' option expanded. | |

| 438 | 7848 Each list item is a dictionary with at least the following |
| 7849 entries: | |
| 648 | 7850 name Name of the tag. |
| 7851 filename Name of the file where the tag is | |
| 1156 | 7852 defined. It is either relative to the |
| 7853 current directory or a full path. | |
| 205 | 7854 cmd Ex command used to locate the tag in |
| 7855 the file. | |
| 648 | 7856 kind Type of the tag. The value for this |
| 205 | 7857 entry depends on the language specific |
| 1156 | 7858 kind values. Only available when |
| 7859 using a tags file generated by | |
| 7860 Exuberant ctags or hdrtag. | |
| 648 | 7861 static A file specific tag. Refer to |
| 205 | 7862 |static-tag| for more information. |
| 1156 | 7863 More entries may be present, depending on the content of the |
| 7864 tags file: access, implementation, inherits and signature. | |
| 7865 Refer to the ctags documentation for information about these | |
| 7866 fields. For C code the fields "struct", "class" and "enum" | |
| 7867 may appear, they give the name of the entity the tag is | |
| 7868 contained in. | |
| 452 | 7869 |
| 11062 | 7870 The ex-command "cmd" can be either an ex search pattern, a |
| 216 | 7871 line number or a line number followed by a byte number. |
| 205 | 7872 |
| 7873 If there are no matching tags, then an empty list is returned. | |
| 7874 | |
| 7875 To get an exact tag match, the anchors '^' and '$' should be | |
| 4073 | 7876 used in {expr}. This also make the function work faster. |
| 7877 Refer to |tag-regexp| for more information about the tag | |
| 7878 search regular expression pattern. | |
| 205 | 7879 |
| 7880 Refer to |'tags'| for information about how the tags file is | |
| 7881 located by Vim. Refer to |tags-file-format| for the format of | |

| 7 | 8240 tolower({expr}) *tolower()* |
| 8241 The result is a copy of the String given, with all uppercase | |
| 8242 characters turned into lowercase (just like applying |gu| to | |
| 8243 the string). | |
| 8244 | |
| 8245 toupper({expr}) *toupper()* | |
| 8246 The result is a copy of the String given, with all lowercase | |
| 8247 characters turned into uppercase (just like applying |gU| to | |
| 8248 the string). | |
| 8249 | |
| 15 | 8250 tr({src}, {fromstr}, {tostr}) *tr()* |
| 8251 The result is a copy of the {src} string with all characters | |
| 8252 which appear in {fromstr} replaced by the character in that | |
| 8253 position in the {tostr} string. Thus the first character in | |
| 8254 {fromstr} is translated into the first character in {tostr} | |
| 8255 and so on. Exactly like the unix "tr" command. | |
| 8256 This code also deals with multibyte characters properly. | |
| 8257 | |
| 8258 Examples: > | |
| 8259 echo tr("hello there", "ht", "HT") | |
| 8260 < returns "Hello THere" > | |
| 8261 echo tr("<blob>", "<>", "{}") | |
| 8262 < returns "{blob}" | |
| 8263 | |
| 1621 | 8264 trunc({expr}) *trunc()* |
| 1668 | 8265 Return the largest integral value with magnitude less than or |
| 1621 | 8266 equal to {expr} as a |Float| (truncate towards zero). |
| 8267 {expr} must evaluate to a |Float| or a |Number|. | |
| 8268 Examples: > | |
| 8269 echo trunc(1.456) | |
| 8270 < 1.0 > | |
| 8271 echo trunc(-5.456) | |
| 8272 < -5.0 > | |
| 8273 echo trunc(4.0) | |
| 8274 < 4.0 | |

| 8375 occupied by the character at that position, when the screen | |
| 8376 would be of unlimited width. When there is a <Tab> at the | |
| 8377 position, the returned Number will be the column at the end of | |
| 8378 the <Tab>. For example, for a <Tab> in column 1, with 'ts' | |
| 3445 | 8379 set to 8, it returns 8. |conceal| is ignored. |
| 1317 | 8380 For the byte position use |col()|. |
| 8381 For the use of {expr} see |col()|. | |
| 8382 When 'virtualedit' is used {expr} can be [lnum, col, off], where | |
| 703 | 8383 "off" is the offset in screen columns from the start of the |
| 1266 | 8384 character. E.g., a position within a <Tab> or after the last |
| 2965 | 8385 character. When "off" is omitted zero is used. |
| 7 | 8386 When Virtual editing is active in the current mode, a position |
| 8387 beyond the end of the line can be returned. |'virtualedit'| | |
| 8388 The accepted positions are: | |
| 8389 . the cursor position | |
| 8390 $ the end of the cursor line (the result is the | |
| 8391 number of displayed characters in the cursor line | |
| 8392 plus one) | |

| 8415 character-wise, line-wise, or block-wise Visual mode | |
| 8416 respectively. | |

| 8431 This can be used in mappings to handle the 'wildcharm' option | |
| 8432 gracefully. (Makes only sense with |mapmode-c| mappings). | |
| 8433 | |
| 8434 For example to make <c-j> work like <down> in wildmode, use: > | |

8493 in the window. This is counting screen lines from the top of |
| 7 | 8494 the window. The first line is one. |
| 531 | 8495 If the cursor was moved the view on the file will be updated |
| 8496 first, this may cause a scroll. | |
| 7 | 8497 |
| 8498 *winnr()* | |
| 20 | 8499 winnr([{arg}]) The result is a Number, which is the number of the current |
| 8500 window. The top window has number 1. | |
| 8501 When the optional argument is "$", the number of the | |
| 3967 | 8502 last window is returned (the window count). > |
| 8503 let window_count = winnr('$') | |
| 8504 < When the optional argument is "#", the number of the last | |
| 20 | 8505 accessed window is returned (where |CTRL-W_p| goes to). |
| 1156 | 8506 If there is no previous window or it is in another tab page 0 |
| 8507 is returned. | |
| 20 | 8508 The number can be used with |CTRL-W_w| and ":wincmd w" |
| 8509 |:wincmd|. | |
| 10734 | 8510 Also see |tabpagewinnr()| and |win_getid()|. |
| 7 | 8511 |
| 8512 *winrestcmd()* | |
| 8513 winrestcmd() Returns a sequence of |:resize| commands that should restore | |
| 8514 the current window sizes. Only works properly when no windows | |
| 712 | 8515 are opened or closed and the current window and tab page is |
| 8516 unchanged. | |
| 7 | 8517 Example: > |
| 8518 :let cmd = winrestcmd() | |
| 8519 :call MessWithWindowSizes() | |
| 8520 :exe cmd | |
| 712 | 8521 < |
| 8522 *winrestview()* | |
| 8523 winrestview({dict}) | |
| 8524 Uses the |Dictionary| returned by |winsaveview()| to restore | |
| 8525 the view of the current window. | |
| 5940 | 8526 Note: The {dict} does not have to contain all values, that are |
| 8527 returned by |winsaveview()|. If values are missing, those | |
| 8528 settings won't be restored. So you can use: > | |
| 8529 :call winrestview({'curswant': 4}) | |
| 8530 < | |
| 8531 This will only set the curswant value (the column the cursor | |
| 8532 wants to move on vertical movements) of the cursor to column 5 | |
| 8533 (yes, that is 5), while all other settings will remain the | |
| 8534 same. This is useful, if you set the cursor position manually. | |
| 8535 | |
| 712 | 8536 If you have changed the values the result is unpredictable. |
| 8537 If the window size changed the result won't be the same. | |
| 8538 | |
| 8539 *winsaveview()* | |
| 8540 winsaveview() Returns a |Dictionary| that contains information to restore | |
| 8541 the view of the current window. Use |winrestview()| to | |
| 8542 restore the view. | |
| 8543 This is useful if you have a mapping that jumps around in the | |
| 8544 buffer and you want to go back to the original view. | |
| 8545 This does not save fold information. Use the 'foldenable' | |
| 798 | 8546 option to temporarily switch off folding, so that folds are |

| 6341 | 8600 writefile({list}, {fname} [, {flags}]) |
| 685 | 8601 Write |List| {list} to file {fname}. Each list item is |
| 158 | 8602 separated with a NL. Each list item must be a String or |
| 8603 Number. | |
| 6341 | 8604 When {flags} contains "b" then binary mode is used: There will |
| 158 | 8605 not be a NL after the last list item. An empty item at the |
| 8606 end does cause the last line in the file to end in a NL. | |

| 6341 | 8610 :call writefile(["foo"], "event.log", "a") |
| 8611 :call writefile(["bar"], "event.log", "a") | |
| 8612 > | |
| 8613 < All NL characters are replaced with a NUL character. | |
| 158 | 8614 Inserting CR characters needs to be done before passing {list} |
| 8615 to writefile(). | |
| 8616 An existing file is overwritten, if possible. | |
| 8617 When the write fails -1 is returned, otherwise 0. There is an | |
| 8618 error message if the file can't be created or when writing | |
| 8619 fails. | |
| 8620 Also see |readfile()|. | |
| 8621 To copy a file byte for byte: > | |
| 8622 :let fl = readfile("foo", "b") | |
| 8623 :call writefile(fl, "foocopy", "b") | |

| 8626 xor({expr}, {expr}) *xor()* | |
| 8627 Bitwise XOR on the two arguments. The arguments are converted | |
| 8628 to a number. A List, Dict or Float argument causes an error. | |
| 8629 Example: > | |
| 8630 :let bits = xor(bits, 0x80) | |

| 8634 *feature-list* | |
| 6009 | 8635 There are four types of features: |
| 7 | 8636 1. Features that are only supported when they have been enabled when Vim |
| 8637 was compiled |+feature-list|. Example: > | |
| 8638 :if has("cindent") | |
| 8639 2. Features that are only supported when certain conditions have been met. | |
| 8640 Example: > | |
| 8641 :if has("gui_running") | |
| 8642 < *has-patch* | |
| 5814 | 8643 3. Included patches. The "patch123" feature means that patch 123 has been |
| 8644 included. Note that this form does not check the version of Vim, you need | |
| 8645 to inspect |v:version| for that. | |
| 8646 Example (checking version 6.2.148 or later): > | |
| 7 | 8647 :if v:version > 602 || v:version == 602 && has("patch148") |
| 5814 | 8648 < Note that it's possible for patch 147 to be omitted even though 148 is |
| 8649 included. | |
| 8650 | |
| 8651 4. Beyond a certain version or at a certain version and including a specific | |
| 5862 | 8652 patch. The "patch-7.4.237" feature means that the Vim version is 7.5 or |
| 8653 later, or it is version 7.4 and patch 237 was included. | |
| 8654 Note that this only works for patch 7.4.237 and later, before that you | |
| 8655 need to use the example above that checks v:version. Example: > | |
| 8656 :if has("patch-7.4.248") | |
| 5814 | 8657 < Note that it's possible for patch 147 to be omitted even though 148 is |
| 1156 | 8658 included. |

| 8850 *string-match* | |
| 8851 Matching a pattern in a String | |
| 8852 | |
| 8853 A regexp pattern as explained at |pattern| is normally used to find a match in | |
| 8854 the buffer lines. When a pattern is used to find a match in a String, almost | |
| 8855 everything works in the same way. The difference is that a String is handled | |
| 8856 like it is one line. When it contains a "\n" character, this is not seen as a | |
| 8857 line break for the pattern. It can be matched with a "\n" in the pattern, or | |
| 8858 with ".". Example: > | |
| 8859 :let a = "aaaa\nxxxx" | |
| 8860 :echo matchstr(a, "..\n..") | |
| 8861 aa | |
| 8862 xx | |
| 8863 :echo matchstr(a, "a.x") | |
| 8864 a | |
| 8865 x | |
| 8866 | |
| 8867 Don't forget that "^" will only match at the first character of the String and | |
| 8868 "$" at the last character of the string. They don't match after or before a | |
| 8869 "\n". | |
| 8870 | |
| 8871 ============================================================================== | |
| 8872 5. Defining functions *user-functions* | |
| 8873 | |
| 8874 New functions can be defined. These can be called just like builtin | |
| 8875 functions. The function executes a sequence of Ex commands. Normal mode | |
| 8876 commands can be executed with the |:normal| command. | |
| 8877 | |
| 8878 The function name must start with an uppercase letter, to avoid confusion with | |
| 8879 builtin functions. To prevent from using the same name in different scripts | |
| 8880 avoid obvious, short names. A good habit is to start the function name with | |
| 8881 the name of the script, e.g., "HTMLcolor()". | |
| 8882 | |
| 504 | 8883 It's also possible to use curly braces, see |curly-braces-names|. And the |
| 8884 |autoload| facility is useful to define a function only when it's called. | |
| 7 | 8885 |
| 8886 *local-function* | |
| 8887 A function local to a script must start with "s:". A local script function | |
| 8888 can only be called from within the script and from functions, user commands | |
| 8889 and autocommands defined in the script. It is also possible to call the | |
| 1698 | 8890 function from a mapping defined in the script, but then |<SID>| must be used |
| 7 | 8891 instead of "s:" when the mapping is expanded outside of the script. |
| 5862 | 8892 There are only script-local functions, no buffer-local or window-local |
| 8893 functions. | |
| 7 | 8894 |
| 8895 *:fu* *:function* *E128* *E129* *E123* | |
| 8896 :fu[nction] List all functions and their arguments. | |
| 8897 | |
| 8898 :fu[nction] {name} List function {name}. | |
| 685 | 8899 {name} can also be a |Dictionary| entry that is a |
| 8900 |Funcref|: > | |
| 114 | 8901 :function dict.init |
| 504 | 8902 |
| 8903 :fu[nction] /{pattern} List functions with a name matching {pattern}. | |
| 8904 Example that lists all functions ending with "File": > | |
| 8905 :function /File$ | |
| 482 | 8906 < |
| 8907 *:function-verbose* | |
| 8908 When 'verbose' is non-zero, listing a function will also display where it was | |
| 8909 last defined. Example: > | |
| 8910 | |
| 8911 :verbose function SetFileTypeSH | |
| 8912 function SetFileTypeSH(name) | |
| 8913 Last set from /usr/share/vim/vim-7.0/filetype.vim | |
| 8914 < | |
| 484 | 8915 See |:verbose-cmd| for more information. |

| 8920 must be made of alphanumeric characters and '_', and | |

| 8922 that using "b:" or "g:" is not allowed. (since patch | |
| 8923 7.4.260 E884 is given if the function name has a colon | |

| 7 | 8948 When the [range] argument is added, the function is |
| 8949 expected to take care of a range itself. The range is | |
| 8950 passed as "a:firstline" and "a:lastline". If [range] | |

9040 An argument can be defined by giving its name. In the function this can then |
| 133 | 9041 be used as "a:name" ("a:" for argument). |
| 1156 | 9042 *a:0* *a:1* *a:000* *E740* *...* |
| 133 | 9043 Up to 20 arguments can be given, separated by commas. After the named |
| 9044 arguments an argument "..." can be specified, which means that more arguments | |
| 9045 may optionally be following. In the function the extra arguments can be used | |
| 9046 as "a:1", "a:2", etc. "a:0" is set to the number of extra arguments (which | |
| 685 | 9047 can be 0). "a:000" is set to a |List| that contains these arguments. Note |
| 9048 that "a:1" is the same as "a:000[0]". | |

9067 function returns. Global variables need to be accessed with "g:". |
| 7 | 9068 |
| 9069 Example: > | |
| 9070 :function Table(title, ...) | |
| 9071 : echohl Title | |
| 9072 : echo a:title | |
| 9073 : echohl None | |

| 9075 : for s in a:000 | |
| 9076 : echon ' ' . s | |
| 9077 : endfor | |
| 7 | 9078 :endfunction |
| 9079 | |
| 9080 This function can then be called with: > | |
| 140 | 9081 call Table("Table", "line1", "line2") |
| 9082 call Table("Empty Table") | |
| 7 | 9083 |
| 1156 | 9084 To return more than one value, return a |List|: > |

| 1156 | 9087 : return ["fail", 0] |

| 1156 | 9089 : return ["ok", a:n1 / a:n2] |
| 7 | 9090 :endfunction |
| 9091 | |
| 9092 This function can then be called with: > | |
| 1156 | 9093 :let [success, div] = Compute(102, 6) |

| 7 | 9103 Without a range and for functions that accept a range, the |
| 9104 function is called once. When a range is given the cursor is | |
| 9105 positioned at the start of the first line before executing the | |
| 9106 function. | |
| 9107 When a range is given and the function doesn't handle it | |
| 9108 itself, the function is executed for each line in the range, | |
| 9109 with the cursor in the first column of that line. The cursor | |
| 9110 is left at the last line (possibly moved by the last function | |

9111 call). The arguments are re-evaluated for each line. Thus |
| 7 | 9112 this works: |
| 9113 *function-range-example* > | |
| 9114 :function Mynumber(arg) | |
| 9115 : echo line(".") . " " . a:arg | |
| 9116 :endfunction | |
| 9117 :1,5call Mynumber(getline(".")) | |
| 9118 < | |
| 9119 The "a:firstline" and "a:lastline" are defined anyway, they | |
| 9120 can be used to do something different at the start or end of | |
| 9121 the range. | |
| 9122 | |
| 9123 Example of a function that handles the range itself: > | |
| 9124 | |
| 9125 :function Cont() range | |
| 9126 : execute (a:firstline + 1) . "," . a:lastline . 's/^/\t\\ ' | |
| 9127 :endfunction | |
| 9128 :4,8call Cont() | |
| 9129 < | |
| 9130 This function inserts the continuation character "\" in front | |
| 9131 of all the lines in the range, except the first one. | |
| 9132 | |
| 1156 | 9133 When the function returns a composite value it can be further |
| 9134 dereferenced, but the range will not be used then. Example: > | |
| 9135 :4,8call GetDict().method() | |
| 9136 < Here GetDict() gets the range but method() does not. | |

| 9143 AUTOMATICALLY LOADING FUNCTIONS ~ | |
| 7 | 9144 *autoload-functions* |
| 9145 When using many or large functions, it's possible to automatically define them | |
| 161 | 9146 only when they are used. There are two methods: with an autocommand and with |
| 9147 the "autoload" directory in 'runtimepath'. | |
| 9148 | |
| 9149 | |
| 9150 Using an autocommand ~ | |
| 9151 | |
| 170 | 9152 This is introduced in the user manual, section |41.14|. |
| 9153 | |
| 161 | 9154 The autocommand is useful if you have a plugin that is a long Vim script file. |
| 9155 You can define the autocommand and quickly quit the script with |:finish|. | |
|

9156 That makes Vim startup faster. The autocommand should then load the same file |
| 161 | 9157 again, setting a variable to skip the |:finish| command. |
| 9158 | |
| 9159 Use the FuncUndefined autocommand event with a pattern that matches the | |
| 9160 function(s) to be defined. Example: > | |
| 7 | 9161 |
| 9162 :au FuncUndefined BufNet* source ~/vim/bufnetfuncs.vim | |
| 9163 | |
| 9164 The file "~/vim/bufnetfuncs.vim" should then define functions that start with | |
| 9165 "BufNet". Also see |FuncUndefined|. | |
| 9166 | |
| 161 | 9167 |
| 9168 Using an autoload script ~ | |
| 168 | 9169 *autoload* *E746* |
| 170 | 9170 This is introduced in the user manual, section |41.15|. |
| 9171 | |
| 161 | 9172 Using a script in the "autoload" directory is simpler, but requires using |
| 9173 exactly the right file name. A function that can be autoloaded has a name | |
| 9174 like this: > | |
| 9175 | |
| 270 | 9176 :call filename#funcname() |
| 161 | 9177 |
| 9178 When such a function is called, and it is not defined yet, Vim will search the | |
| 9179 "autoload" directories in 'runtimepath' for a script file called | |
| 9180 "filename.vim". For example "~/.vim/autoload/filename.vim". That file should | |
| 9181 then define the function like this: > | |
| 9182 | |
| 270 | 9183 function filename#funcname() |
| 161 | 9184 echo "Done!" |
| 9185 endfunction | |
| 9186 | |
| 530 | 9187 The file name and the name used before the # in the function must match |
| 161 | 9188 exactly, and the defined function must have the name exactly as it will be |
| 9189 called. | |
| 9190 | |
| 270 | 9191 It is possible to use subdirectories. Every # in the function name works like |
| 9192 a path separator. Thus when calling a function: > | |
| 9193 | |
| 9194 :call foo#bar#func() | |
| 161 | 9195 |
| 9196 Vim will look for the file "autoload/foo/bar.vim" in 'runtimepath'. | |
| 9197 | |
| 168 | 9198 This also works when reading a variable that has not been set yet: > |
| 9199 | |
| 270 | 9200 :let l = foo#bar#lvar |
| 168 | 9201 |
| 557 | 9202 However, when the autoload script was already loaded it won't be loaded again |
| 9203 for an unknown variable. | |
| 9204 | |
| 168 | 9205 When assigning a value to such a variable nothing special happens. This can |
| 9206 be used to pass settings to the autoload script before it's loaded: > | |
| 9207 | |
| 270 | 9208 :let foo#bar#toggle = 1 |
| 9209 :call foo#bar#func() | |
| 168 | 9210 |
| 164 | 9211 Note that when you make a mistake and call a function that is supposed to be |
| 9212 defined in an autoload script, but the script doesn't actually define the | |
| 9213 function, the script will be sourced every time you try to call the function. | |
| 168 | 9214 And you will get an error message every time. |
| 9215 | |
| 9216 Also note that if you have two script files, and one calls a function in the | |
| 1621 | 9217 other and vice versa, before the used function is defined, it won't work. |
| 168 | 9218 Avoid using the autoload functionality at the toplevel. |
| 161 | 9219 |
| 794 | 9220 Hint: If you distribute a bunch of scripts you can pack them together with the |
| 9221 |vimball| utility. Also read the user manual |distribute-script|. | |

9228 wrapped in braces {} like this: > |
| 7 | 9229 my_{adjective}_variable |
| 9230 | |
| 9231 When Vim encounters this, it evaluates the expression inside the braces, puts | |
| 9232 that in place of the expression, and re-interprets the whole as a variable | |
| 9233 name. So in the above example, if the variable "adjective" was set to | |
| 9234 "noisy", then the reference would be to "my_noisy_variable", whereas if | |
| 9235 "adjective" was set to "quiet", then it would be to "my_quiet_variable". | |
| 9236 | |
| 9237 One application for this is to create a set of variables governed by an option | |

9238 value. For example, the statement > |
| 7 | 9239 echo my_{&background}_message |
| 9240 | |
| 9241 would output the contents of "my_dark_message" or "my_light_message" depending | |
| 9242 on the current value of 'background'. | |
| 9243 | |
| 9244 You can use multiple brace pairs: > | |
| 9245 echo my_{adverb}_{adjective}_message | |
| 9246 ..or even nest them: > | |
| 9247 echo my_{ad{end_of_word}}_message | |
| 9248 where "end_of_word" is either "verb" or "jective". | |
| 9249 | |
| 9250 However, the expression inside the braces must evaluate to a valid single | |
| 236 | 9251 variable name, e.g. this is invalid: > |
| 7 | 9252 :let foo='a + b' |
| 9253 :echo c{foo}d | |
| 9254 .. since the result of expansion is "ca + bd", which is not a variable name. | |
| 9255 | |
| 9256 *curly-braces-function-names* | |
| 9257 You can call and define functions by an evaluated name in a similar way. | |
| 9258 Example: > | |
| 9259 :let func_end='whizz' | |
| 9260 :call my_func_{func_end}(parameter) | |
| 9261 | |
| 9262 This would call the function "my_func_whizz(parameter)". | |

| 7 | 9313 |
| 9314 :let @{reg-name} = {expr1} *:let-register* *:let-@* | |
| 9315 Write the result of the expression {expr1} in register | |

| 9317 must be the name of a writable register (see | |
| 9318 |registers|). "@@" can be used for the unnamed | |
| 9319 register, "@/" for the search pattern. | |
| 9320 If the result of {expr1} ends in a <CR> or <NL>, the | |
| 9321 register will be linewise, otherwise it will be set to | |
| 9322 characterwise. | |
| 9323 This can be used to clear the last search pattern: > | |
| 9324 :let @/ = "" | |
| 9325 < This is different from searching for an empty string, | |
| 9326 that would match everywhere. | |

9329 Append {expr1} to register {reg-name}. If the |
| 114 | 9330 register was empty it's like setting it to {expr1}. |
| 9331 | |
| 1156 | 9332 :let &{option-name} = {expr1} *:let-option* *:let-&* |
| 7 | 9333 Set option {option-name} to the result of the |
| 68 | 9334 expression {expr1}. A String or Number value is |
| 9335 always converted to the type of the option. | |
| 7 | 9336 For an option local to a window or buffer the effect |
| 9337 is just like using the |:set| command: both the local | |
| 555 | 9338 value and the global value are changed. |

9458 variable {name}". |
| 148 | 9459 |
| 685 | 9460 [depth] is relevant when locking a |List| or |
| 9461 |Dictionary|. It specifies how deep the locking goes: | |
| 9462 1 Lock the |List| or |Dictionary| itself, | |
| 148 | 9463 cannot add or remove items, but can |
| 9464 still change their values. | |
| 9465 2 Also lock the values, cannot change | |
| 685 | 9466 the items. If an item is a |List| or |
| 9467 |Dictionary|, cannot add or remove | |
| 148 | 9468 items, but can still change the |
| 9469 values. | |
| 685 | 9470 3 Like 2 but for the |List| / |
| 9471 |Dictionary| in the |List| / | |
| 9472 |Dictionary|, one level deeper. | |
| 9473 The default [depth] is 2, thus when {name} is a |List| | |
| 9474 or |Dictionary| the values cannot be changed. | |
| 148 | 9475 *E743* |
| 9476 For unlimited depth use [!] and omit [depth]. | |
| 9477 However, there is a maximum depth of 100 to catch | |
| 9478 loops. | |
| 9479 | |
| 685 | 9480 Note that when two variables refer to the same |List| |
| 9481 and you lock one of them, the |List| will also be | |
| 819 | 9482 locked when used through the other variable. |
| 9483 Example: > | |
| 148 | 9484 :let l = [0, 1, 2, 3] |
| 9485 :let cl = l | |
| 9486 :lockvar l | |
| 9487 :let cl[1] = 99 " won't work! | |
| 9488 < You may want to make a copy of a list to avoid this. | |
| 9489 See |deepcopy()|. | |
| 9490 | |
| 9491 | |
| 9492 :unlo[ckvar][!] [depth] {name} ... *:unlockvar* *:unlo* | |
| 9493 Unlock the internal variable {name}. Does the | |
| 9494 opposite of |:lockvar|. | |
| 9495 | |
| 9496 | |
| 7 | 9497 :if {expr1} *:if* *:endif* *:en* *E171* *E579* *E580* |
| 9498 :en[dif] Execute the commands until the next matching ":else" | |
| 9499 or ":endif" if {expr1} evaluates to non-zero. | |
| 9500 | |
| 9501 From Vim version 4.5 until 5.0, every Ex command in | |
| 9502 between the ":if" and ":endif" is ignored. These two | |
| 9503 commands were just to allow for future expansions in a | |

9504 backward compatible way. Nesting was allowed. Note |
| 7 | 9505 that any ":else" or ":elseif" was ignored, the "else" |
| 9506 part was not executed either. | |
| 9507 | |
| 9508 You can use this to remain compatible with older | |
| 9509 versions: > | |
| 9510 :if version >= 500 | |
| 9511 : version-5-specific-commands | |
| 9512 :endif | |
| 9513 < The commands still need to be parsed to find the | |
| 9514 "endif". Sometimes an older Vim has a problem with a | |
| 9515 new command. For example, ":silent" is recognized as | |
| 9516 a ":substitute" command. In that case ":execute" can | |
| 9517 avoid problems: > | |
| 9518 :if version >= 600 | |
| 9519 : execute "silent 1,$delete" | |
| 9520 :endif | |
| 9521 < | |
| 9522 NOTE: The ":append" and ":insert" commands don't work | |
| 9523 properly in between ":if" and ":endif". | |
| 9524 | |
| 9525 *:else* *:el* *E581* *E583* | |
| 9526 :el[se] Execute the commands until the next matching ":else" | |
| 9527 or ":endif" if they previously were not being | |
| 9528 executed. | |
| 9529 | |
| 9530 *:elseif* *:elsei* *E582* *E584* | |
| 9531 :elsei[f] {expr1} Short for ":else" ":if", with the addition that there | |
| 9532 is no extra ":endif". | |
| 9533 | |
| 9534 :wh[ile] {expr1} *:while* *:endwhile* *:wh* *:endw* | |
| 114 | 9535 *E170* *E585* *E588* *E733* |
| 7 | 9536 :endw[hile] Repeat the commands between ":while" and ":endwhile", |
| 9537 as long as {expr1} evaluates to non-zero. | |
| 9538 When an error is detected from a command inside the | |
| 9539 loop, execution continues after the "endwhile". | |
| 75 | 9540 Example: > |
| 9541 :let lnum = 1 | |
| 9542 :while lnum <= line("$") | |
| 9543 :call FixLine(lnum) | |
| 9544 :let lnum = lnum + 1 | |
| 9545 :endwhile | |
| 9546 < | |
| 7 | 9547 NOTE: The ":append" and ":insert" commands don't work |
| 99 | 9548 properly inside a ":while" and ":for" loop. |
| 75 | 9549 |
| 114 | 9550 :for {var} in {list} *:for* *E690* *E732* |
| 75 | 9551 :endfo[r] *:endfo* *:endfor* |
| 9552 Repeat the commands between ":for" and ":endfor" for | |
| 158 | 9553 each item in {list}. Variable {var} is set to the |
| 79 | 9554 value of each item. |
| 9555 When an error is detected for a command inside the | |
| 75 | 9556 loop, execution continues after the "endfor". |
| 464 | 9557 Changing {list} inside the loop affects what items are |
| 9558 used. Make a copy if this is unwanted: > | |
| 79 | 9559 :for item in copy(mylist) |
| 9560 < When not making a copy, Vim stores a reference to the | |
| 9561 next item in the list, before executing the commands | |

| 9596 before the matching |:finally| (if present), the | |
| 9597 commands following the ":finally" up to the matching | |
| 9598 |:endtry| are executed first. This process applies to | |

| 9605 executed across ":source" commands, function calls, | |
| 9606 or autocommand invocations. | |
| 9607 | |
| 9608 When an error or interrupt is detected and there is | |
| 9609 a |:finally| command following, execution continues | |
| 9610 after the ":finally". Otherwise, or when the | |
| 9611 ":endtry" is reached thereafter, the next | |
| 9612 (dynamically) surrounding ":try" is checked for | |
| 9613 a corresponding ":finally" etc. Then the script | |
| 9614 processing is terminated. (Whether a function | |
| 9615 definition has an "abort" argument does not matter.) | |
| 9616 Example: > | |
| 9617 :try | edit too much | finally | echo "cleanup" | endtry | |
| 9618 :echo "impossible" " not reached, script terminated above | |
| 9619 < | |
| 9620 Moreover, an error or interrupt (dynamically) inside | |
| 9621 ":try" and ":endtry" is converted to an exception. It | |
| 9622 can be caught as if it were thrown by a |:throw| | |
| 9623 command (see |:catch|). In this case, the script | |
| 9624 processing is not terminated. | |
| 9625 | |
| 9626 The value "Vim:Interrupt" is used for an interrupt | |
| 9627 exception. An error in a Vim command is converted | |
| 9628 to a value of the form "Vim({command}):{errmsg}", | |
| 9629 other errors are converted to a value of the form | |
| 9630 "Vim:{errmsg}". {command} is the full command name, | |
| 9631 and {errmsg} is the message that is displayed if the | |
| 9632 error exception is not caught, always beginning with | |
| 9633 the error number. | |

9639 :cat[ch] /{pattern}/ The following commands until the next |:catch|, |
| 7 | 9640 |:finally|, or |:endtry| that belongs to the same |
| 9641 |:try| as the ":catch" are executed when an exception | |
| 9642 matching {pattern} is being thrown and has not yet | |
| 9643 been caught by a previous ":catch". Otherwise, these | |
| 9644 commands are skipped. | |
| 9645 When {pattern} is omitted all errors are caught. | |
| 9646 Examples: > | |
| 9647 :catch /^Vim:Interrupt$/ " catch interrupts (CTRL-C) | |
| 9648 :catch /^Vim\%((\a\+)\)\=:E/ " catch all Vim errors | |
| 9649 :catch /^Vim\%((\a\+)\)\=:/ " catch errors and interrupts | |
| 9650 :catch /^Vim(write):/ " catch all errors in :write | |
| 9651 :catch /^Vim\%((\a\+)\)\=:E123/ " catch error E123 | |
| 9652 :catch /my-exception/ " catch user exception | |
| 9653 :catch /.*/ " catch everything | |
| 9654 :catch " same as /.*/ | |
| 9655 < | |
| 9656 Another character can be used instead of / around the | |
| 9657 {pattern}, so long as it does not have a special | |
| 9658 meaning (e.g., '|' or '"') and doesn't occur inside | |
| 9659 {pattern}. | |
| 5814 | 9660 Information about the exception is available in |
| 9661 |v:exception|. Also see |throw-variables|. | |
| 7 | 9662 NOTE: It is not reliable to ":catch" the TEXT of |
| 9663 an error message because it may vary in different | |
| 9664 locales. | |
| 9665 | |
| 9666 *:fina* *:finally* *E606* *E607* | |
| 9667 :fina[lly] The following commands until the matching |:endtry| | |
| 9668 are executed whenever the part between the matching | |
| 9669 |:try| and the ":finally" is left: either by falling | |
| 9670 through to the ":finally" or by a |:continue|, | |
| 9671 |:break|, |:finish|, or |:return|, or by an error or | |
| 9672 interrupt or exception (see |:throw|). | |
| 9673 | |
| 9674 *:th* *:throw* *E608* | |
| 9675 :th[row] {expr1} The {expr1} is evaluated and thrown as an exception. | |
| 9676 If the ":throw" is used after a |:try| but before the | |
| 9677 first corresponding |:catch|, commands are skipped | |
| 9678 until the first ":catch" matching {expr1} is reached. | |
| 9679 If there is no such ":catch" or if the ":throw" is | |
| 9680 used after a ":catch" but before the |:finally|, the | |
| 9681 commands following the ":finally" (if present) up to | |
| 9682 the matching |:endtry| are executed. If the ":throw" | |
| 9683 is after the ":finally", commands up to the ":endtry" | |
| 9684 are skipped. At the ":endtry", this process applies | |
| 9685 again for the next dynamically surrounding ":try" | |
| 9686 (which may be found in a calling function or sourcing | |
| 9687 script), until a matching ":catch" has been found. | |
| 9688 If the exception is not caught, the command processing | |
| 9689 is terminated. | |
| 9690 Example: > | |
| 9691 :try | throw "oops" | catch /^oo/ | echo "caught" | endtry | |
| 2725 | 9692 < Note that "catch" may need to be on a separate line |
| 9693 for when an error causes the parsing to skip the whole | |
| 9694 line and not see the "|" that separates the commands. | |
| 7 | 9695 |
| 9696 *:ec* *:echo* | |
| 9697 :ec[ho] {expr1} .. Echoes each {expr1}, with a space in between. The | |
| 9698 first {expr1} starts on a new line. | |
| 9699 Also see |:comment|. | |
| 9700 Use "\n" to start a new line. Use "\r" to move the | |
| 9701 cursor to the first column. | |
| 9702 Uses the highlighting set by the |:echohl| command. | |
| 9703 Cannot be followed by a comment. | |
| 9704 Example: > | |
| 9705 :echo "the value of 'shell' is" &shell | |
| 1156 | 9706 < *:echo-redraw* |
| 9707 A later redraw may make the message disappear again. | |
| 9708 And since Vim mostly postpones redrawing until it's | |
| 9709 finished with a sequence of commands this happens | |
| 9710 quite often. To avoid that a command from before the | |
| 9711 ":echo" causes a redraw afterwards (redraws are often | |
| 9712 postponed until you type something), force a redraw | |
| 9713 with the |:redraw| command. Example: > | |
| 7 | 9714 :new | redraw | echo "there is a new window" |
| 9715 < | |
| 9716 *:echon* | |
| 9717 :echon {expr1} .. Echoes each {expr1}, without anything added. Also see | |
| 9718 |:comment|. | |
| 9719 Uses the highlighting set by the |:echohl| command. | |
| 9720 Cannot be followed by a comment. | |
| 9721 Example: > | |
| 9722 :echon "the value of 'shell' is " &shell | |
| 9723 < | |
| 9724 Note the difference between using ":echo", which is a | |
| 9725 Vim command, and ":!echo", which is an external shell | |
| 9726 command: > | |
| 9727 :!echo % --> filename | |
| 9728 < The arguments of ":!" are expanded, see |:_%|. > | |
| 9729 :!echo "%" --> filename or "filename" | |
| 9730 < Like the previous example. Whether you see the double | |
| 9731 quotes or not depends on your 'shell'. > | |
| 9732 :echo % --> nothing | |
| 9733 < The '%' is an illegal character in an expression. > | |
| 9734 :echo "%" --> % | |
| 9735 < This just echoes the '%' character. > | |
| 9736 :echo expand("%") --> filename | |
| 9737 < This calls the expand() function to expand the '%'. | |
| 9738 | |
| 9739 *:echoh* *:echohl* | |
| 9740 :echoh[l] {name} Use the highlight group {name} for the following | |
| 9741 |:echo|, |:echon| and |:echomsg| commands. Also used | |
| 9742 for the |input()| prompt. Example: > | |
| 9743 :echohl WarningMsg | echo "Don't panic!" | echohl None | |
| 9744 < Don't forget to set the group back to "None", | |
| 9745 otherwise all following echo's will be highlighted. | |
| 9746 | |
| 9747 *:echom* *:echomsg* | |
| 9748 :echom[sg] {expr1} .. Echo the expression(s) as a true message, saving the | |
| 9749 message in the |message-history|. | |
| 9750 Spaces are placed between the arguments as with the | |
| 9751 |:echo| command. But unprintable characters are | |
| 9752 displayed, not interpreted. | |
| 1156 | 9753 The parsing works slightly different from |:echo|, |
| 9754 more like |:execute|. All the expressions are first | |
| 9755 evaluated and concatenated before echoing anything. | |
| 9756 The expressions must evaluate to a Number or String, a | |
| 9757 Dictionary or List causes an error. | |
| 7 | 9758 Uses the highlighting set by the |:echohl| command. |
| 9759 Example: > | |
| 9760 :echomsg "It's a Zizzer Zazzer Zuzz, as you can plainly see." | |
| 1156 | 9761 < See |:echo-redraw| to avoid the message disappearing |
| 9762 when the screen is redrawn. | |
| 7 | 9763 *:echoe* *:echoerr* |
| 9764 :echoe[rr] {expr1} .. Echo the expression(s) as an error message, saving the | |
| 9765 message in the |message-history|. When used in a | |
| 9766 script or function the line number will be added. | |
| 9767 Spaces are placed between the arguments as with the | |

9768 :echo command. When used inside a try conditional, |
| 7 | 9769 the message is raised as an error exception instead |
| 9770 (see |try-echoerr|). | |

| 9777 *:exe* *:execute* | |
| 9778 :exe[cute] {expr1} .. Executes the string that results from the evaluation | |
| 2152 | 9779 of {expr1} as an Ex command. |
| 9780 Multiple arguments are concatenated, with a space in | |
| 9781 between. To avoid the extra space use the "." | |
| 9782 operator to concatenate strings into one argument. | |
| 9783 {expr1} is used as the processed command, command line | |
| 9784 editing keys are not recognized. | |
| 7 | 9785 Cannot be followed by a comment. |
| 9786 Examples: > | |
| 2152 | 9787 :execute "buffer" nextbuf |
| 9788 :execute "normal" count . "w" | |
| 7 | 9789 < |
| 9790 ":execute" can be used to append a command to commands | |
| 9791 that don't accept a '|'. Example: > | |
| 9792 :execute '!ls' | echo "theend" | |
| 9793 | |
| 9794 < ":execute" is also a nice way to avoid having to type | |
| 9795 control characters in a Vim script for a ":normal" | |
| 9796 command: > | |
| 9797 :execute "normal ixxx\<Esc>" | |

| 5763 | 9808 starting or ending "if", "while" and "for" does not |

| 9834 ============================================================================== | |
| 9835 8. Exception handling *exception-handling* | |
| 9836 | |
| 9837 The Vim script language comprises an exception handling feature. This section | |
| 9838 explains how it can be used in a Vim script. | |
| 9839 | |
| 9840 Exceptions may be raised by Vim on an error or on interrupt, see | |
| 9841 |catch-errors| and |catch-interrupt|. You can also explicitly throw an | |
| 9842 exception by using the ":throw" command, see |throw-catch|. | |
| 9843 | |
| 9844 | |
| 9845 TRY CONDITIONALS *try-conditionals* | |
| 9846 | |
| 9847 Exceptions can be caught or can cause cleanup code to be executed. You can | |
| 9848 use a try conditional to specify catch clauses (that catch exceptions) and/or | |
| 9849 a finally clause (to be executed for cleanup). | |
| 9850 A try conditional begins with a |:try| command and ends at the matching | |
| 9851 |:endtry| command. In between, you can use a |:catch| command to start | |
| 9852 a catch clause, or a |:finally| command to start a finally clause. There may | |
| 9853 be none or multiple catch clauses, but there is at most one finally clause, | |
| 9854 which must not be followed by any catch clauses. The lines before the catch | |
| 9855 clauses and the finally clause is called a try block. > | |
| 9856 | |
| 9857 :try | |
| 1621 | 9858 : ... |
| 9859 : ... TRY BLOCK | |
| 9860 : ... | |
| 7 | 9861 :catch /{pattern}/ |
| 1621 | 9862 : ... |
| 9863 : ... CATCH CLAUSE | |
| 9864 : ... | |
| 7 | 9865 :catch /{pattern}/ |
| 1621 | 9866 : ... |
| 9867 : ... CATCH CLAUSE | |
| 9868 : ... | |
| 7 | 9869 :finally |
| 1621 | 9870 : ... |
| 9871 : ... FINALLY CLAUSE | |
| 9872 : ... | |
| 7 | 9873 :endtry |
| 9874 | |
| 9875 The try conditional allows to watch code for exceptions and to take the | |
| 9876 appropriate actions. Exceptions from the try block may be caught. Exceptions | |
| 9877 from the try block and also the catch clauses may cause cleanup actions. | |
| 9878 When no exception is thrown during execution of the try block, the control | |
| 9879 is transferred to the finally clause, if present. After its execution, the | |
| 9880 script continues with the line following the ":endtry". | |
| 9881 When an exception occurs during execution of the try block, the remaining | |
| 9882 lines in the try block are skipped. The exception is matched against the | |
| 9883 patterns specified as arguments to the ":catch" commands. The catch clause | |
| 9884 after the first matching ":catch" is taken, other catch clauses are not | |
| 9885 executed. The catch clause ends when the next ":catch", ":finally", or | |
| 9886 ":endtry" command is reached - whatever is first. Then, the finally clause | |
| 9887 (if present) is executed. When the ":endtry" is reached, the script execution | |
| 9888 continues in the following line as usual. | |
| 9889 When an exception that does not match any of the patterns specified by the | |
| 9890 ":catch" commands is thrown in the try block, the exception is not caught by | |
| 9891 that try conditional and none of the catch clauses is executed. Only the | |
| 9892 finally clause, if present, is taken. The exception pends during execution of | |
| 9893 the finally clause. It is resumed at the ":endtry", so that commands after | |
| 9894 the ":endtry" are not executed and the exception might be caught elsewhere, | |
| 9895 see |try-nesting|. | |
| 9896 When during execution of a catch clause another exception is thrown, the | |

9897 remaining lines in that catch clause are not executed. The new exception is |
| 7 | 9898 not matched against the patterns in any of the ":catch" commands of the same |
| 9899 try conditional and none of its catch clauses is taken. If there is, however, | |
| 9900 a finally clause, it is executed, and the exception pends during its | |
| 9901 execution. The commands following the ":endtry" are not executed. The new | |

9904 thrown, the remaining lines in the finally clause are skipped. If the finally |
| 7 | 9905 clause has been taken because of an exception from the try block or one of the |
| 9906 catch clauses, the original (pending) exception is discarded. The commands | |
| 9907 following the ":endtry" are not executed, and the exception from the finally | |
| 9908 clause is propagated and can be caught elsewhere, see |try-nesting|. | |
| 9909 | |
| 9910 The finally clause is also executed, when a ":break" or ":continue" for | |
| 9911 a ":while" loop enclosing the complete try conditional is executed from the | |
| 9912 try block or a catch clause. Or when a ":return" or ":finish" is executed | |
| 9913 from the try block or a catch clause of a try conditional in a function or | |
| 9914 sourced script, respectively. The ":break", ":continue", ":return", or | |
| 9915 ":finish" pends during execution of the finally clause and is resumed when the | |
| 9916 ":endtry" is reached. It is, however, discarded when an exception is thrown | |
| 9917 from the finally clause. | |
| 9918 When a ":break" or ":continue" for a ":while" loop enclosing the complete | |
| 9919 try conditional or when a ":return" or ":finish" is encountered in the finally | |
| 9920 clause, the rest of the finally clause is skipped, and the ":break", | |
| 9921 ":continue", ":return" or ":finish" is executed as usual. If the finally | |
| 9922 clause has been taken because of an exception or an earlier ":break", | |
| 9923 ":continue", ":return", or ":finish" from the try block or a catch clause, | |
| 9924 this pending exception or command is discarded. | |
| 9925 | |
| 9926 For examples see |throw-catch| and |try-finally|. | |
| 9927 | |
| 9928 | |
| 9929 NESTING OF TRY CONDITIONALS *try-nesting* | |
| 9930 | |
| 9931 Try conditionals can be nested arbitrarily. That is, a complete try | |
| 9932 conditional can be put into the try block, a catch clause, or the finally | |
| 9933 clause of another try conditional. If the inner try conditional does not | |
| 9934 catch an exception thrown in its try block or throws a new exception from one | |
| 9935 of its catch clauses or its finally clause, the outer try conditional is | |
| 9936 checked according to the rules above. If the inner try conditional is in the | |
| 9937 try block of the outer try conditional, its catch clauses are checked, but | |
|

9938 otherwise only the finally clause is executed. It does not matter for |
| 7 | 9939 nesting, whether the inner try conditional is directly contained in the outer |
| 9940 one, or whether the outer one sources a script or calls a function containing | |
| 9941 the inner try conditional. | |
| 9942 | |
| 9943 When none of the active try conditionals catches an exception, just their | |
| 9944 finally clauses are executed. Thereafter, the script processing terminates. | |
| 9945 An error message is displayed in case of an uncaught exception explicitly | |
| 9946 thrown by a ":throw" command. For uncaught error and interrupt exceptions | |
| 9947 implicitly raised by Vim, the error message(s) or interrupt message are shown | |
| 9948 as usual. | |
| 9949 | |
| 9950 For examples see |throw-catch|. | |
| 9951 | |
| 9952 | |
| 9953 EXAMINING EXCEPTION HANDLING CODE *except-examine* | |
| 9954 | |
| 9955 Exception handling code can get tricky. If you are in doubt what happens, set | |
| 9956 'verbose' to 13 or use the ":13verbose" command modifier when sourcing your | |
| 9957 script file. Then you see when an exception is thrown, discarded, caught, or | |
| 9958 finished. When using a verbosity level of at least 14, things pending in | |
| 9959 a finally clause are also shown. This information is also given in debug mode | |
| 9960 (see |debug-scripts|). | |
| 9961 | |
| 9962 | |
| 9963 THROWING AND CATCHING EXCEPTIONS *throw-catch* | |
| 9964 | |
| 9965 You can throw any number or string as an exception. Use the |:throw| command | |
| 9966 and pass the value to be thrown as argument: > | |
| 9967 :throw 4711 | |
| 9968 :throw "string" | |
| 9969 < *throw-expression* | |
| 9970 You can also specify an expression argument. The expression is then evaluated | |
| 9971 first, and the result is thrown: > | |
| 9972 :throw 4705 + strlen("string") | |
| 9973 :throw strpart("strings", 0, 6) | |
| 9974 | |
| 9975 An exception might be thrown during evaluation of the argument of the ":throw" | |
| 9976 command. Unless it is caught there, the expression evaluation is abandoned. | |
| 9977 The ":throw" command then does not throw a new exception. | |
| 9978 Example: > | |
| 9979 | |
| 9980 :function! Foo(arg) | |
| 9981 : try | |
| 9982 : throw a:arg | |
| 9983 : catch /foo/ | |
| 9984 : endtry | |
| 9985 : return 1 | |
| 9986 :endfunction | |
| 9987 : | |
| 9988 :function! Bar() | |
| 9989 : echo "in Bar" | |
| 9990 : return 4710 | |
| 9991 :endfunction | |
| 9992 : | |
| 9993 :throw Foo("arrgh") + Bar() | |
| 9994 | |
| 9995 This throws "arrgh", and "in Bar" is not displayed since Bar() is not | |
| 9996 executed. > | |
| 9997 :throw Foo("foo") + Bar() | |

10001 abandoned by an (uncaught) exception during the expression evaluation. The |
| 7 | 10002 exception is then propagated to the caller of the command. |
| 10003 Example: > | |
| 10004 | |
| 10005 :if Foo("arrgh") | |
| 10006 : echo "then" | |
| 10007 :else | |
| 10008 : echo "else" | |
| 10009 :endif | |
| 10010 | |
| 10011 Here neither of "then" or "else" is displayed. | |
| 10012 | |
| 10013 *catch-order* | |
| 10014 Exceptions can be caught by a try conditional with one or more |:catch| | |
| 10015 commands, see |try-conditionals|. The values to be caught by each ":catch" | |
| 10016 command can be specified as a pattern argument. The subsequent catch clause | |
| 10017 gets executed when a matching exception is caught. | |
| 10018 Example: > | |
| 10019 | |
| 10020 :function! Foo(value) | |
| 10021 : try | |
| 10022 : throw a:value | |
| 10023 : catch /^\d\+$/ | |
| 10024 : echo "Number thrown" | |
| 10025 : catch /.*/ | |
| 10026 : echo "String thrown" | |
| 10027 : endtry | |
| 10028 :endfunction | |
| 10029 : | |
| 10030 :call Foo(0x1267) | |
| 10031 :call Foo('string') | |
| 10032 | |
| 10033 The first call to Foo() displays "Number thrown", the second "String thrown". | |
| 10034 An exception is matched against the ":catch" commands in the order they are | |
| 10035 specified. Only the first match counts. So you should place the more | |
| 10036 specific ":catch" first. The following order does not make sense: > | |
| 10037 | |
| 10038 : catch /.*/ | |
| 10039 : echo "String thrown" | |
| 10040 : catch /^\d\+$/ | |
| 10041 : echo "Number thrown" | |
| 10042 | |
| 10043 The first ":catch" here matches always, so that the second catch clause is | |
| 10044 never taken. | |
| 10045 | |
| 10046 *throw-variables* | |
| 10047 If you catch an exception by a general pattern, you may access the exact value | |
| 10048 in the variable |v:exception|: > | |
| 10049 | |
| 10050 : catch /^\d\+$/ | |
| 10051 : echo "Number thrown. Value is" v:exception | |
| 10052 | |
| 10053 You may also be interested where an exception was thrown. This is stored in | |
| 10054 |v:throwpoint|. Note that "v:exception" and "v:throwpoint" are valid for the | |
| 10055 exception most recently caught as long it is not finished. | |
| 10056 Example: > | |
| 10057 | |
| 10058 :function! Caught() | |
| 10059 : if v:exception != "" | |
| 10060 : echo 'Caught "' . v:exception . '" in ' . v:throwpoint | |
| 10061 : else | |
| 10062 : echo 'Nothing caught' | |
| 10063 : endif | |
| 10064 :endfunction | |
| 10065 : | |
| 10066 :function! Foo() | |
| 10067 : try | |
| 10068 : try | |
| 10069 : try | |
| 10070 : throw 4711 | |
| 10071 : finally | |
| 10072 : call Caught() | |
| 10073 : endtry | |
| 10074 : catch /.*/ | |
| 10075 : call Caught() | |
| 10076 : throw "oops" | |
| 10077 : endtry | |
| 10078 : catch /.*/ | |
| 10079 : call Caught() | |
| 10080 : finally | |
| 10081 : call Caught() | |
| 10082 : endtry | |
| 10083 :endfunction | |
| 10084 : | |
| 10085 :call Foo() | |
| 10086 | |
| 10087 This displays > | |
| 10088 | |
| 10089 Nothing caught | |
| 10090 Caught "4711" in function Foo, line 4 | |
| 10091 Caught "oops" in function Foo, line 10 | |
| 10092 Nothing caught | |
| 10093 | |
| 10094 A practical example: The following command ":LineNumber" displays the line | |
| 10095 number in the script or function where it has been used: > | |
| 10096 | |
| 10097 :function! LineNumber() | |
| 10098 : return substitute(v:throwpoint, '.*\D\(\d\+\).*', '\1', "") | |
| 10099 :endfunction | |
| 10100 :command! LineNumber try | throw "" | catch | echo LineNumber() | endtry | |
| 10101 < | |
| 10102 *try-nested* | |
| 10103 An exception that is not caught by a try conditional can be caught by | |
| 10104 a surrounding try conditional: > | |
| 10105 | |
| 10106 :try | |
| 10107 : try | |
| 10108 : throw "foo" | |
| 10109 : catch /foobar/ | |
| 10110 : echo "foobar" | |
| 10111 : finally | |
| 10112 : echo "inner finally" | |
| 10113 : endtry | |
| 10114 :catch /foo/ | |
| 10115 : echo "foo" | |
| 10116 :endtry | |
| 10117 | |
| 10118 The inner try conditional does not catch the exception, just its finally | |
| 10119 clause is executed. The exception is then caught by the outer try | |
| 10120 conditional. The example displays "inner finally" and then "foo". | |
| 10121 | |
| 10122 *throw-from-catch* | |
| 10123 You can catch an exception and throw a new one to be caught elsewhere from the | |
| 10124 catch clause: > | |
| 10125 | |
| 10126 :function! Foo() | |
| 10127 : throw "foo" | |
| 10128 :endfunction | |
| 10129 : | |
| 10130 :function! Bar() | |
| 10131 : try | |
| 10132 : call Foo() | |
| 10133 : catch /foo/ | |
| 10134 : echo "Caught foo, throw bar" | |
| 10135 : throw "bar" | |
| 10136 : endtry | |
| 10137 :endfunction | |
| 10138 : | |
| 10139 :try | |
| 10140 : call Bar() | |
| 10141 :catch /.*/ | |
| 10142 : echo "Caught" v:exception | |
| 10143 :endtry | |
| 10144 | |
| 10145 This displays "Caught foo, throw bar" and then "Caught bar". | |
| 10146 | |
| 10147 *rethrow* | |
| 10148 There is no real rethrow in the Vim script language, but you may throw | |
| 10149 "v:exception" instead: > | |
| 10150 | |
| 10151 :function! Bar() | |
| 10152 : try | |
| 10153 : call Foo() | |
| 10154 : catch /.*/ | |
| 10155 : echo "Rethrow" v:exception | |
| 10156 : throw v:exception | |
| 10157 : endtry | |
| 10158 :endfunction | |
| 10159 < *try-echoerr* | |
| 10160 Note that this method cannot be used to "rethrow" Vim error or interrupt | |
| 10161 exceptions, because it is not possible to fake Vim internal exceptions. | |
| 10162 Trying so causes an error exception. You should throw your own exception | |
| 10163 denoting the situation. If you want to cause a Vim error exception containing | |
| 10164 the original error exception value, you can use the |:echoerr| command: > | |
| 10165 | |
| 10166 :try | |
| 10167 : try | |
| 10168 : asdf | |
| 10169 : catch /.*/ | |
| 10170 : echoerr v:exception | |
| 10171 : endtry | |
| 10172 :catch /.*/ | |
| 10173 : echo v:exception | |
| 10174 :endtry | |
| 10175 | |
| 10176 This code displays | |

10185 an inconsistent state. The same may happen to you in the development phase of |
| 7 | 10186 a script when an error occurs or you explicitly throw an exception without |
| 10187 catching it. You can solve these problems by using a try conditional with | |
| 10188 a finally clause for restoring the settings. Its execution is guaranteed on | |
| 10189 normal control flow, on error, on an explicit ":throw", and on interrupt. | |

10191 to exceptions. When not caught, they terminate the script after the finally |
| 7 | 10192 clause has been executed.) |
| 10193 Example: > | |
| 10194 | |
| 10195 :try | |
| 10196 : let s:saved_ts = &ts | |
| 10197 : set ts=17 | |
| 10198 : | |
| 10199 : " Do the hard work here. | |
| 10200 : | |
| 10201 :finally | |
| 10202 : let &ts = s:saved_ts | |
| 10203 : unlet s:saved_ts | |
| 10204 :endtry | |
| 10205 | |
| 10206 This method should be used locally whenever a function or part of a script | |
| 10207 changes global settings which need to be restored on failure or normal exit of | |
| 10208 that function or script part. | |
| 10209 | |
| 10210 *break-finally* | |
| 10211 Cleanup code works also when the try block or a catch clause is left by | |
| 10212 a ":continue", ":break", ":return", or ":finish". | |
| 10213 Example: > | |
| 10214 | |
| 10215 :let first = 1 | |
| 10216 :while 1 | |
| 10217 : try | |
| 10218 : if first | |
| 10219 : echo "first" | |
| 10220 : let first = 0 | |
| 10221 : continue | |
| 10222 : else | |
| 10223 : throw "second" | |

| 10231 : echo "still in while" | |
| 10232 :endwhile | |
| 10233 :echo "end" | |
| 10234 | |

10249 extra ":return" in the finally clause. (Above all, this would override the |
| 7 | 10250 return value.) |
| 10251 | |
| 10252 *except-from-finally* | |
| 10253 Using either of ":continue", ":break", ":return", ":finish", or ":throw" in | |
| 10254 a finally clause is possible, but not recommended since it abandons the | |
| 10255 cleanup actions for the try conditional. But, of course, interrupt and error | |
| 10256 exceptions might get raised from a finally clause. | |
| 10257 Example where an error in the finally clause stops an interrupt from | |
| 10258 working correctly: > | |
| 10259 | |
| 10260 :try | |
| 10261 : try | |
| 10262 : echo "Press CTRL-C for interrupt" | |
| 10263 : while 1 | |
| 10264 : endwhile | |
| 10265 : finally | |
| 10266 : unlet novar | |
| 10267 : endtry | |
| 10268 :catch /novar/ | |
| 10269 :endtry | |
| 10270 :echo "Script still running" | |
| 10271 :sleep 1 | |
| 10272 | |
| 10273 If you need to put commands that could fail into a finally clause, you should | |
| 10274 think about catching or ignoring the errors in these commands, see | |
| 10275 |catch-errors| and |ignore-errors|. | |
| 10276 | |
| 10277 | |
| 10278 CATCHING ERRORS *catch-errors* | |
| 10279 | |
| 10280 If you want to catch specific errors, you just have to put the code to be | |
| 10281 watched in a try block and add a catch clause for the error message. The | |
| 10282 presence of the try conditional causes all errors to be converted to an | |
| 10283 exception. No message is displayed and |v:errmsg| is not set then. To find | |
| 10284 the right pattern for the ":catch" command, you have to know how the format of | |
| 10285 the error exception is. | |
| 10286 Error exceptions have the following format: > | |
| 10287 | |
| 10288 Vim({cmdname}):{errmsg} | |
| 10289 or > | |
| 10290 Vim:{errmsg} | |
| 10291 | |
| 10292 {cmdname} is the name of the command that failed; the second form is used when | |

10293 the command name is not known. {errmsg} is the error message usually produced |
| 7 | 10294 when the error occurs outside try conditionals. It always begins with |
| 10295 a capital "E", followed by a two or three-digit error number, a colon, and | |
| 10296 a space. | |
| 10297 | |
| 10298 Examples: | |
| 10299 | |
| 10300 The command > | |
| 10301 :unlet novar | |
| 10302 normally produces the error message > | |
| 10303 E108: No such variable: "novar" | |
| 10304 which is converted inside try conditionals to an exception > | |
| 10305 Vim(unlet):E108: No such variable: "novar" | |
| 10306 | |
| 10307 The command > | |
| 10308 :dwim | |
| 10309 normally produces the error message > | |
| 10310 E492: Not an editor command: dwim | |
| 10311 which is converted inside try conditionals to an exception > | |
| 10312 Vim:E492: Not an editor command: dwim | |
| 10313 | |
| 10314 You can catch all ":unlet" errors by a > | |
| 10315 :catch /^Vim(unlet):/ | |
| 10316 or all errors for misspelled command names by a > | |
| 10317 :catch /^Vim:E492:/ | |
| 10318 | |
| 10319 Some error messages may be produced by different commands: > | |
| 10320 :function nofunc | |
| 10321 and > | |
| 10322 :delfunction nofunc | |
| 10323 both produce the error message > | |
| 10324 E128: Function name must start with a capital: nofunc | |
| 10325 which is converted inside try conditionals to an exception > | |
| 10326 Vim(function):E128: Function name must start with a capital: nofunc | |
| 10327 or > | |
| 10328 Vim(delfunction):E128: Function name must start with a capital: nofunc | |
| 10329 respectively. You can catch the error by its number independently on the | |
| 10330 command that caused it if you use the following pattern: > | |
| 10331 :catch /^Vim(\a\+):E128:/ | |
| 10332 | |
| 10333 Some commands like > | |
| 10334 :let x = novar | |
| 10335 produce multiple error messages, here: > | |
| 10336 E121: Undefined variable: novar | |
| 10337 E15: Invalid expression: novar | |
| 10338 Only the first is used for the exception value, since it is the most specific | |
| 10339 one (see |except-several-errors|). So you can catch it by > | |
| 10340 :catch /^Vim(\a\+):E121:/ | |
| 10341 | |
| 10342 You can catch all errors related to the name "nofunc" by > | |
| 10343 :catch /\<nofunc\>/ | |
| 10344 | |
| 10345 You can catch all Vim errors in the ":write" and ":read" commands by > | |
| 10346 :catch /^Vim(\(write\|read\)):E\d\+:/ | |
| 10347 | |
| 10348 You can catch all Vim errors by the pattern > | |
| 10349 :catch /^Vim\((\a\+)\)\=:E\d\+:/ | |
| 10350 < | |
| 10351 *catch-text* | |
| 10352 NOTE: You should never catch the error message text itself: > | |
| 10353 :catch /No such variable/ | |
| 6647 | 10354 only works in the English locale, but not when the user has selected |
| 7 | 10355 a different language by the |:language| command. It is however helpful to |
| 10356 cite the message text in a comment: > | |
| 10357 :catch /^Vim(\a\+):E108:/ " No such variable | |
| 10358 | |
| 10359 | |
| 10360 IGNORING ERRORS *ignore-errors* | |
| 10361 | |
| 10362 You can ignore errors in a specific Vim command by catching them locally: > | |
| 10363 | |
| 10364 :try | |
| 10365 : write | |
| 10366 :catch | |
| 10367 :endtry | |
| 10368 | |
| 10369 But you are strongly recommended NOT to use this simple form, since it could | |
| 10370 catch more than you want. With the ":write" command, some autocommands could | |
| 10371 be executed and cause errors not related to writing, for instance: > | |
| 10372 | |
| 10373 :au BufWritePre * unlet novar | |
| 10374 | |
| 10375 There could even be such errors you are not responsible for as a script | |
| 10376 writer: a user of your script might have defined such autocommands. You would | |
| 10377 then hide the error from the user. | |
| 10378 It is much better to use > | |
| 10379 | |
| 10380 :try | |
| 10381 : write | |
| 10382 :catch /^Vim(write):/ | |
| 10383 :endtry | |
| 10384 | |
| 10385 which only catches real write errors. So catch only what you'd like to ignore | |
| 10386 intentionally. | |
| 10387 | |
| 10388 For a single command that does not cause execution of autocommands, you could | |
| 10389 even suppress the conversion of errors to exceptions by the ":silent!" | |
| 10390 command: > | |
| 10391 :silent! nunmap k | |
| 10392 This works also when a try conditional is active. | |
| 10393 | |
| 10394 | |

| 7 | 10433 |
| 10434 For testing what happens when CTRL-C would be pressed on a specific line in | |
| 10435 your script, use the debug mode and execute the |>quit| or |>interrupt| | |
| 10436 command on that line. See |debug-scripts|. | |

| 10439 CATCHING ALL *catch-all* | |
| 10440 | |
| 10441 The commands > | |
| 10442 | |
| 10443 :catch /.*/ | |
| 10444 :catch // | |
| 10445 :catch | |
| 10446 | |
| 10447 catch everything, error exceptions, interrupt exceptions and exceptions | |
| 10448 explicitly thrown by the |:throw| command. This is useful at the top level of | |
| 10449 a script in order to catch unexpected things. | |
| 10450 Example: > | |
| 10451 | |
| 10452 :try | |
| 10453 : | |
| 10454 : " do the hard work here | |
| 10455 : | |
| 10456 :catch /MyException/ | |
| 10457 : | |
| 10458 : " handle known problem | |
| 10459 : | |
| 10460 :catch /^Vim:Interrupt$/ | |
| 10461 : echo "Script interrupted" | |
| 10462 :catch /.*/ | |
| 10463 : echo "Internal error (" . v:exception . ")" | |
| 10464 : echo " - occurred at " . v:throwpoint | |
| 10465 :endtry | |
| 10466 :" end of script | |
| 10467 | |
| 10468 Note: Catching all might catch more things than you want. Thus, you are | |
| 10469 strongly encouraged to catch only for problems that you can really handle by | |
| 10470 specifying a pattern argument to the ":catch". | |
| 10471 Example: Catching all could make it nearly impossible to interrupt a script | |
| 10472 by pressing CTRL-C: > | |
| 10473 | |
| 10474 :while 1 | |
| 10475 : try | |
| 10476 : sleep 1 | |
| 10477 : catch | |
| 10478 : endtry | |
| 10479 :endwhile | |
| 10480 | |
| 10481 | |
| 10482 EXCEPTIONS AND AUTOCOMMANDS *except-autocmd* | |
| 10483 | |
| 10484 Exceptions may be used during execution of autocommands. Example: > | |
| 10485 | |
| 10486 :autocmd User x try | |
| 10487 :autocmd User x throw "Oops!" | |
| 10488 :autocmd User x catch | |
| 10489 :autocmd User x echo v:exception | |
| 10490 :autocmd User x endtry | |
| 10491 :autocmd User x throw "Arrgh!" | |
| 10492 :autocmd User x echo "Should not be displayed" | |
| 10493 : | |
| 10494 :try | |
| 10495 : doautocmd User x | |
| 10496 :catch | |
| 10497 : echo v:exception | |
| 10498 :endtry | |
| 10499 | |
| 10500 This displays "Oops!" and "Arrgh!". | |
| 10501 | |
| 10502 *except-autocmd-Pre* | |
| 10503 For some commands, autocommands get executed before the main action of the | |
| 10504 command takes place. If an exception is thrown and not caught in the sequence | |
| 10505 of autocommands, the sequence and the command that caused its execution are | |
| 10506 abandoned and the exception is propagated to the caller of the command. | |
| 10507 Example: > | |
| 10508 | |
| 10509 :autocmd BufWritePre * throw "FAIL" | |
| 10510 :autocmd BufWritePre * echo "Should not be displayed" | |
| 10511 : | |
| 10512 :try | |
| 10513 : write | |
| 10514 :catch | |
| 10515 : echo "Caught:" v:exception "from" v:throwpoint | |
| 10516 :endtry | |
| 10517 | |
| 10518 Here, the ":write" command does not write the file currently being edited (as | |
| 10519 you can see by checking 'modified'), since the exception from the BufWritePre | |
| 10520 autocommand abandons the ":write". The exception is then caught and the | |
| 10521 script displays: > | |
| 10522 | |
| 10523 Caught: FAIL from BufWrite Auto commands for "*" | |
| 10524 < | |
| 10525 *except-autocmd-Post* | |
| 10526 For some commands, autocommands get executed after the main action of the | |
| 10527 command has taken place. If this main action fails and the command is inside | |
| 10528 an active try conditional, the autocommands are skipped and an error exception | |
| 10529 is thrown that can be caught by the caller of the command. | |
| 10530 Example: > | |
| 10531 | |
| 10532 :autocmd BufWritePost * echo "File successfully written!" | |
| 10533 : | |
| 10534 :try | |
| 10535 : write /i/m/p/o/s/s/i/b/l/e | |
| 10536 :catch | |
| 10537 : echo v:exception | |
| 10538 :endtry | |
| 10539 | |
| 10540 This just displays: > | |
| 10541 | |
| 10542 Vim(write):E212: Can't open file for writing (/i/m/p/o/s/s/i/b/l/e) | |
| 10543 | |
| 10544 If you really need to execute the autocommands even when the main action | |
| 10545 fails, trigger the event from the catch clause. | |
| 10546 Example: > | |
| 10547 | |
| 10548 :autocmd BufWritePre * set noreadonly | |
| 10549 :autocmd BufWritePost * set readonly | |
| 10550 : | |
| 10551 :try | |
| 10552 : write /i/m/p/o/s/s/i/b/l/e | |
| 10553 :catch | |
| 10554 : doautocmd BufWritePost /i/m/p/o/s/s/i/b/l/e | |
| 10555 :endtry | |
| 10556 < | |
| 10557 You can also use ":silent!": > | |
| 10558 | |
| 10559 :let x = "ok" | |
| 10560 :let v:errmsg = "" | |
| 10561 :autocmd BufWritePost * if v:errmsg != "" | |
| 10562 :autocmd BufWritePost * let x = "after fail" | |
| 10563 :autocmd BufWritePost * endif | |
| 10564 :try | |
| 10565 : silent! write /i/m/p/o/s/s/i/b/l/e | |
| 10566 :catch | |
| 10567 :endtry | |
| 10568 :echo x | |
| 10569 | |
| 10570 This displays "after fail". | |
| 10571 | |
| 10572 If the main action of the command does not fail, exceptions from the | |
| 10573 autocommands will be catchable by the caller of the command: > | |
| 10574 | |
| 10575 :autocmd BufWritePost * throw ":-(" | |
| 10576 :autocmd BufWritePost * echo "Should not be displayed" | |
| 10577 : | |
| 10578 :try | |
| 10579 : write | |
| 10580 :catch | |
| 10581 : echo v:exception | |
| 10582 :endtry | |
| 10583 < | |
| 10584 *except-autocmd-Cmd* | |
| 10585 For some commands, the normal action can be replaced by a sequence of | |
| 10586 autocommands. Exceptions from that sequence will be catchable by the caller | |
| 10587 of the command. | |
| 10588 Example: For the ":write" command, the caller cannot know whether the file | |

| 10633 :autocmd BufWritePre * try | |
| 10634 : | |

| 10640 | |
| 10641 | |
| 10642 EXCEPTION HIERARCHIES AND PARAMETERIZED EXCEPTIONS *except-hier-param* | |
| 10643 | |
| 10644 Some programming languages allow to use hierarchies of exception classes or to | |
| 10645 pass additional information with the object of an exception class. You can do | |
| 10646 similar things in Vim. | |
| 10647 In order to throw an exception from a hierarchy, just throw the complete | |
| 10648 class name with the components separated by a colon, for instance throw the | |
| 10649 string "EXCEPT:MATHERR:OVERFLOW" for an overflow in a mathematical library. | |
| 10650 When you want to pass additional information with your exception class, add | |
| 10651 it in parentheses, for instance throw the string "EXCEPT:IO:WRITEERR(myfile)" | |
| 10652 for an error when writing "myfile". | |
| 10653 With the appropriate patterns in the ":catch" command, you can catch for | |
| 10654 base classes or derived classes of your hierarchy. Additional information in | |
| 10655 parentheses can be cut out from |v:exception| with the ":substitute" command. | |
| 10656 Example: > | |
| 10657 | |
| 10658 :function! CheckRange(a, func) | |
| 10659 : if a:a < 0 | |
| 10660 : throw "EXCEPT:MATHERR:RANGE(" . a:func . ")" | |
| 10661 : endif | |
| 10662 :endfunction | |
| 10663 : | |
| 10664 :function! Add(a, b) | |
| 10665 : call CheckRange(a:a, "Add") | |
| 10666 : call CheckRange(a:b, "Add") | |
| 10667 : let c = a:a + a:b | |
| 10668 : if c < 0 | |
| 10669 : throw "EXCEPT:MATHERR:OVERFLOW" | |
| 10670 : endif | |
| 10671 : return c | |
| 10672 :endfunction | |
| 10673 : | |
| 10674 :function! Div(a, b) | |
| 10675 : call CheckRange(a:a, "Div") | |
| 10676 : call CheckRange(a:b, "Div") | |
| 10677 : if (a:b == 0) | |
| 10678 : throw "EXCEPT:MATHERR:ZERODIV" | |

| 10710 :catch /^EXCEPT/ | |
| 10711 : echo "Unspecified error" | |
| 10712 : | |
| 10713 :endtry | |
| 10714 | |
| 10715 The exceptions raised by Vim itself (on error or when pressing CTRL-C) use | |
| 10716 a flat hierarchy: they are all in the "Vim" class. You cannot throw yourself | |
| 10717 exceptions with the "Vim" prefix; they are reserved for Vim. | |
| 10718 Vim error exceptions are parameterized with the name of the command that | |
| 10719 failed, if known. See |catch-errors|. | |
| 10720 | |
| 10721 | |
| 10722 PECULIARITIES | |
| 10723 *except-compat* | |
| 10724 The exception handling concept requires that the command sequence causing the | |
| 10725 exception is aborted immediately and control is transferred to finally clauses | |
| 10726 and/or a catch clause. | |
| 10727 | |
| 10728 In the Vim script language there are cases where scripts and functions | |
| 10729 continue after an error: in functions without the "abort" flag or in a command | |
| 10730 after ":silent!", control flow goes to the following line, and outside | |
| 10731 functions, control flow goes to the line following the outermost ":endwhile" | |
| 10732 or ":endif". On the other hand, errors should be catchable as exceptions | |
| 10733 (thus, requiring the immediate abortion). | |
| 10734 | |
| 10735 This problem has been solved by converting errors to exceptions and using | |
| 10736 immediate abortion (if not suppressed by ":silent!") only when a try | |

10738 be caught only from an active try conditional. If you want an immediate |
| 7 | 10739 termination without catching the error, just use a try conditional without |
| 10740 catch clause. (You can cause cleanup code being executed before termination | |
| 10741 by specifying a finally clause.) | |
| 10742 | |
| 10743 When no try conditional is active, the usual abortion and continuation | |
| 10744 behavior is used instead of immediate abortion. This ensures compatibility of | |
| 10745 scripts written for Vim 6.1 and earlier. | |
| 10746 | |
| 10747 However, when sourcing an existing script that does not use exception handling | |
| 10748 commands (or when calling one of its functions) from inside an active try | |
| 10749 conditional of a new script, you might change the control flow of the existing | |
| 10750 script on error. You get the immediate abortion on error and can catch the | |
| 10751 error in the new script. If however the sourced script suppresses error | |
| 10752 messages by using the ":silent!" command (checking for errors by testing | |

10754 not converted to an exception. (See |:silent|.) So the only remaining cause |
| 7 | 10755 where this happens is for scripts that don't care about errors and produce |
| 10756 error messages. You probably won't want to use such code from your new | |
| 10757 scripts. | |
| 10758 | |
| 10759 *except-syntax-err* | |
| 10760 Syntax errors in the exception handling commands are never caught by any of | |
| 10761 the ":catch" commands of the try conditional they belong to. Its finally | |
| 10762 clauses, however, is executed. | |
| 10763 Example: > | |
| 10764 | |
| 10765 :try | |
| 10766 : try | |
| 10767 : throw 4711 | |
| 10768 : catch /\(/ | |
| 10769 : echo "in catch with syntax error" | |
| 10770 : catch | |
| 10771 : echo "inner catch-all" | |
| 10772 : finally | |
| 10773 : echo "inner finally" | |
| 10774 : endtry | |
| 10775 :catch | |
| 10776 : echo 'outer catch-all caught "' . v:exception . '"' | |
| 10777 : finally | |
| 10778 : echo "outer finally" | |
| 10779 :endtry | |
| 10780 | |
| 10781 This displays: > | |
| 10782 inner finally | |
| 10783 outer catch-all caught "Vim(catch):E54: Unmatched \(" | |
| 10784 outer finally | |
| 10785 The original exception is discarded and an error exception is raised, instead. | |
| 10786 | |
| 10787 *except-single-line* | |
| 10788 The ":try", ":catch", ":finally", and ":endtry" commands can be put on | |
| 10789 a single line, but then syntax errors may make it difficult to recognize the | |
| 10790 "catch" line, thus you better avoid this. | |
| 10791 Example: > | |
| 10792 :try | unlet! foo # | catch | endtry | |
| 10793 raises an error exception for the trailing characters after the ":unlet!" | |
| 10794 argument, but does not see the ":catch" and ":endtry" commands, so that the | |
| 10795 error exception is discarded and the "E488: Trailing characters" message gets | |
| 10796 displayed. | |
| 10797 | |
| 10798 *except-several-errors* | |
| 10799 When several errors appear in a single command, the first error message is | |
| 10800 usually the most specific one and therefor converted to the error exception. | |
| 10801 Example: > | |
| 10802 echo novar | |
| 10803 causes > | |
| 10804 E121: Undefined variable: novar | |
| 10805 E15: Invalid expression: novar | |
| 10806 The value of the error exception inside try conditionals is: > | |
| 10807 Vim(echo):E121: Undefined variable: novar | |
| 10808 < *except-syntax-error* | |
| 10809 But when a syntax error is detected after a normal error in the same command, | |
| 10810 the syntax error is used for the exception being thrown. | |
| 10811 Example: > | |
| 10812 unlet novar # | |
| 10813 causes > | |
| 10814 E108: No such variable: "novar" | |
| 10815 E488: Trailing characters | |
| 10816 The value of the error exception inside try conditionals is: > | |
| 10817 Vim(unlet):E488: Trailing characters | |
| 10818 This is done because the syntax error might change the execution path in a way | |
| 10819 not intended by the user. Example: > | |
| 10820 try | |
| 10821 try | unlet novar # | catch | echo v:exception | endtry | |
| 10822 catch /.*/ | |
| 10823 echo "outer catch:" v:exception | |
| 10824 endtry | |
| 10825 This displays "outer catch: Vim(unlet):E488: Trailing characters", and then | |
| 10826 a "E600: Missing :endtry" error message is given, see |except-single-line|. | |

| 10862 | |
| 10863 This example sorts lines with a specific compare function. > | |
| 10864 | |
| 10865 :func SortBuffer() | |
| 10866 : let lines = getline(1, '$') | |
| 10867 : call sort(lines, function("Strcmp")) | |

| 10873 | |
| 10874 | |
| 10875 scanf() replacement ~ | |
| 7 | 10876 *sscanf* |
| 10877 There is no sscanf() function in Vim. If you need to extract parts from a | |
| 10878 line, you can use matchstr() and substitute() to do it. This example shows | |
| 10879 how to get the file name, line number and column number out of a line like | |
| 10880 "foobar.txt, 123, 45". > | |
| 10881 :" Set up the match bit | |
| 10882 :let mx='\(\f\+\),\s*\(\d\+\),\s*\(\d\+\)' | |
| 10883 :"get the part matching the whole expression | |
| 10884 :let l = matchstr(line, mx) | |
| 10885 :"get each item out of the match | |
| 10886 :let file = substitute(l, mx, '\1', '') | |
| 10887 :let lnum = substitute(l, mx, '\2', '') | |
| 10888 :let col = substitute(l, mx, '\3', '') | |
| 10889 | |
| 10890 The input is in the variable "line", the results in the variables "file", | |
| 10891 "lnum" and "col". (idea from Michael Geddes) | |
| 10892 | |
| 1156 | 10893 |
| 10894 getting the scriptnames in a Dictionary ~ | |
| 10895 *scriptnames-dictionary* | |
| 10896 The |:scriptnames| command can be used to get a list of all script files that | |
| 10897 have been sourced. There is no equivalent function or variable for this | |
| 10898 (because it's rarely needed). In case you need to manipulate the list this | |
| 10899 code can be used: > | |
| 10900 " Get the output of ":scriptnames" in the scriptnames_output variable. | |
| 10901 let scriptnames_output = '' | |
| 10902 redir => scriptnames_output | |
| 10903 silent scriptnames | |
| 10904 redir END | |
| 10905 | |
| 1621 | 10906 " Split the output into lines and parse each line. Add an entry to the |
| 1156 | 10907 " "scripts" dictionary. |
| 10908 let scripts = {} | |
| 10909 for line in split(scriptnames_output, "\n") | |
| 10910 " Only do non-blank lines. | |
| 10911 if line =~ '\S' | |
| 10912 " Get the first number in the line. | |
| 1621 | 10913 let nr = matchstr(line, '\d\+') |
| 1156 | 10914 " Get the file name, remove the script number " 123: ". |
| 1621 | 10915 let name = substitute(line, '.\+:\s*', '', '') |
| 1156 | 10916 " Add an item to the Dictionary |
| 1621 | 10917 let scripts[nr] = name |
| 1156 | 10918 endif |
| 10919 endfor | |
| 10920 unlet scriptnames_output | |

| 10923 10. No +eval feature *no-eval-feature* | |
| 10924 | |
| 10925 When the |+eval| feature was disabled at compile time, none of the expression | |
| 10926 evaluation commands are available. To prevent this from causing Vim scripts | |
| 10927 to generate all kinds of errors, the ":if" and ":endif" commands are still | |
| 10928 recognized, though the argument of the ":if" and everything between the ":if" | |
| 10929 and the matching ":endif" is ignored. Nesting of ":if" blocks is allowed, but | |
| 10930 only if the commands are at the start of the line. The ":else" command is not | |
| 10931 recognized. | |
| 10932 | |
| 10933 Example of how to avoid executing commands when the |+eval| feature is | |
| 10934 missing: > | |
| 10935 | |
| 10936 :if 1 | |
| 10937 : echo "Expression evaluation is compiled in" | |
| 10938 :else | |
| 10939 : echo "You will _never_ see this message" | |
| 10940 :endif | |
| 10941 | |
| 11347 | 10942 To execute a command only when the |+eval| feature is disabled requires a trick, |
| 10943 as this example shows: > | |

10960 the command from a tags file is executed and for CTRL-R = in the command line. |
| 29 | 10961 The sandbox is also used for the |:sandbox| command. |
| 7 | 10962 |
| 10963 These items are not allowed in the sandbox: | |
| 10964 - changing the buffer text | |
| 10965 - defining or changing mapping, autocommands, functions, user commands | |
| 10966 - setting certain options (see |option-summary|) | |
| 1156 | 10967 - setting certain v: variables (see |v:var|) *E794* |
| 7 | 10968 - executing a shell command |
| 10969 - reading or writing a file | |
| 10970 - jumping to another buffer or editing a file | |
| 625 | 10971 - executing Python, Perl, etc. commands |
| 29 | 10972 This is not guaranteed 100% secure, but it should block most attacks. |
| 10973 | |
| 10974 *:san* *:sandbox* | |
| 401 | 10975 :san[dbox] {cmd} Execute {cmd} in the sandbox. Useful to evaluate an |
| 29 | 10976 option that may have been set from a modeline, e.g. |
| 10977 'foldexpr'. | |
| 10978 | |
| 634 | 10979 *sandbox-option* |
| 10980 A few options contain an expression. When this expression is evaluated it may | |
| 790 | 10981 have to be done in the sandbox to avoid a security risk. But the sandbox is |
| 634 | 10982 restrictive, thus this only happens when the option was set from an insecure |
| 10983 location. Insecure in this context are: | |
| 843 | 10984 - sourcing a .vimrc or .exrc in the current directory |
| 634 | 10985 - while executing in the sandbox |
| 10986 - value coming from a modeline | |
| 10987 | |
| 10988 Note that when in the sandbox and saving an option value and restoring it, the | |
| 10989 option will still be marked as it was set in the sandbox. | |

| 10992 12. Textlock *textlock* | |
| 10993 | |
| 10994 In a few situations it is not allowed to change the text in the buffer, jump | |
| 10995 to another window and some other things that might confuse or break what Vim | |
| 10996 is currently doing. This mostly applies to things that happen when Vim is | |

10997 actually doing something else. For example, evaluating the 'balloonexpr' may |
| 634 | 10998 happen any moment the mouse cursor is resting at some position. |
| 10999 | |
| 11000 This is not allowed when the textlock is active: | |
| 11001 - changing the buffer text | |
| 11002 - jumping to another buffer or window | |
| 11003 - editing another file | |
| 11004 - closing a window or quitting Vim | |
