| 21 ============================================================================== | |
| 22 1. Introduction *edit-intro* | |
| 23 | |
| 24 Editing a file with Vim means: | |
| 25 | |
| 39 | 26 1. reading the file into a buffer |
| 7 | 27 2. changing the buffer with editor commands |
| 28 3. writing the buffer into a file | |
| 29 | |
| 30 *current-file* | |
| 31 As long as you don't write the buffer, the original file remains unchanged. | |
| 32 If you start editing a file (read a file into the buffer), the file name is | |
| 22 | 33 remembered as the "current file name". This is also known as the name of the |
| 39 | 34 current buffer. It can be used with "%" on the command line |:_%|. |
| 7 | 35 |
| 36 *alternate-file* | |
| 37 If there already was a current file name, then that one becomes the alternate | |
| 39 | 38 file name. It can be used with "#" on the command line |:_#| and you can use |
| 39 the |CTRL-^| command to toggle between the current and the alternate file. | |
| 40 However, the alternate file name is not changed when |:keepalt| is used. | |
| 5510 | 41 An alternate file name is remembered for each window. |
| 22 | 42 |
| 43 *:keepalt* *:keepa* | |
| 44 :keepalt {cmd} Execute {cmd} while keeping the current alternate file | |
| 45 name. Note that commands invoked indirectly (e.g., | |
| 46 with a function) may still set the alternate file | |

47 name. |
| 22 | 48 |
| 39 | 49 All file names are remembered in the buffer list. When you enter a file name, |
| 236 | 50 for editing (e.g., with ":e filename") or writing (e.g., with ":w filename"), |
| 39 | 51 the file name is added to the list. You can use the buffer list to remember |
| 52 which files you edited and to quickly switch from one file to another (e.g., | |
| 53 to copy text) with the |CTRL-^| command. First type the number of the file | |
| 16610 | 54 and then hit CTRL-^. |
| 39 | 55 |
| 7 | 56 |
| 57 CTRL-G or *CTRL-G* *:f* *:fi* *:file* | |
| 268 | 58 :f[ile] Prints the current file name (as typed, unless ":cd" |
| 59 was used), the cursor position (unless the 'ruler' | |
| 60 option is set), and the file status (readonly, | |
| 61 modified, read errors, new file). See the 'shortmess' | |
| 62 option about how to make this message shorter. | |
| 7 | 63 |
| 14 | 64 :f[ile]! like |:file|, but don't truncate the name even when |
| 65 'shortmess' indicates this. | |
| 66 | |
| 7 | 67 {count}CTRL-G Like CTRL-G, but prints the current file name with |
| 68 full path. If the count is higher than 1 the current | |

69 buffer number is also given. |

| 71 *g_CTRL-G* *word-count* *byte-count* | |
| 161 | 72 g CTRL-G Prints the current position of the cursor in five |
| 73 ways: Column, Line, Word, Character and Byte. If the | |
| 74 number of Characters and Bytes is the same then the | |
| 75 Character position is omitted. | |
| 22723 | 76 |
| 161 | 77 If there are characters in the line that take more |
| 78 than one position on the screen (<Tab> or special | |
| 22723 | 79 character), or characters using more than one byte per |
| 80 column (characters above 0x7F when 'encoding' is | |
| 81 utf-8), both the byte column and the screen column are | |
| 82 shown, separated by a dash. | |

| 104 :buffers | |
| 105 :files | |
| 106 :ls List all the currently known file names. See | |
| 18016 | 107 |windows.txt| |:files| |:buffers| |:ls|. |
| 7 | 108 |
| 109 Vim will remember the full path name of a file name that you enter. In most | |
| 110 cases when the file name is displayed only the name you typed is shown, but | |
| 111 the full path name is being used if you used the ":cd" command |:cd|. | |
| 112 | |
| 113 *home-replace* | |
| 114 If the environment variable $HOME is set, and the file name starts with that | |
| 115 string, it is often displayed with HOME replaced with "~". This was done to | |
| 116 keep file names short. When reading or writing files the full name is still | |
| 117 used, the "~" is only used when displaying file names. When replacing the | |
| 118 file name would result in just "~", "~/" is used instead (to avoid confusion | |
| 42 | 119 between options set to $HOME with 'backupext' set to "~"). |
| 7 | 120 |
| 121 When writing the buffer, the default is to use the current file name. Thus | |
| 122 when you give the "ZZ" or ":wq" command, the original file will be | |
| 123 overwritten. If you do not want this, the buffer can be written into another | |
| 124 file by giving a file name argument to the ":write" command. For example: > | |
| 125 | |
| 126 vim testfile | |
| 127 [change the buffer with editor commands] | |
| 128 :w newfile | |
| 129 :q | |
| 130 | |
| 131 This will create a file "newfile", that is a modified copy of "testfile". | |
| 132 The file "testfile" will remain unchanged. Anyway, if the 'backup' option is | |
| 133 set, Vim renames or copies the original file before it will be overwritten. | |
| 134 You can use this file if you discover that you need the original file. See | |
| 135 also the 'patchmode' option. The name of the backup file is normally the same | |
| 136 as the original file with 'backupext' appended. The default "~" is a bit | |
| 137 strange to avoid accidentally overwriting existing files. If you prefer ".bak" | |
| 18972 | 138 change the 'backupext' option. Extra dots are replaced with '_' on MS-Windows |
| 7 | 139 machines, when Vim has detected that an MS-DOS-like filesystem is being used |
| 140 (e.g., messydos or crossdos) or when the 'shortname' option is on. The | |
| 141 backup file can be placed in another directory by setting 'backupdir'. | |
| 142 | |
| 143 *auto-shortname* | |
| 144 Technical: On the Amiga you can use 30 characters for a file name. But on an | |
| 145 MS-DOS-compatible filesystem only 8 plus 3 characters are | |
| 146 available. Vim tries to detect the type of filesystem when it is | |
| 147 creating the .swp file. If an MS-DOS-like filesystem is suspected, | |
| 148 a flag is set that has the same effect as setting the 'shortname' | |
| 149 option. This flag will be reset as soon as you start editing a | |
| 150 new file. The flag will be used when making the file name for the | |
| 151 ".swp" and ".~" files for the current file. But when you are | |
| 152 editing a file in a normal filesystem and write to an MS-DOS-like | |
| 153 filesystem the flag will not have been set. In that case the | |
| 154 creation of the ".~" file may fail and you will get an error | |
| 155 message. Use the 'shortname' option in this case. | |
| 156 | |
| 157 When you started editing without giving a file name, "No File" is displayed in | |
| 158 messages. If the ":write" command is used with a file name argument, the file | |
| 159 name for the current file is set to that file name. This only happens when | |
| 633 | 160 the 'F' flag is included in 'cpoptions' (by default it is included) |cpo-F|. |
| 161 This is useful when entering text in an empty buffer and then writing it to a | |
| 162 file. If 'cpoptions' contains the 'f' flag (by default it is NOT included) | |
| 163 |cpo-f| the file name is set for the ":read file" command. This is useful | |
| 164 when starting Vim without an argument and then doing ":read file" to start | |
| 165 editing a file. | |
| 166 When the file name was set and 'filetype' is empty the filetype detection | |
| 167 autocommands will be triggered. | |
| 7 | 168 *not-edited* |
| 169 Because the file name was set without really starting to edit that file, you | |
| 170 are protected from overwriting that file. This is done by setting the | |
| 171 "notedited" flag. You can see if this flag is set with the CTRL-G or ":file" | |
| 172 command. It will include "[Not edited]" when the "notedited" flag is set. | |
| 173 When writing the buffer to the current file name (with ":w!"), the "notedited" | |
| 174 flag is reset. | |
| 175 | |
| 176 *abandon* | |
| 177 Vim remembers whether you have changed the buffer. You are protected from | |
| 178 losing the changes you made. If you try to quit without writing, or want to | |
| 179 start editing another file, Vim will refuse this. In order to overrule this | |
| 180 protection, add a '!' to the command. The changes will then be lost. For | |
| 181 example: ":q" will not work if the buffer was changed, but ":q!" will. To see | |
| 182 whether the buffer was changed use the "CTRL-G" command. The message includes | |

184 is in 'shortmess'. |
| 7 | 185 |
| 186 If you want to automatically save the changes without asking, switch on the | |
| 187 'autowriteall' option. 'autowrite' is the associated Vi-compatible option | |
| 188 that does not work for all commands. | |
| 189 | |
| 190 If you want to keep the changed buffer without saving it, switch on the | |
| 5277 | 191 'hidden' option. See |hidden-buffer|. Some commands work like this even when |
| 192 'hidden' is not set, check the help for the command. | |
| 7 | 193 |
| 194 ============================================================================== | |
| 195 2. Editing a file *edit-a-file* | |
| 196 | |
| 5277 | 197 *:e* *:edit* *reload* |
| 7 | 198 :e[dit] [++opt] [+cmd] Edit the current file. This is useful to re-edit the |
| 199 current file, when it has been changed outside of Vim. | |
| 200 This fails when changes have been made to the current | |
| 201 buffer and 'autowriteall' isn't set or the file can't | |
| 202 be written. | |
| 203 Also see |++opt| and |+cmd|. | |
| 204 | |
| 5277 | 205 *:edit!* *discard* |
| 7 | 206 :e[dit]! [++opt] [+cmd] |
| 207 Edit the current file always. Discard any changes to | |
| 208 the current buffer. This is useful if you want to | |
| 209 start all over again. | |
| 210 Also see |++opt| and |+cmd|. | |
| 211 | |
| 212 *:edit_f* | |
| 213 :e[dit] [++opt] [+cmd] {file} | |
| 214 Edit {file}. | |
| 215 This fails when changes have been made to the current | |
| 216 buffer, unless 'hidden' is set or 'autowriteall' is | |
| 217 set and the file can be written. | |
| 218 Also see |++opt| and |+cmd|. | |
| 219 | |
| 220 *:edit!_f* | |
| 221 :e[dit]! [++opt] [+cmd] {file} | |
| 222 Edit {file} always. Discard any changes to the | |
| 223 current buffer. | |
| 224 Also see |++opt| and |+cmd|. | |
| 27804 | 225 *:edit_#* *:e#* |
| 7 | 226 :e[dit] [++opt] [+cmd] #[count] |
| 39 | 227 Edit the [count]th buffer (as shown by |:files|). |
| 228 This command does the same as [count] CTRL-^. But ":e | |
| 229 #" doesn't work if the alternate buffer doesn't have a | |
| 230 file name, while CTRL-^ still works then. | |
| 7 | 231 Also see |++opt| and |+cmd|. |
| 232 | |
| 233 *:ene* *:enew* | |
| 234 :ene[w] Edit a new, unnamed buffer. This fails when changes | |
| 235 have been made to the current buffer, unless 'hidden' | |
| 236 is set or 'autowriteall' is set and the file can be | |
| 237 written. | |
| 238 If 'fileformats' is not empty, the first format given | |
| 239 will be used for the new buffer. If 'fileformats' is | |
| 240 empty, the 'fileformat' of the current buffer is used. | |
| 241 | |
| 242 *:ene!* *:enew!* | |
| 243 :ene[w]! Edit a new, unnamed buffer. Discard any changes to | |
| 244 the current buffer. | |
| 245 Set 'fileformat' like |:enew|. | |
| 246 | |
| 247 *:fin* *:find* | |
| 248 :fin[d][!] [++opt] [+cmd] {file} | |
| 249 Find {file} in 'path' and then |:edit| it. | |
| 250 | |
| 251 :{count}fin[d][!] [++opt] [+cmd] {file} | |
| 252 Just like ":find", but use the {count} match in | |
| 253 'path'. Thus ":2find file" will find the second | |
| 254 "file" found in 'path'. When there are fewer matches | |
| 255 for the file in 'path' than asked for, you get an | |
| 256 error message. | |
| 257 | |
| 258 *:ex* | |
| 259 :ex [++opt] [+cmd] [file] | |
| 260 Same as |:edit|. | |
| 261 | |
| 262 *:vi* *:visual* | |
| 263 :vi[sual][!] [++opt] [+cmd] [file] | |
| 42 | 264 When used in Ex mode: Leave |Ex-mode|, go back to |

271 'readonly' option for this buffer. |
| 7 | 272 |
| 273 *CTRL-^* *CTRL-6* | |
| 2725 | 274 CTRL-^ Edit the alternate file. Mostly the alternate file is |
| 275 the previously edited file. This is a quick way to | |
| 276 toggle between two files. It is equivalent to ":e #", | |
| 277 except that it also works when there is no file name. | |
| 278 | |
| 7 | 279 If the 'autowrite' or 'autowriteall' option is on and |
| 280 the buffer was changed, write it. | |
| 281 Mostly the ^ character is positioned on the 6 key, | |
| 282 pressing CTRL and 6 then gets you what we call CTRL-^. | |
| 283 But on some non-US keyboards CTRL-^ is produced in | |
| 284 another way. | |
| 285 | |
| 39 | 286 {count}CTRL-^ Edit [count]th file in the buffer list (equivalent to |
| 287 ":e #[count]"). This is a quick way to switch between | |
| 288 files. | |
| 289 See |CTRL-^| above for further details. | |
| 290 | |
| 7 | 291 [count]]f *]f* *[f* |
| 292 [count][f Same as "gf". Deprecated. | |
| 293 | |
| 294 *gf* *E446* *E447* | |
| 295 [count]gf Edit the file whose name is under or after the cursor. | |
| 296 Mnemonic: "goto file". | |
| 297 Uses the 'isfname' option to find out which characters | |
| 298 are supposed to be in a file name. Trailing | |
| 6647 | 299 punctuation characters ".,:;!" are ignored. Escaped |
| 300 spaces "\ " are reduced to a single space. | |
| 1668 | 301 Uses the 'path' option as a list of directory names to |
| 302 look for the file. See the 'path' option for details | |
| 303 about relative directories and wildcards. | |
| 7 | 304 Uses the 'suffixesadd' option to check for file names |
| 305 with a suffix added. | |
| 306 If the file can't be found, 'includeexpr' is used to | |
| 307 modify the name and another attempt is done. | |
| 308 If a [count] is given, the count'th file that is found | |
| 309 in the 'path' is edited. | |
| 310 This command fails if Vim refuses to |abandon| the | |
| 311 current file. | |
| 820 | 312 If you want to edit the file in a new window use |
| 313 |CTRL-W_CTRL-F|. | |
| 7 | 314 If you do want to edit a new file, use: > |
| 315 :e <cfile> | |
| 316 < To make gf always work like that: > | |
| 317 :map gf :e <cfile><CR> | |
| 318 < If the name is a hypertext link, that looks like | |
| 319 "type://machine/path", you need the |netrw| plugin. | |
| 320 For Unix the '~' character is expanded, like in | |
| 321 "~user/file". Environment variables are expanded too | |
| 322 |expand-env|. | |
| 323 | |
| 324 *v_gf* | |
| 325 {Visual}[count]gf Same as "gf", but the highlighted text is used as the | |
| 326 name of the file to edit. 'isfname' is ignored. | |
| 327 Leading blanks are skipped, otherwise all blanks and | |
| 328 special characters are included in the file name. | |
| 329 (For {Visual} see |Visual-mode|.) | |
| 330 | |
| 681 | 331 *gF* |
| 332 [count]gF Same as "gf", except if a number follows the file | |
| 333 name, then the cursor is positioned on that line in | |
| 18972 | 334 the file. |
| 335 The file name and the number must be separated by a | |
| 336 non-filename (see 'isfname') and non-numeric | |
| 337 character. " line " is also recognized, like it is | |
| 338 used in the output of `:verbose command UserCmd` | |
| 339 White space between the filename, the separator and | |
| 340 the number are ignored. | |
| 852 | 341 Examples: |
| 342 eval.c:10 ~ | |
| 343 eval.c @ 20 ~ | |
| 344 eval.c (30) ~ | |
| 345 eval.c 40 ~ | |
| 346 | |
| 681 | 347 *v_gF* |
| 348 {Visual}[count]gF Same as "v_gf". | |
| 349 | |
| 7 | 350 These commands are used to start editing a single file. This means that the |
| 351 file is read into the buffer and the current file name is set. The file that | |
| 352 is opened depends on the current directory, see |:cd|. | |
| 353 | |
| 354 See |read-messages| for an explanation of the message that is given after the | |
| 355 file has been read. | |
| 356 | |
| 357 You can use the ":e!" command if you messed up the buffer and want to start | |
| 358 all over again. The ":e" command is only useful if you have changed the | |
| 359 current file name. | |
| 360 | |
| 361 *:filename* *{file}* | |
| 1620 | 362 Besides the things mentioned here, more special items for where a filename is |
| 363 expected are mentioned at |cmdline-special|. | |
| 364 | |
| 1668 | 365 Note for systems other than Unix: When using a command that accepts a single |
| 366 file name (like ":edit file") spaces in the file name are allowed, but | |
| 367 trailing spaces are ignored. This is useful on systems that regularly embed | |
| 368 spaces in file names (like MS-Windows and the Amiga). Example: The command | |
| 369 ":e Long File Name " will edit the file "Long File Name". When using a | |
| 370 command that accepts more than one file name (like ":next file1 file2") | |
| 371 embedded spaces must be escaped with a backslash. | |
| 7 | 372 |
| 1121 | 373 *wildcard* *wildcards* |
| 3682 | 374 Wildcards in {file} are expanded, but as with file completion, 'wildignore' |
| 375 and 'suffixes' apply. Which wildcards are supported depends on the system. | |
| 376 These are the common ones: | |
| 444 | 377 ? matches one character |
| 7 | 378 * matches anything, including nothing |
| 444 | 379 ** matches anything, including nothing, recurses into directories |
| 7 | 380 [abc] match 'a', 'b' or 'c' |
| 444 | 381 |
| 7 | 382 To avoid the special meaning of the wildcards prepend a backslash. However, |
| 383 on MS-Windows the backslash is a path separator and "path\[abc]" is still seen | |
| 384 as a wildcard when "[" is in the 'isfname' option. A simple way to avoid this | |

| 7 | 410 *backtick-expansion* *`-expansion* |
| 7013 | 411 On Unix and a few other systems you can also use backticks for the file name |
| 412 argument, for example: > | |
| 413 :next `find . -name ver\\*.c -print` | |

414 :view `ls -t *.patch \| head -n1` |
| 13563 | 415 Vim will run the command in backticks using the 'shell' and use the standard |
| 416 output as argument for the given Vim command (error messages from the shell | |
| 417 command will be discarded). | |
| 418 To see what shell command Vim is running, set the 'verbose' option to 4. When | |
| 419 the shell command returns a non-zero exit code, an error message will be | |
| 420 displayed and the Vim command will be aborted. To avoid this make the shell | |
| 421 always return zero like so: > | |
| 422 :next `find . -name ver\\*.c -print \|\| true` | |
| 423 | |
| 7013 | 424 The backslashes before the star are required to prevent the shell from |
| 425 expanding "ver*.c" prior to execution of the find program. The backslash | |
| 426 before the shell pipe symbol "|" prevents Vim from parsing it as command | |
| 427 termination. | |
| 7 | 428 This also works for most other systems, with the restriction that the |
| 429 backticks must be around the whole item. It is not possible to have text | |
| 430 directly before the first or just after the last backtick. | |
| 431 | |
| 27321 | 432 *`=* *E1083* |
| 7013 | 433 You can have the backticks expanded as a Vim expression, instead of as an |
| 434 external command, by putting an equal sign right after the first backtick, | |
| 435 e.g.: > | |
| 39 | 436 :e `=tempname()` |
| 437 The expression can contain just about anything, thus this can also be used to | |
| 3682 | 438 avoid the special meaning of '"', '|', '%' and '#'. However, 'wildignore' |
| 4119 | 439 does apply like to other wildcards. |

442 expression, thus this works: > |
| 27903 | 443 :e `=$HOME .. '/.vimrc'` |
| 28517 | 444 This uses $HOME inside a string and it will be used literally, most likely not |

| 27903 | 446 :e `='$HOME' .. '/.vimrc'` |
| 7013 | 447 |
| 3682 | 448 If the expression returns a string then names are to be separated with line |
| 449 breaks. When the result is a |List| then each item is used as a name. Line | |
| 450 breaks also separate names. | |

452 expected as an argument to an Ex-command. |
| 7 | 453 |
| 454 *++opt* *[++opt]* | |
| 595 | 455 The [++opt] argument can be used to force the value of 'fileformat', |
| 456 'fileencoding' or 'binary' to a value for one command, and to specify the | |
| 457 behavior for bad characters. The form is: > | |
| 819 | 458 ++{optname} |
| 459 Or: > | |
| 7 | 460 ++{optname}={value} |
| 461 | |
| 819 | 462 Where {optname} is one of: *++ff* *++enc* *++bin* *++nobin* *++edit* |
| 7 | 463 ff or fileformat overrides 'fileformat' |
| 464 enc or encoding overrides 'fileencoding' | |
| 465 bin or binary sets 'binary' | |
| 466 nobin or nobinary resets 'binary' | |
| 856 | 467 bad specifies behavior for bad characters |
| 819 | 468 edit for |:read| only: keep option values as if editing |
| 856 | 469 a file |
| 7 | 470 |
| 471 {value} cannot contain white space. It can be any valid value for these | |
| 472 options. Examples: > | |
| 473 :e ++ff=unix | |
| 474 This edits the same file again with 'fileformat' set to "unix". > | |
| 475 | |
| 476 :w ++enc=latin1 newfile | |
| 477 This writes the current buffer to "newfile" in latin1 format. | |
| 478 | |
| 20379 | 479 The message given when writing a file will show "[converted]" when |
| 480 'fileencoding' or the value specified with ++enc differs from 'encoding'. | |
| 481 | |
| 595 | 482 There may be several ++opt arguments, separated by white space. They must all |
| 483 appear before any |+cmd| argument. | |
| 484 | |
| 485 *++bad* | |
| 486 The argument of "++bad=" specifies what happens with characters that can't be | |
| 487 converted and illegal bytes. It can be one of three things: | |
| 488 ++bad=X A single-byte character that replaces each bad character. | |
| 489 ++bad=keep Keep bad characters without conversion. Note that this may | |
| 856 | 490 result in illegal bytes in your text! |
| 595 | 491 ++bad=drop Remove the bad characters. |
| 492 | |
| 493 The default is like "++bad=?": Replace each bad character with a question | |

497 give an error when you add it. E.g. |:write|. |
| 595 | 498 |
| 7 | 499 Note that when reading, the 'fileformat' and 'fileencoding' options will be |
| 500 set to the used format. When writing this doesn't happen, thus a next write | |
| 501 will use the old value of the option. Same for the 'binary' option. | |
| 502 | |
| 503 | |
| 504 *+cmd* *[+cmd]* | |
| 505 The [+cmd] argument can be used to position the cursor in the newly opened | |
| 506 file, or execute any other command: | |
| 507 + Start at the last line. | |
| 508 +{num} Start at line {num}. | |
| 509 +/{pat} Start at first line containing {pat}. | |
| 510 +{command} Execute {command} after opening the new file. | |
| 511 {command} is any Ex command. | |
| 512 To include a white space in the {pat} or {command}, precede it with a | |
| 513 backslash. Double the number of backslashes. > | |
| 514 :edit +/The\ book file | |
| 515 :edit +/dir\ dirname\\ file | |
| 516 :edit +set\ dir=c:\\\\temp file | |
| 517 Note that in the last example the number of backslashes is halved twice: Once | |
| 518 for the "+cmd" argument and once for the ":set" command. | |
| 519 | |
| 520 *file-formats* | |
| 521 The 'fileformat' option sets the <EOL> style for a file: | |
| 522 'fileformat' characters name ~ | |
| 523 "dos" <CR><NL> or <NL> DOS format *DOS-format* | |
| 524 "unix" <NL> Unix format *Unix-format* | |
| 525 "mac" <CR> Mac format *Mac-format* | |
| 526 Previously 'textmode' was used. It is obsolete now. | |

| 7 | 532 |
| 533 When writing a file, the mentioned characters are used for <EOL>. For DOS | |
| 534 format <CR><NL> is used. Also see |DOS-format-write|. | |
| 535 | |
| 536 You can read a file in DOS format and write it in Unix format. This will | |
| 537 replace all <CR><NL> pairs by <NL> (assuming 'fileformats' includes "dos"): > | |
| 538 :e file | |
| 539 :set fileformat=unix | |
| 540 :w | |
| 541 If you read a file in Unix format and write with DOS format, all <NL> | |
| 542 characters will be replaced with <CR><NL> (assuming 'fileformats' includes | |
| 543 "unix"): > | |
| 544 :e file | |
| 545 :set fileformat=dos | |
| 546 :w | |
| 547 | |
| 548 If you start editing a new file and the 'fileformats' option is not empty | |
| 549 (which is the default), Vim will try to detect whether the lines in the file | |
| 550 are separated by the specified formats. When set to "unix,dos", Vim will | |
| 551 check for lines with a single <NL> (as used on Unix and Amiga) or by a <CR> | |
| 18972 | 552 <NL> pair (MS-Windows). Only when ALL lines end in <CR><NL>, 'fileformat' is |
| 553 set to "dos", otherwise it is set to "unix". When 'fileformats' includes | |
| 554 "mac", and no <NL> characters are found in the file, 'fileformat' is set to | |
| 555 "mac". | |
| 7 | 556 |
| 18972 | 557 If the 'fileformat' option is set to "dos" on non-MS-Windows systems the |
| 558 message "[dos format]" is shown to remind you that something unusual is | |
| 559 happening. On MS-Windows systems you get the message "[unix format]" if | |
| 560 'fileformat' is set to "unix". On all systems but the Macintosh you get the | |
| 561 message "[mac format]" if 'fileformat' is set to "mac". | |
| 7 | 562 |
| 563 If the 'fileformats' option is empty and DOS format is used, but while reading | |
| 564 a file some lines did not end in <CR><NL>, "[CR missing]" will be included in | |
| 565 the file message. | |
| 566 If the 'fileformats' option is empty and Mac format is used, but while reading | |
| 567 a file a <NL> was found, "[NL missing]" will be included in the file message. | |
| 568 | |
| 569 If the new file does not exist, the 'fileformat' of the current buffer is used | |
| 570 when 'fileformats' is empty. Otherwise the first format from 'fileformats' is | |
| 571 used for the new file. | |
| 572 | |
| 573 Before editing binary, executable or Vim script files you should set the | |
| 574 'binary' option. A simple way to do this is by starting Vim with the "-b" | |
| 575 option. This will avoid the use of 'fileformat'. Without this you risk that | |
| 576 single <NL> characters are unexpectedly replaced with <CR><NL>. | |
| 577 | |
| 578 You can encrypt files that are written by setting the 'key' option. This | |
| 579 provides some security against others reading your files. |encryption| | |

| 39 | 620 3. The argument list *argument-list* *arglist* |
| 7 | 621 |
| 622 If you give more than one file name when starting Vim, this list is remembered | |
| 623 as the argument list. You can jump to each file in this list. | |
| 624 | |
| 625 Do not confuse this with the buffer list, which you can see with the | |
| 626 |:buffers| command. The argument list was already present in Vi, the buffer | |
| 39 | 627 list is new in Vim. Every file name in the argument list will also be present |
| 628 in the buffer list (unless it was deleted with |:bdel| or |:bwipe|). But it's | |
| 629 common that names in the buffer list are not in the argument list. | |
| 7 | 630 |
| 631 This subject is introduced in section |07.2| of the user manual. | |
| 632 | |
| 633 There is one global argument list, which is used for all windows by default. | |
| 634 It is possible to create a new argument list local to a window, see | |
| 635 |:arglocal|. | |
| 636 | |
| 637 You can use the argument list with the following commands, and with the | |
| 638 expression functions |argc()| and |argv()|. These all work on the argument | |
| 639 list of the current window. | |
| 640 | |
| 17036 | 641 *:ar* *:arg* *:args* |
| 7 | 642 :ar[gs] Print the argument list, with the current file in |
| 643 square brackets. | |
| 644 | |
| 645 :ar[gs] [++opt] [+cmd] {arglist} *:args_f* | |
| 646 Define {arglist} as the new argument list and edit | |
| 647 the first one. This fails when changes have been made | |
| 648 and Vim does not want to |abandon| the current buffer. | |
| 649 Also see |++opt| and |+cmd|. | |
| 650 | |
| 651 :ar[gs]! [++opt] [+cmd] {arglist} *:args_f!* | |
| 652 Define {arglist} as the new argument list and edit | |
| 653 the first one. Discard any changes to the current | |
| 654 buffer. | |
| 655 Also see |++opt| and |+cmd|. | |

| 6421 | 672 omitted add the current buffer name to the argument |
| 6238 | 673 list. |
| 7 | 674 If [count] is omitted, the {name}s are added just |
| 675 after the current entry in the argument list. | |
| 676 Otherwise they are added after the [count]'th file. | |
| 677 If the argument list is "a b c", and "b" is the | |

| 815 The [count] in the commands above defaults to one. For some commands it is | |
| 816 possible to use two counts. The last one (rightmost one) is used. | |
| 817 | |
| 818 If no [+cmd] argument is present, the cursor is positioned at the last known | |
| 819 cursor position for the file. If 'startofline' is set, the cursor will be | |
| 820 positioned at the first non-blank in the line, otherwise the last know column | |
| 821 is used. If there is no last known cursor position the cursor will be in the | |
| 822 first line (the last line in Ex mode). | |
| 823 | |
| 39 | 824 *{arglist}* |
| 7 | 825 The wildcards in the argument list are expanded and the file names are sorted. |
| 826 Thus you can use the command "vim *.c" to edit all the C files. From within | |
| 39 | 827 Vim the command ":n *.c" does the same. |
| 828 | |
| 829 White space is used to separate file names. Put a backslash before a space or | |
| 1240 | 830 tab to include it in a file name. E.g., to edit the single file "foo bar": > |
| 39 | 831 :next foo\ bar |
| 832 | |
| 833 On Unix and a few other systems you can also use backticks, for example: > | |
| 834 :next `find . -name \\*.c -print` | |
| 7 | 835 The backslashes before the star are required to prevent "*.c" to be expanded |
| 836 by the shell before executing the find program. | |
| 837 | |
| 838 *arglist-position* | |
| 839 When there is an argument list you can see which file you are editing in the | |
| 840 title of the window (if there is one and 'title' is on) and with the file | |
| 841 message you get with the "CTRL-G" command. You will see something like | |
| 842 (file 4 of 11) | |
| 843 If 'shortmess' contains 'f' it will be | |
| 844 (4 of 11) | |
| 845 If you are not really editing the file at the current position in the argument | |
| 846 list it will be | |
| 847 (file (4) of 11) | |
| 848 This means that you are position 4 in the argument list, but not editing the | |
| 849 fourth file in the argument list. This happens when you do ":e file". | |
| 850 | |
| 851 | |
| 852 LOCAL ARGUMENT LIST | |
| 853 | |
| 854 *:arglocal* | |
| 855 :argl[ocal] Make a local copy of the global argument list. | |
| 856 Doesn't start editing another file. | |
| 857 | |
| 858 :argl[ocal][!] [++opt] [+cmd] {arglist} | |
| 859 Define a new argument list, which is local to the | |
| 860 current window. Works like |:args_f| otherwise. | |
| 861 | |
| 862 *:argglobal* | |
| 863 :argg[lobal] Use the global argument list for the current window. | |
| 864 Doesn't start editing another file. | |
| 865 | |
| 866 :argg[lobal][!] [++opt] [+cmd] {arglist} | |
| 867 Use the global argument list for the current window. | |
| 868 Define a new global argument list like |:args_f|. | |
| 869 All windows using the global argument list will see | |
| 870 this new list. | |
| 871 | |
| 872 There can be several argument lists. They can be shared between windows. | |
| 873 When they are shared, changing the argument list in one window will also | |
| 874 change it in the other window. | |
| 875 | |
| 876 When a window is split the new window inherits the argument list from the | |
| 877 current window. The two windows then share this list, until one of them uses | |
| 878 |:arglocal| or |:argglobal| to use another argument list. | |
| 879 | |
| 880 | |
| 881 USING THE ARGUMENT LIST | |
| 882 | |
| 883 *:argdo* | |
| 6474 | 884 :[range]argdo[!] {cmd} Execute {cmd} for each file in the argument list or |
| 885 if [range] is specified only for arguments in that | |
| 886 range. It works like doing this: > | |
| 7 | 887 :rewind |
| 888 :{cmd} | |
| 889 :next | |
| 890 :{cmd} | |
| 891 etc. | |
| 892 < When the current file can't be |abandon|ed and the [!] | |
| 893 is not present, the command fails. | |
| 894 When an error is detected on one file, further files | |
| 895 in the argument list will not be visited. | |
| 896 The last file in the argument list (or where an error | |
| 897 occurred) becomes the current file. | |
| 898 {cmd} can contain '|' to concatenate several commands. | |
| 899 {cmd} must not change the argument list. | |
| 900 Note: While this command is executing, the Syntax | |
| 901 autocommand event is disabled by adding it to | |
| 902 'eventignore'. This considerably speeds up editing | |
| 903 each file. | |

910 This sets the 'fileformat' option to "unix" and writes the file if it is now |
| 7 | 911 changed. This is done for all *.c files. |
| 912 | |
| 913 Example: > | |
| 914 :args *.[ch] | |
| 915 :argdo %s/\<my_foo\>/My_Foo/ge | update | |
| 916 This changes the word "my_foo" to "My_Foo" in all *.c and *.h files. The "e" | |
| 917 flag is used for the ":substitute" command to avoid an error for files where | |
| 918 "my_foo" isn't used. ":update" writes the file only if changes were made. | |

| 27321 | 927 *E512* *E514* *E667* *E949* |
| 1702 | 928 :w[rite] [++opt] Write the whole buffer to the current file. This is |
| 7 | 929 the normal way to save changes to a file. It fails |
| 930 when the 'readonly' option is set or when there is | |
| 931 another reason why the file can't be written. | |
| 1702 | 932 For ++opt see |++opt|, but only ++bin, ++nobin, ++ff |
| 933 and ++enc are effective. | |
| 7 | 934 |
| 1702 | 935 :w[rite]! [++opt] Like ":write", but forcefully write when 'readonly' is |
| 7 | 936 set or there is another reason why writing was |
| 937 refused. | |
| 938 Note: This may change the permission and ownership of | |
| 939 the file and break (symbolic) links. Add the 'W' flag | |
| 940 to 'cpoptions' to avoid this. | |
| 941 | |
| 1702 | 942 :[range]w[rite][!] [++opt] |
| 943 Write the specified lines to the current file. This | |
| 7 | 944 is unusual, because the file will not contain all |
| 945 lines in the buffer. | |
| 946 | |
| 947 *:w_f* *:write_f* | |
| 1702 | 948 :[range]w[rite] [++opt] {file} |
| 949 Write the specified lines to {file}, unless it | |
| 7 | 950 already exists and the 'writeany' option is off. |
| 951 | |
| 952 *:w!* | |
| 1702 | 953 :[range]w[rite]! [++opt] {file} |
| 954 Write the specified lines to {file}. Overwrite an | |
| 7 | 955 existing file. |
| 956 | |
| 957 *:w_a* *:write_a* *E494* | |
| 1702 | 958 :[range]w[rite][!] [++opt] >> |
| 959 Append the specified lines to the current file. | |
| 7 | 960 |
| 1702 | 961 :[range]w[rite][!] [++opt] >> {file} |
| 7 | 962 Append the specified lines to {file}. '!' forces the |
| 963 write even if file does not exist. | |
| 964 | |
| 965 *:w_c* *:write_c* | |
| 1702 | 966 :[range]w[rite] [++opt] !{cmd} |
| 967 Execute {cmd} with [range] lines as standard input | |
| 7 | 968 (note the space in front of the '!'). {cmd} is |
| 969 executed like with ":!{cmd}", any '!' is replaced with | |
| 970 the previous command |:!|. | |
| 971 | |
| 31 | 972 The default [range] for the ":w" command is the whole buffer (1,$). If you |
| 1620 | 973 write the whole buffer, it is no longer considered changed. When you |
| 974 write it to a different file with ":w somefile" it depends on the "+" flag in | |
| 975 'cpoptions'. When included, the write command will reset the 'modified' flag, | |
| 976 even though the buffer itself may still be different from its file. | |
| 31 | 977 |
| 7 | 978 If a file name is given with ":w" it becomes the alternate file. This can be |
| 979 used, for example, when the write fails and you want to try again later with | |
| 980 ":w #". This can be switched off by removing the 'A' flag from the | |
| 981 'cpoptions' option. | |
| 982 | |
| 12909 | 983 Note that the 'fsync' option matters here. If it's set it may make writes |
| 984 slower (but safer). | |
| 985 | |
| 7 | 986 *:sav* *:saveas* |
| 1702 | 987 :sav[eas][!] [++opt] {file} |
| 988 Save the current buffer under the name {file} and set | |
| 7 | 989 the filename of the current buffer to {file}. The |
| 990 previous name is used for the alternate file name. | |
| 991 The [!] is needed to overwrite an existing file. | |
| 633 | 992 When 'filetype' is empty filetype detection is done |
| 993 with the new name, before the file is written. | |
| 819 | 994 When the write was successful 'readonly' is reset. |
| 7 | 995 |
| 996 *:up* *:update* | |
| 1702 | 997 :[range]up[date][!] [++opt] [>>] [file] |

| 1013 | |
| 1014 Vim will warn you if you try to overwrite a file that has been changed | |
| 1015 elsewhere. See |timestamp|. | |
| 1016 | |
| 1017 *backup* *E207* *E506* *E507* *E508* *E509* *E510* | |
| 1018 If you write to an existing file (but do not append) while the 'backup', | |
| 1019 'writebackup' or 'patchmode' option is on, a backup of the original file is | |
| 1020 made. The file is either copied or renamed (see 'backupcopy'). After the | |
| 1021 file has been successfully written and when the 'writebackup' option is on and | |
| 1022 the 'backup' option is off, the backup file is deleted. When the 'patchmode' | |
| 1023 option is on the backup file may be renamed. | |
| 1024 | |
| 1025 *backup-table* | |
| 1026 'backup' 'writebackup' action ~ | |
| 1027 off off no backup made | |
| 1028 off on backup current file, deleted afterwards (default) | |
| 1029 on off delete old backup, backup current file | |
| 1030 on on delete old backup, backup current file | |
| 1031 | |
| 1032 When the 'backupskip' pattern matches with the name of the file which is | |
| 1033 written, no backup file is made. The values of 'backup' and 'writebackup' are | |
| 1034 ignored then. | |
| 1035 | |
| 1036 When the 'backup' option is on, an old backup file (with the same name as the | |
| 1037 new backup file) will be deleted. If 'backup' is not set, but 'writebackup' | |
| 1038 is set, an existing backup file will not be deleted. The backup file that is | |
| 1039 made while the file is being written will have a different name. | |
| 1040 | |
| 1041 On some filesystems it's possible that in a crash you lose both the backup and | |
| 1042 the newly written file (it might be there but contain bogus data). In that | |
| 1043 case try recovery, because the swap file is synced to disk and might still be | |
| 1044 there. |:recover| | |

1046 The directories given with the 'backupdir' option are used to put the backup |
| 7 | 1047 file in. (default: same directory as the written file). |
| 1048 | |
| 1049 Whether the backup is a new file, which is a copy of the original file, or the | |
| 1050 original file renamed depends on the 'backupcopy' option. See there for an | |
| 1051 explanation of when the copy is made and when the file is renamed. | |
| 1052 | |
| 1053 If the creation of a backup file fails, the write is not done. If you want | |
| 1054 to write anyway add a '!' to the command. | |

| 7 | 1061 *write-readonly* |
| 1062 When the 'cpoptions' option contains 'W', Vim will refuse to overwrite a | |
| 1063 readonly file. When 'W' is not present, ":w!" will overwrite a readonly file, | |
| 1064 if the system allows it (the directory must be writable). | |
| 1065 | |
| 1066 *write-fail* | |
| 1067 If the writing of the new file fails, you have to be careful not to lose | |
| 1068 your changes AND the original file. If there is no backup file and writing | |
| 236 | 1069 the new file failed, you have already lost the original file! DON'T EXIT VIM |
| 1070 UNTIL YOU WRITE OUT THE FILE! If a backup was made, it is put back in place | |
| 7 | 1071 of the original file (if possible). If you exit Vim, and lose the changes |
| 1072 you made, the original file will mostly still be there. If putting back the | |
| 1073 original file fails, there will be an error message telling you that you | |
| 1074 lost the original file. | |

| 1086 | |
| 1087 See also |file-formats| and the 'fileformat' and 'fileformats' options. | |
| 1088 | |
| 1089 *ACL* | |
| 1090 ACL stands for Access Control List. It is an advanced way to control access | |
| 1091 rights for a file. It is used on new MS-Windows and Unix systems, but only | |
| 1092 when the filesystem supports it. | |
| 1093 Vim attempts to preserve the ACL info when writing a file. The backup file | |
| 1094 will get the ACL info of the original file. | |
| 1095 The ACL info is also used to check if a file is read-only (when opening the | |
| 1096 file). | |
| 1097 | |
| 1098 *read-only-share* | |
| 1099 When MS-Windows shares a drive on the network it can be marked as read-only. | |
| 1100 This means that even if the file read-only attribute is absent, and the ACL | |
| 1101 settings on NT network shared drives allow writing to the file, you can still | |
| 1102 not write to the file. Vim on Win32 platforms will detect read-only network | |
| 1103 drives and will mark the file as read-only. You will not be able to override | |
| 1104 it with |:write|. | |
| 1105 | |
| 1106 *write-device* | |
| 1107 When the file name is actually a device name, Vim will not make a backup (that | |
| 1108 would be impossible). You need to use "!", since the device already exists. | |
| 1109 Example for Unix: > | |
| 1110 :w! /dev/lpt0 | |
| 18972 | 1111 and for MS-Windows: > |
| 7 | 1112 :w! lpt0 |
| 1113 For Unix a device is detected when the name doesn't refer to a normal file or | |
| 1114 a directory. A fifo or named pipe also looks like a device to Vim. | |
| 18972 | 1115 For MS-Windows the device is detected by its name: |
| 7 | 1116 AUX |
| 1117 CON | |
| 1118 CLOCK$ | |
| 1119 NUL | |
| 1120 PRN | |
| 1121 COMn n=1,2,3... etc | |
| 1122 LPTn n=1,2,3... etc | |
| 1123 The names can be in upper- or lowercase. | |

| 1242 :conf[irm] {command} Execute {command}, and use a dialog when an | |
| 1243 operation has to be confirmed. Can be used on the | |
| 3445 | 1244 |:q|, |:qa| and |:w| commands (the latter to override |
| 1245 a read-only setting), and any other command that can | |
| 1246 fail in such a way, such as |:only|, |:buffer|, | |
| 1247 |:bdelete|, etc. | |
| 39 | 1248 |
| 1249 Examples: > | |
| 1250 :confirm w foo | |
| 1251 < Will ask for confirmation when "foo" already exists. > | |
| 1252 :confirm q | |
| 1253 < Will ask for confirmation when there are changes. > | |
| 1254 :confirm qa | |
| 1255 < If any modified, unsaved buffers exist, you will be prompted to save | |
| 1256 or abandon each one. There are also choices to "save all" or "abandon | |
| 1257 all". | |

1280 See also |:oldfiles| for ":browse oldfiles". |
| 39 | 1281 |
| 1282 The syntax is best shown via some examples: > | |
| 1283 :browse e $vim/foo | |
| 1284 < Open the browser in the $vim/foo directory, and edit the | |
| 1285 file chosen. > | |
| 1286 :browse e | |
| 1287 < Open the browser in the directory specified with 'browsedir', | |
| 1288 and edit the file chosen. > | |
| 1289 :browse w | |
| 1290 < Open the browser in the directory of the current buffer, | |
| 1291 with the current buffer filename as default, and save the | |
| 1292 buffer under the filename chosen. > | |
| 1293 :browse w C:/bar | |
| 1294 < Open the browser in the C:/bar directory, with the current | |
| 1295 buffer filename as default, and save the buffer under the | |
| 1296 filename chosen. | |
| 18016 | 1297 Also see the 'browsedir' option. |
| 39 | 1298 For versions of Vim where browsing is not supported, the command is executed |
| 1299 unmodified. | |
| 1300 | |
| 1301 *browsefilter* | |
| 24387 | 1302 For MS-Windows and GTK, you can modify the filters that are used in the browse |
| 3682 | 1303 dialog. By setting the g:browsefilter or b:browsefilter variables, you can |
| 1304 change the filters globally or locally to the buffer. The variable is set to | |
| 1305 a string in the format "{filter label}\t{pattern};{pattern}\n" where {filter | |
| 1306 label} is the text that appears in the "Files of Type" comboBox, and {pattern} | |
| 1307 is the pattern which filters the filenames. Several patterns can be given, | |
| 1308 separated by ';'. | |
| 39 | 1309 |
| 1310 For Motif the same format is used, but only the very first pattern is actually | |
| 1311 used (Motif only offers one pattern, but you can edit it). | |
| 1312 | |
| 1313 For example, to have only Vim files in the dialog, you could use the following | |
| 1314 command: > | |
| 1315 | |
| 3682 | 1316 let g:browsefilter = "Vim Scripts\t*.vim\nVim Startup Files\t*vimrc\n" |
| 39 | 1317 |
| 1318 You can override the filter setting on a per-buffer basis by setting the | |
| 1319 b:browsefilter variable. You would most likely set b:browsefilter in a | |
| 1320 filetype plugin, so that the browse dialog would contain entries related to | |
| 1321 the type of file you are currently editing. Disadvantage: This makes it | |
| 1322 difficult to start editing a file of a different type. To overcome this, you | |
| 1323 may want to add "All Files\t*.*\n" as the final filter, so that the user can | |
| 1324 still access any desired file. | |
| 1325 | |
| 3682 | 1326 To avoid setting browsefilter when Vim does not actually support it, you can |
| 1327 use has("browsefilter"): > | |
| 1328 | |
| 1329 if has("browsefilter") | |
| 1330 let g:browsefilter = "whatever" | |
| 1331 endif | |

| 39 | 1437 |
| 1438 After using |:cd| the full path name will be used for reading and writing | |
| 1439 files. On some networked file systems this may cause problems. The result of | |
| 1440 using the full path name is that the file names currently in use will remain | |
| 1441 referring to the same file. Example: If you have a file a:test and a | |
| 1442 directory a:vim the commands ":e test" ":cd vim" ":w" will overwrite the file | |
| 1443 a:test and not write a:vim/test. But if you do ":w test" the file a:vim/test | |
| 1444 will be written, because you gave a new file name and did not refer to a | |
| 1445 filename before the ":cd". | |

| 7 | 1448 8. Editing binary files *edit-binary* |
| 1449 | |
| 1450 Although Vim was made to edit text files, it is possible to edit binary | |
| 1451 files. The |-b| Vim argument (b for binary) makes Vim do file I/O in binary | |
| 1452 mode, and sets some options for editing binary files ('binary' on, 'textwidth' | |
| 1453 to 0, 'modeline' off, 'expandtab' off). Setting the 'binary' option has the | |
| 1454 same effect. Don't forget to do this before reading the file. | |
| 1455 | |
| 1456 There are a few things to remember when editing binary files: | |
| 21250 | 1457 - When editing executable files the number of bytes must not change. |
| 7 | 1458 Use only the "R" or "r" command to change text. Do not delete characters |
| 1459 with "x" or by backspacing. | |
| 1460 - Set the 'textwidth' option to 0. Otherwise lines will unexpectedly be | |
| 1461 split in two. | |
| 1462 - When there are not many <EOL>s, the lines will become very long. If you | |
| 1463 want to edit a line that does not fit on the screen reset the 'wrap' option. | |
| 1464 Horizontal scrolling is used then. If a line becomes too long (more than | |
| 21250 | 1465 about 32767 bytes on the Amiga, much more on 32-bit and 64-bit systems, see |
| 7 | 1466 |limits|) you cannot edit that line. The line will be split when reading |
| 1467 the file. It is also possible that you get an "out of memory" error when | |
| 1468 reading the file. | |
| 1469 - Make sure the 'binary' option is set BEFORE loading the | |
| 23305 | 1470 file. Otherwise both <CR><NL> and <NL> are considered to end a line |
| 1471 and when the file is written the <NL> will be replaced with <CR><NL>. | |
| 7 | 1472 - <Nul> characters are shown on the screen as ^@. You can enter them with |

1473 "CTRL-V CTRL-@" or "CTRL-V 000" |
| 7013 | 1474 - To insert a <NL> character in the file split a line. When writing the |
| 7 | 1475 buffer to a file a <NL> will be written for the <EOL>. |
| 1476 - Vim normally appends an <EOL> at the end of the file if there is none. | |
| 1477 Setting the 'binary' option prevents this. If you want to add the final | |
| 1478 <EOL>, set the 'endofline' option. You can also read the value of this | |
| 1479 option to see if there was an <EOL> for the last line (you cannot see this | |
| 1480 in the text). | |

1504 Keep in mind that without a swap file you risk losing your work in the event |

| 1507 WARNING: If you make a typo when entering the key and then write the file and | |
| 1508 exit, the text will be lost! | |
| 1509 | |
| 1510 The normal way to work with encryption, is to use the ":X" command, which will | |
| 1511 ask you to enter a key. A following write command will use that key to | |
| 1512 encrypt the file. If you later edit the same file, Vim will ask you to enter | |
| 1513 a key. If you type the same key as that was used for writing, the text will | |
| 1514 be readable again. If you use a wrong key, it will be a mess. | |
| 1515 | |
| 1516 *:X* | |
| 1517 :X Prompt for an encryption key. The typing is done without showing the | |
| 1518 actual text, so that someone looking at the display won't see it. | |
| 1519 The typed key is stored in the 'key' option, which is used to encrypt | |
| 25402 | 1520 the file when it is written. |
| 1521 The file will remain unchanged until you write it. Note that commands | |
| 1522 such as `:xit` and `ZZ` will NOT write the file unless there are other | |
| 1523 changes. | |
| 1524 See also |-x|. | |
| 7 | 1525 |
| 1526 The value of the 'key' options is used when text is written. When the option | |
| 1527 is not empty, the written file will be encrypted, using the value as the | |
| 1528 encryption key. A magic number is prepended, so that Vim can recognize that | |
| 1529 the file is encrypted. | |
| 1530 | |
| 1531 To disable the encryption, reset the 'key' option to an empty value: > | |
| 1532 :set key= | |

| 1600 Notes: | |
| 1601 - Encryption is not possible when doing conversion with 'charconvert'. | |
| 1602 - Text you copy or delete goes to the numbered registers. The registers can | |
| 1603 be saved in the .viminfo file, where they could be read. Change your | |
| 1604 'viminfo' option to be safe. | |
| 1605 - Someone can type commands in Vim when you walk away for a moment, he should | |
| 1606 not be able to get the key. | |
| 1607 - If you make a typing mistake when entering the key, you might not be able to | |
| 1608 get your text back! | |
| 1609 - If you type the key with a ":set key=value" command, it can be kept in the | |
| 1610 history, showing the 'key' value in a viminfo file. | |
| 1611 - There is never 100% safety. The encryption in Vim has not been tested for | |
| 1612 robustness. | |
| 2581 | 1613 - The algorithm used for 'cryptmethod' "zip" is breakable. A 4 character key |
| 1614 in about one hour, a 6 character key in one day (on a Pentium 133 PC). This | |
| 1615 requires that you know some text that must appear in the file. An expert | |
| 1616 can break it for any key. When the text has been decrypted, this also means | |
| 1617 that the key can be revealed, and other files encrypted with the same key | |
| 1618 can be decrypted. | |
| 1619 - Pkzip uses the same encryption as 'cryptmethod' "zip", and US Govt has no | |
| 1620 objection to its export. Pkzip's public file APPNOTE.TXT describes this | |
| 1621 algorithm in detail. | |
| 6259 | 1622 - The implementation of 'cryptmethod' "blowfish" has a flaw. It is possible |
| 1623 to crack the first 64 bytes of a file and in some circumstances more of the | |
| 6122 | 1624 file. Use of it is not recommended, but it's still the strongest method |
| 1625 supported by Vim 7.3 and 7.4. The "zip" method is even weaker. | |
| 7 | 1626 - Vim originates from the Netherlands. That is where the sources come from. |
| 1627 Thus the encryption code is not exported from the USA. | |
| 1628 | |
| 1629 ============================================================================== | |
| 1630 10. Timestamps *timestamp* *timestamps* | |
| 1631 | |
| 5908 | 1632 Vim remembers the modification timestamp, mode and size of a file when you |
| 1633 begin editing it. This is used to avoid that you have two different versions | |
| 1634 of the same file (without you knowing this). | |
| 7 | 1635 |
| 5908 | 1636 After a shell command is run (|:!cmd| |suspend| |:read!| |K|) timestamps, |
| 1637 file modes and file sizes are compared for all buffers in a window. Vim will | |
| 1638 run any associated |FileChangedShell| autocommands or display a warning for | |
| 1639 any files that have changed. In the GUI this happens when Vim regains input | |
| 1640 focus. | |
| 7 | 1641 |
| 1642 *E321* *E462* | |
| 1643 If you want to automatically reload a file when it has been changed outside of | |
| 1644 Vim, set the 'autoread' option. This doesn't work at the moment you write the | |
| 1645 file though, only when the file wasn't changed inside of Vim. | |

| 7 | 1654 Note that if a FileChangedShell autocommand is defined you will not get a |
| 1655 warning message or prompt. The autocommand is expected to handle this. | |
| 1656 | |
| 139 | 1657 There is no warning for a directory (e.g., with |netrw-browse|). But you do |
| 1658 get warned if you started editing a new file and it was created as a directory | |
| 1659 later. | |
| 7 | 1660 |
| 1661 When Vim notices the timestamp of a file has changed, and the file is being | |
| 1662 edited in a buffer but has not changed, Vim checks if the contents of the file | |
| 1663 is equal. This is done by reading the file again (into a hidden buffer, which | |
| 1664 is immediately deleted again) and comparing the text. If the text is equal, | |
| 1665 you will get no warning. | |
| 1666 | |
| 1667 If you don't get warned often enough you can use the following command. | |
| 1668 | |
| 1669 *:checkt* *:checktime* | |
| 1670 :checkt[ime] Check if any buffers were changed outside of Vim. | |
| 1671 This checks and warns you if you would end up with two | |
| 1672 versions of a file. | |
| 1673 If this is called from an autocommand, a ":global" | |
| 1674 command or is not typed the actual check is postponed | |
| 1675 until a moment the side effects (reloading the file) | |
| 1676 would be harmless. | |
| 1677 Each loaded buffer is checked for its associated file | |
| 1678 being changed. If the file was changed Vim will take | |
| 1679 action. If there are no changes in the buffer and | |
| 1680 'autoread' is set, the buffer is reloaded. Otherwise, | |
| 1681 you are offered the choice of reloading the file. If | |
| 1682 the file was deleted you get an error message. | |
| 1683 If the file previously didn't exist you get a warning | |
| 1684 if it exists now. | |
| 1685 Once a file has been checked the timestamp is reset, | |
| 1686 you will not be warned again. | |

| 7 | 1710 Before writing a file the timestamp is checked. If it has changed, Vim will |
| 1711 ask if you really want to overwrite the file: | |
| 1712 | |
| 1713 WARNING: The file has been changed since reading it!!! | |
| 1714 Do you really want to write to it (y/n)? | |
| 1715 | |
| 1716 If you hit 'y' Vim will continue writing the file. If you hit 'n' the write is | |
| 1717 aborted. If you used ":wq" or "ZZ" Vim will not exit, you will get another | |
| 1718 chance to write the file. | |
| 1719 | |
| 1720 The message would normally mean that somebody has written to the file after | |
| 1721 the edit session started. This could be another person, in which case you | |
| 1722 probably want to check if your changes to the file and the changes from the | |
| 1723 other person should be merged. Write the file under another name and check for | |
| 1724 differences (the "diff" program can be used for this). | |
| 1725 | |
| 1726 It is also possible that you modified the file yourself, from another edit | |
| 1727 session or with another command (e.g., a filter command). Then you will know | |
| 1728 which version of the file you want to keep. | |
| 1729 | |
| 25973 | 1730 The accuracy of the time check depends on the filesystem. On Unix it is |
| 28517 | 1731 usually sub-second. With old file systems and on MS-Windows it is normally one |
| 27804 | 1732 second. Use `has('nanotime')` to check if sub-second time stamp checks are |
| 25973 | 1733 available. |
| 1734 | |
| 236 | 1735 There is one situation where you get the message while there is nothing wrong: |
| 1736 On a Win32 system on the day daylight saving time starts. There is something | |
| 1737 in the Win32 libraries that confuses Vim about the hour time difference. The | |
| 1738 problem goes away the next day. | |
| 1739 | |
| 39 | 1740 ============================================================================== |
| 1741 11. File Searching *file-searching* | |
| 1742 | |
| 1743 The file searching is currently used for the 'path', 'cdpath' and 'tags' | |
| 1668 | 1744 options, for |finddir()| and |findfile()|. Other commands use |wildcards| |
| 1745 which is slightly different. | |
| 1121 | 1746 |
| 1747 There are three different types of searching: | |
| 39 | 1748 |
| 444 | 1749 1) Downward search: *starstar* |
| 39 | 1750 Downward search uses the wildcards '*', '**' and possibly others |
| 1668 | 1751 supported by your operating system. '*' and '**' are handled inside Vim, |
| 1752 so they work on all operating systems. Note that "**" only acts as a | |
| 1753 special wildcard when it is at the start of a name. | |
| 39 | 1754 |
| 1620 | 1755 The usage of '*' is quite simple: It matches 0 or more characters. In a |
| 1756 search pattern this would be ".*". Note that the "." is not used for file | |
| 1757 searching. | |
| 39 | 1758 |
| 1759 '**' is more sophisticated: | |
| 1760 - It ONLY matches directories. | |
| 1668 | 1761 - It matches up to 30 directories deep by default, so you can use it to |
| 1762 search an entire directory tree | |
| 39 | 1763 - The maximum number of levels matched can be given by appending a number |
| 1764 to '**'. | |
| 1765 Thus '/usr/**2' can match: > | |
| 1766 /usr | |
| 1767 /usr/include | |
| 1768 /usr/include/sys | |
| 1769 /usr/include/g++ | |
| 1770 /usr/lib | |
| 1771 /usr/lib/X11 | |
| 1772 .... | |
| 1773 < It does NOT match '/usr/include/g++/std' as this would be three | |
| 1774 levels. | |
| 1668 | 1775 The allowed number range is 0 ('**0' is removed) to 100 |
| 39 | 1776 If the given number is smaller than 0 it defaults to 30, if it's |
| 1668 | 1777 bigger than 100 then 100 is used. The system also has a limit on the |
| 1778 path length, usually 256 or 1024 bytes. | |
| 39 | 1779 - '**' can only be at the end of the path or be followed by a path |
| 1780 separator or by a number and a path separator. | |
| 1781 | |
| 1782 You can combine '*' and '**' in any order: > | |
| 1783 /usr/**/sys/* | |
| 1668 | 1784 /usr/*tory/sys/** |
| 39 | 1785 /usr/**2/sys/* |
| 1786 | |
| 1787 2) Upward search: | |
| 1788 Here you can give a directory and then search the directory tree upward for | |
| 236 | 1789 a file. You could give stop-directories to limit the upward search. The |
| 39 | 1790 stop-directories are appended to the path (for the 'path' option) or to |
| 236 | 1791 the filename (for the 'tags' option) with a ';'. If you want several |
| 1792 stop-directories separate them with ';'. If you want no stop-directory | |
| 39 | 1793 ("search upward till the root directory) just use ';'. > |
| 1794 /usr/include/sys;/usr | |
| 1795 < will search in: > | |
| 1796 /usr/include/sys | |
| 1797 /usr/include | |
| 1798 /usr | |
| 1799 < | |
| 1800 If you use a relative path the upward search is started in Vim's current | |
| 1801 directory or in the directory of the current file (if the relative path | |
| 1802 starts with './' and 'd' is not included in 'cpoptions'). | |
| 1803 | |
| 1804 If Vim's current path is /u/user_x/work/release and you do > | |
| 1805 :set path=include;/u/user_x | |
| 1806 < and then search for a file with |gf| the file is searched in: > | |
| 1807 /u/user_x/work/release/include | |
| 1808 /u/user_x/work/include | |
| 1809 /u/user_x/include | |
| 1810 | |
| 27036 | 1811 < Note: If your 'path' setting includes a non-existing directory, Vim will |
| 27537 | 1812 skip the non-existing directory, and also does not search in the parent of |
| 1813 the non-existing directory if upwards searching is used. | |

| 236 | 1815 3) Combined up/downward search: |
| 39 | 1816 If Vim's current path is /u/user_x/work/release and you do > |
| 1817 set path=**;/u/user_x | |
| 1818 < and then search for a file with |gf| the file is searched in: > | |
| 1819 /u/user_x/work/release/** | |
| 1820 /u/user_x/work/** | |
| 1821 /u/user_x/** | |
| 1822 < | |
| 236 | 1823 BE CAREFUL! This might consume a lot of time, as the search of |
| 39 | 1824 '/u/user_x/**' includes '/u/user_x/work/**' and |
| 1825 '/u/user_x/work/release/**'. So '/u/user_x/work/release/**' is searched | |
| 236 | 1826 three times and '/u/user_x/work/**' is searched twice. |
| 39 | 1827 |
| 1828 In the above example you might want to set path to: > | |
| 1829 :set path=**,/u/user_x/** | |

1835 Note that completion for ":find", ":sfind", and ":tabfind" commands do not |
| 11914 | 1836 currently work with 'path' items that contain a URL or use the double star |
| 3456 | 1837 with depth limiter (/usr/**2) or upward search (;) notations. |
