| 7 This file describes commands that delete or change text. In this context, | |
| 8 changing text means deleting the text and replacing it with other text using | |
| 9 one command. You can undo all of these commands. You can repeat the non-Ex | |
| 10 commands with the "." command. | |

| 28 | |
| 29 ["x]<Del> or *<Del>* *x* *dl* | |
| 30 ["x]x Delete [count] characters under and after the cursor | |
| 31 [into register x] (not |linewise|). Does the same as | |
| 32 "dl". | |
| 33 The <Del> key does not take a [count]. Instead, it | |
| 34 deletes the last character of the count. | |
| 35 See |:fixdel| if the <Del> key does not do what you | |
| 36 want. See |'whichwrap'| for deleting a line break | |

| 7 | 132 the join does not insert or delete any spaces. |
| 133 If a [range] has equal start and end values, this | |
| 134 command does nothing. The default behavior is to | |
| 135 join the current line with the line below it. | |
| 168 | 136 See |ex-flags| for [flags]. |
| 7 | 137 |
| 168 | 138 :[range]j[oin][!] {count} [flags] |
| 7 | 139 Join {count} lines, starting with [range] (default: |

| 145 These commands delete the <EOL> between lines. This has the effect of joining | |
| 3492 | 146 multiple lines into one line. You can repeat these commands (except `:j`) and |
| 7 | 147 undo them. |
| 148 | |
| 149 These commands, except "gJ", insert one space in place of the <EOL> unless | |
| 150 there is trailing white space or the next line starts with a ')'. These | |
| 151 commands, except "gJ", delete any leading white space on the next line. If | |
| 152 the 'joinspaces' option is on, these commands insert two spaces after a '.', | |
| 153 '!' or '?' (but if 'cpoptions' includes the 'j' flag, they insert two spaces | |
| 154 only after a '.'). | |
| 155 The 'B' and 'M' flags in 'formatoptions' change the behavior for inserting | |
| 156 spaces before and after a multi-byte character |fo-table|. | |

| 163 2. Delete and insert *delete-insert* *replacing* | |
| 164 | |
| 165 *R* | |
| 166 R Enter Replace mode: Each character you type replaces | |
| 167 an existing character, starting with the character | |
| 168 under the cursor. Repeat the entered text [count]-1 | |
| 169 times. See |Replace-mode| for more details. | |
| 170 | |
| 171 *gR* | |
| 172 gR Enter Virtual Replace mode: Each character you type | |
| 173 replaces existing characters in screen space. So a | |
| 174 <Tab> may replace several characters at once. | |
| 175 Repeat the entered text [count]-1 times. See | |
| 176 |Virtual-Replace-mode| for more details. | |
| 177 | |
| 178 *c* | |
| 179 ["x]c{motion} Delete {motion} text [into register x] and start | |
| 180 insert. When 'cpoptions' includes the 'E' flag and | |
| 181 there is no text to delete (e.g., with "cTx" when the | |
| 182 cursor is just after an 'x'), an error occurs and | |
| 183 insert mode does not start (this is Vi compatible). | |
| 184 When 'cpoptions' does not include the 'E' flag, the | |
| 185 "c" command always starts insert mode, even if there | |
| 186 is no text to delete. | |
| 187 | |
| 188 *cc* | |
| 189 ["x]cc Delete [count] lines [into register x] and start | |
| 190 insert |linewise|. If 'autoindent' is on, preserve | |
| 191 the indent of the first line. | |
| 192 | |
| 193 *C* | |
| 194 ["x]C Delete from the cursor position to the end of the | |
| 195 line and [count]-1 more lines [into register x], and | |
| 196 start insert. Synonym for c$ (not |linewise|). | |
| 197 | |
| 198 *s* | |
| 199 ["x]s Delete [count] characters [into register x] and start | |
| 200 insert (s stands for Substitute). Synonym for "cl" | |
| 201 (not |linewise|). | |
| 202 | |
| 203 *S* | |

223 it might work differently. |
| 7 | 224 |
| 225 Notes: | |
| 226 - You can end Insert and Replace mode with <Esc>. | |
| 227 - See the section "Insert and Replace mode" |mode-ins-repl| for the other | |
| 228 special characters in these modes. | |
| 229 - The effect of [count] takes place after Vim exits Insert or Replace mode. | |
| 230 - When the 'cpoptions' option contains '$' and the change is within one line, | |
| 231 Vim continues to show the text to be deleted and puts a '$' at the last | |
| 232 deleted character. | |
| 233 | |
| 234 See |registers| for an explanation of registers. | |
| 235 | |
| 236 Replace mode is just like Insert mode, except that every character you enter | |
| 237 deletes one character. If you reach the end of a line, Vim appends any | |
| 238 further characters (just like Insert mode). In Replace mode, the backspace | |
| 239 key restores the original text (if there was any). (See section "Insert and | |
| 240 Replace mode" |mode-ins-repl|). | |
| 241 | |
| 242 *cw* *cW* | |
| 1621 | 243 Special case: When the cursor is in a word, "cw" and "cW" do not include the |
| 244 white space after a word, they only change up to the end of the word. This is | |
| 245 because Vim interprets "cw" as change-word, and a word does not include the | |
| 246 following white space. | |
| 247 {Vi: "cw" when on a blank followed by other blanks changes only the first | |
| 248 blank; this is probably a bug, because "dw" deletes all the blanks; use the | |
| 249 'w' flag in 'cpoptions' to make it work like Vi anyway} | |
| 7 | 250 |
| 251 If you prefer "cw" to include the space after a word, use this mapping: > | |
| 252 :map cw dwi | |
| 1621 | 253 Or use "caw" (see |aw|). |
| 254 | |
| 7 | 255 *:c* *:ch* *:change* |
| 168 | 256 :{range}c[hange][!] Replace lines of text with some different text. |
| 7 | 257 Type a line containing only "." to stop replacing. |
| 258 Without {range}, this command changes only the current | |
| 259 line. | |
| 168 | 260 Adding [!] toggles 'autoindent' for the time this |
| 261 command is executed. | |
| 7 | 262 |
| 263 ============================================================================== | |
| 264 3. Simple changes *simple-change* | |
| 265 | |
| 266 *r* | |
| 267 r{char} Replace the character under the cursor with {char}. | |
| 268 If {char} is a <CR> or <NL>, a line break replaces the | |
| 269 character. To replace with a real <CR>, use CTRL-V | |
| 270 <CR>. CTRL-V <NL> replaces with a <Nul>. | |

| 7 | 277 If you give a [count], Vim replaces [count] characters |
| 278 with [count] {char}s. When {char} is a <CR> or <NL>, | |
| 279 however, Vim inserts only one <CR>: "5r<CR>" replaces | |
| 280 five characters with a single line break. | |
| 281 When {char} is a <CR> or <NL>, Vim performs | |
| 282 autoindenting. This works just like deleting the | |
| 283 characters that are replaced and then doing | |
| 284 "i<CR><Esc>". | |
| 285 {char} can be entered as a digraph |digraph-arg|. | |
| 286 |:lmap| mappings apply to {char}. The CTRL-^ command | |
| 287 in Insert mode can be used to switch this on/off | |
| 288 |i_CTRL-^|. See |utf-8-char-arg| about using | |
| 289 composing characters when 'encoding' is Unicode. | |
| 290 | |
| 291 *gr* | |
| 292 gr{char} Replace the virtual characters under the cursor with | |
| 293 {char}. This replaces in screen space, not file | |
| 294 space. See |gR| and |Virtual-Replace-mode| for more | |
| 295 details. As with |r| a count may be given. | |
| 296 {char} can be entered like with |r|. | |
| 297 | |
| 298 *digraph-arg* | |
| 299 The argument for Normal mode commands like |r| and |t| is a single character. | |
| 300 When 'cpo' doesn't contain the 'D' flag, this character can also be entered | |
| 301 like |digraphs|. First type CTRL-K and then the two digraph characters. | |
| 302 {not available when compiled without the |+digraphs| feature} | |
| 303 | |
| 304 *case* | |
| 305 The following commands change the case of letters. The currently active | |
| 306 |locale| is used. See |:language|. The LC_CTYPE value matters here. | |
| 307 | |
| 308 *~* | |
| 309 ~ 'notildeop' option: Switch case of the character | |
| 310 under the cursor and move the cursor to the right. | |
| 16610 | 311 If a [count] is given, do that many characters. |
| 7 | 312 |
| 16610 | 313 ~{motion} 'tildeop' option: switch case of {motion} text. |

420 '0B' are binary. |
| 36 | 421 - When 'nrformats' includes "octal", Vim considers numbers starting with a '0' |
| 39 | 422 to be octal, unless the number includes a '8' or '9'. Other numbers are |
| 423 decimal and may have a preceding minus sign. | |
| 36 | 424 If the cursor is on a number, the commands apply to that number; otherwise |
| 425 Vim uses the number to the right of the cursor. | |
| 7 | 426 - When 'nrformats' includes "hex", Vim assumes numbers starting with '0x' or |
| 427 '0X' are hexadecimal. The case of the rightmost letter in the number | |
| 428 determines the case of the resulting hexadecimal number. If there is no | |
| 429 letter in the current number, Vim uses the previously detected case. | |
| 36 | 430 - When 'nrformats' includes "alpha", Vim will change the alphabetic character |
| 431 under or after the cursor. This is useful to make lists with an alphabetic | |
| 432 index. | |

435 decrementing, for binary, octal and hex values, it won't be considered. To |
| 13857 | 436 ignore the sign Visually select the number before using CTRL-A or CTRL-X. |
| 6884 | 437 |
| 7 | 438 For numbers with leading zeros (including all octal and hexadecimal numbers), |
| 439 Vim preserves the number of characters in the number when possible. CTRL-A on | |
| 36 | 440 "0077" results in "0100", CTRL-X on "0x100" results in "0x0ff". |
| 39 | 441 There is one exception: When a number that starts with a zero is found not to |
| 442 be octal (it contains a '8' or '9'), but 'nrformats' does include "octal", | |
| 443 leading zeros are removed to avoid that the result may be recognized as an | |
| 444 octal number. | |
| 36 | 445 |
| 446 Note that when 'nrformats' includes "octal", decimal numbers with leading | |
| 39 | 447 zeros cause mistakes, because they can be confused with octal numbers. |

| 517 The ">" and "<" commands are handy for changing the indentation within | |
| 518 programs. Use the 'shiftwidth' option to set the size of the white space | |
| 519 which these commands insert or delete. Normally the 'shiftwidth' option is 8, | |
| 520 but you can set it to, say, 3 to make smaller indents. The shift leftwards | |
| 521 stops when there is no indent. The shift right does not affect empty lines. | |
| 522 | |
| 523 If the 'shiftround' option is on, the indent is rounded to a multiple of | |
| 524 'shiftwidth'. | |
| 525 | |
| 526 If the 'smartindent' option is on, or 'cindent' is on and 'cinkeys' contains | |
| 5466 | 527 '#' with a zero value, shift right does not affect lines starting with '#' |
| 528 (these are supposed to be C preprocessor lines that must stay in column 1). | |
| 13735 | 529 This can be changed with the 'cino' option, see |cino-#|. |

| 531 When the 'expandtab' option is off (this is the default) Vim uses <Tab>s as | |
| 532 much as possible to make the indent. You can use ">><<" to replace an indent | |
| 533 made out of spaces with the same indent made out of <Tab>s (and a few spaces | |
| 534 if necessary). If the 'expandtab' option is on, Vim uses only spaces. Then | |
| 535 you can use ">><<" to replace <Tab>s in the indent by spaces (or use | |
| 3492 | 536 `:retab!`). |
| 7 | 537 |
| 3492 | 538 To move a line several 'shiftwidth's, use Visual mode or the `:` commands. |
| 7 | 539 For example: > |
| 540 Vjj4> move three lines 4 indents to the right | |
| 541 :<<< move current line 3 indents to the left | |
| 542 :>> 5 move 5 lines 2 indents to the right | |
| 543 :5>> move line 5 2 indents to the right | |

| 856 | 548 4.1 Filter commands *filter* |
| 32 | 549 |
| 550 A filter is a program that accepts text at standard input, changes it in some | |
| 551 way, and sends it to standard output. You can use the commands below to send | |
| 1621 | 552 some text through a filter, so that it is replaced by the filter output. |
| 32 | 553 Examples of filters are "sort", which sorts lines alphabetically, and |
| 554 "indent", which formats C program files (you need a version of indent that | |
| 555 works like a filter; not all versions do). The 'shell' option specifies the | |
| 556 shell Vim uses to execute the filter command (See also the 'shelltype' | |
| 557 option). You can repeat filter commands with ".". Vim does not recognize a | |
| 3492 | 558 comment (starting with '"') after the `:!` command. |
| 32 | 559 |
| 560 *!* | |
| 7 | 561 !{motion}{filter} Filter {motion} text lines through the external |
| 562 program {filter}. | |
| 563 | |
| 564 *!!* | |
| 565 !!{filter} Filter [count] lines through the external program | |
| 566 {filter}. | |
| 567 | |
| 568 *v_!* | |
| 569 {Visual}!{filter} Filter the highlighted lines through the external | |
| 570 program {filter} (for {Visual} see |Visual-mode|). | |
| 571 | |
| 572 :{range}![!]{filter} [!][arg] *:range!* | |
| 573 Filter {range} lines through the external program | |
| 574 {filter}. Vim replaces the optional bangs with the | |
| 575 latest given command and appends the optional [arg]. | |
| 576 Vim saves the output of the filter command in a | |

| 7 | 582 When the 'R' flag is included in 'cpoptions' marks in |
| 583 the filtered lines are deleted, unless the | |
| 584 |:keepmarks| command is used. Example: > | |
| 585 :keepmarks '<,'>!sort | |
| 586 < When the number of lines after filtering is less than | |
| 587 before, marks in the missing lines are deleted anyway. | |
| 588 | |
| 589 *=* | |
| 590 ={motion} Filter {motion} lines through the external program | |
| 591 given with the 'equalprg' option. When the 'equalprg' | |
| 592 option is empty (this is the default), use the | |
| 2833 | 593 internal formatting function |C-indenting| and |
| 594 |'lisp'|. But when 'indentexpr' is not empty, it will | |
| 595 be used instead |indent-expression|. When Vim was | |
| 596 compiled without internal formatting then the "indent" | |
| 597 program is used as a last resort. | |

| 3492 | 645 Note that after `:substitute` the '&' flag can't be |

| 7013 | 647 The space between `:substitute` and the 'c', 'g', |

| 170 | 656 *&* |
| 3492 | 657 & Synonym for `:s` (repeat last substitute). Note |

| 170 | 662 *g&* |
| 3920 | 663 g& Synonym for `:%s//~/&` (repeat last substitute with |

| 4186 | 665 For example, when you first do a substitution with |
| 3920 | 666 `:s/pattern/repl/flags` and then `/search` for |
| 667 something else, `g&` will do `:%s/search/repl/flags`. | |

| 7 | 696 If the 'edcompatible' option is on, Vim remembers the [c] flag and |
| 697 toggles it each time you use it, but resets it when you give a new | |
| 698 search pattern. | |
| 699 | |
| 14864 | 700 *:s_e* |
| 7 | 701 [e] When the search pattern fails, do not issue an error message and, in |
| 702 particular, continue in maps as if no error occurred. This is most | |
| 703 useful to prevent the "No match" error from breaking a mapping. Vim | |
| 704 does not suppress the following error messages, however: | |
| 705 Regular expressions can't be delimited by letters | |
| 706 \ should be followed by /, ? or & | |
| 707 No previous substitute regular expression | |
| 708 Trailing characters | |
| 709 Interrupted | |
| 710 | |
| 14864 | 711 *:s_g* |
| 7 | 712 [g] Replace all occurrences in the line. Without this argument, |
| 713 replacement occurs only for the first occurrence in each line. If | |
| 714 the 'edcompatible' option is on, Vim remembers this flag and toggles | |
| 715 it each time you use it, but resets it when you give a new search | |
| 716 pattern. If the 'gdefault' option is on, this flag is on by default | |
| 717 and the [g] argument switches it off. | |
| 718 | |
| 14864 | 719 *:s_i* |
| 7 | 720 [i] Ignore case for the pattern. The 'ignorecase' and 'smartcase' options |
| 721 are not used. | |
| 722 | |
| 14864 | 723 *:s_I* |
| 7 | 724 [I] Don't ignore case for the pattern. The 'ignorecase' and 'smartcase' |
| 725 options are not used. | |
| 726 | |
| 14864 | 727 *:s_n* |
| 170 | 728 [n] Report the number of matches, do not actually substitute. The [c] |
| 729 flag is ignored. The matches are reported as if 'report' is zero. | |
| 730 Useful to |count-items|. | |
| 3750 | 731 If \= |sub-replace-expression| is used, the expression will be |
| 732 evaluated in the |sandbox| at every match. | |
| 170 | 733 |
| 14864 | 734 [p] Print the line containing the last substitute. *:s_p* |
| 735 | |
| 736 [#] Like [p] and prepend the line number. *:s_#* | |
| 168 | 737 |
| 14864 | 738 [l] Like [p] but print the text like |:list|. *:s_l* |
| 168 | 739 |
| 14864 | 740 *:s_r* |
| 3492 | 741 [r] Only useful in combination with `:&` or `:s` without arguments. `:&r` |
| 742 works the same way as `:~`: When the search pattern is empty, use the | |
| 7 | 743 previously used search pattern instead of the search pattern from the |
| 3492 | 744 last substitute or `:global`. If the last command that did a search |
| 745 was a substitute or `:global`, there is no effect. If the last | |
| 7 | 746 command was a search command such as "/", use the pattern from that |
| 747 command. | |
| 3492 | 748 For `:s` with an argument this already happens: > |
| 7 | 749 :s/blue/red/ |
| 750 /green | |
| 751 :s//red/ or :~ or :&r | |
| 752 < The last commands will replace "green" with "red". > | |
| 753 :s/blue/red/ | |
| 754 /green | |
| 755 :& | |
| 756 < The last command will replace "blue" with "red". | |
| 757 | |
| 758 Note that there is no flag to change the "magicness" of the pattern. A | |
| 1621 | 759 different command is used instead, or you can use |/\v| and friends. The |
| 760 reason is that the flags can only be found by skipping the pattern, and in | |
| 761 order to skip the pattern the "magicness" must be known. Catch 22! | |
| 7 | 762 |
| 763 If the {pattern} for the substitute command is empty, the command uses the | |
| 3492 | 764 pattern from the last substitute or `:global` command. If there is none, but |
| 2725 | 765 there is a previous search pattern, that one is used. With the [r] flag, the |
| 3492 | 766 command uses the pattern from the last substitute, `:global`, or search |
| 7 | 767 command. |
| 768 | |
| 1121 | 769 If the {string} is omitted the substitute is done as if it's empty. Thus the |
| 770 matched pattern is deleted. The separator after {pattern} can also be left | |
| 771 out then. Example: > | |
| 772 :%s/TESTING | |
| 773 This deletes "TESTING" from all lines, but only one per line. | |
| 774 | |
| 7 | 775 For compatibility with Vi these two exceptions are allowed: |
| 776 "\/{string}/" and "\?{string}?" do the same as "//{string}/r". | |
| 777 "\&{string}&" does the same as "//{string}/". | |
| 778 *E146* | |
| 779 Instead of the '/' which surrounds the pattern and replacement string, you | |
| 1121 | 780 can use any other single-byte character, but not an alphanumeric character, |
| 781 '\', '"' or '|'. This is useful if you want to include a '/' in the search | |
| 782 pattern or replacement string. Example: > | |
| 7 | 783 :s+/+//+ |
| 784 | |
| 1621 | 785 For the definition of a pattern, see |pattern|. In Visual block mode, use |
| 786 |/\%V| in the pattern to have the substitute work in the block only. | |
| 787 Otherwise it works on whole lines anyway. | |
| 7 | 788 |
| 789 *sub-replace-special* *:s\=* | |
| 790 When the {string} starts with "\=" it is evaluated as an expression, see | |
| 2908 | 791 |sub-replace-expression|. You can use that for complex replacement or special |
| 792 characters. | |
| 793 | |
| 452 | 794 Otherwise these characters in {string} have a special meaning: |
| 168 | 795 *:s%* |
| 843 | 796 When {string} is equal to "%" and '/' is included with the 'cpoptions' option, |
| 2908 | 797 then the {string} of the previous substitute command is used, see |cpo-/| |
| 7 | 798 |

| 828 \\ insert a single backslash *s/\\* | |
| 829 \x where x is any character not mentioned above: | |
| 830 Reserved for future expansion | |
| 831 | |
| 2908 | 832 The special meaning is also used inside the third argument {sub} of |
| 833 the |substitute()| function with the following exceptions: | |
| 834 - A % inserts a percent literally without regard to 'cpoptions'. | |
| 835 - magic is always set without regard to 'magic'. | |
| 836 - A ~ inserts a tilde literally. | |
| 837 - <CR> and \r inserts a carriage-return (CTRL-M). | |

846 :s/\w\+/\L\u\0/g modifies "BLA bla" to "Bla Bla" |
| 4264 | 847 |
| 848 Note: "\L\u" can be used to capitalize the first letter of a word. This is | |
| 849 not compatible with Vi and older versions of Vim, where the "\u" would cancel | |
| 850 out the "\L". Same for "\U\l". | |
| 7 | 851 |
| 852 Note: In previous versions CTRL-V was handled in a special way. Since this is | |
| 853 not Vi compatible, this was removed. Use a backslash instead. | |

| 859 | |
| 860 (you need to type CTRL-V <CR> to get a ^M here) | |
| 861 | |
| 862 The numbering of "\1", "\2" etc. is done based on which "\(" comes first in | |
| 863 the pattern (going left to right). When a parentheses group matches several | |
| 864 times, the last one will be used for "\1", "\2", etc. Example: > | |
| 865 :s/\(\(a[a-d] \)*\)/\2/ modifies "aa ab x" to "ab x" | |

866 The "\2" is for "\(a[a-d] \)". At first it matches "aa ", secondly "ab ". |
| 7 | 867 |
| 868 When using parentheses in combination with '|', like in \([ab]\)\|\([cd]\), | |
| 869 either the first or second pattern in parentheses did not match, so either | |
| 870 \1 or \2 is empty. Example: > | |
| 871 :s/\([ab]\)\|\([cd]\)/\1x/g modifies "a b c d" to "ax bx x x" | |

907 expression. |
| 7 | 908 |
| 909 The special meaning for characters as mentioned at |sub-replace-special| does | |
| 2908 | 910 not apply except for "<CR>". A <NL> character is used as a line break, you |
| 911 can get one with a double-quote string: "\n". Prepend a backslash to get a | |
| 912 real <NL> character (which will be a NUL in the file). | |
| 7 | 913 |
| 2908 | 914 The "\=" notation can also be used inside the third argument {sub} of |
| 915 |substitute()| function. In this case, the special meaning for characters as | |
| 916 mentioned at |sub-replace-special| does not apply at all. Especially, <CR> and | |
| 917 <NL> are interpreted not as a line break but as a carriage-return and a | |
| 918 new-line respectively. | |
| 7 | 919 |
| 714 | 920 When the result is a |List| then the items are joined with separating line |
| 921 breaks. Thus each item becomes a line, except that they can contain line | |
| 922 breaks themselves. | |
| 923 | |
| 15194 | 924 The |submatch()| function can be used to obtain matched text. The whole |
| 925 matched text can be accessed with "submatch(0)". The text matched with the | |
| 926 first pair of () with "submatch(1)". Likewise for further sub-matches in (). | |
| 7 | 927 |
| 928 Be careful: The separation character must not appear in the expression! | |
| 929 Consider using a character like "@" or ":". There is no problem if the result | |
| 930 of the expression contains the separation character. | |
| 931 | |
| 452 | 932 Examples: > |
| 7 | 933 :s@\n@\="\r" . expand("$HOME") . "\r"@ |
| 452 | 934 This replaces an end-of-line with a new line containing the value of $HOME. > |
| 935 | |
| 936 s/E/\="\<Char-0x20ac>"/g | |
| 1668 | 937 This replaces each 'E' character with a euro sign. Read more in |<Char->|. |

| 941 | |
| 942 *:pro* *:promptfind* | |
| 7 | 943 :promptf[ind] [string] |
| 944 Put up a Search dialog. When [string] is given, it is | |
| 945 used as the initial search string. | |
| 946 {only for Win32, Motif and GTK GUI} | |
| 947 | |
| 948 *:promptr* *:promptrepl* | |
| 949 :promptr[epl] [string] | |
| 950 Put up a Search/Replace dialog. When [string] is | |
| 951 given, it is used as the initial search string. | |
| 952 {only for Win32, Motif and GTK GUI} | |
| 953 | |

| 955 4.4 Changing tabs *change-tabs* | |
| 3492 | 956 *:ret* *:retab* *:retab!* |
| 7 | 957 :[range]ret[ab][!] [new_tabstop] |
| 958 Replace all sequences of white-space containing a | |
| 959 <Tab> with new strings of white-space using the new | |
| 960 tabstop value given. If you do not specify a new | |
| 961 tabstop size or it is zero, Vim uses the current value | |
| 962 of 'tabstop'. | |
| 963 The current value of 'tabstop' is always used to | |
| 964 compute the width of existing tabs. | |
| 965 With !, Vim also replaces strings of only normal | |
| 966 spaces with tabs where appropriate. | |
| 967 With 'expandtab' on, Vim replaces all tabs with the | |
| 968 appropriate number of spaces. | |
| 969 This command sets 'tabstop' to the new value given, | |
| 970 and if performed on the whole file, which is default, | |
| 971 should not make any visible change. | |
| 972 Careful: This command modifies any <Tab> characters | |
| 973 inside of strings in a C program. Use "\t" to avoid | |
| 974 this (that's a good habit anyway). | |
| 3492 | 975 `:retab!` may also change a sequence of spaces by |
| 7 | 976 <Tab> characters, which can mess up a printf(). |

1113 or 'a'. |
| 7 | 1114 |
| 1115 You can use these commands to copy text from one place to another. Do this | |
| 1116 by first getting the text into a register with a yank, delete or change | |
| 1117 command, then inserting the register contents with a put command. You can | |
| 1118 also use these commands to move text from one file to another, because Vim | |
| 1119 preserves all registers when changing buffers (the CTRL-^ command is a quick | |
| 1120 way to toggle between two files). | |
| 1121 | |
| 1122 *linewise-register* *characterwise-register* | |
| 1123 You can repeat the put commands with "." (except for :put) and undo them. If | |
| 1124 the command that was used to get the text into the register was |linewise|, | |
| 1125 Vim inserts the text below ("p") or above ("P") the line where the cursor is. | |
| 1126 Otherwise Vim inserts the text after ("p") or before ("P") the cursor. With | |
| 1127 the ":put" command, Vim always inserts the text in the next line. You can | |
| 1128 exchange two characters with the command sequence "xp". You can exchange two | |
| 1129 lines with the command sequence "ddp". You can exchange two words with the | |
| 1130 command sequence "deep" (start with the cursor in the blank space before the | |
| 1131 first word). You can use the "']" or "`]" command after the put command to | |
| 1132 move the cursor to the end of the inserted text, or use "'[" or "`[" to move | |
| 1133 the cursor to the start. | |
| 1134 | |
| 1135 *put-Visual-mode* *v_p* *v_P* | |
| 1136 When using a put command like |p| or |P| in Visual mode, Vim will try to | |
| 1137 replace the selected text with the contents of the register. Whether this | |
| 1138 works well depends on the type of selection and the type of the text in the | |
| 1139 register. With blockwise selection it also depends on the size of the block | |
| 236 | 1140 and whether the corners are on an existing character. (Implementation detail: |
| 7 | 1141 it actually works by first putting the register after the selection and then |
| 236 | 1142 deleting the selection.) |

1147 unnamed register will be changed each time. |
| 7 | 1148 |
| 5365 | 1149 When you use a blockwise Visual mode command and yank only a single line into |
| 1150 a register, a paste on a visual selected area will paste that single line on | |
| 1151 each of the selected lines (thus replacing the blockwise selected region by a | |
| 1152 block of the pasted line). | |
| 1153 | |
| 7 | 1154 *blockwise-register* |
| 1155 If you use a blockwise Visual mode command to get the text into the register, | |
| 1156 the block of text will be inserted before ("P") or after ("p") the cursor | |
| 1157 column in the current and next lines. Vim makes the whole block of text start | |
| 1158 in the same column. Thus the inserted text looks the same as when it was | |
| 1159 yanked or deleted. Vim may replace some <Tab> characters with spaces to make | |
| 1160 this happen. However, if the width of the block is not a multiple of a <Tab> | |
| 1161 width and the text after the inserted block contains <Tab>s, that text may be | |
| 1162 misaligned. | |
| 1163 | |
| 1164 Note that after a characterwise yank command, Vim leaves the cursor on the | |
| 1165 first yanked character that is closest to the start of the buffer. This means | |
| 1166 that "yl" doesn't move the cursor, but "yh" moves the cursor one character | |
| 1167 left. | |
| 1168 Rationale: In Vi the "y" command followed by a backwards motion would | |
| 1169 sometimes not move the cursor to the first yanked character, | |
| 1170 because redisplaying was skipped. In Vim it always moves to | |
| 1171 the first character, as specified by Posix. | |
| 1172 With a linewise yank command the cursor is put in the first line, but the | |
| 1173 column is unmodified, thus it may not be on the first yanked character. | |
| 1174 | |
| 18186 | 1175 There are ten types of registers: *registers* *{register}* *E354* |
| 7 | 1176 1. The unnamed register "" |
| 1177 2. 10 numbered registers "0 to "9 | |
| 1178 3. The small delete register "- | |
| 1179 4. 26 named registers "a to "z or "A to "Z | |
| 17372 | 1180 5. Three read-only registers ":, "., "% |
| 1181 6. Alternate buffer register "# | |
| 1182 7. The expression register "= | |
| 6557 | 1183 8. The selection and drop registers "*, "+ and "~ |
| 1184 9. The black hole register "_ | |
| 1185 10. Last search pattern register "/ | |
| 7 | 1186 |
| 1187 1. Unnamed register "" *quote_quote* *quotequote* | |
| 1188 Vim fills this register with text deleted with the "d", "c", "s", "x" commands | |
| 1189 or copied with the yank "y" command, regardless of whether or not a specific | |
| 8 | 1190 register was used (e.g. "xdd). This is like the unnamed register is pointing |

| 7 | 1202 *quote2* *quote3* *quote4* *quote9* |
| 1203 Vim fills these registers with text from yank and delete commands. | |
| 1204 Numbered register 0 contains the text from the most recent yank command, | |
| 1205 unless the command specified another register with ["x]. | |
| 1206 Numbered register 1 contains the text deleted by the most recent delete or | |
| 1207 change command, unless the command specified another register or the text is | |
| 1208 less than one line (the small delete register is used then). An exception is | |
| 42 | 1209 made for the delete operator with these movement commands: |%|, |(|, |)|, |`|, |
| 1210 |/|, |?|, |n|, |N|, |{| and |}|. Register "1 is always used then (this is Vi | |
| 1211 compatible). The "- register is used as well if the delete is within a line. | |

1212 Note that these characters may be mapped. E.g. |%| is mapped by the matchit |

| 7 | 1214 With each successive deletion or change, Vim shifts the previous contents |
| 1215 of register 1 into register 2, 2 into 3, and so forth, losing the previous | |
| 1216 contents of register 9. | |
| 1217 {Vi: numbered register contents are lost when changing files; register 0 does | |

| 1219 | |

| 1234 ". Contains the last inserted text (the same as what is inserted | |
| 1235 with the insert mode commands CTRL-A and CTRL-@). Note: this | |
| 1236 doesn't work with CTRL-R on the command-line. It works a bit | |
| 1237 differently, like inserting the text instead of putting it | |
| 1238 ('textwidth' and other options affect what is inserted). | |

| 1242 ": Contains the most recent executed command-line. Example: Use | |
| 1243 "@:" to repeat the previous command-line command. | |

| 1245 one character of it was typed. Thus it remains unchanged if | |
| 1246 the command was completely from a mapping. | |

| 1251 Contains the name of the alternate file for the current window. It will | |
| 1252 change how the |CTRL-^| command works. | |
| 1253 This register is writable, mainly to allow for restoring it after a plugin has | |
| 1254 changed it. It accepts buffer number: > | |
| 1255 let altbuf = bufnr(@#) | |
| 1256 ... | |
| 1257 let @# = altbuf | |
| 1258 It will give error |E86| if you pass buffer number and this buffer does not | |
| 1259 exist. | |
| 1260 It can also accept a match with an existing buffer name: > | |
| 1261 let @# = 'buffer_name' | |
| 1262 Error |E93| if there is more than one buffer matching the given name or |E94| | |
| 1263 if none of buffers matches the given name. | |

| 6557 | 1265 7. Expression register "= *quote_=* *quote=* *@=* |
| 7 | 1266 This is not really a register that stores text, but is a way to use an |
| 1267 expression in commands which use a register. The expression register is | |
| 6647 | 1268 read-write. |
| 1269 | |
| 1270 When typing the '=' after " or CTRL-R the cursor moves to the command-line, | |

| 1273 expressions. When you end the command-line by typing <CR>, Vim computes the | |

| 1327 If you use a put command without specifying a register, Vim uses the register | |

| 7 | 1361 |
| 1362 *gq* | |
| 216 | 1363 gq{motion} Format the lines that {motion} moves over. |
| 667 | 1364 Formatting is done with one of three methods: |
| 1365 1. If 'formatexpr' is not empty the expression is | |
| 1366 evaluated. This can differ for each buffer. | |
| 670 | 1367 2. If 'formatprg' is not empty an external program |
| 667 | 1368 is used. |
| 843 | 1369 3. Otherwise formatting is done internally. |
| 667 | 1370 |
| 1371 In the third case the 'textwidth' option controls the | |
| 1372 length of each formatted line (see below). | |
| 216 | 1373 If the 'textwidth' option is 0, the formatted line |
| 1374 length is the screen width (with a maximum width of | |
| 667 | 1375 79). |
| 7 | 1376 The 'formatoptions' option controls the type of |
| 1377 formatting |fo-table|. | |
| 216 | 1378 The cursor is left on the first non-blank of the last |
| 1379 formatted line. | |
| 7 | 1380 NOTE: The "Q" command formerly performed this |
| 1381 function. If you still want to use "Q" for | |
| 1382 formatting, use this mapping: > | |

1404 {Visual} see |Visual-mode|). |
| 9 | 1405 |
| 7 | 1406 Example: To format the current paragraph use: *gqap* > |
| 1407 gqap | |
| 1408 | |
| 1409 The "gq" command leaves the cursor in the line where the motion command takes | |
| 1410 the cursor. This allows you to repeat formatting repeated with ".". This | |
| 1411 works well with "gqj" (format current and next line) and "gq}" (format until | |
| 1412 end of paragraph). Note: When 'formatprg' is set, "gq" leaves the cursor on | |
| 1413 the first formatted line (as with using a filter command). | |
| 1414 | |
| 1415 If you want to format the current paragraph and continue where you were, use: > | |
| 1416 gwap | |
| 1417 If you always want to keep paragraphs formatted you may want to add the 'a' | |
| 1418 flag to 'formatoptions'. See |auto-format|. | |
| 1419 | |
| 1420 If the 'autoindent' option is on, Vim uses the indent of the first line for | |
| 1421 the following lines. | |
| 1422 | |
| 1423 Formatting does not change empty lines (but it does change lines with only | |
| 1424 white space!). | |
| 1425 | |
| 1426 The 'joinspaces' option is used when lines are joined together. | |
| 1427 | |
| 667 | 1428 You can set the 'formatexpr' option to an expression or the 'formatprg' option |
| 1429 to the name of an external program for Vim to use for text formatting. The | |
| 1430 'textwidth' and other options have no effect on formatting by an external | |
| 1431 program. | |
| 7 | 1432 |
| 13912 | 1433 *format-formatexpr* |
| 14519 | 1434 The 'formatexpr' option can be set to a Vim script function that performs |
| 13912 | 1435 reformatting of the buffer. This should usually happen in an |ftplugin|, |
| 1436 since formatting is highly dependent on the type of file. It makes | |
| 1437 sense to use an |autoload| script, so the corresponding script is only loaded | |
| 1438 when actually needed and the script should be called <filetype>format.vim. | |
| 1439 | |
| 1440 For example, the XML filetype plugin distributed with Vim in the $VIMRUNTIME | |
| 1441 directory, sets the 'formatexpr' option to: > | |
| 1442 | |
| 1443 setlocal formatexpr=xmlformat#Format() | |
| 1444 | |
| 1445 That means, you will find the corresponding script, defining the | |
| 1446 xmlformat#Format() function, in the directory: | |
| 1447 `$VIMRUNTIME/autoload/xmlformat.vim` | |
| 1448 | |
| 1449 Here is an example script that removes trailing whitespace from the selected | |
| 1450 text. Put it in your autoload directory, e.g. ~/.vim/autoload/format.vim: > | |
| 1451 | |
| 1452 func! format#Format() | |
| 1453 " only reformat on explicit gq command | |
| 1454 if mode() != 'n' | |
| 1455 " fall back to Vims internal reformatting | |
| 1456 return 1 | |
| 1457 endif | |
| 1458 let lines = getline(v:lnum, v:lnum + v:count - 1) | |
| 1459 call map(lines, {key, val -> substitute(val, '\s\+$', '', 'g')}) | |
| 1460 call setline('.', lines) | |
| 1461 | |
| 1462 " do not run internal formatter! | |
| 1463 return 0 | |
| 1464 endfunc | |
| 1465 | |
| 1466 You can then enable the formatting by executing: > | |
| 1467 setlocal formatexpr=format#Format() | |
| 14519 | 1468 |
| 13912 | 1469 Note: this function explicitly returns non-zero when called from insert mode |
| 1470 (which basically means, text is inserted beyond the 'textwidth' limit). This | |
| 1471 causes Vim to fall back to reformat the text by using the internal formatter. | |
| 1472 | |
| 1473 However, if the |gq| command is used to reformat the text, the function | |
| 1474 will receive the selected lines, trim trailing whitespace from those lines and | |
| 1475 put them back in place. If you are going to split single lines into multiple | |
| 1476 lines, be careful not to overwrite anything. | |
| 1477 | |
| 1478 If you want to allow reformatting of text from insert or replace mode, one has | |
| 1479 to be very careful, because the function might be called recursively. For | |
| 1480 debugging it helps to set the 'debug' option. | |
| 1481 | |
| 7 | 1482 *right-justify* |
| 1483 There is no command in Vim to right justify text. You can do it with | |
| 1484 an external command, like "par" (e.g.: "!}par" to format until the end of the | |
| 1485 paragraph) or set 'formatprg' to "par". | |
| 1486 | |
| 1487 *format-comments* | |
| 1621 | 1488 An overview of comment formatting is in section |30.6| of the user manual. |
| 1489 | |
| 1490 Vim can automatically insert and format comments in a special way. Vim | |
| 1491 recognizes a comment by a specific string at the start of the line (ignoring | |
| 1492 white space). Three types of comments can be used: | |
| 7 | 1493 |
| 1494 - A comment string that repeats at the start of each line. An example is the | |
| 1495 type of comment used in shell scripts, starting with "#". | |
| 1496 - A comment string that occurs only in the first line, not in the following | |
| 1497 lines. An example is this list with dashes. | |
| 1498 - Three-piece comments that have a start string, an end string, and optional | |
| 1499 lines in between. The strings for the start, middle and end are different. | |
| 1621 | 1500 An example is the C style comment: |
| 7 | 1501 /* |
| 1502 * this is a C comment | |
| 1503 */ | |
| 1504 | |
| 1505 The 'comments' option is a comma-separated list of parts. Each part defines a | |
| 1506 type of comment string. A part consists of: | |
| 1507 {flags}:{string} | |
| 1508 | |
| 1509 {string} is the literal text that must appear. | |
| 1510 | |
| 1511 {flags}: | |
| 1512 n Nested comment. Nesting with mixed parts is allowed. If 'comments' | |
| 1513 is "n:),n:>" a line starting with "> ) >" is a comment. | |
| 1514 | |
| 1515 b Blank (<Space>, <Tab> or <EOL>) required after {string}. | |
| 1516 | |
| 1517 f Only the first line has the comment string. Do not repeat comment on | |
| 1518 the next line, but preserve indentation (e.g., a bullet-list). | |
| 1519 | |
| 1520 s Start of three-piece comment | |
| 1521 | |
| 1522 m Middle of a three-piece comment | |
| 1523 | |
| 1524 e End of a three-piece comment | |
| 1525 | |
| 1621 | 1526 l Left align. Used together with 's' or 'e', the leftmost character of |
| 1527 start or end will line up with the leftmost character from the middle. | |
| 1528 This is the default and can be omitted. See below for more details. | |
| 7 | 1529 |
| 1621 | 1530 r Right align. Same as above but rightmost instead of leftmost. See |
| 1531 below for more details. | |
| 7 | 1532 |
| 1621 | 1533 O Don't consider this comment for the "O" command. |
| 7 | 1534 |
| 1535 x Allows three-piece comments to be ended by just typing the last | |
| 1621 | 1536 character of the end-comment string as the first action on a new |
| 1537 line when the middle-comment string has been inserted automatically. | |
| 1538 See below for more details. | |
| 7 | 1539 |
| 1540 {digits} | |
| 1621 | 1541 When together with 's' or 'e': add {digit} amount of offset to an |
| 1542 automatically inserted middle or end comment leader. The offset begins | |
| 1543 from a left alignment. See below for more details. | |
| 7 | 1544 |
| 1545 -{digits} | |
| 1546 Like {digits} but reduce the indent. This only works when there is | |
| 1547 some indent for the start or end part that can be removed. | |
| 1548 | |
| 1549 When a string has none of the 'f', 's', 'm' or 'e' flags, Vim assumes the | |
| 1550 comment string repeats at the start of each line. The flags field may be | |
| 1551 empty. | |
| 1552 | |
| 1553 Any blank space in the text before and after the {string} is part of the | |
| 1554 {string}, so do not include leading or trailing blanks unless the blanks are a | |
| 1555 required part of the comment string. | |
| 1556 | |
| 1557 When one comment leader is part of another, specify the part after the whole. | |
| 1558 For example, to include both "-" and "->", use > | |
| 1559 :set comments=f:->,f:- | |
| 1560 | |
| 1561 A three-piece comment must always be given as start,middle,end, with no other | |
| 1562 parts in between. An example of a three-piece comment is > | |
| 1563 sr:/*,mb:*,ex:*/ | |
| 1564 for C-comments. To avoid recognizing "*ptr" as a comment, the middle string | |
| 1565 includes the 'b' flag. For three-piece comments, Vim checks the text after | |
| 1566 the start and middle strings for the end string. If Vim finds the end string, | |
| 1567 the comment does not continue on the next line. Three-piece comments must | |
| 1568 have a middle string because otherwise Vim can't recognize the middle lines. | |
| 1569 | |
| 1570 Notice the use of the "x" flag in the above three-piece comment definition. | |
| 1571 When you hit Return in a C-comment, Vim will insert the middle comment leader | |
| 1621 | 1572 for the new line: " * ". To close this comment you just have to type "/" |
| 7 | 1573 before typing anything else on the new line. This will replace the |
| 1621 | 1574 middle-comment leader with the end-comment leader and apply any specified |
| 6647 | 1575 alignment, leaving just " */". There is no need to hit Backspace first. |
| 1621 | 1576 |
| 6647 | 1577 When there is a match with a middle part, but there also is a matching end |
| 1578 part which is longer, the end part is used. This makes a C style comment work | |
| 2826 | 1579 without requiring the middle part to end with a space. |
| 1621 | 1580 |
| 1581 Here is an example of alignment flags at work to make a comment stand out | |
| 2826 | 1582 (kind of looks like a 1 too). Consider comment string: > |
| 1583 :set comments=sr:/***,m:**,ex-2:******/ | |
| 1584 < | |
| 1585 /*** ~ | |
| 1586 **<--right aligned from "r" flag ~ | |
| 1587 ** ~ | |
| 1588 offset 2 spaces for the "-2" flag--->** ~ | |
| 1589 ******/ ~ | |
| 1621 | 1590 In this case, the first comment was typed, then return was pressed 4 times, |
| 1591 then "/" was pressed to end the comment. | |
| 7 | 1592 |
| 1621 | 1593 Here are some finer points of three part comments. There are three times when |
| 1594 alignment and offset flags are taken into consideration: opening a new line | |
| 1595 after a start-comment, opening a new line before an end-comment, and | |
| 1596 automatically ending a three-piece comment. The end alignment flag has a | |
| 1597 backwards perspective; the result is that the same alignment flag used with | |
| 1598 "s" and "e" will result in the same indent for the starting and ending pieces. | |
| 1599 Only one alignment per comment part is meant to be used, but an offset number | |
| 1600 will override the "r" and "l" flag. | |
| 1601 | |
| 1602 Enabling 'cindent' will override the alignment flags in many cases. | |
| 1603 Reindenting using a different method like |gq| or |=| will not consult | |
| 1604 alignment flags either. The same behaviour can be defined in those other | |
| 1605 formatting options. One consideration is that 'cindent' has additional options | |
| 1606 for context based indenting of comments but cannot replicate many three piece | |
| 2826 | 1607 indent alignments. However, 'indentexpr' has the ability to work better with |
| 1608 three piece comments. | |
| 1621 | 1609 |
| 1610 Other examples: > | |
| 7 | 1611 "b:*" Includes lines starting with "*", but not if the "*" is |
| 1612 followed by a non-blank. This avoids a pointer dereference | |
| 1613 like "*str" to be recognized as a comment. | |
| 1614 "n:>" Includes a line starting with ">", ">>", ">>>", etc. | |
| 1615 "fb:-" Format a list that starts with "- ". | |
| 1616 | |
| 1617 By default, "b:#" is included. This means that a line that starts with | |
| 1618 "#include" is not recognized as a comment line. But a line that starts with | |
| 1619 "# define" is recognized. This is a compromise. | |
| 1620 | |
| 1621 *fo-table* | |
| 1622 You can use the 'formatoptions' option to influence how Vim formats text. | |
| 1623 'formatoptions' is a string that can contain any of the letters below. The | |
| 1624 default setting is "tcq". You can separate the option letters with commas for | |
| 1625 readability. | |
| 1626 | |
| 1627 letter meaning when present in 'formatoptions' ~ | |
| 1628 | |
| 1121 | 1629 t Auto-wrap text using textwidth |
| 7 | 1630 c Auto-wrap comments using textwidth, inserting the current comment |
| 1631 leader automatically. | |
| 1632 r Automatically insert the current comment leader after hitting | |
| 1633 <Enter> in Insert mode. | |
| 1634 o Automatically insert the current comment leader after hitting 'o' or | |
| 1635 'O' in Normal mode. | |
| 1636 q Allow formatting of comments with "gq". | |
| 1637 Note that formatting will not change blank lines or lines containing | |
| 1638 only the comment leader. A new paragraph starts after such a line, | |
| 1639 or when the comment leader changes. | |
| 1640 w Trailing white space indicates a paragraph continues in the next line. | |
| 1641 A line that ends in a non-white character ends a paragraph. | |
| 1642 a Automatic formatting of paragraphs. Every time text is inserted or | |
| 1643 deleted the paragraph will be reformatted. See |auto-format|. | |
| 1644 When the 'c' flag is present this only happens for recognized | |
| 1645 comments. | |
| 41 | 1646 n When formatting text, recognize numbered lists. This actually uses |
| 1647 the 'formatlistpat' option, thus any kind of list can be used. The | |
| 1648 indent of the text after the number is used for the next line. The | |
| 1621 | 1649 default is to find a number, optionally followed by '.', ':', ')', |
| 41 | 1650 ']' or '}'. Note that 'autoindent' must be set too. Doesn't work |
| 1651 well together with "2". | |
| 7 | 1652 Example: > |
| 1653 1. the first item | |
| 1654 wraps | |
| 1655 2. the second item | |
| 1656 2 When formatting text, use the indent of the second line of a paragraph | |
| 1657 for the rest of the paragraph, instead of the indent of the first | |
| 1658 line. This supports paragraphs in which the first line has a | |
| 1659 different indent than the rest. Note that 'autoindent' must be set | |
| 1660 too. Example: > | |
| 1661 first line of a paragraph | |
| 1662 second line of the same paragraph | |
| 1663 third line. | |
| 3682 | 1664 < This also works inside comments, ignoring the comment leader. |
| 7 | 1665 v Vi-compatible auto-wrapping in insert mode: Only break a line at a |
| 1666 blank that you have entered during the current insert command. (Note: | |
| 1667 this is not 100% Vi compatible. Vi has some "unexpected features" or | |
| 1668 bugs in this area. It uses the screen column instead of the line | |
| 1669 column.) | |
| 1670 b Like 'v', but only auto-wrap if you enter a blank at or before | |
| 1671 the wrap margin. If the line was longer than 'textwidth' when you | |
| 1672 started the insert, or you do not enter a blank in the insert before | |
| 1673 reaching 'textwidth', Vim does not perform auto-wrapping. | |
| 1674 l Long lines are not broken in insert mode: When a line was longer than | |
| 1675 'textwidth' when the insert command started, Vim does not | |

| 1703 | |
| 1704 With 't' and 'c' you can specify when Vim performs auto-wrapping: | |
| 1705 value action ~ | |
| 1706 "" no automatic formatting (you can use "gq" for manual formatting) | |
| 1707 "t" automatic formatting of text, but not comments | |
| 1708 "c" automatic formatting for comments, but not text (good for C code) | |
| 1709 "tc" automatic formatting for text and comments | |
| 1710 | |
| 867 | 1711 Note that when 'textwidth' is 0, Vim does no automatic formatting anyway (but |
| 1712 does insert comment leaders according to the 'comments' option). An exception | |
| 1713 is when the 'a' flag is present. |auto-format| | |
| 7 | 1714 |
| 1715 Note that when 'paste' is on, Vim does no formatting at all. | |
| 1716 | |
| 1717 Note that 'textwidth' can be non-zero even if Vim never performs auto-wrapping; | |
| 1718 'textwidth' is still useful for formatting with "gq". | |
| 1719 | |
| 1720 If the 'comments' option includes "/*", "*" and/or "*/", then Vim has some | |
| 1721 built in stuff to treat these types of comments a bit more cleverly. | |
| 1722 Opening a new line before or after "/*" or "*/" (with 'r' or 'o' present in | |
| 1723 'formatoptions') gives the correct start of the line automatically. The same | |
| 236 | 1724 happens with formatting and auto-wrapping. Opening a line after a line |
| 7 | 1725 starting with "/*" or "*" and containing "*/", will cause no comment leader to |
| 1726 be inserted, and the indent of the new line is taken from the line containing | |
| 1727 the start of the comment. | |
| 1728 E.g.: | |
| 1729 /* ~ | |
| 1730 * Your typical comment. ~ | |
| 1731 */ ~ | |
| 1732 The indent on this line is the same as the start of the above | |
| 1733 comment. | |
| 1734 | |
| 1735 All of this should be really cool, especially in conjunction with the new | |
| 1736 :autocmd command to prepare different settings for different types of file. | |
| 1737 | |
| 1738 Some examples: | |
| 1739 for C code (only format comments): > | |
| 1740 :set fo=croq | |
| 1741 < for Mail/news (format all, don't start comment with "o" command): > | |
| 1742 :set fo=tcrq | |
| 1743 < | |
| 1744 | |
| 3492 | 1745 Automatic formatting *auto-format* *autoformat* |
| 7 | 1746 |
| 1747 When the 'a' flag is present in 'formatoptions' text is formatted | |
| 1748 automatically when inserting text or deleting text. This works nice for | |
| 1749 editing text paragraphs. A few hints on how to use this: | |
| 1750 | |
| 1751 - You need to properly define paragraphs. The simplest is paragraphs that are | |
| 1752 separated by a blank line. When there is no separating blank line, consider | |
| 1753 using the 'w' flag and adding a space at the end of each line in the | |
| 1754 paragraphs except the last one. | |
| 1755 | |
| 1756 - You can set the 'formatoptions' based on the type of file |filetype| or | |
| 1757 specifically for one file with a |modeline|. | |
| 1758 | |
| 1759 - Set 'formatoptions' to "aw2tq" to make text with indents like this: | |
| 1760 | |
| 1761 bla bla foobar bla | |
| 1762 bla foobar bla foobar bla | |
| 1763 bla bla foobar bla | |
| 1764 bla foobar bla bla foobar | |
| 1765 | |
| 1766 - Add the 'c' flag to only auto-format comments. Useful in source code. | |
| 1767 | |
| 867 | 1768 - Set 'textwidth' to the desired width. If it is zero then 79 is used, or the |
| 1769 width of the screen if this is smaller. | |
| 1770 | |
| 7 | 1771 And a few warnings: |
| 1772 | |
| 1773 - When part of the text is not properly separated in paragraphs, making | |
| 1774 changes in this text will cause it to be formatted anyway. Consider doing > | |
| 1775 | |
| 1776 :set fo-=a | |
| 1777 | |
| 1778 - When using the 'w' flag (trailing space means paragraph continues) and | |
| 1779 deleting the last line of a paragraph with |dd|, the paragraph will be | |
| 1780 joined with the next one. | |
| 1781 | |
| 1782 - Changed text is saved for undo. Formatting is also a change. Thus each | |
| 1783 format action saves text for undo. This may consume quite a lot of memory. | |
| 1784 | |
| 1785 - Formatting a long paragraph and/or with complicated indenting may be slow. | |
| 1786 | |

| 1788 7. Sorting text *sorting* | |
| 1789 | |
| 1790 Vim has a sorting function and a sorting command. The sorting function can be | |
| 5747 | 1791 found here: |sort()|, |uniq()|. |

1828 lines will be kept in their original order. |
| 293 | 1829 Note that leading and trailing white space may cause |
| 1830 lines to be different. | |
| 282 | 1831 |
| 826 | 1832 When /{pattern}/ is specified and there is no [r] flag |
| 1833 the text matched with {pattern} is skipped, so that | |
| 1834 you sort on what comes after the match. | |
| 282 | 1835 Instead of the slash any non-letter can be used. |
| 1836 For example, to sort on the second comma-separated | |
| 1837 field: > | |
| 1838 :sort /[^,]*,/ | |
| 1839 < To sort on the text at virtual column 10 (thus | |
| 1840 ignoring the difference between tabs and spaces): > | |
| 1841 :sort /.*\%10v/ | |
| 824 | 1842 < To sort on the first number in the line, no matter |
| 1843 what is in front of it: > | |
| 1621 | 1844 :sort /.\{-}\ze\d/ |
| 1845 < (Explanation: ".\{-}" matches any text, "\ze" sets the | |
| 1846 end of the match and \d matches a digit.) | |
| 1847 With [r] sorting is done on the matching {pattern} | |
| 826 | 1848 instead of skipping past it as described above. |
| 1849 For example, to sort on only the first three letters | |
| 1850 of each line: > | |
| 1851 :sort /\a\a\a/ r | |
| 1852 | |
| 1853 < If a {pattern} is used, any lines which don't have a | |
| 1854 match for {pattern} are kept in their current order, | |
| 1855 but separate from the lines which do match {pattern}. | |
| 1856 If you sorted in reverse, they will be in reverse | |
| 1857 order after the sorted lines, otherwise they will be | |
| 1858 in their original order, right before the sorted | |
| 1859 lines. | |
| 1860 | |
| 1314 | 1861 If {pattern} is empty (e.g. // is specified), the |
| 1862 last search pattern is used. This allows trying out | |
| 1863 a pattern first. | |
| 1864 | |
| 3492 | 1865 Note that using `:sort` with `:global` doesn't sort the matching lines, it's |
| 293 | 1866 quite useless. |

1870 Vim does do a "stable" sort. |
| 359 | 1871 |
| 826 | 1872 The sorting can be interrupted, but if you interrupt it too late in the |
| 1873 process you may end up with duplicated lines. This also depends on the system | |
| 1874 library function used. | |
