7 Differences between Vim and Vi *vi-differences*
|
|
|
8
|
|
|
9 Throughout the help files differences between Vim and Vi/Ex are given in
|
|
|
10 curly braces, like "{not in Vi}". This file only lists what has not been
|
|
|
11 mentioned in other files and gives an overview.
|
|
|
12
|
|
|
13 Vim is mostly POSIX 1003.2-1 compliant. The only command known to be missing
|
|
|
14 is ":open". There are probably a lot of small differences (either because Vim
|
|
|
15 is missing something or because Posix is beside the mark).

25 ==============================================================================
|
|
166
|
26 1. Simulated command *simulated-command*
|
|
|
27
|
|
|
28 This command is in Vi, but Vim only simuates it:
|
|
|
29
|
|
|
30 *:o* *:op* *:open*
|
|
|
31 :[range]o[pen] Works like |:visual|: end Ex mode.
|
|
|
32 {Vi: start editing in open mode}
|
|
7
|
33
|
|
166
|
34 :[range]o[pen] /pattern/ As above, additionally move the cursor to the
|
|
|
35 column where "pattern" matches in the cursor
|
|
|
36 line.
|
|
7
|
37
|
|
166
|
38 Vim does not support open mode, since it's not really useful. For those
|
|
|
39 situations where ":open" would start open mode Vim will leave Ex mode, which
|
|
|
40 allows executing the same commands, but updates the whole screen instead of
|
|
|
41 only one line.
|
|

|
42
|
|
|
43 ==============================================================================
|
|
|
44 2. Missing options *missing-options*
|
|
|
45
|
|
|
46 These options are in the Unix Vi, but not in Vim. If you try to set one of
|
|
|
47 them you won't get an error message, but the value is not used and cannot be
|
|
|
48 printed.
|
|
|
49
|
|
|
50 autoprint (ap) boolean (default on) *'autoprint'* *'ap'*
|
|
|
51 beautify (bf) boolean (default off) *'beautify'* *'bf'*
|
|
|
52 flash (fl) boolean (default ??) *'flash'* *'fl'*
|
|
|
53 graphic (gr) boolean (default off) *'graphic'* *'gr'*
|
|
|
54 hardtabs (ht) number (default 8) *'hardtabs'* *'ht'*
|
|
|
55 number of spaces that a <Tab> moves on the display
|
|
|
56 mesg boolean (default on) *'mesg'*
|
|
|
57 novice boolean (default off) *'novice'*
|
|
|
58 open boolean (default on) *'open'*
|
|
|
59 optimize (op) boolean (default off) *'optimize'* *'op'*
|
|
|
60 redraw boolean (default off) *'redraw'*
|
|
|
61 slowopen (slow) boolean (default off) *'slowopen'* *'slow'*
|
|
|
62 sourceany boolean (default off) *'sourceany'*
|
|
|
63 w300 number (default 23) *'w300'*
|
|
|
64 w1200 number (default 23) *'w1200'*
|
|
|
65 w9600 number (default 23) *'w9600'*
|
|
|

|
67 ==============================================================================
|
|
|
68 3. Limits *limits*
|
|
|
69
|
|
|
70 Vim has only a few limits for the files that can be edited {Vi: can not handle
|
|
|
71 <Nul> characters and characters above 128, has limited line length, many other
|
|
|
72 limits}.
|
|
|
73 *E340*
|
|
|
74 Maximum line length On machines with 16-bit ints (Amiga and MS-DOS real
|
|
|
75 mode): 32767, otherwise 2147483647 characters.
|
|
|
76 Longer lines are split.
|
|
|
77 Maximum number of lines 2147483647 lines.
|
|
|
78 Maximum file size 2147483647 bytes (2 Gbyte) when a long integer is
|
|
|
79 32 bits. Much more for 64 bit longs. Also limited
|
|
|
80 by available disk space for the |swap-file|.
|
|
|
81 *E75*
|
|
|
82 Length of a file path Unix and Win32: 1024 characters, otherwise 256
|
|
|
83 characters (or as much as the system supports).
|
|
|
84 Length of an expanded string option
|
|
|
85 Unix and Win32: 1024 characters, otherwise 256
|
|
|
86 characters
|
|
|
87 Maximum display width Unix and Win32: 1024 characters, otherwise 255
|
|
|
88 characters
|
|
|
89 Maximum lhs of a mapping 50 characters.
|
|
|
90 Number of highlighting different types: 223
|
|
|
91
|
|
|
92 Information for undo and text in registers is kept in memory, thus when making
|
|
|
93 (big) changes the amount of (virtual) memory available limits the number of
|
|
|
94 undo levels and the text that can be kept in registers. Other things are also
|
|
|
95 kept in memory: Command-line history, error messages for Quickfix mode, etc.
|
|
|
96
|
|
|
97 Memory usage limits
|
|
|
98 -------------------
|
|
|
99
|
|
|
100 The option 'maxmem' ('mm') is used to set the maximum memory used for one
|
|
|
101 buffer (in kilobytes). 'maxmemtot' is used to set the maximum memory used for
|
|
|
102 all buffers (in kilobytes). The defaults depend on the system used. For the
|
|
|
103 Amiga and MS-DOS, 'maxmemtot' is set depending on the amount of memory
|
|
|
104 available. If you don't like Vim to swap to a file, set 'maxmem' and
|
|
|
105 'maxmemtot' to a very large value. The swap file will then only be used for
|
|
|
106 recovery. If you don't want a swap file at all, set 'updatecount' to 0, or
|
|
|
107 use the "-n" argument when starting Vim. Note that the 'maxmem' option is
|
|
|
108 only used when a buffer is created. Changing this option does not affect
|
|
|
109 buffers that have already been loaded. Thus you can set it to different
|
|
|
110 values for different files. 'maxmemtot' works always.
|
|
|

112 ==============================================================================
|
|
|
113 4. The most interesting additions *vim-additions*
|
|
|
114
|
|
|
115 Vi compatibility. |'compatible'|
|
|
|
116 Although Vim is 99% Vi compatible, some things in Vi can be
|
|
|
117 considered to be a bug, or at least need improvement. But still, Vim
|
|
|
118 starts in a mode which behaves like the "real" Vi as much as possible.
|
|
|
119 To make Vim behave a little bit better, try resetting the 'compatible'
|
|
|
120 option:
|
|
|
121 :set nocompatible
|
|
|
122 Or start Vim with the "-N" argument:
|
|
|
123 vim -N
|
|
|
124 This is done automatically if you have a .vimrc file. See |startup|.
|
|
|
125 The 'cpoptions' option can be used to set Vi compatibility on/off for
|
|
|
126 a number of specific items.
|
|
|
127
|
|
|
128 Support for different systems.
|
|
|
129 Vim can be used on:
|
|
|
130 - All Unix systems (it works on all systems it was tested on, although
|
|
|
131 the GUI and Perl interface may not work everywhere).
|
|
|
132 - Amiga (500, 1000, 1200, 2000, 3000, 4000, ...).
|
|
|
133 - MS-DOS in real-mode (no additional drivers required).
|
|
|
134 - In protected mode on Windows 3.1 and MS-DOS (DPMI driver required).
|
|
|
135 - Windows 95 and Windows NT, with support for long file names.
|
|
|
136 - OS/2 (needs emx.dll)
|
|
|
137 - Atari MiNT
|
|
|
138 - VMS
|
|
|
139 - BeOS
|
|
|
140 - Macintosh
|
|
|
141 - Risc OS
|
|
|
142 - IBM OS/390
|
|
|
143
|
|
|
144 Multi level undo. |undo|
|
|
|
145 'u' goes backward in time, 'CTRL-R' goes forward again. Set option
|
|
|
146 'undolevels' to the number of changes to be remembered (default 1000).
|
|
235
|
147 Set 'undolevels' to 0 for a vi-compatible one level undo. Set it to
|
|
7
|
148 -1 for no undo at all.
|
|
|
149
|
|
|
150 When all changes in a buffer have been undone, the buffer is not
|
|
|
151 considered changed anymore. You can exit it with :q, without <!>.
|
|
|
152
|
|
|
153 Graphical User Interface (GUI) |gui|
|
|
|
154 Included support for GUI: menu's, mouse, scrollbars, etc. You can
|
|
|
155 define your own menus. Better support for CTRL/SHIFT/ALT keys in
|
|
|
156 combination with special keys and mouse. Supported for various
|
|
|
157 platforms, such as X11 (with Motif and Athena interfaces), GTK, Win32
|
|
|
158 (Windows 95 and later), BeOS, Amiga and Macintosh.
|
|
|
159
|
|
|
160 Multiple windows and buffers. |windows.txt|
|
|
|
161 Vim can split the screen into several windows, each editing a
|
|
|
162 different buffer or the same buffer at a different location. Buffers
|
|
|
163 can still be loaded (and changed) but not displayed in a window. This
|
|
|
164 is called a hidden buffer. Many commands and options have been added
|
|
|
165 for this facility.
|
|
|
166
|
|
|
167 Syntax highlighting. |:syntax|
|
|
|
168 Vim can highlight keywords, patterns and other things. This is
|
|
|
169 defined by a number of ":syntax" commands, and can be made to
|
|
|
170 highlight most languages and file types. A number of files are
|
|
|
171 included for highlighting the most common languages, like C, C++,
|
|
|
172 Java, Pascal, Makefiles, shell scripts, etc. The colors used for
|
|
|
173 highlighting can be defined for ordinary terminals, color terminals
|
|
|
174 and the GUI with the ":highlight" command.
|
|
|
175
|
|
|
176 Folding |folding|
|
|
|
177 A range of lines can be shown as one "folded" line. This allows
|
|
|
178 overviewing a file and moving blocks of text around quickly.
|
|
|
179 Folds can be created manually, from the syntax of the file, by indent,
|
|
|
180 etc.
|
|
|
181
|
|
|
182 Plugins |add-plugin|
|
|
|
183 The functionality can be extended by dropping a plugin file in the
|
|
|
184 right directory. That's an easy way to start using Vim scripts
|
|
|
185 written by others. Plugins can be for all kind of files, or
|
|
|
186 specifically for a filetype.
|
|
|
187
|
|
|
188 Repeat a series of commands. |q|
|
|
|
189 "q{c}" starts recording typed characters into named register {c}
|
|
|
190 (append to the register if register name is uppercase). A subsequent
|
|
|
191 "q" stops recording. The register can then be executed with the
|
|
|
192 "@{c}" command. This is very useful to repeat a complex action.
|
|
|
193
|
|
|
194 Flexible insert mode. |ins-special-special|
|
|
|
195 The arrow keys can be used in insert mode to move around in the file.
|
|
|
196 This breaks the insert in two parts as far as undo and redo is
|
|
|
197 concerned.
|
|
|
198
|
|
|
199 CTRL-O can be used to execute a single command-mode command. This is
|
|
|
200 almost the same as hitting <Esc>, typing the command and doing "a".
|
|
|
201
|
|
|
202 Visual mode. |Visual-mode|
|
|
|
203 Visual can be used to first highlight a piece of text and then give a
|
|
|
204 command to do something with it. This is an (easy to use) alternative
|
|
|
205 to first giving the operator and then moving to the end of the text
|
|
|
206 to be operated upon. "v" and "V" are used to start Visual mode. "v"
|
|
|
207 works on characters and 'V' on lines. Move the cursor to extend the
|
|
|
208 Visual part. It is shown highlighted on the screen. By typing "o"
|
|
|
209 the other end of the Visual text can be moved. The Visual text can
|
|
|
210 be affected by an operator:
|
|
|
211 d delete
|
|
|
212 c change
|
|
|
213 y yank
|
|
|
214 > or < insert or delete indent
|
|
|
215 ! filter through external program
|
|
|
216 = filter through indent
|
|
|
217 : start ":" command for the Visual lines.
|
|
|
218 gq format text to 'textwidth' columns
|
|
|
219 J join lines
|
|
|
220 ~ swap case
|
|
|
221 u make lowercase
|
|
|
222 U make uppercase
|
|
|
223
|
|
|
224 Block operators. |visual-block|
|
|
|
225 With Visual a rectangular block of text can be selected. Start Visual
|
|
|
226 with CTRL-V. The block can be deleted ("d"), yanked ("y") or its case
|
|
|
227 can be changed ("~", "u" and "U"). A deleted or yanked block can be
|
|
|
228 put into the text with the "p" and "P" commands.
|
|
|
229
|
|
|
230 Online help system. |:help|
|
|
|
231 Help is displayed in a window. The usual commands can be used to
|
|
|
232 move around, search for a string, etc. Tags can be used to jump
|
|
|
233 around in the help files, just like hypertext links. The ":help"
|
|
|
234 command takes an argument to quickly jump to the info on a subject.
|
|
|
235 <F1> is the quick access to the help system. The name of the help
|
|
|
236 index file can be set with the 'helpfile' option.
|
|
|
237
|
|
|
238 Command-line editing and history. |cmdline-editing|
|
|
|
239 You can insert or delete at any place in the command-line using the
|
|
|
240 cursor keys. The right/left cursor keys can be used to move
|
|
|
241 forward/backward one character. The shifted right/left cursor keys
|
|
|
242 can be used to move forward/backward one word. CTRL-B/CTRL-E can be
|
|
|
243 used to go to the begin/end of the command-line.
|
|
|
244
|
|
|
245 |cmdline-history|
|
|
|
246 The command-lines are remembered. The up/down cursor keys can be used
|
|
|
247 to recall previous command-lines. The 'history' option can be set to
|
|
|
248 the number of lines that will be remembered. There is a separate
|
|
|
249 history for commands and for search patterns.
|
|
|
250
|
|
|
251 Command-line completion. |cmdline-completion|
|
|
|
252 While entering a command-line (on the bottom line of the screen)
|
|
|
253 <Tab> can be typed to complete
|
|
|
254 what example ~
|
|
|
255 - command :e<Tab>
|
|
|
256 - tag :ta scr<Tab>
|
|
|
257 - option :set sc<Tab>
|
|
|
258 - option value :set hf=<Tab>
|
|
|
259 - file name :e ve<Tab>
|
|
|
260 - etc.
|
|
|
261
|
|
|
262 If there are multiple matches, CTRL-N (next) and CTRL-P (previous)
|
|
|
263 will walk through the matches. <Tab> works like CTRL-N, but wraps
|
|
|
264 around to the first match.
|
|
|
265
|
|
|
266 The 'wildchar' option can be set to the character for command-line
|
|
|
267 completion, <Tab> is the default. CTRL-D can be typed after an
|
|
|
268 (incomplete) wildcard; all matches will be listed. CTRL-A will insert
|
|
|
269 all matches. CTRL-L will insert the longest common part of the
|
|
|
270 matches.
|
|
|
271
|
|
|
272 Insert-mode completion |ins-completion|
|
|
|
273 In insert mode the CTRL-N and CTRL-P keys can be used to complete a
|
|
|
274 word that has previously been used. |i_CTRL-N|
|
|
|
275 With CTRL-X another mode is entered, through which completion can be
|
|
|
276 done for:
|
|
|
277 |i_CTRL-X_CTRL-F| file names
|
|
|
278 |i_CTRL-X_CTRL-K| words from 'dictionary' files
|
|
|
279 |i_CTRL-X_CTRL-T| words from 'thesaurus' files
|
|
|
280 |i_CTRL-X_CTRL-I| words from included files
|
|
|
281 |i_CTRL-X_CTRL-L| whole lines
|
|
|
282 |i_CTRL-X_CTRL-]| words from the tags file
|
|
|
283 |i_CTRL-X_CTRL-D| definitions or macros
|
|
|
284
|
|
|
285 Long line support |'wrap'| |'linebreak'|
|
|
|
286 If the 'wrap' option is off, long lines will not wrap and only part
|
|
|
287 of them will be shown. When the cursor is moved to a part that is not
|
|
|
288 shown, the screen will scroll horizontally. The minimum number of
|
|
|
289 columns to scroll can be set with the 'sidescroll' option. The "zh"
|
|
|
290 and "zl" commands can be used to scroll sideways.
|
|
|
291 Alternatively, long lines are broken in between words when the
|
|
|
292 'linebreak' option is set. This allows editing a single-line
|
|
|
293 paragraph conveniently (e.g. when the text is later read into a DTP
|
|
|
294 program). Move the cursor up/down with the "gk" and "gj" commands.
|
|
|
295
|
|
|
296 Text formatting. |formatting|
|
|
|
297 The 'textwidth' option can be used to automatically limit the line
|
|
|
298 length. This supplements the 'wrapmargin' option of Vi, which was not
|
|
|
299 very useful. The "gq" operator can be used to format a piece of text
|
|
|
300 (for example, "gqap" formats the current paragraph). Commands for
|
|
|
301 text alignment: ":center", ":left" and ":right".
|
|
|
302
|
|
|
303 Extended search patterns |pattern|
|
|
|
304 There are many extra items to match various text items. Examples:
|
|
|
305 A "\n" can be used in a search pattern to match a line break.
|
|
|
306 "x\{2,4}" matches "x" 2 to 4 times.
|
|
|
307 "\s" matches a white space character.
|
|
|
308
|
|
|
309 Edit-compile-edit speedup. |quickfix|
|
|
|
310 The ":make" command can be used to run the compilation and jump to
|
|
|
311 the first error. Alternatively Vim can be started with the "-q"
|
|
|
312 option from the compiler. A file with compiler error messages is
|
|
|
313 interpreted. Vim starts editing at the first error.
|
|
|
314
|
|
|
315 Each line in the error file is scanned for the name of a file, line
|
|
|
316 number and error message. The 'errorformat' option can be set to a
|
|
|
317 list of scanf-like strings to handle output from many compilers.
|
|
|
318
|
|
|
319 The ":cn" command can be used to jump to the next error.
|
|
|
320 ":cl" lists all the error messages. Other commands are available
|
|
|
321 (almost the same as with Manx's Z editor on the Amiga).
|
|
|
322 The 'makeef' option has the name of the file with error messages.
|
|
|
323 The 'makeprg' option contains the name of the program to be executed
|
|
|
324 with the ":make" command.
|
|
|
325 The 'shellpipe' option contains the string to be used to put the
|
|
|
326 output of the compiler into the errorfile.
|
|
|
327
|
|
|
328 Improved indenting for C programs |'cindent'|
|
|
|
329 When the 'cindent' option is on the indent of each line is
|
|
|
330 automatically adjusted. C syntax is mostly recognized. The indent
|
|
|
331 for various styles can be set with 'cinoptions'. The keys to trigger
|
|
|
332 indenting can be set with 'cinkeys'.
|
|
|
333
|
|
|
334 Comments can be automatically formatted. The 'comments' option can be
|
|
|
335 set to the characters that start and end a comment. This works best
|
|
|
336 for C code, but also works for e-mail (">" at start of the line) and
|
|
|
337 other types of text. The "=" operator can be used to re-indent
|
|
|
338 lines.
|
|
|
339
|
|
|
340 Searching for words in include files |include-search|
|
|
|
341 The "[i" command can be used to search for a match of the word under
|
|
|
342 the cursor in the current and included files. The 'include' option
|
|
|
343 can be set the a pattern that describes a command to include a file
|
|
|
344 (the default is for C programs).
|
|
|
345 The "[I" command lists all matches, the "[ CTRL-I" command jumps to
|
|
|
346 a match.
|
|
|
347 The "[d", "[D" and "[ CTRL-D" commands do the same, but only for
|
|
|
348 lines where the pattern given with the 'define' option matches.
|
|
|
349
|
|
|
350 Automatic commands |autocommand|
|
|
|
351 Commands can be automatically executed when reading a file, writing a
|
|
|
352 file, jumping to another buffer, etc., depending on the file name.
|
|
|
353 This is useful to set options and mappings for C programs,
|
|
|
354 documentation, plain text, e-mail, etc. This also makes it possible
|
|
|
355 to edit compressed files.
|
|
|
356
|
|
|
357 Scripts and Expressions |expression|
|
|
|
358 Commands have been added to form up a simple but powerful script
|
|
|
359 language.
|
|
|
360 |:if| Conditional execution, which can be used for example
|
|
|
361 to set options depending on the value of $TERM.
|
|
|
362 |:while| Repeat a number of commands.
|
|
|
363 |:echo| Print the result of an expression.
|
|
|
364 |:let| Assign a value to an internal variable, option, etc.
|
|
|
365 |:execute| Execute a command formed by an expression.
|
|
|
366 etc.
|
|
|
367
|
|
|
368 Viminfo |viminfo-file|
|
|
|
369 The command-line history, marks and registers can be stored in a file
|
|
|
370 that is read on startup. This can be used to repeat a search command
|
|
|
371 or command-line command after exiting and restarting Vim. It is also
|
|
|
372 possible to jump right back to where the last edit stopped with "'0".
|
|
|
373 The 'viminfo' option can be set to select which items to store in the
|
|
|
374 .viminfo file. This is off by default.
|
|
|
375
|
|
|
376 Mouse support |mouse-using|
|
|
|
377 The mouse is supported in the GUI version, in an xterm for Unix, for
|
|
|
378 Linux with gpm, for MS-DOS, and Win32. It can be used to position the
|
|
|
379 cursor, select the visual area, paste a register, etc.
|
|
|
380
|
|
|
381 Usage of key names |<>| |key-notation|
|
|
|
382 Special keys now all have a name like <Up>, <End>, etc.
|
|
|
383 This name can be used in mappings, to make it easy to edit them.
|
|
|
384
|
|
|
385 Editing binary files |edit-binary|
|
|
|
386 Vim can edit binary files. You can change a few characters in an
|
|
|
387 executable file, without corrupting it. Vim doesn't remove NUL
|
|
|
388 characters (they are represented as <NL> internally).
|
|
|
389 |-b| command-line argument to start editing a binary file
|
|
|
390 |'binary'| Option set by "-b". Prevents adding an <EOL> for the
|
|
|
391 last line in the file.
|
|
|
392
|
|
|
393 Multi-language support |multi-lang|
|
|
|
394 Files in double-byte or multi-byte encodings can be edited. There is
|
|
|
395 UTF-8 support to be able to edit various languages at the same time,
|
|
|
396 without switching fonts. |UTF-8|
|
|
|
397 Messages and menus are available in different languages.

|
400 5. Other vim features *other-features*
|
|
|
401
|
|
|
402 A random collection of nice extra features.
|
|
|
403
|
|
|
404
|
|
|
405 When Vim is started with "-s scriptfile", the characters read from
|
|
|
406 "scriptfile" are treated as if you typed them. If end of file is reached
|
|
|
407 before the editor exits, further characters are read from the console.
|
|
|
408
|
|
|
409 The "-w" option can be used to record all typed characters in a script file.
|
|
|
410 This file can then be used to redo the editing, possibly on another file or
|
|
|
411 after changing some commands in the script file.
|
|
|
412
|
|
|
413 The "-o" option opens a window for each argument. "-o4" opens four windows.
|
|
|
414
|
|
|
415 Vi requires several termcap entries to be able to work full-screen. Vim only
|
|
|
416 requires the "cm" entry (cursor motion).
|
|
|
417
|
|
|
418
|
|
|
419 In command mode:
|
|
|
420
|
|
|
421 When the 'showcmd' option is set, the command characters are shown in the last
|
|
|
422 line of the screen. They are removed when the command is finished.
|
|
|
423
|
|
|
424 If the 'ruler' option is set, the current cursor position is shown in the
|
|
|
425 last line of the screen.
|
|
|
426
|
|
|
427 "U" still works after having moved off the last changed line and after "u".
|
|
|
428
|
|
|
429 Characters with the 8th bit set are displayed. The characters between '~' and
|
|
|
430 0xa0 are displayed as "~?", "~@", "~A", etc., unless they are included in the
|
|
|
431 'isprint' option.
|
|
|
432
|
|
|
433 "][" goes to the next ending of a C function ('}' in column 1).
|
|
|
434 "[]" goes to the previous ending of a C function ('}' in column 1).
|
|
|
435
|
|
|
436 "]f", "[f" and "gf" start editing the file whose name is under the cursor.
|
|
|
437 CTRL-W f splits the window and starts editing the file whose name is under
|
|
|
438 the cursor.
|
|
|
439
|
|
|
440 "*" searches forward for the identifier under the cursor, "#" backward.
|
|
|
441 "K" runs the program defined by the 'keywordprg' option, with the identifier
|
|
|
442 under the cursor as argument.
|
|
|
443
|
|
|
444 "%" can be preceded with a count. The cursor jumps to the line that
|
|
|
445 percentage down in the file. The normal "%" function to jump to the matching
|
|
|
446 brace skips braces inside quotes.
|
|
|
447
|
|
|
448 With the CTRL-] command, the cursor may be in the middle of the identifier.
|
|
|
449
|
|
|
450 The used tags are remembered. Commands that can be used with the tag stack
|
|
|
451 are CTRL-T, ":pop" and ":tag". ":tags" lists the tag stack.
|
|
|
452
|
|
|
453 The 'tags' option can be set to a list of tag file names. Thus multiple
|
|
|
454 tag files can be used. For file names that start with "./", the "./" is
|
|
|
455 replaced with the path of the current file. This makes it possible to use a
|
|
|
456 tags file in the same directory as the file being edited.
|
|
|
457
|
|
|
458 Previously used file names are remembered in the alternate file name list.
|
|
|
459 CTRL-^ accepts a count, which is an index in this list.
|
|
|
460 ":files" command shows the list of alternate file names.
|
|
|
461 "#<N>" is replaced with the <N>th alternate file name in the list.
|
|
|
462 "#<" is replaced with the current file name without extension.
|
|
|
463
|
|
|
464 Search patterns have more features. The <NL> character is seen as part of the
|
|
|
465 search pattern and the substitute string of ":s". Vi sees it as the end of
|
|
|
466 the command.
|
|
|
467
|
|
|
468 Searches can put the cursor on the end of a match and may include a character
|
|
|
469 offset.
|
|
|
470
|
|
|
471 Count added to "~", ":next", ":Next", "n" and "N".
|
|
|
472
|
|
|
473 The command ":next!" with 'autowrite' set does not write the file. In vi the
|
|
|
474 file was written, but this is considered to be a bug, because one does not
|
|
|
475 expect it and the file is not written with ":rewind!".
|
|
|
476
|
|
|
477 In Vi when entering a <CR> in replace mode deletes a character only when 'ai'
|
|
|
478 is set (but does not show it until you hit <Esc>). Vim always deletes a
|
|
|
479 character (and shows it immediately).
|
|
|
480
|
|
|
481 Added :wnext command. Same as ":write" followed by ":next".
|
|
|
482
|
|
|
483 The ":w!" command always writes, also when the file is write protected. In Vi
|
|
|
484 you would have to do ":!chmod +w %" and ":set noro".
|
|
|
485
|
|
|
486 When 'tildeop' has been set, "~" is an operator (must be followed by a
|
|
|
487 movement command).
|
|
|
488
|
|
|
489 With the "J" (join) command you can reset the 'joinspaces' option to have only
|
|
|
490 one space after a period (Vi inserts two spaces).
|
|
|
491
|
|
|
492 "cw" can be used to change white space formed by several characters (Vi is
|
|
|
493 confusing: "cw" only changes one space, while "dw" deletes all white space).
|
|
|
494
|
|
|
495 "o" and "O" accept a count for repeating the insert (Vi clears a part of
|
|
|
496 display).
|
|
|
497
|
|
|
498 Flags after Ex commands not supported (no plans to include it).
|
|
|
499
|
|
|
500 On non-UNIX systems ":cd" command shows current directory instead of going to
|
|
|
501 the home directory (there isn't one). ":pwd" prints the current directory on
|
|
|
502 all systems.
|
|
|
503
|
|
|
504 After a ":cd" command the file names (in the argument list, opened files)
|
|
|
505 still point to the same files. In Vi ":cd" is not allowed in a changed file;
|
|
|
506 otherwise the meaning of file names change.
|
|
|
507
|
|
|
508 ":source!" command reads Vi commands from a file.
|
|
|
509
|
|
|
510 ":mkexrc" command writes current modified options and mappings to a ".exrc"
|
|
|
511 file. ":mkvimrc" writes to a ".vimrc" file.
|
|
|
512
|
|
|
513 No check for "tail recursion" with mappings. This allows things like
|
|
|
514 ":map! foo ^]foo".
|
|
|
515
|
|
|
516 When a mapping starts with number, vi loses the count typed before it (e.g.
|
|
|
517 when using the mapping ":map g 4G" the command "7g" goes to line 4). This is
|
|
|
518 considered a vi bug. Vim concatenates the counts (in the example it becomes
|
|
|
519 "74G"), as most people would expect.
|
|
|
520
|
|
|
521 The :put! command inserts the contents of a register above the current line.
|
|
|
522
|
|
|
523 The "p" and "P" commands of vi cannot be repeated with "." when the putted
|
|
|
524 text is less than a line. In Vim they can always be repeated.
|
|
|
525
|
|
|
526 ":noremap" command can be used to enter a mapping that will not be remapped.
|
|
|
527 This is useful to exchange the meaning of two keys. ":cmap", ":cunmap" and
|
|
|
528 ":cnoremap" can be used for mapping in command-line editing only. ":imap",
|
|
|
529 ":iunmap" and ":inoremap" can be used for mapping in insert mode only.
|
|
|
530 Similar commands exist for abbreviations: ":noreabbrev", ":iabbrev"
|
|
|
531 ":cabbrev", ":iunabbrev", ":cunabbrev", ":inoreabbrev", ":cnoreabbrev".
|
|
|
532
|
|
|
533 In Vi the command ":map foo bar" would remove a previous mapping
|
|
|
534 ":map bug foo". This is considered a bug, so it is not included in Vim.
|
|
|
535 ":unmap! foo" does remove ":map! bug foo", because unmapping would be very
|
|
|
536 difficult otherwise (this is vi compatible).
|
|
|
537
|
|
|
538 The ':' register contains the last command-line.
|
|
|
539 The '%' register contains the current file name.
|
|
|
540 The '.' register contains the last inserted text.
|
|
|
541
|
|
|
542 ":dis" command shows the contents of the yank registers.
|
|
|
543
|
|
|
544 CTRL-O/CTRL-I can be used to jump to older/newer positions. These are the
|
|
|
545 same positions as used with the '' command, but may be in another file. The
|
|
|
546 ":jumps" command lists the older positions.
|
|
|
547
|
|
|
548 If the 'shiftround' option is set, an indent is rounded to a multiple of
|
|
|
549 'shiftwidth' with ">" and "<" commands.
|
|
|
550
|
|
|
551 The 'scrolljump' option can be set to the minimum number of lines to scroll
|
|
|
552 when the cursor gets off the screen. Use this when scrolling is slow.
|
|
|
553
|
|
|
554 The 'scrolloff' option can be set to the minimum number of lines to keep
|
|
|
555 above and below the cursor. This gives some context to where you are
|
|
|
556 editing. When set to a large number the cursor line is always in the middle
|
|
|
557 of the window.
|
|
|
558
|
|
|
559 Uppercase marks can be used to jump between files. The ":marks" command lists
|
|
|
560 all currently set marks. The commands "']" and "`]" jump to the end of the
|
|
|
561 previous operator or end of the text inserted with the put command. "'[" and
|
|
|
562 "`[" do jump to the start.
|
|
|
563
|
|
|
564 The 'shelltype' option can be set to reflect the type of shell used on the
|
|
|
565 Amiga.
|
|
|
566
|
|
|
567 The 'highlight' option can be set for the highlight mode to be used for
|
|
|
568 several commands.
|
|
|
569
|
|
|
570 The CTRL-A (add) and CTRL-X (subtract) commands are new. The count to the
|
|
|
571 command (default 1) is added to/subtracted from the number at or after the
|
|
|
572 cursor. That number may be decimal, octal (starts with a '0') or hexadecimal
|
|
|
573 (starts with '0x'). Very useful in macros.
|
|
|
574
|
|
|
575 With the :set command the prefix "inv" can be used to invert boolean options.
|
|
|
576
|
|
|
577 In both Vi and Vim you can create a line break with the ":substitute" command
|
|
|
578 by using a CTRL-M. For Vi this means you cannot insert a real CTRL-M in the
|
|
|
579 text. With Vim you can put a real CTRL-M in the text by preceding it with a
|
|
|
580 CTRL-V.
|
|
|
581
|
|
|
582
|
|
|
583 In Insert mode:
|
|
|
584
|
|
|
585 If the 'revins' option is set, insert happens backwards. This is for typing
|
|
|
586 Hebrew. When inserting normal characters the cursor will not be shifted and
|
|
|
587 the text moves rightwards. Backspace, CTRL-W and CTRL-U will also work in
|
|
|
588 the opposite direction. CTRL-B toggles the 'revins' option. In replace mode
|
|
|
589 'revins' has no effect. Only when enabled at compile time.
|
|
|
590
|
|
|
591 The backspace key can be used just like CTRL-D to remove auto-indents.
|
|
|
592
|
|
|
593 You can backspace, CTRL-U and CTRL-W over line breaks if the 'backspace' (bs)
|
|
|
594 option includes "eol". You can backspace over the start of insert if the
|
|
|
595 'backspace' option includes "start".
|
|
|
596
|
|
|
597 When the 'paste' option is set, a few option are reset and mapping in insert
|
|
|
598 mode and abbreviation are disabled. This allows for pasting text in windowing
|
|
|
599 systems without unexpected results. When the 'paste' option is reset, the old
|
|
|
600 option values are restored.
|
|
|
601
|
|
|
602 CTRL-T/CTRL-D always insert/delete an indent in the current line, no matter
|
|
|
603 what column the cursor is in.
|
|
|
604
|
|
|
605 CTRL-@ (insert previously inserted text) works always (Vi: only when typed as
|
|
|
606 first character).
|
|
|
607
|
|
|
608 CTRL-A works like CTRL-@ but does not leave insert mode.
|
|
|
609
|
|
|
610 CTRL-R {0-9a-z..} can be used to insert the contents of a register.
|
|
|
611
|
|
|
612 When the 'smartindent' option is set, C programs will be better auto-indented.
|
|
|
613 With 'cindent' even more.
|
|
|
614
|
|
|
615 CTRL-Y and CTRL-E can be used to copy a character from above/below the
|
|
|
616 current cursor position.
|
|
|
617
|
|
|
618 After CTRL-V you can enter a three digit decimal number. This byte value is
|
|
|
619 inserted in the text as a single character. Useful for international
|
|
|
620 characters that are not on your keyboard.
|
|
|
621
|
|
|
622 When the 'expandtab' (et) option is set, a <Tab> is expanded to the
|
|
|
623 appropriate number of spaces.
|
|
|
624
|
|
|
625 The window always reflects the contents of the buffer (Vi does not do this
|
|
|
626 when changing text and in some other cases).
|
|
|
627
|
|
|
628 If Vim is compiled with DIGRAPHS defined, digraphs are supported. A set of
|
|
|
629 normal digraphs is included. They are shown with the ":digraph" command.
|
|
|
630 More can be added with ":digraph {char1}{char2} {number}". A digraph is
|
|
|
631 entered with "CTRL-K {char1} {char2}" or "{char1} BS {char2}" (only when
|
|
|
632 'digraph' option is set).
|
|
|
633
|
|
|
634 When repeating an insert, e.g. "10atest <Esc>" vi would only handle wrapmargin
|
|
|
635 for the first insert. Vim does it for all.
|
|
|
636
|
|
|
637 A count to the "i" or "a" command is used for all the text. Vi uses the count
|
|
|
638 only for one line. "3iabc<NL>def<Esc>" would insert "abcabcabc<NL>def" in Vi
|
|
|
639 but "abc<NL>defabc<NL>defabc<NL>def" in Vim.
|
|
|
640
|
|
|
641
|
|
|
642 In Command-line mode:
|
|
|
643

644 <Esc> terminates the command-line without executing it. In vi the command
|
|
7
|
645 line would be executed, which is not what most people expect (hitting <Esc>
|
|
|
646 should always get you back to command mode). To avoid problems with some
|
|
|
647 obscure macros, an <Esc> in a macro will execute the command. If you want a
|
|
|
648 typed <Esc> to execute the command like vi does you can fix this with
|
|
|
649 ":cmap ^V<Esc> ^V<CR>"
|
|
|
650
|
|
|
651 General:
|
|
|
652
|
|
|
653 The 'ttimeout' option is like 'timeout', but only works for cursor and
|
|
|
654 function keys, not for ordinary mapped characters. The 'timeoutlen' option
|
|
|
655 gives the number of milliseconds that is waited for. If the 'esckeys' option
|
|
|
656 is not set, cursor and function keys that start with <Esc> are not recognized
|
|
|
657 in insert mode.
|
|
|
658
|
|
|
659 There is an option for each terminal string. Can be used when termcap is not
|
|
|
660 supported or to change individual strings.
|
|
|
661
|
|
|
662 The 'fileformat' option can be set to select the <EOL>: "dos" <CR><NL>, "unix"
|
|
|
663 <NL> or "mac" <CR>.
|
|
|
664 When the 'fileformats' option is not empty, Vim tries to detect the type of
|
|
|
665 <EOL> automatically. The 'fileformat' option is set accordingly.
|
|
|
666
|
|
|
667 On systems that have no job control (older Unix systems and non-Unix systems)
|
|
|
668 the CTRL-Z, ":stop" or ":suspend" command starts a new shell.
|
|
|
669
|
|
|
670 If Vim is started on the Amiga without an interactive window for output, a
|
|
|
671 window is opened (and :sh still works). You can give a device to use for
|
|
|
672 editing with the |-d| argument, e.g. "-d con:20/20/600/150".
|
|
|
673
|
|
|
674 The 'columns' and 'lines' options are used to set or get the width and height
|
|
|
675 of the display.
|
|
|
676
|
|
|
677 Option settings are read from the first and last few lines of the file.
|
|
|
678 Option 'modelines' determines how many lines are tried (default is 5). Note
|
|
|
679 that this is different from the Vi versions that can execute any Ex command
|
|
|
680 in a modeline (a major security problem). |trojan-horse|
|
|
|
681
|
|
|
682 If the 'insertmode' option is set (e.g. in .exrc), Vim starts in insert mode.
|
|
|
683 And it comes back there, when pressing <Esc>.
|
|
|
684
|
|
|
685 Undo information is kept in memory. Available memory limits the number and
|
|
|
686 size of change that can be undone. This may be a problem with MS-DOS, is
|
|
|
687 hardly a problem on the Amiga and almost never with Unix and Win32.
|
|
|
688
|
|
|
689 If the 'backup' or 'writebackup' option is set: Before a file is overwritten,
|
|
|
690 a backup file (.bak) is made. If the "backup" option is set it is left
|
|
|
691 behind.
|
|
|
692
|
|
|
693 Vim creates a file ending in ".swp" to store parts of the file that have been
|
|
|
694 changed or that do not fit in memory. This file can be used to recover from
|
|
|
695 an aborted editing session with "vim -r file". Using the swap file can be
|
|
|
696 switched off by setting the 'updatecount' option to 0 or starting Vim with
|
|
|
697 the "-n" option. Use the 'directory' option for placing the .swp file
|
|
|
698 somewhere else.
|
|
|
699
|
|
|
700 Vim is able to work correctly on filesystems with 8.3 file names, also when
|
|
|
701 using messydos or crossdos filesystems on the Amiga, or any 8.3 mounted
|
|
|
702 filesystem under Unix. See |'shortname'|.
|
|
|
703
|
|
|
704 Error messages are shown at least one second (Vi overwrites error messages).
|
|
|
705
|
|
|
706 If Vim gives the |hit-enter| prompt, you can hit any key. Characters other
|
|
|
707 than <CR>, <NL> and <Space> are interpreted as the (start of) a command. (Vi
|
|
|
708 only accepts a command starting with ':').
|
|
|
709
|
|
|
710 The contents of the numbered and unnamed registers is remembered when
|
|
|
711 changing files.
|
|
|
712
|
|
|
713 The "No lines in buffer" message is a normal message instead of an error
|
|
|
714 message, since that may cause a mapping to be aborted.
|
|
|
715
|
|
|
716 The AUX: device of the Amiga is supported.

719 6. Command-line arguments *cmdline-arguments*
|
|

895 7. POSIX compliance *posix* *posix-compliance*
|
|
160
|
896
|
|
|
897 In 2005 the POSIX test suite was run to check the compatiblity of Vim. Most
|
|
164
|
898 of the test was executed properly. There are the few things where Vim
|
|
166
|
899 is not POSIX compliant, even when run in Vi compatibility mode.
|
|
160
|
900
|
|
164
|
901 Set the $VIM_POSIX environment variable to have 'cpoptions' include the POSIX
|
|
|
902 flags when Vim starts up. This makes Vim run as POSIX as it can. That's
|
|
166
|
903 a bit different from being Vi compatible.
|
|
164
|
904
|
|
|
905 This is where Vim does not behave as POSIX specifies and why:
|
|
|
906
|
|
160
|
907 *posix-screen-size*
|
|
164
|
908 The $COLUMNS and $LINES environment variables are ignored by Vim if
|
|
|
909 the size can be obtained from the terminal in a more reliable way.
|
|
|
910 Add the '|' flag to 'cpoptions' to have $COLUMNS and $LINES overrule
|
|
|
911 sizes obtained in another way.
|
|
160
|
912
|
|
164
|
913 The "{" and "}" commands don't stop at a "{" in the original Vi, but
|
|
|
914 POSIX specifies it does. Add the '{' flag to 'cpoptions' if you want
|
|
|
915 it the POSIX way.
|
|
|
916
|
|
|
917 The "D", "o" and "O" commands accept a count. Also when repeated.
|
|
|
918 Add the '#' flag to 'cpoptions' if you want to ignore the count.
|
|
160
|
919
|
|
166
|
920 The ":cd" command fails if the current buffer is modified when the '.'
|
|
|
921 flag is present in 'cpoptions'.
|
|
|
922
|
|
|
923 There is no ATTENTION message, the "A" flag is added to 'shortmess'.
|
|
|
924
|
|
|
925 These are remarks about running the POSIX test suite:
|
|
|
926 - vi test 33 sometimes fails for unknown reasons
|
|
|
927 - vi test 250 fails; behavior will be changed in a new revision
|
|
|
928 http://www.opengroup.org/austin/mailarchives/ag-review/msg01710.html
|
|
|
929 - vi test 310 fails; exit code non-zero when any error occurred?
|
|
|
930 - ex test 24 fails because test is wrong. Changed between SUSv2 and SUSv3.
|
|
|
931 - ex tests 47, 48, 49, 72, 73 fail because .exrc file isn't read in silent
|
|
|
932 mode and $EXINIT isn't used.
|
|
|
933 - ex tests 76, 78 fail because echo is used instead of printf. (fixed)
|
|
|
934 Also: problem with \s not changed to space.
|
|
|
935 - ex test 355 fails because 'window' isn't used for "30z".
|
|
|
936 - ex test 368 fails because shell command isn't echoed in silent mode.
|
|
|
937 - ex test 394 fails because "=" command output isn't visible in silent mode.
|
|
|
938 - ex test 411 fails because test file is wrong, contains stray ':'.
|
|
|
939 - ex test 475 and 476 fail because reprint output isn't visible in silent mode.
|
|
|
940 - ex test 480 and 481 fail because the tags file has spaces instead of a tab.
|
|
|
941 - ex test 502 fails because .exrc isn't read in silent mode.
|
|
|
942 - ex test 509 fails because .exrc isn't read in silent mode. and exit code is
|
|
|
943 1 instead of 2.
|
|
|
944 - ex test 534 fails because .exrc isn't read in silent mode.
