*tips.txt* For Vim version 7.0aa. Last change: 2005 Apr 19 VIM REFERENCE MANUAL by Bram Moolenaar Tips and ideas for using Vim *tips* Don't forget to browse the user manual, it also contains lots of useful tips |usr_toc.txt|. Editing C programs |C-editing| Finding where identifiers are used |ident-search| Switching screens in an xterm |xterm-screens| Scrolling in Insert mode |scroll-insert| Smooth scrolling |scroll-smooth| Correcting common typing mistakes |type-mistakes| Counting words, lines, etc. |count-items| Restoring the cursor position |restore-position| Renaming files |rename-files| Speeding up external commands |speed-up| Useful mappings |useful-mappings| Compressing the help files |gzip-helpfile| Hex editing |hex-editing| Executing shell commands in a window |shell-window| Using <> notation in autocommands |autocmd-<>| ============================================================================== Editing C programs *C-editing* There are quite a few features in Vim to help you edit C program files. Here is an overview with tags to jump to: |usr_29.txt| Moving through programs chapter in the user manual. |usr_30.txt| Editing programs chapter in the user manual. |C-indenting| Automatically set the indent of a line while typing text. |=| Re-indent a few lines. |format-comments| Format comments. |:checkpath| Show all recursively included files. |[i| Search for identifier under cursor in current and included files. |[_CTRL-I| Jump to match for "[i" |[I| List all lines in current and included files where identifier under the cursor matches. |[d| Search for define under cursor in current and included files. |CTRL-]| Jump to tag under cursor (e.g., definition of a function). |CTRL-T| Jump back to before a CTRL-] command. |:tselect| Select one tag out of a list of matching tags. |gd| Go to Declaration of local variable under cursor. |gD| Go to Declaration of global variable under cursor. |gf| Go to file name under the cursor. |%| Go to matching (), {}, [], /* */, #if, #else, #endif. |[/| Go to previous start of comment. |]/| Go to next end of comment. |[#| Go back to unclosed #if, #ifdef, or #else. |]#| Go forward to unclosed #else or #endif. |[(| Go back to unclosed '(' |])| Go forward to unclosed ')' |[{| Go back to unclosed '{' |]}| Go forward to unclosed '}' |v_ab| Select "a block" from "[(" to "])", including braces |v_ib| Select "inner block" from "[(" to "])" |v_aB| Select "a block" from "[{" to "]}", including brackets |v_iB| Select "inner block" from "[{" to "]}" ============================================================================== Finding where identifiers are used *ident-search* You probably already know that |tags| can be used to jump to the place where a function or variable is defined. But sometimes you wish you could jump to all the places where a function or variable is being used. This is possible in two ways: 1. Using the |:grep| command. This should work on most Unix systems, but can be slow (it reads all files) and only searches in one directory. 2. Using ID utils. This is fast and works in multiple directories. It uses a database to store locations. You will need some additional programs for this to work. And you need to keep the database up to date. Using the GNU id-tools: What you need: - The GNU id-tools installed (mkid is needed to create ID and lid is needed to use the macros). - An identifier database file called "ID" in the current directory. You can create it with the shell command "mkid file1 file2 ..". Put this in your .vimrc: > map _u :call ID_search()<Bar>execute "/\\<" . g:word . "\\>"<CR> map _n :n<Bar>execute "/\\<" . g:word . "\\>"<CR> function! ID_search() let g:word = expand("<cword>") let x = system("lid --key=none ". g:word) let x = substitute(x, "\n", " ", "g") execute "next " . x endfun To use it, place the cursor on a word, type "_u" and vim will load the file that contains the word. Search for the next occurrence of the word in the same file with "n". Go to the next file with "_n". This has been tested with id-utils-3.2 (which is the name of the id-tools archive file on your closest gnu-ftp-mirror). [the idea for this comes from Andreas Kutschera] ============================================================================== Switching screens in an xterm *xterm-screens* *xterm-save-screen* (From comp.editors, by Juergen Weigert, in reply to a question) :> Another question is that after exiting vim, the screen is left as it :> was, i.e. the contents of the file I was viewing (editing) was left on :> the screen. The output from my previous like "ls" were lost, :> ie. no longer in the scrolling buffer. I know that there is a way to :> restore the screen after exiting vim or other vi like editors, :> I just don't know how. Helps are appreciated. Thanks. : :I imagine someone else can answer this. I assume though that vim and vi do :the same thing as each other for a given xterm setup. They not necessarily do the same thing, as this may be a termcap vs. terminfo problem. You should be aware that there are two databases for describing attributes of a particular type of terminal: termcap and terminfo. This can cause differences when the entries differ AND when of the programs in question one uses terminfo and the other uses termcap (also see |+terminfo|). In your particular problem, you are looking for the control sequences ^[[?47h and ^[[?47l. These switch between xterms alternate and main screen buffer. As a quick workaround a command sequence like > echo -n "^[[?47h"; vim ... ; echo -n "^[[?47l" may do what you want. (My notation ^[ means the ESC character, further down you'll see that the databases use \E instead). On startup, vim echoes the value of the termcap variable ti (terminfo: smcup) to the terminal. When exiting, it echoes te (terminfo: rmcup). Thus these two variables are the correct place where the above mentioned control sequences should go. Compare your xterm termcap entry (found in /etc/termcap) with your xterm terminfo entry (retrieved with /usr/5bin/infocmp -C xterm). Both should contain entries similar to: > :te=\E[2J\E[?47l\E8:ti=\E7\E[?47h: PS: If you find any difference, someone (your sysadmin?) should better check the complete termcap and terminfo database for consistency. NOTE 1: If you recompile Vim with FEAT_XTERM_SAVE defined in feature.h, the builtin xterm will include the mentioned "te" and "ti" entries. NOTE 2: If you want to disable the screen switching, and you don't want to change your termcap, you can add these lines to your .vimrc: > :set t_ti= t_te= ============================================================================== Scrolling in Insert mode *scroll-insert* If you are in insert mode and you want to see something that is just off the screen, you can use CTRL-X CTRL-E and CTRL-X CTRL-Y to scroll the screen. |i_CTRL-X_CTRL-E| To make this easier, you could use these mappings: > :inoremap <C-E> <C-X><C-E> :inoremap <C-Y> <C-X><C-Y> (Type this literally, make sure the '<' flag is not in 'cpoptions'). You then lose the ability to copy text from the line above/below the cursor |i_CTRL-E|. Also consider setting 'scrolloff' to a larger value, so that you can always see some context around the cursor. If 'scrolloff' is bigger than half the window height, the cursor will always be in the middle and the text is scrolled when the cursor is moved up/down. ============================================================================== Smooth scrolling *scroll-smooth* If you like the scrolling to go a bit smoother, you can use these mappings: > :map <C-U> <C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y><C-Y> :map <C-D> <C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E><C-E> (Type this literally, make sure the '<' flag is not in 'cpoptions'). ============================================================================== Correcting common typing mistakes *type-mistakes* When there are a few words that you keep on typing in the wrong way, make abbreviations that correct them. For example: > :ab teh the :ab fro for ============================================================================== Counting words, lines, etc. *count-items* To count how often any pattern occurs in the current buffer use the substitute command and add the 'n' flag to avoid the substitution. The reported number of substitutions is the number of items. Examples: > :%s/./&/gn characters :%s/\i\+/&/gn words :%s/^//n lines :%s/the/&/gn "the" anywhere :%s/\<the\>/&/gn "the" as a word You might want to reset 'hlsearch' or do ":nohlsearch". Add the 'e' flag if you don't want an error when there are no matches. An alternative is using |v_g_CTRL-G| in Visual mode. If you want to find matches in multiple files use |:vimgrep|. *count-bytes* If you want to count bytes, you can use this: Visually select the characters (block is also possible) Use "y" to yank the characters Use the strlen() function: > :echo strlen(@") A line break is counted for one byte. ============================================================================== Restoring the cursor position *restore-position* Sometimes you want to write a mapping that makes a change somewhere in the file and restores the cursor position, without scrolling the text. For example, to change the date mark in a file: > :map <F2> msHmtgg/Last [cC]hange:\s*/e+1<CR>"_D"=strftime("%Y %b %d")<CR>p'tzt`s Breaking up saving the position: ms store cursor position in the 's' mark H go to the first line in the window mt store this position in the 't' mark Breaking up restoring the position: 't go to the line previously at the top of the window zt scroll to move this line to the top of the window `s jump to the original position of the cursor ============================================================================== Renaming files *rename-files* Say I have a directory with the following files in them (directory picked at random :-): buffer.c charset.c digraph.c ... and I want to rename *.c *.bla. I'd do it like this: > $ vim :r !ls *.c :%s/$.*$.c/mv & \1.bla :w !sh :q! ============================================================================== Speeding up external commands *speed-up* In some situations, execution of an external command can be very slow. This can also slow down wildcard expansion on Unix. Here are a few suggestions to increase the speed. If your .cshrc (or other file, depending on the shell used) is very long, you should separate it into a section for interactive use and a section for non-interactive use (often called secondary shells). When you execute a command from Vim like ":!ls", you do not need the interactive things (for example, setting the prompt). Put the stuff that is not needed after these lines: > if ($?prompt == 0) then exit 0 endif Another way is to include the "-f" flag in the 'shell' option, e.g.: > :set shell=csh\ -f (the backslash is needed to include the space in the option). This will make csh completely skip the use of the .cshrc file. This may cause some things to stop working though. ============================================================================== Useful mappings *useful-mappings* Here are a few mappings that some people like to use. *map-backtick* > :map ' ` Make the single quote work like a backtick. Puts the cursor on the column of a mark, instead of going to the first non-blank character in the line. *emacs-keys* For Emacs-style editing on the command-line: > " start of line :cnoremap <C-A> <Home> " back one character :cnoremap <C-B> <Left> " delete character under cursor :cnoremap <C-D> <Del> " end of line :cnoremap <C-E> <End> " forward one character :cnoremap <C-F> <Right> " recall newer command-line :cnoremap <C-N> <Down> " recall previous (older) command-line :cnoremap <C-P> <Up> " back one word :cnoremap <Esc><C-B> <S-Left> " forward one word :cnoremap <Esc><C-F> <S-Right> NOTE: This requires that the '<' flag is excluded from 'cpoptions'. |<>| *format-bullet-list* This mapping will format any bullet list. It requires that there is an empty line above and below each list entry. The expression commands are used to be able to give comments to the parts of the mapping. > :let m = ":map _f :set ai<CR>" " need 'autoindent' set :let m = m . "{O<Esc>" " add empty line above item :let m = m . "}{)^W" " move to text after bullet :let m = m . "i <CR> <Esc>" " add space for indent :let m = m . "gq}" " format text after the bullet :let m = m . "{dd" " remove the empty line :let m = m . "5lDJ" " put text after bullet :execute m |" define the mapping (<> notation |<>|. Note that this is all typed literally. ^W is "^" "W", not CTRL-W. You can copy/paste this into Vim if '<' is not included in 'cpoptions'.) Note that the last comment starts with |", because the ":execute" command doesn't accept a comment directly. You also need to set 'textwidth' to a non-zero value, e.g., > :set tw=70 A mapping that does about the same, but takes the indent for the list from the first line (Note: this mapping is a single long line with a lot of spaces): > :map _f :set ai<CR>}{a <Esc>WWmmkD`mi<CR><Esc>kkddpJgq}'mJO<Esc>j < *collapse* These two mappings reduce a sequence of empty (;b) or blank (;n) lines into a single line > :map ;b GoZ<Esc>:g/^$/.,/./-j<CR>Gdd :map ;n GoZ<Esc>:g/^[ <Tab>]*$/.,/[^ <Tab>]/-j<CR>Gdd ============================================================================== Compressing the help files *gzip-helpfile* For those of you who are really short on disk space, you can compress the help files and still be able to view them with Vim. This makes accessing the help files a bit slower and requires the "gzip" program. (1) Compress all the help files: "gzip doc/*.txt". (2) Edit "doc/tags" and change the ".txt" to ".txt.gz": > :%s=$\t.*\.txt$\t=\1.gz\t= (3) Add this line to your vimrc: > set helpfile={dirname}/help.txt.gz Where {dirname} is the directory where the help files are. The |gzip| plugin will take care of decompressing the files. You must make sure that $VIMRUNTIME is set to where the other Vim files are, when they are not in the same location as the compressed "doc" directory. See |$VIMRUNTIME|. ============================================================================== Executing shell commands in a window *shell-window* There have been questions for the possibility to execute a shell in a window inside Vim. The answer: you can't! Including this would add a lot of code to Vim, which is a good reason not to do this. After all, Vim is an editor, it is not supposed to do non-editing tasks. However, to get something like this, you might try splitting your terminal screen or display window with the "splitvt" program. You can probably find it on some ftp server. The person that knows more about this is Sam Lantinga <slouken@cs.ucdavis.edu>. An alternative is the "window" command, found on BSD Unix systems, which supports multiple overlapped windows. Or the "screen" program, found at www.uni-erlangen.de, which supports a stack of windows. ============================================================================== Hex editing *hex-editing* *using-xxd* See section |23.4| of the user manual. If one has a particular extension that one uses for binary files (such as exe, bin, etc), you may find it helpful to automate the process with the following bit of autocmds for your <.vimrc>. Change that "*.bin" to whatever comma-separated list of extension(s) you find yourself wanting to edit: > " vim -b : edit binary using xxd-format! augroup Binary au! au BufReadPre *.bin let &bin=1 au BufReadPost *.bin if &bin | %!xxd au BufReadPost *.bin set ft=xxd | endif au BufWritePre *.bin if &bin | %!xxd -r au BufWritePre *.bin endif au BufWritePost *.bin if &bin | %!xxd au BufWritePost *.bin set nomod | endif augroup END ============================================================================== Using <> notation in autocommands *autocmd-<>* The <> notation is not recognized in the argument of an :autocmd. To avoid having to use special characters, you could use a self-destroying mapping to get the <> notation and then call the mapping from the autocmd. Example: *map-self-destroy* > " This is for automatically adding the name of the file to the menu list. " It uses a self-destroying mapping! " 1. use a line in the buffer to convert the 'dots' in the file name to \. " 2. store that in register '"' " 3. add that name to the Buffers menu list " WARNING: this does have some side effects, like overwriting the " current register contents and removing any mapping for the "i" command. " autocmd BufNewFile,BufReadPre * nmap i :nunmap i<CR>O<C-R>%<Esc>:.g/\./s/\./\\./g<CR>0"9y$u:menu Buffers.<C-R>9 :buffer <C-R>%<C-V><CR><CR> autocmd BufNewFile,BufReadPre * normal i Another method, perhaps better, is to use the ":execute" command. In the string you can use the <> notation by preceding it with a backslash. Don't forget to double the number of existing backslashes and put a backslash before '"'. > autocmd BufNewFile,BufReadPre * exe "normal O\<C-R>%\<Esc>:.g/\\./s/\\./\\\\./g\<CR>0\"9y$u:menu Buffers.\<C-R>9 :buffer \<C-R>%\<C-V>\<CR>\<CR>" For a real buffer menu, user functions should be used (see |:function|), but then the <> notation isn't used, which defeats using it as an example here. vim:tw=78:ts=8:ft=help:norl:
