vim: jump to buffer that contains /string/ - vim

I normally have quite a few buffers opened, which I navigate using combination of Bufexplorer and FuzzyFinder. Finding the right buffer still involves going through file names. But often, it could be much easier to say something like 'jump to buffer that contains "wip"'. Anyone knows how?

I am using a small function I put inside my .vimrc:
function! s:GrepOpenBuffers(search, jump)
call setqflist([])
let cur = getpos('.')
silent! exe 'bufdo vimgrepadd /' . a:search . '/ %'
let matches = len(getqflist())
if a:jump && matches > 0
sil! cfirst
else
call setpos('.', cur)
endif
echo 'BufGrep:' ((matches) ? matches : 'No') 'matches found'
endfunction
com! -nargs=1 -bang BufGrep call <SID>GrepOpenBuffers('<args>', <bang>0)
You could use something like the above to grep for a search term in all opened buffers.

Vim language: send current word to CtrlP

I know how to use CtrlP. I type ctrl+p, then I start to write file name, ... and so on. But, ... I am very lazy developer. I want to directly send to CtrlP current word. I know how to get current word:
let l:currentWord = expand('<cword>')
In Vim Language, ... I How can I send l:currentWord to CtrlP?
map <F6> :call ComposerKnowWhereCurrentFileIs()<CR>
function! ComposerKnowWhereCurrentFileIs()
let l:currentWord = expand('<cword>')
let l:command = "grep " . l:currentWord . " ../path/to/composer -R | awk '{print $6}' | awk -F\\' '{print $2}'"
let l:commandFileFound = l:command . ' | wc -l'
let l:numberOfResults = system(l:commandFileFound)
if l:numberOfResults == 1
let l:fileName = system(l:command)
let l:openFileCommand = 'tabe /path/to/project' . l:fileName
exec l:openFileCommand
else
echo "Too many files :-( - use CtrlP ;-) "
endif
endfunction
<C-P><C-\>w
See :h ctrlp-mappings. You may map this combination:
map <F6> <C-P><C-\>w
In a function:
exe "normal \<C-P>" . expand('<cword>')
The whole point of CtrlP and similar plugins is to provide an alternative command-line where you can refine your search as you type.
If you don't need fuzzy search and you already have the filename under the cursor… why not simply use the built-in gf?
-- edit --
In the gif below:
I jump to /path/not/knowable/BlaBlaClassName.php with gf,
I jump back to the previous buffer with <C-^> (unrelated to your question),
I jump to the declaration of BlaBlaClassName in /path/not/knowable/BlaBlaClassName.php again with <C-]> thanks to a tagsfile generated with ctags.
function! LazyP()
let g:ctrlp_default_input = expand('<cword>')
CtrlP
let g:ctrlp_default_input = ''
endfunction
command! LazyP call LazyP()
nnoremap <C-P> :LazyP<CR>
(this could probably be simplified but I suck at vim syntax)
For that, you wouldn't use the <C-P> mapping, but the :CtrlP command, as that one takes parameters.
To build a mapping that passes the current word to the command, there are two approaches. Either directly insert the current word into the command-line (via :help c_CTRL-R_CTRL-W):
:nnoremap <Leader>p :CtrlP <C-r><C-p><CR>
Or, in order to use expand(), build the Ex command via :execute:
:nnoremap <Leader>p :execute 'CtrlP' expand('<cword>')<CR>

Yanking all marked lines in vim

Often times when reviewing log files in vim, I'll highlight interesting lines using marks. At some point, I'd like to be able to copy all of the interesting lines (either all marked lines, or a list of marks) to either a register or another file (it doesn't really matter which; the goal is to facilitate writing a summary). I haven't been able to find any built in way to do this; is it possible in vim?
I suppose it's probably a fairly straightforward function; probably looking something like this, but my vimscript abilities are very weak:
for cur_mark in list_of_marks
goto mark
yank current line and append to register
Has anyone ever written anything similar that they can point me to?
Thanks
EDIT: I posted the accepted solution at https://github.com/mikeage/vim-yankmarks
As always, there are few things that are more motivating than asking for help. Here's what I came up with; feedback welcome.
function! Yankmark()
let save_cursor = getpos(".")
let n = 0
" I should really make this a parameter...
let marks_to_yank="abcdefghijklmnopqrstuvwxyz"
let nummarks = strlen(marks_to_yank)
" Clear the a register
let #a=''
while n < nummarks
let c = strpart(marks_to_yank, n, 1)
" Is the mark defined
if getpos("'".c)[2] != 0
" using g' instead of ' doesn't mess with the jumplist
exec "normal g'".c
normal "Ayy
endif
let n = n + 1
endwhile
call setpos('.', save_cursor)
endfunction
Mikeage had a great idea; here's a more refined version of his function turned into a command:
":YankMarks [{marks}] [{register}]
" Yank all marked (with [a-z] / {marks} marks) lines into
" the default register / {register} (in the order of the
" marks).
function! s:YankMarks( ... )
let l:marks = 'abcdefghijklmnopqrstuvwxyz'
let l:register = '"'
if a:0 > 2
echohl ErrorMsg
echomsg 'Too many arguments'
echohl None
return
elseif a:0 == 2
let l:marks = a:1
let l:register = a:2
elseif a:0 == 1
if len(a:1) == 1
let l:register = a:1
else
let l:marks = a:1
endif
endif
let l:lines = ''
let l:yankedMarks = ''
for l:mark in split(l:marks, '\zs')
let l:lnum = line("'" . l:mark)
if l:lnum > 0
let l:yankedMarks .= l:mark
let l:lines .= getline(l:lnum) . "\n"
endif
endfor
call setreg(l:register, l:lines, 'V')
echomsg printf('Yanked %d line%s from mark%s %s',
\ len(l:yankedMarks),
\ len(l:yankedMarks) == 1 ? '' : 's',
\ len(l:yankedMarks) == 1 ? '' : 's',
\ l:yankedMarks
\) . (l:register ==# '"' ? '' : ' into register ' . l:register)
endfunction
command! -bar -nargs=* YankMarks call <SID>YankMarks(<f-args>)
A different way of accomplishing this might be using the :global command. The global command takes the form :g/{pattern}/{cmd}. The command, {cmd}, will be executed on all lines matching {pattern}.
Append lines matching a pattern to a register:
:g/pattern/yank A
Append matching line to a log file:
:g/pattern/w >> file.log
Of course if you want to find line matching a mark you can match it in your pattern. The following pattern matches a line with mark m.
:g/\%'m/w >> file.log
To do something like this. (Note: I am using \v to turn on very magic)
:g/\v(%'a|%'b|%'m)/yank A
Of course if a pattern won't work you can do this by hand. Instead of marking the lines just build up the lines as you go. Just yank a line to an uppercase register to append.
"Ayy
Or do a write append with a range of a single line
:.w >> file.log
For more help see
:h :g
:h :w_a
:h /\%'m
:h /\v
You can do something like:
:redir #a
:silent marks XYZN
:redir END
"ap
That way the output of the :marks command will be redirected to the a register. Note, that it will only lists (in the above case) the X, Y, Z and N marks (as the arguments), and if there was an a register, it will be deleted/overwritten.
Also note, that it might not give the desired output, but gives you a starting point...
I like the solution from Mikeage, though I would probably solve this with the multiselect - Create multiple selections and operate plugin. This also has the benefit that you don't run out of marks.
With the plugin, you can select lines with <Leader>msa or :MSAdd. Finally, yank all lines with:
:let #a=''
:MSExecCmd yank A
If you use an upper-case register name when yanking into a specific register, Vim will append the yanked content instead of overwriting the register's value.
So, for example:
"ayy - yank current line to register a, overwriting
[move]
"Ayy - append this line to register a
[move]
"ap - paste all yanked material
See :help quotea for more details.

Vim E139: Workaround

I have a MoveToFile Function that appends selected text to a file and then deletes it.
command! -nargs=* -complete=file -range=% -bang -bar MoveToFile
\ :<line1>,<line2>call MoveToFile(<q-args>, <bang>0)
function! MoveToFile(fname, overwrite) range
let r = a:firstline . ',' . a:lastline
exe r 'w>>' . ' !'[a:overwrite] . fnameescape(a:fname)
exe r 'd'
endfunction
A problem arises when the file I'm trying to append to is already open in Vim. How can I get around this?
You can catch the E139: File is loaded in another buffer. If you really need
to handle this corner case, yank the contents, open the existing buffer via :buffer {fname}, and paste them:
try
exe r 'w>>' . ' !'[a:overwrite] . fnameescape(a:fname)
catch /^Vim\%((\a\+)\)\=:E139/
exe r 'yank'
exe 'sbuffer' fnameescape(a:fname)
$put
hide
endtry
You can use writefile() (note that this will overwrite file hence must first get current contents hence is unusable for large ones):
function MoveToFile(fname, _) range abort
let lines=readfile(a:fname, 'b')
if !empty(lines) && empty(lines[-1])
call remove(lines, -1)
endif
let [first, last]=((a:firstline>a:lastline)?([a:lastline, a:firstline]):([a:firstline, a:lastline]))
let lines+=getline(first, last)+['']
call writefile(lines, a:fname, 'b')
execute first.','.last.'delete _'
endfunction
Note: to get the same encoding as with :w>> you need to replace line
let lines+=getline(first, last)+['']
with
let lines+=map(getline(first, last), 'iconv(v:val, &enc, &fenc)')+['']
. To also respect 'dos' file format:
let lines+=map(getline(first, last), 'iconv(v:val, &enc, &fenc)'.((&ff is# 'dos')?('."\r"'):('')))+[(&ff is# 'dos')?("\r"):('')]
(respecting 'mac' file format is trickier).

Favourite places in vim

Is there a command in vim that can bookmark a place (path to the file, line number in that file), so that I can go to that place easily later?
It would be similar as NERDTree :Bookmark command. You can open your file with NERDTreeFromBookmark. I'm looking for the same functionality with the difference that bookmark is not only a file but file + line number.
Thank you
Yes you can do so with the 'mark' command. There are two types of bookmarks you can create, local and global. You are referring to a global bookmark.
You can type 'mP' to create a bookmark called P. Notice the case, uppercase indicates it is a global bookmark. To go to that bookmark, type `P.
Hope this helps
Source
The viminfo setting can contain the option !, which makes it store any global variables with uppercase letters in the viminfo file. Using this, you can define a variable called g:BOOKMARKS and store your bookmarks in there.
Here's some vimscript you could use to do that:
set viminfo+=!
if !exists('g:BOOKMARKS')
let g:BOOKMARKS = {}
endif
" Add the current [filename, cursor position] in g:BOOKMARKS under the given
" name
command! -nargs=1 Bookmark call s:Bookmark(<f-args>)
function! s:Bookmark(name)
let file = expand('%:p')
let cursor = getpos('.')
if file != ''
let g:BOOKMARKS[a:name] = [file, cursor]
else
echom "No file"
endif
wviminfo
endfunction
" Delete the user-chosen bookmark
command! -nargs=1 -complete=custom,s:BookmarkNames DelBookmark call s:DelBookmark(<f-args>)
function! s:DelBookmark(name)
if !has_key(g:BOOKMARKS, a:name)
return
endif
call remove(g:BOOKMARKS, a:name)
wviminfo
endfunction
" Go to the user-chosen bookmark
command! -nargs=1 -complete=custom,s:BookmarkNames GotoBookmark call s:GotoBookmark(<f-args>)
function! s:GotoBookmark(name)
if !has_key(g:BOOKMARKS, a:name)
return
endif
let [filename, cursor] = g:BOOKMARKS[a:name]
exe 'edit '.filename
call setpos('.', cursor)
endfunction
" Completion function for choosing bookmarks
function! s:BookmarkNames(A, L, P)
return join(sort(keys(g:BOOKMARKS)), "\n")
endfunction
I'm not sure how readable the code is, but basically, the Bookmark command accepts a single parameter to use as a name. It will store the current filename and cursor position to the g:BOOKMARKS dictionary. You can use the GotoBookmark command with a mark name to go to it. DelBookmark works in the same way, but deletes the given mark. Both functions are tab-completed.
Another way to jump through them is by using this command:
" Open all bookmarks in the quickfix window
command! CopenBookmarks call s:CopenBookmarks()
function! s:CopenBookmarks()
let choices = []
for [name, place] in items(g:BOOKMARKS)
let [filename, cursor] = place
call add(choices, {
\ 'text': name,
\ 'filename': filename,
\ 'lnum': cursor[1],
\ 'col': cursor[2]
\ })
endfor
call setqflist(choices)
copen
endfunction
CopenBookmarks will load the bookmarks in the quickfix window, which seems like a nice interface to me.
This solution is similar to Eric's -- it uses the .viminfo file, so if something goes wrong with it, you'll probably lose your marks. And if you save your marks in one vim instance, they won't be immediately available in another.
I don't know how comfortable your are with vimscript, so just in case -- to use this, you can put the code in a file under your plugin vimfiles directory, for example plugin/bookmarks.vim. Should be completely enough. Here's the entire code in a gist as well: https://gist.github.com/1371174
EDIT: Changed the interface for the solution a bit. Original version can be found in the gist history.
I have used this script (number marks). There might be better ones though. Wait for other answers!
This doesn't solve your problem as stated, but you may find it helps.
MRU.vim - Most Recently Used files plugin
Type :MRU and you get a nice searchable list of your most recently used files. Pressing enter on one brings you to it.

" And open enough folds to make the cursor is not folded
" Don't do it when the position is invalid or when inside an event handler

How to delete multiple buffers in Vim?

Assuming I have multiple files opened as buffers in Vim. The files have *.cpp, *.h and some are *.xml. I want to close all the XML files with :bd *.xml. However, Vim does not allow this (E93: More than one match...).
Is there any way to do this?
P.S. I know that :bd file1 file2 file3 works. So can I somehow evaluate *.xml to file1.xml file2.xml file3.xml?
You can use <C-a> to complete all matches. So if you type :bd *.xml and then hit <C-a>, vim will complete the command to :bd file1.xml file2.xml file3.xml.
:3,5bd[elete]
Will delete buffer range from 3 to 5 .
You also can use alternatively use:
:.,$-bd[elete] " to delete buffers from the current one to last but one
:%bd[elete] " to delete all buffers
You can use this.
:exe 'bd '. join(filter(map(copy(range(1, bufnr('$'))), 'bufname(v:val)'), 'v:val =~ "\.xml$"'), ' ')
It should be quite easy to add it to a command.
function! s:BDExt(ext)
let buffers = filter(range(1, bufnr('$')), 'buflisted(v:val) && bufname(v:val) =~ "\.'.a:ext.'$"')
if empty(buffers) |throw "no *.".a:ext." buffer" | endif
exe 'bd '.join(buffers, ' ')
endfunction
command! -nargs=1 BDExt :call s:BDExt(<f-args>)
Try the script below. The example is for "txt", change it as needed, e.g. to "xml".
Modified buffers are not deleted. Press \bd to delete the buffers.
map <Leader>bd :bufdo call <SID>DeleteBufferByExtension("txt")
function! <SID>DeleteBufferByExtension(strExt)
if (matchstr(bufname("%"), ".".a:strExt."$") == ".".a:strExt )
if (! &modified)
bd
endif
endif
endfunction
[Edit]
Same without :bufdo (as requested by Luc Hermitte, see comment below)
map <Leader>bd :call <SID>DeleteBufferByExtension("txt")
function! <SID>DeleteBufferByExtension(strExt)
let s:bufNr = bufnr("$")
while s:bufNr > 0
if buflisted(s:bufNr)
if (matchstr(bufname(s:bufNr), ".".a:strExt."$") == ".".a:strExt )
if getbufvar(s:bufNr, '&modified') == 0
execute "bd ".s:bufNr
endif
endif
endif
let s:bufNr = s:bufNr-1
endwhile
endfunction
I too had a need for this functionality all the time. This is the solution I have in my vimrc.
function! GetBufferList()
return filter(range(1,bufnr('$')), 'buflisted(v:val)')
endfunction
function! GetMatchingBuffers(pattern)
return filter(GetBufferList(), 'bufname(v:val) =~ a:pattern')
endfunction
function! WipeMatchingBuffers(pattern)
let l:matchList = GetMatchingBuffers(a:pattern)
let l:count = len(l:matchList)
if l:count < 1
echo 'No buffers found matching pattern ' . a:pattern
return
endif
if l:count == 1
let l:suffix = ''
else
let l:suffix = 's'
endif
exec 'bw ' . join(l:matchList, ' ')
echo 'Wiped ' . l:count . ' buffer' . l:suffix . '.'
endfunction
command! -nargs=1 BW call WipeMatchingBuffers('<args>')
Now, I can just do :BW regex (e.g. :BW \.cpp$ and wipe all matching buffers that have match that pattern in their pathname.
If you want to delete rather than wipe, you can of course replace exec 'bw ' . join(l:matchList, ' ') with exec 'bd ' . join(l:matchList, ' ')
TAB will only autocomplete one file for you as of Vim 7.4.282
use <c-a> to autocomplete all files.
You can just use:
bd filetype
then just use <c-a> to facilitate the completion of all open files of specified filetype.
for example, you have 1.xml, 2.xml, 3.xml, and 4.xml,
you can do:
bd xml
then press <c-a>
vim will autocomplete for you as follow:
bd 1.xml 2.xml 3.xml 4.xml
you can just press enter to complete the command.
if you have made changes in one of the files mentioned above, do remember to do:
bd! xml
Very simply: use the :bd[elete] command. For example, :bd[elete] buf#1 buf#5 buf#3 will delete the buffers 1, 3, and 5.
