I usually customize existing colorscheme to meet my needs.
If I could get the syntax group name under cursor, it would help me a lot, just like Firebug but in Vim. I'd like to know how to do it.
There is this function that was floating around the web when I was doing the same thing:
function! SynStack()
if !exists("*synstack")
return
endif
echo map(synstack(line('.'), col('.')), 'synIDattr(v:val, "name")')
endfunc
The following function will output both the name of the syntax group, and the translated syntax group of the character the cursor is on:
function! SynGroup()
let l:s = synID(line('.'), col('.'), 1)
echo synIDattr(l:s, 'name') . ' -> ' . synIDattr(synIDtrans(l:s), 'name')
endfun
To make this more convenient it can be wrapped in a custom command or key binding.
How this works:
line('.') and col('.') return the current position
synID(...) returns a numeric syntax ID
synIDtrans(l:s) translates the numeric syntax id l:s by following highlight links
synIDattr(l:s, 'name') returns the name corresponding to the numeric syntax ID
This will echo something like:
vimMapModKey -> Special
Here's a mapping that will show the hierarchy of the synstack() and also show the highlight links. press gm to use it.
function! SynStack ()
for i1 in synstack(line("."), col("."))
let i2 = synIDtrans(i1)
let n1 = synIDattr(i1, "name")
let n2 = synIDattr(i2, "name")
echo n1 "->" n2
endfor
endfunction
map gm :call SynStack()<CR>
Try this:
" diagnostics {{{
if has('balloon_eval')
nnoremap <F12> : setl beval!<CR>
set bexpr=InspectSynHL()
endif
fun! InspectSynHL()
let l:synNames = []
let l:idx = 0
for id in synstack(v:beval_lnum, v:beval_col)
call add(l:synNames, printf('%s%s', repeat(' ', idx), synIDattr(id, 'name')))
let l:idx+=1
endfor
return join(l:synNames, "\n")
endfun
"}}}

Using vim or nvim, when I open a new vim terminal digraphs display correctly. See below:
However, whenever I change colorscheme (any, it is not specific to a particular colorscheme) - then the digraphs appear highlighted. The highlighting remains even when switching back to the original colorscheme. This happens with any digraph, not just the one shown in this question.
See below:
Cannot find a way to remove that highlighting, or prevent it happening in the first place. Have tried commands like :highlight nonascii none but had no luck. Any help / suggestions much appreciated.
Most/Some of the colorschemes aren't really made for hotswap.
It seems to be a rather common problem with solarized f.e.
There is a plugin which handles a change cleanly: https://github.com/xolox/vim-colorscheme-switcher (I haven't tested it).
And I copied a bunch of functions for that somewhere which works arround the problems most of the time. I don't know where I got it from, but I want to be clear, it is not my work!

Let's say I'm restructuring some text including a line that contains the text "log". After a bit more editing, I want to paste the log line, but its now in some far-off register. Is there a way to search all registers for the first that contains the term "log" and paste its contents?
The following should do the job:
function! SearchAndPasteReg()
let l:pattern = input('Reg search: ')
if l:pattern == '' | return | endif
for l:i in range(1, 9)
if match(eval('#'.l:i), l:pattern) != -1
execute printf('normal "%i]p', l:i)
return
endif
endfor
redraw | echo 'Pattern not found'
endf
nnoremap <silent> ]R :call SearchAndPasteReg()<cr>
I'm not sure if you are talking about numbered registers, or all the registers. If you want to search for all regs, just extend the range with a list containing all the desired register names, something like this:
function! SearchAndPasteReg()
let l:pattern = input('Reg search: ')
if l:pattern == '' | return | endif
let l:regs = range(char2nr('1'), char2nr('9'))
call map(extend(l:regs, range(char2nr('a'), char2nr('z'))), 'nr2char(v:val)')
for l:reg in l:regs
if match(eval('#'.l:reg), l:pattern) != -1
execute printf('normal "%s]p', l:reg)
return
endif
endfor
redraw | echo 'Pattern not found'
endf
nnoremap <silent> ]R :call SearchAndPasteReg()<cr>
One way(not very handy though) would be to redirect output to a register you don't use, lets say z.
:redir #z
list registries
:reg
And paste the result from "z in some buffer and then is searchable.
And you will also have to stop the redirection after.
:redir END
With a third party plugin maybe, but you can still use the :reg[isters] command to see the content of all your registers or :reg 0123456789 for only the numbered registers.
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.
I'd like to search for text in all files currently open in vim and display all results in a single place. There are two problems, I guess:
I can't pass the list of open files to :grep/:vim, especially the names of files that aren't on the disk;
The result of :grep -C 1 text doesn't look good in the quickfix window.
Here is a nice example of multiple file search in Sublime Text 2:
Any ideas?
Or
:bufdo vimgrepadd threading % | copen
The quickfix window may not look good for you but it's a hell of a lot more functional than ST2's "results panel" if only because you can keep it open and visible while jumping to locations and interact with it if it's not there.
ack and Ack.vim handle this problem beautifully. You can also use :help :vimgrep. For example:
:bufdo AckAdd -n threading
will create a nice quickfix window that lets you hop to the cursor position.
Like the answer of Waz, I have written custom commands for that, published in my GrepCommands plugin. It allows to search over buffers (:BufGrep), visible windows (:WinGrep), tabs, and arguments.
(But like all the other answers, it doesn't handle unnamed buffers yet.)
I really liked romainl's answer, but there were a few sticky edges that made it awkward to use in practice.
The following in your .vimrc file introduces a user command Gall (Grep all) that addresses the issues that I found irksome.
funct! GallFunction(re)
cexpr []
execute 'silent! noautocmd bufdo vimgrepadd /' . a:re . '/j %'
cw
endfunct
command! -nargs=1 Gall call GallFunction(<q-args>)
This will allow case-sensitive searches like this:
:Gall Error\C
and case-insensitive:
:Gall error
and with spaces:
:Gall fn run
Pros
It will only open the Quickfix window, nothing else.
It will clear the Quickfix window first before vimgrepadd-ing results from each buffer.
The Quickfix window will contain the locations of all matches throughout the open buffers, not just the last visited.
Use :Gall repeatedly without any special housekeeping between calls.
Doesn't wait on errors and displays results immediately.
Doesn't allow any autocmd to run, speeding up the overall operation.
Ambivalent features
Doesn't preemptively jump to any occurrence in the list. :cn gets second result or CTRL-w b <enter> to get to the first result directly.
Cons
If there's only one result, you'll have to navigate to it manually with CTRL-w b <enter>.
To navigate to a result in any buffer quickly:
:[count]cn
or
:[count]cp
E.g. :6cn to skip 6 results down the list, and navigate to the correct buffer and line in the "main" window.
Obviously, window navigation is essential:
Ctrl-w w "next window (you'll need this at a bare minimum)
Ctrl-w t Ctrl-w o "go to the top window then close everything else
Ctrl-w c "close the current window, i.e. usually the Quickfix window
:ccl "close Quickfix window
If you close the Quickfix window, then need the results again, just use:
:cw
or
:copen
to get it back.
I made this function a long time ago, and I'm guessing it's probably not the cleanest of solutions, but it has been useful for me:
" Looks for a pattern in the open buffers.
" If list == 'c' then put results in the quickfix list.
" If list == 'l' then put results in the location list.
function! GrepBuffers(pattern, list)
let str = ''
if (a:list == 'l')
let str = 'l'
endif
let str = str . 'vimgrep /' . a:pattern . '/'
for i in range(1, bufnr('$'))
let str = str . ' ' . fnameescape(bufname(i))
endfor
execute str
execute a:list . 'w'
endfunction
" :GrepBuffers('pattern') puts results into the quickfix list
command! -nargs=1 GrepBuffers call GrepBuffers(<args>, 'c')
" :GrepBuffersL('pattern') puts results into the location list
command! -nargs=1 GrepBuffersL call GrepBuffers(<args>, 'l')
An improved (on steroids) version of Waz's answer, with better buffer searching and special case handling, can be found below (The moderators wouldn't let me update Waz's answer anymore :D).
A more fleshed out version with binds for arrow keys to navigate the QuickFix list and F3 to close the QuickFix window can be found here: https://pastebin.com/5AfbY8sm

Suppose that I have a document like this, and I want to search for all occurences of the URL:
Vim resources: [http://example.com/search?q=vim][q]
...
[q]: http://example.com/search?q=vim
I don't want to type it out in full, so I'll place my cursor on the first URL, and run "uyi[ to yank it into the 'u' register. Now to search for it, I'd like to just paste the contents of that register into the search field by running:
/\V<c-r>u<CR>
This results in Vim searching for the string 'http:' - because the '/' character terminates the search field.
I can get around the problem by running this instead:
/\V<c-r>=escape(#u, '\/')<CR><CR>
But it's a lot of typing!
How can I create a mapping for Vim's commandline that simplifies this workflow?
My ideal workflow would go something like this:
press /\V to bring up the search prompt, and use very nomagic mode
hit ctrl-x to trigger the custom mapping (ctrl-x is available)
Vim listens for the next key press... (pressing <Esc> would cancel)
pressing 'u' would escape the contents of the 'u' register, and insert on the command line
Try this:
cnoremap <c-x> <c-r>=<SID>PasteEscaped()<cr>
function! s:PasteEscaped()
" show some kind of feedback
echo ":".getcmdline()."..."
" get a character from the user
let char = getchar()
if char == "\<esc>"
return ''
else
let register_content = getreg(nr2char(char))
return escape(register_content, '\/')
endif
endfunction
By the way, something that might be useful to know (if you don't already) is that you can use ? as the delimiter for :s. Which means that you could write a search-and-replace for an url like so:
:s?http://foo.com?http://bar.com?g
I've accepted Andrew Radev's solution, which solved the hard parts. But here's the version that I've added to my vimrc file, which adds a couple of enhancements:
cnoremap <c-x> <c-r>=<SID>PasteEscaped()<cr>
function! s:PasteEscaped()
echo "\\".getcmdline()."\""
let char = getchar()
if char == "\<esc>"
return ''
else
let register_content = getreg(nr2char(char))
let escaped_register = escape(register_content, '\'.getcmdtype())
return substitute(escaped_register, '\n', '\\n', 'g')
endif
endfunction
This should work:
whether you use / or ? (to search forwards, or backwards)
and when the pasted register includes multiple lines
Also, I changed the prompt. While waiting for a register, the prompt switches to \ - which seems like a suitable cue for 'PasteEscaped'. Also, I've appended a ", which mimics Vim's behavior after pressing <c-r> at the command line.
If you've any further suggestions for improvements, please leave a comment.
How about different workflow? For example, creating your own operator to search target text as is:
" https://gist.github.com/1213642
" Requiement: https://github.com/kana/vim-operator-user
map YourFavoriteKeySequence <Plug>(operator-search-target-text)
call operator#user#define('search-target-text', 'OperatorSerachTargetText')
function! OperatorSerachTargetText(motion_wise)
execute 'normal!' '`['.operator#user#visual_command_from_wise_name(a:motion_wise).'`]"xy'
let #/ = '\V' . escape(substitute(#x, '[\r\n]$', '', ''), '\')
normal! n
endfunction
I like #nelstrom's solution and made a small change to support escaping [ and ].
cnoremap <c-x> <c-r>=<SID>PasteEscaped()<cr>
function! s:PasteEscaped()
echo "\\".getcmdline()."\""
let char = getchar()
if char == "\<esc>"
return ''
else
let register_content = getreg(nr2char(char))
let escaped_register = escape(register_content, '\'.getcmdtype())
let escaped_register2 = substitute(escaped_register,'[','\\[','g')
let escaped_register3 = substitute(escaped_register2,']','\\]','g')
return substitute(escaped_register3, '\n', '\\n', 'g')
endif
endfunction
