Question

I would like findstr /m background *.vim | gvim to open all *.vim files containing background in a single instance of gvim – but I can’t get the piping to work.

This is very similar to this question but instead of capturing the stdin output I would like GViM to treat the output as a list of files to be opened – and on a Windows system so xargs isn’t guaranteed. Any ideas?

Answer 1

I can think of a few ways of doing this:

Use vimgrep

Use vimgrep: after running gvim, enter:

:vimgrep /background/ **/*.vim

This will populate the quickfix list with all of the matches (possibly more than one per file), so you can use things like :copen, :cw, :cn etc to navigate (see :help quickfix)

Use vim’s built-in cleverness

Use findstr to give you a list of files and then get vim to open those files:

findstr /m background *.vim > list_of_files.txt
gvim list_of_files.txt

" In Gvim, read each file into the buffer list:
:g/^/exe 'badd' getline('.')

" Open the files in tabs:
:bufdo tabedit %

This will load each file, but will keep the list of files open as well (you can always bunload it or whatever).

Edit:

Using :tabedit on a list of files didn’t work (I’d only tested :badd). You can get round this by either using badd and then bufdo (as above) or by doing something like this (put it in your vimrc):

command! -range=% OpenListedFiles <line1>,<line2>call OpenListedFiles()

function! OpenListedFiles() range
    let FileList = getline(a:firstline, a:lastline)
    for filename in FileList
        if filereadable(filename)
            exe 'tabedit' filename
        endif
    endfor
endfunction

Then simply open the file containing all of your required file names and type:

:OpenListedFiles

Use Vim’s server functionality and some awful batch scripting

Use the server functionality and some batch script magic (which I don’t understand as I use bash)

@echo off
REM Welcome to the hideous world of Windows batch scripts
findstr /m background *.vim > list_of_files.txt
REM Run GVIM (may not be required)
gvim
REM Still in command prompt or .bat file here
REM for each line in the file "list_of_files.txt", pass the line to OpenInTab
for /f %%i in (list_of_files.txt) do call:OpenInTab %%i
goto:eof

:OpenInTab
REM Open the file in a separate tab of an existing vim instance
gvim --remote-tab %~1
goto:eof

Eeeurrgh.

If it were me, I would go with the “Use vim’s built-in cleverness” option. Actually, that’s not true: I’d use cygwin’s bash script and just use bash, but if I HAD to do it with the native tools, I’d use the built-in cleverness approach.
