How do I search the open buffers in Vim?

Question

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 li

Answer 1

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()

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 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 .

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.
