Make :Ag not match file names, only the file content

Since there is a command :Files that can search files by name, I'd like to configure :Ag to only look at the file contents, not at the file names.

I'll demostrate my case below, my question is: can this be achieved today, maybe with some configuration?

---

To see why this is an annoying issue, create a file called demo.txt, put 20 lines each having a random number, and on the 21st line write demo. Then use :Ag demo to search for this string.

Expected: you find only one occurrence.
Actual: you also find 20 irrelevant occurrences.

Try this:

command! -bang -nargs=* Ag call fzf#vim#ag(<q-args>, {'options': '--delimiter : --nth 4..'}, <bang>0)

It looks like magic, but works beautifully, thanks @junegunn! 🎉

I'm trying to figure out how to run that command on startup. Any tips?

[backdoer]

Put it in your .vimrc @mbylstra

🤦‍♂️ I thought I had to prepend it with autocmd which wasn't working. Thanks!

Is it possible to combine this with my current Ag tweaks?
I have the following:

command! -bang -nargs=* Ag
  \ call fzf#vim#ag(<q-args>,
  \                 {'options': '--delimiter : --nth 4..'}, " Can't add this
  \                 <bang>0 ? fzf#vim#with_preview('up:60%')
  \                         : fzf#vim#with_preview('right:50%:hidden', '?'),
  \                 <bang>0)

@junegunn could you please help, is it possible to combine preview options with search only by files with Ag?

[junegunn]

* fzf#vim#with_preview([[options], preview window, [toggle keys...]])

So you have to write

fzf#vim#with_preview({'options': '--delimiter : --nth 4..'}, 'up:60%')

@junegunn Thank you so much, you've saved my day!

@junegunn i used the method you described above but im experiencing some strange behavior.

i want to have 2 options:

1. use the default :Ag behavior of searching all file names and content.
2. use Ag to only search the current file contents.

Im noticing that with my current config, this only works some in some projects, but not others. and on occasion, it will only allow me to use option 2 once in a project, and every time afterwards it goes back to the default behavior. do you have any idea why this is?

here is my config:

nnoremap <Leader>sa :Ag<CR>
nnoremap <Leader>ss :Ag!<CR>

command! -bang -nargs=* Ag
  \ call fzf#vim#ag(<q-args>,
  \                 <bang>0 ? fzf#vim#with_preview({'options': '--delimiter : --nth 4..'}, 'up:60%')
  \                         : fzf#vim#with_preview('right:50%:hidden', '?'),
  \                 <bang>0)

Try this:

command! -bang -nargs=* Ag call fzf#vim#ag(<q-args>, {'options': '--delimiter : --nth 4..'}, <bang>0)

Thanks for this! Can anyone care to explain (briefly) what this exactly does?

Basically, the {'options'...} part is passed into fzf. If you look at the man page for fzf, you'll notice you can pass a delimiter when searching, in this case our delimiter is colon :. Then we tell it to only search from the 4th item onwards... these are the file contents only.

If you look at the results of :Ag, it uses : as the separator for each result.

Can anyone help me write the equivalent for Ripgrep? This:

command! -bang -nargs=* Rg call fzf#vim#rg(<q-args>, {'options': '--delimiter : --nth 4..'}, <bang>0)

Gives me the error
E117: Unkown function: fzf#vim#rg

[fabiomcosta]

@danamkaplan fzf#vim#rg function doesn't exists, as the error message says, so you have to use the fzf#vim#grep function.

I got it working with the following command:

command! -bang -nargs=* Rg
  \ call fzf#vim#grep("rg --column --line-number --no-heading --color=always --smart-case ".shellescape(<q-args>), 1, {'options': '--delimiter : --nth 4..'}, <bang>0)

Got that from

fzf.vim/plugin/fzf.vim

Line 52 in 359a80e

\'command! -bang -nargs=* Rg call fzf#vim#grep("rg --column --line-number --no-heading --color=always --smart-case ".shellescape(<q-args>), 1, <bang>0)',

and then added the same argument that has been provided to Ag.

Oh just noticed this has also been suggested at #714 (comment)

[avral]

Thank's!

[buschco]

Try this:

command! -bang -nargs=* Ag call fzf#vim#ag(<q-args>, {'options': '--delimiter : --nth 4..'}, <bang>0)

This made my Preview window disappear. How can I bring it back with this options?

EDIT
I think I figured it out:

command! -bang -nargs=* Ag call fzf#vim#ag(<q-args>, fzf#vim#with_preview({'options': '--delimiter : --nth 4..'}), <bang>0)
