How to integrate grep or rg with vim?

[Masber]

Dear fzf community,

I am learning how to configure vim and trying to customize my vim-fzf experience...
I would like to know how to integrate grep/rg with fzf in vim.

I tried the following which does not work:

nnoremap <Leader>sg :call fzf#run({'source': 'rg', 'sink': 'e', 'down': '40%'})<CR>

Any advice?

thank you very much

rg by itself needs a search pattern so that source command exits without producing search results

if you have both fzf and fzf.vim installed you can use the built in :Rg command instead

for your mapping use

nnoremap <Leader>sg :Rg<CR>

or run :Rg your_pattern directly

fzf.vim handles the filename and line number from each result so selecting one opens the matching location
using e as the sink would treat the whole search result as a filename

the setup and command are covered in the fzf.vim readme
