Convenient commands for ripgrep and fzf.vim integration

.zshrc

# RIPGREP config (this is the environment variable that vim is reading when building the rg command)
# In this case the shell is zsh. Adjust accordingly based on preferred shell and needs.
export RG_COMMAND_BASE='rg --ignore-file ~/.ignore --hidden --follow'

# Minimal FZF config. Shares the RG_COMMAND_BASE env var.
[ -f $HOME/.fzf.zsh ] && source $HOME/.fzf.zsh
export FZF_DEFAULT_COMMAND="$RG_COMMAND_BASE --files"

rg_fzf.vim

" set up an rg command with options for reuse. Refer to the other gist file (.zshrc) for details on $RG_COMMAND_BASE
let g:rg_command = $RG_COMMAND_BASE . ' --column --line-number --no-heading --color "always"'

" concatenate together all the necessary options for the final call to the rg command
fun! BuildRgCommand(opts, qargs)
  let l:list = [g:rg_command] + a:opts + ['--', shellescape(a:qargs)]
  return join(l:list, ' ')
endfun

" construct the rg command and pass it to the fzf grep command with all necessary options
fun! Fzf_grep(opts, qargs, bang) abort
  let l:rg = BuildRgCommand(a:opts, a:qargs)
  call fzf#vim#grep(l:rg, 1, {}, a:bang)
endfun

" custom commands

" Search literal string recursive ignoring case
command! -bang -nargs=* RG call Fzf_grep(['--ignore-case', '--fixed-strings'], <q-args>, <bang>0)

Hi GB, I'm well thanks. Based on the error that you have there it *seems* like the fzf.vim plugin, particularly the fzf#run function is having trouble with indexing an array. I honestly can't say I know what's happening there. I don't normally run GVIM. What I would do in this case is try to use the stock functionality that comes with fzf.vim without any of the custom commands I made and see if you still experience any issues with it, just to rule out any incompatibilities between fzf.vim and GVIM. If everything works fine, then we know that the custom commands are an issue somehow. Aaron

The above gist you had shared is working fine without any issue in VIM. However, if I try "RG <pattern" in GVIM, I am getting errors. What I am observing is GVIM doesn't seem to be able to get the files based on the pattern given. It is showing all the files in a separate window. I verified that the rg command is working correctly if I run manually. rg command being used: rg --ignore-file ~/.ignore --hidden --follow --column --line-number --no-heading --color "always" --ignore-case --fixed-strings -- 'master' FZF_DEFAULT_COMMAND is: rg --ignore-file ~/.ignore --hidden --follow --files If I select one of those files, I get the below error: Error detected while processing function Fzf_grep[3]..fzf#vim#grep[25]..42_ fzf[18]..fzf#run[63]..15_callback: line 21: Vim(let):E684: list index out of range: 1 Here are the details of versions: $ vim --version VIM - Vi IMproved 8.0 (2016 Sep 12, compiled May 20 2017 00:44:30) Included patches: 1-600 Compiled by ***@***.*** $ gvim --version VIM - Vi IMproved 8.0 (2016 Sep 12, compiled May 20 2017 00:44:30) Included patches: 1-600 Compiled by ***@***.*** Thanks gb — You are receiving this because you authored the thread.

Thanks Aaron. No problem.

Will check if I can figure it out. It is not urgent now.

Good day
