Question:how to use Rg on current word/selection

[nkh]

• [x ] I have fzf 0.30.0 or above
• [x ] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
• [ x] I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
• [x ] I have read through the manual page of fzf (man fzf)
• [ x] I have searched through the existing issues

fzf.vim Rg is slowly replacing ctags for me, I'd like to Rg the current word or selection, can't find an example here nor in will wild internet.

nnoremap <leader>a :Rg <c-r><c-w><cr> for word under cursor.

@lanker Great! thank you.

This is a bit old but I'll leave a different option below, it might be helpful to others.

Another strategy is to forward the current word as the search query, when it is empty.

For example in the context of the Advanced ripgrep integration the below would fallback on the current word if nothing is provided (similar to how vim-ripgrep behaves) :

fun! s:RGSearchTerm(query)
  if empty(a:query)
    return expand("<cword>")
  else
    return a:query
  endif
endfun

function! RipgrepFzf(query, fullscreen)
  let query = s:RGSearchTerm(a:query)
  let command_fmt = 'rg --column --line-number --no-heading --color=always --smart-case %s || true'
  let initial_command = printf(command_fmt, shellescape(query))
  let reload_command = printf(command_fmt, '{q}')
  let spec = {'options': ['--disabled', '--query', query, '--bind', 'change:reload:'.reload_command]}
  let spec = fzf#vim#with_preview(spec, 'right', 'ctrl-/')
  call fzf#vim#grep(initial_command, 1, fzf#vim#with_preview(spec), a:fullscreen)
endfunction

command! -nargs=* -bang RG call RipgrepFzf(<q-args>, <bang>0)

@okoriko "Another strategy is to forward the current word as the search query, when it is empty." doesn't make any sense to me; could you please explain?

The code above searches for the current word and not positioned on a word you get to give the search.
