Currently I have this mapping in my ~/.vimrc
noremap <Leader>a :Ack <cword><cr>
which enables me to search for a word under the cursor.
I would like to search for a current visual selection instead, because sometimes words are not enough.
Is there a way I can send visual selection to ack.vim
?
You can write a visual-mode map that yanks the highlighted text and then pastes it verbatim (properly escaped) onto the vim command-line:
vnoremap <Leader>a y:Ack <C-r>=fnameescape(@")<CR><CR>
This solution uses the <C-r>=
trick that allows you to enter a kind of second-level command-line, which allows you to enter any vimscript expression, which is then evaluated, and the result is stringified and pasted onto the (original, first-level) command-line where the cursor is.
A slight disadvantage of this approach is that it commandeers the unnamed register, which you may not want.
