We often search our projects for specific text within Vim like so:
However, we have a need for speed. How can we grep faster?
Override to use The Silver Searcher
" The Silver Searcher if executable('ag') " Use ag over grep set grepprg=ag\ --nogroup\ --nocolor " Use ag in CtrlP for listing files. Lightning fast and respects .gitignore let g:ctrlp_user_command = 'ag %s -l --nocolor -g ""' " ag is fast enough that CtrlP doesn't need to cache let g:ctrlp_use_caching = 0 endif
Search for the word under the cursor
This searches for the text under the cursor and shows the results in a “quickfix” window:
" bind K to grep word under cursor nnoremap K :grep! "\b<C-R><C-W>\b"<CR>:cw<CR>
It looks like this when we hit
K with our cursor over
in the Upcase repo:
Cursor over each search result, hit
Enter, and the file will be opened.
This defines a new command
Ag to search for the provided text and open a
" bind \ (backward slash) to grep shortcut command -nargs=+ -complete=file -bar Ag silent! grep! <args>|cwindow|redraw!
We can map it to any character, such as
nnoremap \ :Ag<SPACE>
\ is pressed, Vim waits for our input:
ag arguments may be passed in at this point:
:Ag -i Stripe app/models
Enter results in:
