This is an adaptation of Ack.vim to use Ag instead. Ag can be used as a replacement for 99% of the uses of grep. This plugin will allow you to run ag from vim, and shows the results in a split window. This plugin is almost copy and pasted from mileszs' ack.vim plugin.
You have to install ag, of course.
Install with Homebrew:
brew install the_silver_searcher
Otherwise, you are on your own.
If you have Rake installed, you can just run: rake install.
Otherwise, the file ag.vim goes in ~/.vim/plugin, and the ag.txt file belongs in ~/.vim/doc. Be sure to run
:helptags ~/.vim/doc
afterwards.
:Ag [options] {pattern} [{directory}]
Search recursively in {directory} (which defaults to the current directory) for the {pattern}.
Files containing the search term will be listed in the split window, along with the line number of the occurrence, once for each occurrence. [Enter] on a line in this window will open the file, and place the cursor on the matching line.
Just like where you use :grep, :grepadd, :lgrep, and :lgrepadd, you can use :Ag, :AgAdd, :LAg, and :LAgAdd respectively. (See doc/ag.txt, or install and :h Ag for more information.)
In the quickfix window, you can use:
o to open (same as enter)
go to preview file (open but maintain focus on ag.vim results)
t to open in new tab
T to open in new tab silently
v to open in vertical split
gv to open in vertical split silently
q to close the quickfix window
