I could search through my Rails app directory with no problem but if I was in the full root then searching through the development log and plugins would result in the machine freezing up for up to 2 minutes while grep worked its way through the filesystem. Thankfully, Find in Files now uses Ack which speeds things up tremendously.
Ack is perfect for this plugin. Looking at the benchmarks, you can see it's over 4x faster than grep for searching through documents and subdirectories. This will be clearly noticeable to anyone who uses this new version of the plugin. It is much faster.
The issue is that we can't assume people have Ack installed so the plugin gracefully degrades to grep if it can't detect Ack properly. One warning, on Debian and Ubuntu systems, the package is not installed by default. Actually, the ack package in Karmic Koala is a Kanji translator.. so in order to get the right version to use with this plugin, get the ack-grep package instead.
sudo apt-get install ack-grep
If you need to run this plugin on another platform you may need to change the command or create a symlink between ack-grep and your local ack command. Sorry about that.. Linux is a bit too diverse for me to cleanly figure out how to access ack across all distributions. But for Debian and Ubuntu you should be good to go out of the box assuming you have ack-grep installed.
Get the updated plugin from GitHub. Happy hacking everyone!
