Speed up your Rails development with one-git-checkout-and-bash-script-install
It adds sprinter (bash script) to your bin path and detects if there is spring-loaded rake available in your current folder whenever you run rake. Continue using your normal workflow but get the massive speed gain from running the spring-loaded version from Rails.
Checkout and install the script by running:
cd /tmp; git clone git@github.com:MrTin/sprinter.git && cd sprinter; ./install.sh'
Follow the on-screen instructions to finish the process.
Just clone the repo, push a new branch and open up a PR.
This has only been tested on OS X 10.9 and OS X 10.10 but I don't see why this should not work on any major *nix distribution too.
