Isolate for Rails Apps
Published 2010-02-04 @ 14:17
I work on a lot of stuff. I’d rather have my laptop’s gem installs be for my stuff, not my work stuff. I’d especially rather not deal with the version mess you get into when you’ve got several different rails apps. Isolate makes this incredibly easy. With just one gem system-installed, you can make every project completely standalone:
A New Rails App:
% rails blah
You can use isolate with just two files in your rails app. You just add the following:
require "rubygems" require "isolate" Isolate.gems "vendor/isolated" do gem "rails", "= 2.0.2" environment :development do gem "vlad" gem "sqlite3-ruby" end environment :test do gem "minitest" end end
% rake -t (in /Users/ryan/blah2) [1/3] Isolating rails (= 2.0.2). [2/3] Isolating vlad (>= 0). [3/3] Isolating sqlite3-ruby (>= 0). Building native extensions. This could take a while...
That’s it! It has really made my work a lot easier! I don’t have to
deal with umpteen different dependencies that I’ll never use on
another project. I never need to have unknown artifacts breaking
stuff. Everything is very cleanly documented within the
block. I love isolate. You should check it out if you haven’t already.
