I’m a big fan of splitting up applications into separate pieces whenever possible. This is especially convenient in Ruby with tools like bundler & rubygems to make modularization a breeze.
Often when I turn something into a gem, I want to work on my application and its dependency at the same time. For that reason, bundler let’s you declare dependencies by path, instead of rebuilding:
If a normally line in your Gemfile looks like:
you can specify a path as an argument to `gem` like:
gem 'autodoc', :path => '/Users/john/Development/autodoc'
