Development Tips

Local gem modifications

If you want to modify the gems setup for development needs, create a file Gemfile.local.rb in the root of your hammer-cli checkout. You can override the setup from Gemfile there. This file is git-ignored so you can easily keep your custom tuning.

Typical usage is for linking plugins from local checkouts:

gem 'hammer_cli_foreman', :path => '../hammer-cli-foreman'

Debugging with Pry

Pry is a runtime developer console for ruby. It allows debugging when Pry Debugger is installed alongside.

For basic usage, add following the lines to your Gemfile.local.rb:

gem 'pry'
gem 'pry-debugger', :platforms => [:ruby_19]

Then add this line at the place where you want the script to break:

require 'pry'; binding.pry

Pry Debugger supports all expected debugging features. See its documentation for details.
