pre-commit hook - check trailing white-spaces, unicode chars, jshint, rubocop
#!/bin/sh
#
# An example hook script to verify what is about to be committed.
# Called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.

# To enable this hook, rename this file to "pre-commit".

Add a custom method definition to Test Blueprints in Machinist::Mongoid. It is very handy in the tests to have extra helper methods directly on the Test Blueprints without defining those in the corresponding Model class.

INSTALLATION

echo "gem 'machinist_blueprint_with_method',\
      git: 'git://gist.github.com/6204150.git',\
      group: 'test'" >> Gemfile
