For a pretty colorful output of Reek, which is an awesome gem! This is just something I came up with while learning Thor.
To make your refactoring life easier you can also use Guard::Preek!

$ gem install preek

From source

$ git clone git@github.com:joenas/preek.git
$ cd preek
$ rake install

Usage:
  preek FILE(S)|DIR
Options:
  -i, [--irresponsible]  # Include IrresponsibleModule smell in output.
  -c, [--compact]        # Compact output.
  -v, [--verbose]        # Report files with no smells
Commands:
  preek git                # Run Preek on git changes
  preek help [COMMAND]     # Describe available commands or one specific command
  preek smell FILE(S)|DIR  # Pretty format Reek output
  preek version            # Shows version

At the moment it only supports files, not stuff like this:

$ echo "def x() true end" | reek

# Convenience method, prints all smells in files
filenames = Dir['**/*.rb']
Preek::Smell(filenames)
# To exclude certain smell classes
excludes = %w(IrresponsibleModule)
Preek::Smell(filenames, excludes)

To run preek on your code before commit, place this in .git/hooks/pre-commit

#!/bin/sh
exec bundle exec preek git
