OldeCodeFinder

OldeCodeFinder finds old code. This means files which are largely older than a specific date.

It can also find files which were mostly written by a particular person. So if Fred left the company 3 years ago, files which consist mostly of lines which were written by him may be worth revisiting.

Installation

Add this line to your application's Gemfile in the 'development' group:

gem 'olde_code_finder'

Usage

See if more than 80% of app/models/foo.rb was written by Benjamin Franklin:

bundle exec rake olde_code_finder:find_by_author['app/models/foo.rb','Benjamin Franklin','80']

Or you can use a glob:

bundle exec rake olde_code_finder:find_by_author['app/models/*.rb','Benjamin Franklin','80']

Or you can specify a lower percentage threshold:

bundle exec rake olde_code_finder:find_by_author['app/models/*.rb','Benjamin Franklin','60']

The author name is a regex, so this will find 'Benjamin Franklin' as well as 'Ben Franklin':

bundle exec rake olde_code_finder:find_by_author['app/models/*.rb','Frank','80']

Or you can run a different task and find code older than a certain date instead:

bundle exec rake olde_code_finder:find_by_date['app/models/*.rb','4 years','80']

The output will be a list of files that meet the criteria:

foo> $ bundle exec rake olde_code_finder:find_by_author['app/models/*.rb','Benjamin Franklin','80']
More than 80% of app/models/foobar.rb was written by Benjamin Franklin (85%)

How does it work?

It uses git blame to see who last touched each line of a file and when.
