KeepTheChange

This gem provides an easy-to-use interface for parsing CHANGELOG files that strictly adhere to keep a changelog format.

The idea is loosely based on vandamme gem, but is supposed to evolve into something more strict (in terms of supported formats), but also more feature-rich.

Add this line to your application's Gemfile:

gem 'keepthechange'

And then execute:

$ bundle

Or install it yourself as:

$ gem install keepthechange

parser = KeepTheChange::Parser.new(changelog: File.read('CHANGELOG.md'))
changes_hash = parser.parse

This will produce a hash where keys are version numbers (e.g. 0.1.0, 1.0.3) and values are hashes themselves. Those will have headers as keys (e.g. Added, Fixed) and changesets as corresponding values.

If you only provide one argument to combine_changes(), the resulting output will contain changes since that version.

File.write('SINCE_0.1.7.md', parser.combine_changes('0.1.7'))

0.1.7 itself won't be included in the resulting file.

Specify both the lower and upper bound (again - lower bound is exclusive) to produce output with changes between the versions.

File.write('0.1.7-1.0.3.md', parser.combine_changes('0.1.7', '1.0.3'))

After checking out the repo, run bundle install to install dependencies. Then, run bundle exec rake spec to run the tests. You can also run bin/simple_test after putting a TEST_CHANGELOG.md into the repo directory for a basic parsing test.

To install this gem onto your local machine, run bundle exec rake install.
