For project that uses feature branches and merge requests, it is common that the CHANGELOG.md will have conflicts. In order to prevent that, it is better to manage changelog items in a separate folder (./changelog) and generate the CHANGELOG.md during release.

This gem defines a bunch of commands to simplify the management of changelog items in ./changelog.

The CHANGELOG.md generated will follow the amazing keepachangelog format.

Add this line to your application's Gemfile:

gem 'changelog-rb'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install changelog-rb

- changelog
  - 0.1.1
    - fixed_something.yml
    - tag.yml
  - 0.1.0
    - added_something.yml
    - changed_something.yml
    - tag.yml
  - unreleased
    - added_something.yml
    - changed_something.yml
    - removed_something.yml

All the pending/unreleased changelog items should be in the unreleased folder. Once you release a new version, the corresponding changelog items in unreleased should be moved over to [RELEASE VERSION] folder.

The tag.yml in release folder is for recording the date of release.

There are a bunch of commands helping you to manage the changelog items. They are base on the awesome library thor so you can always check all the command options by running changelog help [COMMAND].

Set up the basic folder structure.

$ changelog setup

Add a changelog item.

| -t | Type of changes (one of the following Added, Changed, Deprecated, Removed, Fixed, Security) | If not specified, it will try to derive it from the first word of the title | | -u | Author | If not specified, it will be $USER | | -g | From git commit comment | Magic. Get the git commit comment as changelog title. Please try to use it with gitmoji. |

$ changelog add "Changed something"
# type: Changed
# title: Changed something
# user: someone

$ changelog add "Support something" -t Changed
# type: Changed
# title: Support something
# user: someone

$ git commit -m "Fixed something"
$ changelog add -g
# type: Fixed
# title: Fixed something
# user: someone

$ gitmoji
$ changelog add -g
# type: Added
# title: ✨Added something
# user: someone

Move unreleased changelog items to the version given and tag today as release date.

$ changelog tag 0.1.0

Move the changelog items in version back to unreleased and clean it up.

$ changelog untag 0.1.0

Convert ./changelog to CHANGELOG.md

$ changelog print

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
