Rake::Gitversion

This gem adds a task 'set_version' to rake, which uses annotated tags and the 'git describe' command to get a version string and save it to a VERSION file. The patch number of the version string is the number of commits since the last version tag. If the git tree is dirty, minor is increased and the version marked as prerelease by adding '.dev'.

Add this line to your application's Gemfile:

gem 'rake-gitversion'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rake-gitversion

In your Rakefile:

require 'rake/gitversion'

Add an annotated version tag:

git tag -a -m 'minor' v0.1

Run rake set_version.

Consider adding VERSION to your .gitignore file, but make sure to run to rake set_version after checkout or distribute VERSION file somehow.

In your version.rb, use:

# Version of gem and module
VERSION = begin
  File.read('VERSION')
rescue
  '0.pre'
end.freeze

After checking out the repo, run bundle install to install dependencies. Then, run rake test to run the tests.

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.
