Thor::SCMVersion

Thor tasks to manage a VERSION file based on SCM tags, for use in continuous delivery pipelines.

One of the key points of continuous delivery is that every build has a version number, and that version number is unique and only points to one build. Thor::SCMVersion adds some tasks to a Thorfile to use SCM tags as the authoritative source of version status, so your continuous integration server can create versions without having to worry about file conflicts.

Integrating into your project

Since Thor is written in Ruby, you'll need Ruby to make this work, on your workstation and on your CI server. See http://whatisthor.com/ for more in how to use Thor.

Get the gem

If you don't already have a Gemfile, you should probably get one. See http://gembundler.com/ for more details on Bundler and Gemfiles. Not required, but will save you a lot of hassle.

Add this line to your application's Gemfile:

gem 'thor-scmversion'

And then execute:

$ bundle

Or install it yourself as:

$ gem install thor-scmversion

Add it to your Thorfile

All you need to do is require it at the top of your Thorfile:

require 'thor/scmversion'

Now when you list your thor tasks you'll see 2 new ones.

$ thor list

version
-------
thor version:bump TYPE [PRERELEASE_TYPE]  # Bump version number (type is major, minor, patch, prerelease or auto)
                                          # Prerelease allows an additional parameter to be passed which is used 
                                          # as the prerelease type.
thor version:current    # Show current SCM tagged version

Usage Examples:

$ thor version:current
1.2.1
$ thor version:bump auto
1.2.2
$ thor version:bump major
2.0.0
$ thor version:bump prerelease
2.0.1-alpha.1
$ thor version:bump prerelease
2.0.1-alpha.2
$ thor version:bump prerelease beta
2.0.1-beta.1
$ thor version:bump minor
2.1.0

Remove your VERSION file from source control

Since your CI server will be managing your VERSION file, you don't want it to be stored in your SCM anymore. Make a note of your current version, then

$ git rm VERSION
$ echo VERSION >> .gitignore`
$ git add .gitignore
$ git commit -m "Drop VERSION as it is managed by thor-scmversion now"

Create a tag for the current version

Now tag the current version manually. If it was 1.2.3:

$ git tag 1.2.3
$ git push --tags

You can make sure it worked by running thor version:current and making sure it is what you expected.

Integrate with CI

Now, as part of your CI job, before it builds your artifacts, have it run thor version:bump patch. This will increment the patch, push the new tag, and write the VERSION file. Now the artifact you build will have the right version information, every time.

You manage the major, minor patch and prerelease

When you make significant changes, you can bump the major, minor or patch number yourself with thor version:bump minor. This will create a tag with a .0 patch level, so the next build made by the server will be .1 patch level.

Auto bumping

If you include #major, #minor or #patch in the subject of commits, and run thor version:bump auto it will see if any major, minor or patch level changes are included since the last tag, and use the appropriate version. This works especially well with a CI server, allowing you to never have to directly manage versions at all. If no commits are tagged, the build number for the current version will be bumped instead.

NOTE: auto bumping currently only works for Git repos. For Perforce repos, auto is the same as build.
