Gem Version

Description

A Liquid tag plugin for Jekyll that renders a version identifier for your Jekyll site sourced from the git repository containing your code. Great if you want to display the version of your project on your site automatically each time your site is built.

Identify and highlight the build of your project by calling the tag from your Jekyll project.

This Jekyll view code will generate ...

Given a git repo with the latest tag of 3.0.0 and 5 commits since tagged, the commit ga189420 being the latest.

<p>Build: {% project_version %}</p>
This html
<p>Build: 3.0.0-5-ga189420</p>

Features

The jekyll-version-plugin has 1x feature with a few options;

Requirements

Usage

As mentioned by Jekyll's documentation you have two options; manually import the source file or require the plugin as a gem.

Require gem

Add the jekyll_version_plugin to your site _config.yml file for Jekyll to import the plugin as a gem.

gems: ['jekyll_version_plugin']

Manual import

Just download the source file into your _plugins directory, e.g.

# Create the _plugins dir if needed and download project_version_tag plugin
$ mkdir -p _plugins && cd _plugins
$ wget https://raw.githubusercontent.com/rob-murray/jekyll-version-plugin/master/lib/jekyll_version_plugin.rb

Plugin tag usage

The plugin can be called anywhere in your template with or without parameters;

{% project_version *params %}
{% project_version type format %}

Wherever you want to display the version, just add one of the snippets below in your content and the version will be rendered when the Jekyll project is built.

# Default options of `tag short`
{% project_version %} # => will run `git describe --tags --always`

# To render a short tag description like `3.0.0`
{% project_version tag short %} # => will run `git describe --tags --always`

# To render a more details tag description like `3.0.0-5-ga189420`
{% project_version tag long %} # => will run `git describe --tags --always --long`

# To render a short commitish like `151ebce`
{% project_version commit short %} # => will run `git rev-parse --short HEAD`

# To render a longer commitsh like `151ebce149c5886bcf2923db18d73742901eb976`
{% project_version commit long %} # => will run `git rev-parse HEAD`

This will simply output the version number, you can then apply your own styling as necessary. Or just html comment it out if you don't want it visible.

Output

Happy path is a git repo with releases that are tagged, if this is the case then the output will be something like this;

3.0.0 or 3.0.0-5-ga189420

If you select the commit option then the output will be something like this;

a189420

If you have selected the tags option and the repository does not have any tags then it will grab the short sha of the last commit, see above;

If for any reason this fails then the output will just be a sorry message. Sorry about that.

Sorry, could not read project version at the moment

Technical wizardry

The plugin just calls git describe or git rev-parse HEAD - For more information see git-describe and git rev-parse.

$ git describe --tags --long
$ git rev-parse --short HEAD
