Gersion

Look up the version of your Ruby application and any Ruby gems.

This gem assumes and requires the common Ruby setup, like:

• Your project uses git,
• Your server has git installed (no Heroku?), and
• You use Bundler with a Gemfile.lock file in your app's root.

The idea is that you could create a way to report back this information in your application... like a SHA key in the footer of your web app's HTML.

We'll consider the "current version" of your application as your git repo's HEAD. If it's tagged, the tag will be treated as the version.

# my git HEAD is tagged as 1.2.3
Gersion.current_version # <= 1.2.3

If there is no tag, then it will report back the HEAD sha key.

# my git HEAD is 9760260978ce5c68a319500509205654af4a6c9d
Gersion.current_version # <= 9760260978ce5c68a319500509205654af4a6c9d

You may want to report back specific versions of gems that your application uses.

Say you want to see which version of Rails your web application runs:

Gersion.version_of('rails') # <= 4.1.2

If your gem is pointed at a specific tag on a git repo, that will be reported:

# my special gem is pointing at the 1.2.3 tag
Gersion.version_of('my_special_gem') # <= 1.2.3

If your gem is pointed at a git repo with no tag, that will be reported as well:

# my special gem is pointing at the 87e7fae05aa289ab40326d0d162a7913f4a0ca59 sha
Gersion.version_of('my_special_gem') # <= 87e7fae05aa289ab40326d0d162a7913f4a0ca59

Add this line to your application's Gemfile:

gem 'gersion'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gersion
