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.

Usage

current_version

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

version_of

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

Installation

Add this line to your application's Gemfile:

gem 'gersion'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gersion
