version_reader

Small Gem to read your version file.

Assuming you have a file ~/CoolApp/VERSION with the content of 0.4.2\n.

require 'version_reader'

version_reader = VersionReader.new('~/CoolApp/VERSION')
version_reader.normal # 0.4.2

If you add this gem to your Gemfile of a Rails application it will automatically define CoolApp::Application.version and fill in a Rails-flavored VersionReader instance.

Flavors are an easy way to extend a VersionReader object with additional informations.

The Rails flavor adds some additional methods which also show some information about the current Rails-Environment.

Always adds the current Rails-Environment to the version. Maybe useful to see whether this is staging or not :)

CoolApp::Application.version.rails_env

Output would be 0.4.2-development.

Adds the current Rails-Environment if it does not match one of the given environments.

CoolApp::Application.version.rails_env_without(:production,:staging)

Output would be 0.4.2-development or 0.4.2 for staging and production.
