Class Method Details

.dependency(gem, version = '> 0.0.0', ret = :gem) ⇒ Object

Finds dependencies for a gem. Restrict by version with the ‘version` parameter. If `ret == :gem`, then an array of `Gem::Dependency` objects will be returned. If `ret == :raw`, then an array of arrays will be returned. Each array will have three elements: the name of the gem, its relation to the requirement `>=`, `<`, etc., and the version required (`0.4.1`, et al.)
