end

.full_gem_path ⇒ Object

Bundler gives the tightest answer, but it is not always there: a plain ruby -e or an irb session against an installed gem has no bundle, and asking Bundler then raises instead of filtering. Falling back to every installed gem is wider than needed and still filters out the code the developer did not write.

def self.full_gem_path
  @full_gem_path ||= bundled_gem_paths || gem_install_roots
end

.gem_install_roots ⇒ Object

Without a bundle there is no resolved list to ask for, but everything installed lives under these roots, which is all the filter needs.
