Method: Bundler::GemVersionPromoter#sort_versions

Defined in:
lib/bundler/gem_version_promoter.rb

#sort_versions(package, specs) ⇒ Specification

Given a Resolver::Package and an Array of Specifications of available versions for a gem, this method will return the Array of Specifications sorted in an order to give preference to the current level (:major, :minor or :patch) when resolution is deciding what versions best resolve all dependencies in the bundle.

Parameters:

  • package (Resolver::Package) —

    The package being resolved.

  • specs (Specification) —

    An array of Specifications for the package.

Returns:

  • (Specification) —

    A new instance of the Specification Array sorted.
