Class Method Details

.validate(rubygems_url) ⇒ String

Validate that a resolved rubygems_url is an http(s) URL before it is used as a Gem source. The value can come from a user-writable setting or ENV, so a malformed or non-http value is rejected and replaced with the default rather than passed through to RubyGems.

Parameters:

  • the resolved rubygems source url to validate

Returns:

  • the original url if valid, otherwise DEFAULT
