Class Gem::GemPathSearcher
In: lib/rubygems/custom_require.rb
Parent: Object

GemPathSearcher has the capability to find loadable files inside gems. It generates data up front to speed up searches later.

Methods

find   matching_file   new  

Public Class methods

Initialise the data we need to make searches later.

Public Instance methods

Look in all the installed gems until a matching path is found. Return the gemspec of the gem where it was found. If no match is found, return nil.

The gems are searched in alphabetical order, and in reverse version order.

For example:

  find('log4r')              # -> (log4r-1.1 spec)
  find('log4r.rb')           # -> (log4r-1.1 spec)
  find('rake/rdoctask')      # -> (rake-0.4.12 spec)
  find('foobarbaz')          # -> nil

Matching paths can have various suffixes (’.rb’, ’.so’, and others), which may or may not already be attached to file. This method doesn‘t care about the full filename that matches; only that there is a match.

Private Instance methods

Attempts to find a matching path using the require_paths of the given spec.

Some of the intermediate results are cached in @lib_dirs for speed.
