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

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

Methods

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.

Works like find, but finds all gemspecs matching path.

Return a list of all installed gemspecs, sorted by alphabetical order and in reverse version order. (bar-2, bar-1, foo-2)

Returns library directories glob for a gemspec. For example,

  '/usr/local/lib/ruby/gems/1.8/gems/foobar-1.0/{lib,ext}'

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

Returns files matching path in spec.
