Class | Gem::SourceIndex |
In: |
lib/rubygems/source_index.rb
|
Parent: | Object |
The SourceIndex object indexes all the gems available from a particular source (e.g. a list of gem directories, or a remote source). A SourceIndex maps a gem full name to a gem specification.
NOTE: | The class used to be named Cache, but that became confusing when cached source fetchers where introduced. The constant Gem::Cache is an alias for this class to allow old YAMLized source index objects to load properly. |
gems | [R] |
Factory method to construct a source index instance for a
given path.
spec_dirs: | List of directories to search for specifications. Each directory should have a "specifications" subdirectory containing the gem specifications. |
return: | SourceIndex instance |
Factory method to construct a source index instance for a given path.
deprecated: | If supplied, from_installed_gems will act just like from_gems_in. This argument is deprecated and is provided just for backwards compatibility, and should not generally be used. |
return: | SourceIndex instance |
Return a list of directories in the current gem path that contain specifications.
return: | List of directory paths (all ending in "../specifications"). |
Load a specification from a file (eval‘d Ruby code)
file_name: | [String] The .gemspec file |
return: | Specification instance or nil if an error occurs |
Constructs a source index instance from the provided specifications
specifications: | [Hash] hash of [Gem name, Gem::Specification] pairs |
Returns a Hash of name => Specification of the latest versions of each gem in this index.
Search for a gem by Gem::Dependency gem_pattern. If only_platform is true, only gems matching Gem::Platform.local will be returned. An Array of matching Gem::Specification objects is returned.
For backwards compatibility, a String or Regexp pattern may be passed as gem_pattern, and a Gem::Requirement for platform_only. This behavior is deprecated and will be removed.
