Public Instance Methods
Adds spec
to the the record, keeping the collection properly sorted.
# File lib/rubygems/specification_record.rb, line 78 def add_spec(spec) return if all.include? spec all << spec stubs << spec (@stubs_by_name[spec.name] ||= []) << spec Gem::Specification._resort!(@stubs_by_name[spec.name]) Gem::Specification._resort!(stubs) end
Returns the list of all specifications in the record
# File lib/rubygems/specification_record.rb, line 32 def all @all ||= Gem.loaded_specs.values | stubs.map(&:to_spec) end
Sets the specs known by the record to specs
.
# File lib/rubygems/specification_record.rb, line 101 def all=(specs) @stubs_by_name = specs.group_by(&:name) @all = @stubs = specs end
Return full names of all specs in the record in sorted order.
# File lib/rubygems/specification_record.rb, line 109 def all_names all.map(&:full_name) end
Enumerate every known spec.
# File lib/rubygems/specification_record.rb, line 118 def each return enum_for(:each) unless block_given? all.each do |x| yield x end end
Return the best specification in the record that contains the file matching path
, among those already activated.
# File lib/rubygems/specification_record.rb, line 173 def find_active_stub_by_path(path) stub = @active_stub_with_requirable_file[path] ||= stubs.find do |s| s.activated? && s.contains_requirable_file?(path) end || NOT_FOUND stub.this end
Returns every spec in the record that matches name
and optional requirements
.
# File lib/rubygems/specification_record.rb, line 129 def find_all_by_name(name, *requirements) req = Gem::Requirement.create(*requirements) env_req = Gem.env_requirement(name) matches = stubs_for(name).find_all do |spec| req.satisfied_by?(spec.version) && env_req.satisfied_by?(spec.version) end.map(&:to_spec) if name == "bundler" && !req.specific? require_relative "bundler_version_finder" Gem::BundlerVersionFinder.prioritize!(matches) end matches end
Return the best specification in the record that contains the file matching path
.
# File lib/rubygems/specification_record.rb, line 148 def find_by_path(path) path = path.dup.freeze spec = @spec_with_requirable_file[path] ||= stubs.find do |s| s.contains_requirable_file? path end || NOT_FOUND spec.to_spec end
Return the best specification in the record that contains the file matching path
amongst the specs that are not activated.
# File lib/rubygems/specification_record.rb, line 161 def find_inactive_by_path(path) stub = stubs.find do |s| next if s.activated? s.contains_requirable_file? path end stub&.to_spec end
Return the latest installed spec in the record for gem name
.
# File lib/rubygems/specification_record.rb, line 192 def latest_spec_for(name) latest_specs(true).find {|installed_spec| installed_spec.name == name } end
Return the latest specs in the record, optionally including prerelease specs if prerelease
is true.
# File lib/rubygems/specification_record.rb, line 185 def latest_specs(prerelease) Gem::Specification._latest_specs stubs, prerelease end
Removes spec
from the record.
# File lib/rubygems/specification_record.rb, line 92 def remove_spec(spec) all.delete spec.to_spec stubs.delete spec (@stubs_by_name[spec.name] || []).delete spec end
Returns a Gem::StubSpecification
for every specification in the record
# File lib/rubygems/specification_record.rb, line 39 def stubs @stubs ||= begin pattern = "*.gemspec" stubs = stubs_for_pattern(pattern, false) @stubs_by_name = stubs.select {|s| Gem::Platform.match_spec? s }.group_by(&:name) stubs end end
Returns a Gem::StubSpecification
for every specification in the record named name
only returns stubs that match Gem.platforms
# File lib/rubygems/specification_record.rb, line 53 def stubs_for(name) if @stubs @stubs_by_name[name] || [] else @stubs_by_name[name] ||= stubs_for_pattern("#{name}-*.gemspec").select do |s| s.name == name end end end
Finds stub specifications matching a pattern in the record, optionally filtering out specs not matching the current platform
# File lib/rubygems/specification_record.rb, line 67 def stubs_for_pattern(pattern, match_platform = true) installed_stubs = installed_stubs(pattern) installed_stubs.select! {|s| Gem::Platform.match_spec? s } if match_platform stubs = installed_stubs + Gem::Specification.default_stubs(pattern) Gem::Specification._resort!(stubs) stubs end
