Rinda error base class

Installs a gem along with all its dependencies from local and remote gems.

Raised when trying to activate a gem, and that gem does not exist on the system. Instead of rescuing from this class, make sure to rescue from the superclass Gem::LoadError to catch all types of load errors.

Raised when trying to activate a gem, and the gem exists on the system, but not the requested version. Instead of rescuing from this class, make sure to rescue from the superclass Gem::LoadError to catch all types of load errors.

Raised when removing a gem with the uninstall command fails

The installer installs the files contained in the .gem into the Gem.home.

Gem::Installer does the work of putting files in all the right places on the filesystem including unpacking the gem into its gem dir, installing the gemspec in the specifications dir, storing the cached gem in the cache dir, and installing either wrappers or symlinks for executables.

The installer invokes pre and post install hooks. Hooks can be added either through a rubygems_plugin.rb file in an installed gem or via a rubygems/defaults/#{RUBY_ENGINE}.rb or rubygems/defaults/operating_system.rb file. See Gem.pre_install and Gem.post_install for details.

An Uninstaller.

The uninstaller fires pre and post uninstall hooks. Hooks can be added either through a rubygems_plugin.rb file in an installed gem or via a rubygems/defaults/#{RUBY_ENGINE}.rb or rubygems/defaults/operating_system.rb file. See Gem.pre_uninstall and Gem.post_uninstall for details.

Gem::StreamUI implements a simple stream based user interface.

Find mis-matched syntax based on lexical count

Used for detecting missing pairs of elements each keyword needs an end, each ‘{’ needs a ‘}’ etc.

Example:

left_right = LeftRightLexCount.new
left_right.count_kw
left_right.missing.first
# => "end"

left_right = LeftRightLexCount.new
source = "{ a: b, c: d" # Note missing '}'
LexAll.new(source: source).each do |lex|
  left_right.count_lex(lex)
end
left_right.missing.first
# => "}"

This class is responsible for generating initial code blocks that will then later be expanded.

The biggest concern when guessing code blocks, is accidentally grabbing one that contains only an “end”. In this example:

def dog
  begonn # mispelled `begin`
  puts "bark"
  end
end

The following lines would be matched (from bottom to top):

1) end

2) puts "bark"
   end

3) begonn
   puts "bark"
   end

At this point it has no where else to expand, and it will yield this inner code as a block

Holds elements in a priority heap on insert

Instead of constantly calling ‘sort!`, put the element where it belongs the first time around

Example:

queue = PriorityQueue.new
queue << 33
queue << 44
queue << 1

puts queue.peek # => 44

Not a URI.

This module provides instance methods for a digest implementation object to calculate message digest values.

Used to construct C classes (CUnion, CStruct, etc)

Fiddle::Importer#struct and Fiddle::Importer#union wrap this functionality in an easy-to-use manner.

Mixin methods for install and update options for Gem::Commands

Module that defines the default UserInteraction. Any class including this module will have access to the ui method that returns the default UI.

UserInteraction allows RubyGems to interact with the user through standard methods that can be replaced with more-specific UI methods for different displays.

Since UserInteraction dispatches to a concrete UI class you may need to reference other classes for specific behavior such as Gem::ConsoleUI or Gem::SilentUI.

Example:

class X
  include Gem::UserInteraction

  def get_answer
    n = ask("What is the meaning of life?")
  end
end
