YAML is optimized for data serialization, formatted -# dumping, configuration files, log files, Internet messaging and -# filtering. This specification describes the YAML information model and -# serialization format. Together with the Unicode standard for characters, it -# provides all the information necessary to understand YAML Version 1.0 -# and construct computer programs to process it. -# -# See http://yaml.org/ for more information. For a quick tutorial, please -# visit YAML In Five Minutes (http://yaml.kwiki.org/?YamlInFiveMinutes). -# -# == About This Library -# -# The YAML 1.0 specification outlines four stages of YAML loading and dumping. -# This library honors all four of those stages, although data is really only -# available to you in three stages. -# -# The four stages are: native, representation, serialization, and presentation. -# -# The native stage refers to data which has been loaded completely into Ruby's -# own types. (See +YAML::load+.) -# -# The representation stage means data which has been composed into -# +YAML::BaseNode+ objects. In this stage, the document is available as a -# tree of node objects. You can perform YPath queries and transformations -# at this level. (See +YAML::parse+.) -# -# The serialization stage happens inside the parser. The YAML parser used in -# Ruby is called Syck. Serialized nodes are available in the extension as -# SyckNode structs. -# -# The presentation stage is the YAML document itself. This is accessible -# to you as a string. (See +YAML::dump+.) -# -# For more information about the various information models, see Chapter -# 3 of the YAML 1.0 Specification (http://yaml.org/spec/#id2491269). -# -# The YAML module provides quick access to the most common loading (YAML::load) -# and dumping (YAML::dump) tasks. This module also provides an API for registering -# global types (YAML::add_domain_type). -# -# == Example -# -# A simple round-trip (load and dump) of an object. -# -# require "yaml" -# -# test_obj = ["dogs", "cats", "badgers"] -# -# yaml_obj = YAML::dump( test_obj ) -# # -> --- -# - dogs -# - cats -# - badgers -# ruby_obj = YAML::load( yaml_obj ) -# # => ["dogs", "cats", "badgers"] -# ruby_obj == test_obj -# # => true -# -# To register your custom types with the global resolver, use +add_domain_type+. -# -# YAML::add_domain_type( "your-site.com,2004", "widget" ) do |type, val| -# Widget.new( val ) -# end -# module YAML + class EngineManager # :nodoc: + attr_reader :yamler - Resolver = YAML::Syck::Resolver - DefaultResolver = YAML::Syck::DefaultResolver - DefaultResolver.use_types_at( @@tagged_classes ) - GenericResolver = YAML::Syck::GenericResolver - Parser = YAML::Syck::Parser - Emitter = YAML::Syck::Emitter - - # Returns a new default parser - def YAML.parser; Parser.new.set_resolver( YAML.resolver ); end - - # Returns a new generic parser - def YAML.generic_parser - warn "#{caller[0]}: YAML.generic_parser is deprecated, switch to psych" if $VERBOSE - Parser.new.set_resolver( GenericResolver ) - end - - # Returns the default resolver - def YAML.resolver - warn "#{caller[0]}: YAML.resolver is deprecated" if $VERBOSE - DefaultResolver - end - - # Returns a new default emitter - def YAML.emitter - warn "#{caller[0]}: YAML.emitter is deprecated" if $VERBOSE - Emitter.new.set_resolver( YAML.resolver ) - end - - # - # Converts _obj_ to YAML and writes the YAML result to _io_. - # - # File.open( 'animals.yaml', 'w' ) do |out| - # YAML.dump( ['badger', 'elephant', 'tiger'], out ) - # end - # - # If no _io_ is provided, a string containing the dumped YAML - # is returned. - # - # YAML.dump( :locked ) - # #=> "--- :locked" - # - def YAML.dump( obj, io = nil ) - obj.to_yaml( io || io2 = StringIO.new ) - io || ( io2.rewind; io2.read ) - end - - # - # Load a document from the current _io_ stream. - # - # File.open( 'animals.yaml' ) { |yf| YAML::load( yf ) } - # #=> ['badger', 'elephant', 'tiger'] - # - # Can also load from a string. - # - # YAML.load( "--- :locked" ) - # #=> :locked - # - def YAML.load( io ) - yp = parser.load( io ) - end - - # - # Load a document from the file located at _filepath_. - # - # YAML.load_file( 'animals.yaml' ) - # #=> ['badger', 'elephant', 'tiger'] - # - def YAML.load_file( filepath ) - File.open( filepath ) do |f| - load( f ) - end - end - - # - # Parse the first document from the current _io_ stream - # - # File.open( 'animals.yaml' ) { |yf| YAML::load( yf ) } - # #=> #<YAML::Syck::Node:0x82ccce0 - # @kind=:seq, - # @value= - # [#<YAML::Syck::Node:0x82ccd94 - # @kind=:scalar, - # @type_id="str", - # @value="badger">, - # #<YAML::Syck::Node:0x82ccd58 - # @kind=:scalar, - # @type_id="str", - # @value="elephant">, - # #<YAML::Syck::Node:0x82ccd1c - # @kind=:scalar, - # @type_id="str", - # @value="tiger">]> - # - # Can also load from a string. - # - # YAML.parse( "--- :locked" ) - # #=> #<YAML::Syck::Node:0x82edddc - # @type_id="tag:ruby.yaml.org,2002:sym", - # @value=":locked", @kind=:scalar> - # - def YAML.parse( io ) - yp = generic_parser.load( io ) - end - - # - # Parse a document from the file located at _filepath_. - # - # YAML.parse_file( 'animals.yaml' ) - # #=> #<YAML::Syck::Node:0x82ccce0 - # @kind=:seq, - # @value= - # [#<YAML::Syck::Node:0x82ccd94 - # @kind=:scalar, - # @type_id="str", - # @value="badger">, - # #<YAML::Syck::Node:0x82ccd58 - # @kind=:scalar, - # @type_id="str", - # @value="elephant">, - # #<YAML::Syck::Node:0x82ccd1c - # @kind=:scalar, - # @type_id="str", - # @value="tiger">]> - # - def YAML.parse_file( filepath ) - File.open( filepath ) do |f| - parse( f ) - end + def initialize + @yamler = nil end - # - # Calls _block_ with each consecutive document in the YAML - # stream contained in _io_. - # - # File.open( 'many-docs.yaml' ) do |yf| - # YAML.each_document( yf ) do |ydoc| - # ## ydoc contains the single object - # ## from the YAML document - # end - # end - # - def YAML.each_document( io, &block ) - warn "#{caller[0]}: YAML.each_document is deprecated" if $VERBOSE - yp = parser.load_documents( io, &block ) + def syck?
