There are two types of -# parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse -# -# Racc::Parser#do_parse is simple. -# -# It's yyparse() of yacc, and Racc::Parser#next_token is yylex(). -# This method must returns an array like [TOKENSYMBOL, ITS_VALUE]. -# EOF is [false, false]. -# (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default. -# If you want to change this, see the grammar reference. -# -# Racc::Parser#yyparse is little complicated, but useful. -# It does not use Racc::Parser#next_token, instead it gets tokens from any iterator. -# -# For example, <code>yyparse(obj, :scan)</code> causes -# calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+. -# -# == Debugging -# -# When debugging, "-v" or/and the "-g" option is helpful. -# -# "-v" creates verbose log file (.output). -# "-g" creates a "Verbose Parser". -# Verbose Parser prints the internal status when parsing. -# But it's _not_ automatic. -# You must use -g option and set +@yydebug+ to +true+ in order to get output. -# -g option only creates the verbose parser. -# -# === Racc reported syntax error. -# -# Isn't there too many "end"? -# grammar of racc file is changed in v0.10. -# -# Racc does not use '%' mark, while yacc uses huge number of '%' marks.. -# -# === Racc reported "XXXX conflicts". -# -# Try "racc -v xxxx.y". -# It causes producing racc's internal log file, xxxx.output. -# -# === Generated parsers does not work correctly -# -# Try "racc -g xxxx.y". -# This command let racc generate "debugging parser". -# Then set @yydebug=true in your parser. -# It produces a working log of your parser. -# -# == Re-distributing Racc runtime -# -# A parser, which is created by Racc, requires the Racc runtime module; -# racc/parser.rb. -# -# Ruby 1.8.x comes with Racc runtime module, -# you need NOT distribute Racc runtime files. -# -# If you want to include the Racc runtime module with your parser. -# This can be done by using '-E' option: -# -# $ racc -E -omyparser.rb myparser.y -# -# This command creates myparser.rb which `includes' Racc runtime. -# Only you must do is to distribute your parser file (myparser.rb). -# -# Note: parser.rb is ruby license, but your parser is not. -# Your own parser is completely yours. -module Racc - - unless defined?(Racc_No_Extentions) - Racc_No_Extentions = false # :nodoc: - end - - class Parser - - Racc_Runtime_Version = ::Racc::VERSION - Racc_Runtime_Revision = '$Id: 1c0ef52c0f41acc465725e9e44b5b9d74d392ba5 $' - - Racc_Runtime_Core_Version_R = ::Racc::VERSION - Racc_Runtime_Core_Revision_R = '$Id: 1c0ef52c0f41acc465725e9e44b5b9d74d392ba5 $'.split[1] - begin - if Object.const_defined?(:RUBY_ENGINE) and RUBY_ENGINE == 'jruby' - require 'racc/cparse-jruby.jar' - com.headius.racc.Cparse.new.load(JRuby.runtime, false) - else - require 'racc/cparse' - end - # Racc_Runtime_Core_Version_C = (defined in extention) - Racc_Runtime_Core_Revision_C = Racc_Runtime_Core_Id_C.split[2] - unless new.respond_to?(:_racc_do_parse_c, true) - raise LoadError, 'old cparse.so' - end - if Racc_No_Extentions - raise LoadError, 'selecting ruby version of racc runtime core' - end - - Racc_Main_Parsing_Routine = :_racc_do_parse_c # :nodoc: - Racc_YY_Parse_Method = :_racc_yyparse_c # :nodoc: - Racc_Runtime_Core_Version = Racc_Runtime_Core_Version_C # :nodoc: - Racc_Runtime_Core_Revision = Racc_Runtime_Core_Revision_C # :nodoc: - Racc_Runtime_Type = 'c' # :nodoc: - rescue LoadError -puts $! -puts $!.backtrace - Racc_Main_Parsing_Routine = :_racc_do_parse_rb - Racc_YY_Parse_Method = :_racc_yyparse_rb - Racc_Runtime_Core_Version = Racc_Runtime_Core_Version_R - Racc_Runtime_Core_Revision = Racc_Runtime_Core_Revision_R - Racc_Runtime_Type = 'ruby' - end - - def Parser.racc_runtime_type # :nodoc: - Racc_Runtime_Type - end - - def _racc_setup - @yydebug = false unless self.class::Racc_debug_parser - @yydebug = false unless defined?(@yydebug) - if @yydebug - @racc_debug_out = $stderr unless defined?(@racc_debug_out) - @racc_debug_out ||= $stderr - end - arg = self.class::Racc_arg - arg[13] = true if arg.size < 14 - arg - end - - def _racc_init_sysvars - @racc_state = [0] - @racc_tstack = [] - @racc_vstack = [] - - @racc_t = nil - @racc_val = nil - - @racc_read_next = true - - @racc_user_yyerror = false - @racc_error_status = 0 - end - - # The entry point of the parser.
