#
# == Generating Parser Using Racc
#
# To compile Racc grammar file, simply type:
#
# $ racc parse.y
#
# This creates Ruby script file "parse.tab.y". The -o option can change the output filename.
#
# == Writing A Racc Grammar File
#
# If you want your own parser, you have to write a grammar file.
# A grammar file contains the name of your parser class, grammar for the parser,
# user code, and anything else.
# When writing a grammar file, yacc's knowledge is helpful.
# If you have not used yacc before, Racc is not too difficult.
#
# Here's an example Racc grammar file.
#
# class Calcparser
# rule
# target: exp { print val[0] }
#
# exp: exp '+' exp
# | exp '*' exp
# | '(' exp ')'
# | NUMBER
# end
#
# Racc grammar files resemble yacc files.
# But (of course), this is Ruby code.
# yacc's $$ is the 'result', $0, $1... is
# an array called 'val', and $-1, $-2... is an array called '_values'.
#
# See the {Grammar File Reference}[rdoc-ref:lib/racc/rdoc/grammar.en.rdoc] for
# more information on grammar files.
#
# == Parser
#
# Then you must prepare the parse entry method. 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.
