This directory contains the nit parser. It is generated from a grammar for sablecc3 ( http://www.sablecc.org ).
In order to generate nit parser, you need the alternate SableCC3 generator ( http://www.mare.ee/indrek/sablecc/ ).

Contents:

	fact_parser.pl: Script used to factorize parser.nit
	Makefile: Update grammar and generate .nit files
	nit.sablecc3xx: Extended sablecc3 grammar (see prescc.sh)
	prescc.sh: Program to transform an extended sablecc3 to a standard one
	parser_nodes.nit: token and nodes classes hierarchy used by the parser and the lexer
	tables.nit, tables_nit.h: Interfaces to access the tables needed by the parser and the lexer
	test_parser.nit:
	xss/*.xss: alternate SableCC3 template files for the Nit language


The following are generated but present to avoid the need of sablecc3:

	lexer.nit: generated lexer
	parser.nit: generated parser
	parser_prod.nit: All production with generated visit methods
	tables_nit.c: The tables needed by the parser and the lexer
	parser_abs.nit: Raw generated token and nodes classes used to maintain coherence of parser_nodes.nit


Other temp files produced by the Makefile:

	.nit.sablecc3: Sablecc3 grammar after processing
	.nit.sablecc3.dump: Dump of the grammar to improve sablecc3 multiple runs
	.parser-nofact.nit: The parser generated by SableCC3 before factorization by fact_parser.pl
