YAPPS(1)						      General Commands Manual							  YAPPS(1)

NAME

       yapps - create a Python module from a grammar file

SYNOPSIS

       yapps [ --dump ] [ --use-devel-grammar ] [ -fcontext-insensitive-scanner ] [ -p	pid ] [ -f ] input.g [ output.py ]  name

DESCRIPTION

	 --dump 			  Dump out grammar information
	   --use-devel-grammar		     Use the devel grammar parser from	    yapps_grammar.py instead of the stable grammar from grammar.py
	      -fcontext-insensitive-scanner    Scan all tokens (see docs)

       yapps generates a Python program which will parse a given grammar.

OPTIONS

       --dump Dump the grammar information to stdout.

       --use-devel-grammar
	      Use the grammar file in ./yapps_grammar.py instead of yapps/grammar.py.
	      This option is useful for testing new grammar parsers. (Yes, yapps' parser is itself written with yapps...)

       -fcontext-insensitive-scanner
	      Set the option to use the non-context-sensitive scanner.

CAVEATS

       yapps implements a recursive-descent scanner.

HISTORY

       Written by Amit J. Patel <amitp@cs.stanford.edu>.
       This version was enhanced by Matthias Urlichs <smurf@debian.org>.  It is not downwards-compatible with the original yapps2 (yet) and uses a
       different runtime library.
       See the change log for details.
