LLnextgen 0.5.1 (Default branch)
LLnextgen is a (partial) reimplementation of theLLgen Extended-LL(1) parser generator that ispart of the Amsterdam Compiler Kit (ACK). It takesan EBNF-like description of the grammar withassociated semantic actions in C as input, andgenerates C code. The generated code is strictANSI C, so it should compile with all current Ccompilers.License: GNU General Public License v3Changes:
A few new warnings were added. Variables created to hold return values are now initialized.Image

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.
