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.
