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.
