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.
