SYNOPSISyapps [ --dump ] [ --use-devel-grammar ] [ -fcontext-insensitive-scanner ] [ -p pid ] [ -f ] input.g [ output.py ] name
--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.
- Dump the grammar information to stdout.
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...)
- Set the option to use the non-context-sensitive scanner.
CAVEATSyapps implements a recursive-descent scanner.
HISTORYWritten by Amit J. Patel <[email protected]>.
This version was enhanced by Matthias Urlichs <[email protected]>. It is not downwards-compatible with the original yapps2 (yet) and uses a different runtime library.
See the change log for details.
