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 <[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.
