|
# Converts a UNIX-yacc specification file into a PLY-compatible
|
|
# specification. To use, simply do this:
|
|
#
|
|
# % python yply.py [-nocode] inputfile.y >myparser.py
|
|
#
|
|
# The output of this program is Python code. In the output,
|
|
# any C code in the original file is included, but is commented.
|
|
# If you use the -nocode option, then all of the C code in the
|
|
# original file is discarded.
|
|
#
|
|
# Disclaimer: This just an example I threw together in an afternoon.
|
|
# It might have some bugs. However, it worked when I tried it on
|
|
# a yacc-specified C++ parser containing 442 rules and 855 parsing
|
|
# states.
