PLY is a straightforward lex/yacc implementation. Here is a list of its
|
|
|
|
|
essential features:
|
|
|
|
|
* It is implemented entirely in Python.
|
|
|
|
|
* It uses LR-parsing which is reasonably efficient and well suited for larger
|
|
|
|
|
grammars.
|
|
|
|
|
* PLY provides most of the standard lex/yacc features including support
|
|
|
|
|
for empty productions, precedence rules, error recovery, and support
|
|
|
|
|
for ambiguous grammars.
|
|
|
|
|
* PLY is straightforward to use and provides very extensive error checking.
|
|
|
|
|
* PLY doesn't try to do anything more or less than provide the basic lex/yacc
|
|
|
|
|
functionality. In other words, it's not a large parsing framework or a
|
|
|
|
|
component of some larger system.

# The README states: "You should not convert PLY using
|
|
|
|
|
# 2to3--it is not necessary and may in fact break the implementation."
|
|
|
|
|
#
|
|
|
|
|
# However, one of the example files contains python 2 "print" syntax, which
|
|
|
|
|
# lead to syntax errors during byte-compilation
|
|
|
|
|
#
|
|
|
|
|
# So we fix this file with 2to3:
|
|
|
|
|
pushd %{py3dir}
|
|
|
|
|
2to3 --write --nobackups ply/cpp.py
