A few notes:
1. The cpp.py file requires the use of generators and generator
expressions which were not supported in Python 2.3.4. Since
this file is still experimental, I'll probably remove it from
the main release.
2. The cryptic warning about sys.maxint is due to a change in
calculating signatures. PLY-3.0 is simply calculating a
CRC32 checksum instead of using an MD5 hash. I don't
actually see that warning message on my machine, but I'm
not using Python 2.3 either. I'm open to ideas on whether
or not PLY should go back to using MD5 hashes.
3. I will look at the nowarn argument to lex again and see if I
want to add it back. As a general rule, I'm trying to shift
output from PLY away from magic flag settings and towards
the use of the logging module.
4. I'll check on the debug flag behavior for yacc. That's probably
something that should be restored.
Cheers,
Dave
Hello,
> I would appreciate feedback from current PLY users
I can get it to work. However, I do have a few issues:
- I use Python 2.3.4 and get the following during installation:
byte-compiling XXX/.local/lib/python2.3/site-packages/ply/cpp.py to
cpp.pyc
File "XXX/.local/lib/python2.3/site-packages/ply/cpp.py", line 742
filename = "".join(x.value for x in tokens[1:i])
^
SyntaxError: invalid syntax
and:
byte-compiling XXX/.local/lib/python2.3/site-packages/ply/yacc.py to
yacc.pyc
XXX/.local/lib/python2.3/site-packages/ply/yacc.py:2720: FutureWarning:
hex/oct constants > sys.maxint will return positive values in Python 2.4
and up
return sig & 0xffffffff
- I use the 'nowarn' parameter for lex.lex(...) and now I get:
TypeError: lex() got an unexpected keyword argument 'nowarn'
since that argument was removed. I tried to supply errorlog=lex.NullLogger()
instead, which seems to work.
- I had to supply errorlog=yacc.NullLogger() to yacc.yacc(...) to make
sure "Generating LALR tables" was not printed. It did not get printed
in Ply 2.5 (for debug=0). I think this is what Andrew (apwaters) already
replied. I don't think the message indicates an error, so I don't think
it should be printed if debug=0.
