Running the preprocessor causes differences in the repository #55

Closed Sei-Lisa closed 3 years ago

Sei-Lisa commented 3 years ago

The file pcpp/parsetab.py is re-generated when the preprocessor is run under Python 2. The generated version does not match the version present in the repository, causing differences in git diff.

This is being a problem for my project because pcpp is included as a git submodule, and it is marked as dirty.

Confirmed. Sorry about that, the ply documentation says that should never occur.

Hopefully fixed now. Let me know if it is not fixed. Thanks for the BR!

Sei-Lisa commented 3 years ago

Thanks, it appears to work now. I can't help wondering, if the file is re-generated when run, can't it be just removed from the repository, letting the installation generate it?

For those who run only from optimised bytecode python, or those using pypy or other such JIT technologies, self generation is not permitted. You can probably guess at what I want to get working next now that we no longer use eval().
