Hi all, I've written a parser for Python 3.0 using Happy and Alex and I want to make it available as a library. I'd like some feedback on choosing the right module hierarchy names. I guess it is fairly clear that it should go in: Language The following document already has space for Language.Python: http://www.haskell.org/~simonmar/lib-hierarchy.html The nub of my question is really what to do about version numbers of Python? Currently my parser only supports Python 3.0. In the near future I will also support an earlier version from the 2 series. In case you don't know Python, version 3.0 is the latest version, which was released late 2008. It is not backwards compatible with earlier versions. I think it would be difficult, and probably a bad idea to try to merge a parser for Python 3.0 with a parser for an earlier version. I don't think I should use: Language.Python, since it is not clear which version of Python it is. Would it be better to have: Language.Python30 -- for version 3.0 and say: Language.Python26 -- for version 2.6 Or would it be better to have something like: Language.Python.Version30 Language.Python.Version26 In general my strategy has been to follow the structure of Language.C, but they appear to only have one version. Cheers, Bernie.
