I'm a bit confused about name quoting. I have a package with a name "Todo_SQLObject_ZPT", and egg_info writes to "Todo-SQLObject-ZPT.egg-info". Why? I thought -'s were bad, but _'s were okay...?
It's safe to use either, but setuptools considers '-' to be canonical; this was a heuristic decision on my part because '-' appears more frequently used than '_' in the names of projects currently registered with PyPI.
The problem, however, is that PyPI wants your uploaded files to *exactly* match the registered name. If you used '-' in setup.py, you must have '-' in the filename, and that's something setuptools cannot do. It would probably be best if setuptools ensured the "register" command always used '_', but then this defeats the purpose of having it that way in the first place!
So, the only real fix is to change PyPI to accept files whose pkg_resources.safe_name() match the safe_name() of the project. In the meantime, you can't upload eggs to PyPI for packages with '-' or '_' in their names. (You can upload source distros or other formats, since those can work with ambiguous filenames.) I probably should put in an RFE or proposed patch, but I've been *really* busy lately.
Richard, would you be able to make this change? It seems pretty reasonable to accept files that closely match project names.
FYI, here are the safe_name/safe_version source: def safe_name(name): """Convert an arbitrary string to a standard distribution name Any runs of non-alphanumeric characters are replaced with a single '-'. """ return re.sub('[^A-Za-z0-9]+', '-', name) def safe_version(version): """Convert an arbitrary string to a standard version string Spaces become dots, and all other non-alphanumeric characters become dashes, with runs of multiple dashes condensed to a single dash. """ version = version.replace(' ','.') return re.sub('[^A-Za-z0-9.]+', '-', version) To make an egg filename, these strings are taken and the '-' converted to a '_' so that it isn't confused with the '-' that goes between parts of the name. So given the metadata: setup( name="To-Do List", version="1.23 alpha!", ... ) The egg filename will be "To_Do_List-1.23.alpha_-py2.4-win32.egg" if generated by Python 2.4 on Windows (and it contains C extensions). Currently, if I understand it correctly, PyPI will reject this name if the name and version used for registration were "To-Do List" and "1.23 alpha!".
