I just checked in a couple of new features for EasyInstall that some of you will be interested in.
First, '.' is now allowed in project names, and '_' and '-' in names should no longer confuse EasyInstall when it searches PyPI. It will use whatever characters you originally entered.
The bad news is that this could break any existing dependencies to projects with a '.' in their names, because the '.' was being converted to '-' before, and isn't now. The good news is that there are only 5 PyPI projects with a '.' in the name (rsync.py, spider.py, _sre.py, zope.interface, and zope.testbrowser), and of them only '_sre.py' had a prayer of working with EasyInstall before.
Now, 'spider.py' also works due to the next new feature, which is that installation of bare '.py' files (no accompanying setup.py) is now supported. If a PyPI "Download URL" points to a file with a .py extension, EasyInstall will automatically create a proper setup.py alongside it. It can also do this for any link to a .py file that includes an '#egg=name-version' fragment identifier, so that you can use a link like this:
to point to somebody's .py file and assign it a project name and version. Note that the '#egg' tag must be *unambiguous*, which means you cannot have a '-' in the project name or version. You must escape them as '_' characters, using the '-' only to delimit the name from the version. Anyway, if you do this on *your* project's PyPI page to link to your project's unpackaged dependencies, you can fill in for the dependency's lack of a PyPI page or setup script, while still using the normal setuptools way of specifying project dependencies.
Please let me know if you have any questions or problems using these new features. Thanks!
