I don't know enough about the required functionality to propose an API, but here goes anyway. Would be reasonable for it to have a command line that allows you to specify a package name, optionally a version string, and (very) optionally a server to contact (specified as an URL?). It should default to the highest non-experimental version that's applicable to the current Python version (assuming there's an easy way to determine this; I don't want it to try and download different versions until one works). It should not handle any kind of dependency management or package management administration. It should be able to download a Python-only module or package and install it into site-packages (or perhaps elsewhere if so directed via another optional command line flag). It should support zip, tar and tar.gz/tgz files (and perhaps tar.bz2). It should simply unpack the zip/tar file using the zip or tar modules, and extract the package/module into site-packages in such a way that it can be imported directly without messing with sys.path. It should not mess with .pth files, setup.py scripts, or eggs. If the contents of the tar/zip file has a toplevel directory with version numbers in its name (e.g. Django-0.96.1) it should skip that and just use the subdirectory whose name is the "pure" package name (e.g. django). Does this make sense? I'm happy to take push-back, this is just something I cooked up off the top of my head based on my experience with manually installing packages. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
