Eggs exist and py2app should support them, otherwise people have to resort to ugly workarounds like copying files manually. Adding an option for copying a set of eggs into the application bundle would be fairly easy. > > I've dealt with this for an app that was heavily dependent on setuptools > features like pkg_resources, and I think setuptools is really pretty ugly, at > least when you want to use things like py2app and friends. > > The assumption that you're packages are fully installed as part of a nice big > python install is really built in, so the only solution is to copy huge > chunks of stuff, much of which you don't need, into your app bundle -- > whether py2app does this automatically, or you do it in your scripts, it's > still a lot of extra stuff. That can be a problem, especially with older codebases that haven't been split into a number of smallish packages. > > Personally, I like setuptools for install time stuff, but not so much for run > time stuff -- if you can avoid run time calls to setuptolls, I would. > > AS for resources, personally I like to use python files for data -- and then > "import" to get it - this makes for nice, clean integeration with py2app, etc. I use python files for resources on Windows to get single-file executables with py2exe, but prefer to use real data files on OSX for easier maintenance.
