No one has said anything about the applet packaging concept as we discuss moving forward with this stuff. I'm assuming that this is because the tools based on WASTE aren't going to be ported (such as applet builder), and also because applet is part of Bundlebuilder, which has been deprecated in favor of py2app. However, the applet method is really an easy way to package apps that have the external dependencies already installed on one's machine: I always use the buildapplet.py script that came with the older MacPython distributions. This is a good use case for IDLE, as its dependencies (tkinter) come by default on the Mac. Using py2app or its variants would be overkill here.

This is a very good reason for not pointing newbies to the system python on pythonmac.org: unless anyone steps up to *seriously* support the system python there won't be properly packages extension packages for the system python. My concern would be that someone steps up with the noble intent of supporting a large number of repackagings, only for their enthusiasm to wear off after a few months after they realise how much long-term work they've committed themselves to. (i.e. Don't bite off more than you can chew.) The sensible thing would probably be to work out what the dozen most-used 3rd-party packages for casual users are likely to be, and commit to maintaining pkgs those for the next year or two. A modest number like that shouldn't create too onerous a workload; enough for the default Python to keep casual users happy without turning into an excessive duplication of effort. e.g. I'm happy to continue providing both 2.3 and 2.4 binary installers for appscript as it's no more work for me, so that's one of the dirty dozen covered right there. As has been said elsewhere, if the aim is to market Python to a broad audience then it's at least as much an exercise in influencing perceptions as technical merit. And often folk just don't like to be presented with a long list of things to download and install before they're able to do anything. e.g. Back before Nick stepped in with his all-in-one installer, some folks fair moaned about having to install a half-dozen simple distutils packages in order to use appscript. Even though the latter approach only took an extra minute or two in practice, in the end it was simpler and much more effective to cater to their unreasonable demands than lecture them on why they were wrong. Like I say, perceptions count. And first impressions more than anything else. Technical arguments alone aren't enough; things have to *look* and *sound* simple too.

The way that Python is used in such an environment is closer to how it is used on a Linux or BSD distribution, given that it has managed packages and is only usable from a shell.

And for your purposes, these are completely legitimate complaints. I'd say pragmatic, not parochial. I understand your concerns but why should we spend our precious and limited resources bothering with a Python distribution that can only support a subset of uses. If we ignore the vendor's interpreter then our documentation becomes MUCH simpler as there will be one -- and preferably only one -- way to do it: install a Python interpreter that is recent and can run the full scope of Python applications. We also get to ignore the issues of which version of Mac OS X they are using because 10.3 and 10.4 will behave the same, and we have the opportunity to fix the issues that constantly plague users such as python vs pythonw (we can simply make the symlinks in /usr/local/bin both point at pythonw). But there are lots of pure Unix programs which it works quite well for. I do a lot of text processing, web-page re-writing, web spidering, etc. which works fine with the pre-installed Python. I do image0-processing with PIL and PDF generation with ReportLab which works fine. And to not support -- even celebrate -- those uses is, IMO, self-defeating. Sure, but all of that stuff works even better with a newer distribution of Python due to enhancements in the interpreter. There's no disadvantage to glossing over the fact that there is an interpreter that ships with OS X. The minimal effort it takes to use a third party installation of Python is well worth it, and it becomes more useful as time goes on. Doubly so now that Leopard is approaching, because users can upgrade without losing all of their Python work to major version upgrade death. To begin with, I don't see a stability in the current state of MacPython that gives me confidence in this assurance. But I agree that the effort of installation is minimal, and should be encouraged. Right now, the current state of MacPython is effectively the current state of Python itself. If you don't trust Python 2.4, how do you trust Python 2.3? Given Apple's track record of making Python worse (though they are consistently improving), your viewpoint makes no sense to me. Should we officially encourage Apple not to include Python in their next release? That would solve lots of these problems, I think. Our problem with Apple's bundling of Python is purely a documentation issue (and the stubbornness of those who insist that it should be used -- even celebrated -- despite its disadvantages). If we make the proposed PATH change script to the installer, we can ignore the system Python just as easily as we could if it wasn't there at all. There's little good reason for us to petition for its removal, and there's good reason for them to keep it there: they use it. -bob ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

Great idea, Rodney. I think we probably need a number of pages like this, kind of an FAQ set. I think the main page should just cover one or two things (how to run python, how to upgrade), and lots of pointers to these pages. Each of these should be fairly clear, with pointers off to more complicated explanations. Here's the start of a list: 1) What's the difference between python and pythonw? 2) What's the advantage of upgrading? 3) What do I do if I want to use pre-built packages? 4) How do I use the Apple GUI toolkit from Python? 5) How do I use Apple Events from Python? 6) How do I build a real Mac application written in Python? 7) How do I install extra modules, like PIL, for the system Python? 8) What IDE's are available, and what are their relative merits?

The largest issue is that you can't legally redistribute the Python interpreter that ships with Mac OS X, so you can't create standalone applications. Even if you could, it wouldn't have a chance of being backwards compatible with the way that Apple builds things. Semi-standalone applications are fragile and only work on a particular minor version of OS X... for example, anything you build against it is only compatible with Mac OS X 10.4. It won't be compatible with Mac OS X 10.3, and it won't be compatible with Mac OS X 10.5 or anything farther away in either direction. Using a third party Python has a chance of being backwards compatible (some apps built on 10.4 work on 10.3) and it virtually guarantees forwards compatibility (apps I built standalone with py2app on 10.2 still work on 10.4, even with i386 hardware). -bob ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

Now click on the finder and open the folder you want Terminal to access. In the titlebar of the finder window, next to the folder's name, is a little folder icon. Drag that icon to your terminal window (Expose helps if you have lots of windows open). Terminal will spell out the folder's path for you. Now return to Terminal and hit enter.

That would make a big difference.

Kevin Ollivier wrote: I'd get really pissed off if I didn't know better and things stopped working regardless of how I upgraded Python. You'd consider whose Python broke your stuff into your decision to get upset? We really seem to be talking at cross purposes here. If I upgrade *python*, I expect things that depend on it to break, though in fact, when I upgrade python, I usually leave the old version in place so that nothing breaks. I put a version in my #! lines just for that reason. However, when I upgrade OS-X, I want my currently installed apps to keep working. And, in fact, they do, except the ones that depend on python. I just upgraded to OS-X 10.4. For ages, I've been using both Apples python2.3 and Bob's 2.4. All my scripts that have #!/usr/bin/env python2.3 in them are now broken. All the scripts that have #!/usr/bin/env python2.4 in them still work. If I'd started with 2.4 from the beginning, nothing would have broken. It's not hard to fix, particularly since I have a fully functional 2.4 already, but I'm not a newbie, either. All Apple is doing is including Python with their OS, and occasionally updating it. That these updates can cause not-so-pleasant things to happen due to how Python works is not Apple's fault. A lot of the speech on here practically accuses Apple of causing the problem and it's really not fair. What they are doing is analogous to removing a bunch of shared libraries when you did an OS upgrade. IF you knew they were likely to do that you'd darn well better statically link your apps. tell them things break when Python is upgraded to a new major version; don't tell them (or suggest) things break because Apple is doing it. Tell them that Apple is likely to upgrade python for you when you upgrade the OS, whether you want them to or not. however -- that's all we're saying. What about an app bundle that just starts IDLE? Yes, we should make one of those! Kevin Walzer wrote: No one has said anything about the applet packaging concept as we discuss moving forward with this stuff.

Could a Mac ever ship with an acceptable pre-installed Python? If not, perhaps the solution for Apple is to move /usr/bin/python to some other spot, like /usr/libexec/, or some such place. The issue of not being able to produce redistributable applications still exists, and also backwards compatibility with previous versions of Mac OS X. So you're saying that the pre-installed version could never be really acceptable. In that case, perhaps we only need convince Apple to move /usr/bin/python to some more system-y place that wouldn't usually be on users' paths. We then in the MacPython world take the position that Python isn't really pre-installed on Macs, and the place for a person to start would be to download the installer and run it. Perhaps then in addition the installer could symlink /usr/local/bin/pythonw to /usr/bin/python, thereby solving the PATH issue.

It might be a good idea to highlight the really frequent FAQs and link to their answers on the wiki. I think this would be a pretty good way to start building a FAQ. There already is a FAQ, and it's been there for a very long time. We don't have to start building anything -- just link to the most popular ones. -bob ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

If not, perhaps the solution for Apple is to move /usr/bin/python to some other spot, like /usr/libexec/, or some such place. The issue of not being able to produce redistributable applications still exists, and also backwards compatibility with previous versions of Mac OS X. So you're saying that the pre-installed version could never be really acceptable. In that case, perhaps we only need convince Apple to move /usr/bin/python to some more system-y place that wouldn't usually be on users' paths. We then in the MacPython world take the position that Python isn't really pre-installed on Macs, and the place for a person to start would be to download the installer and run it. Perhaps then in addition the installer could symlink /usr/local/bin/pythonw to /usr/bin/python, thereby solving the PATH issue. That's not an acceptable solution. We need to support versions of OS X that currently exist, and we can't depend on Apple to do anything. -bob ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
[Pythonmac-SIG] strange #!/usr/bin/pythonw behavior...
I want to manipulate iCal from the command line. Thanks to appscript it looks like I'll be able to do what I want. I wrote a simple skeleton script: #!/usr/bin/pythonw %(prog)s - manipulate iCal import sys import os import getopt from appscript import * ... etc ... I made it executable and tried executing it from the bash prompt in a Terminal window. No go. The system treats it like a shell script and passes it off to the Bourne shell. Naturally, this doesn't go over too well. If I run it as /usr/bin/pythonw ical.py ... it works just fine. Am I missing something?

If you happen to use the system Python, then you will produce a package that only runs on the particular release of Mac OS X that you build it with. In other words, when you or your users upgrade to Mac OS X 10.5, any system-Python built application bundle will cease to function at all. It is actually not much different than on other platforms. Many py2exe-based setup scripts work identically with py2app if you change the import statement. Mac-specific features of course require Mac- specific solutions, but the standard stuff is identical. There is some minimal documentation: http://undefined.org/python/ py2app.html In general, I know this. I try to at least skim the messages on this list on a regular basis to keep up with what is going on in the MacPython world. But, for someone who is new to Python, the documentation you are pointing to is pretty rough going. It would be really nice to have a more basic introduction to what py2app actually does. Then, a step by step description of how to make it work, rather than just jumping into setup.py scripts. (Where does setup.py come from? The documentation doesn't say. I'm not asking this, just pointing out that it will be confusing to someone just trying to learn this stuff. They are going to want to know why they have to build their application when they already have it running.) Any other questions you have can probably be answered by py2exe documentation and/or this list. Yes, I'm sure they can be. I don't see any reference to actually taking a look at the py2exe documentation. Everything states that it is similar, but for the Mac. It doesn't say take a look there if you need more help. Or to ask here. But this discussion is about how to make this easier for people to get into. Having to ask here isn't that bad. Everyone here is very friendly and helpful. But, many people don't like to subscribe to mailing lists, especially to ask one question. Most of the discussions that go on here are *WAY* over the heads of beginners and even many intermediate Python users. And, the answers often times make assumptions about what the user knows rather than offering basic advice. I'm not complaining, really. I know that you and everyone here do this on your own time and do your best to help everyone. Python on the Mac really needs a very easily accessible discussion board for people to read and ask questions. python-mac is intimidating to someone getting started. Those who aren't so timid may stick it out, but many people will likely skim the messages on the python.org website and walk away after deciding that this stuff is just too tough. The ones who are already programmers aren't the ones I'm talking about. I'm more talking about the new scripter or maybe someone who has done a little bit of AppleScript or possibly HTML and basic JavaScript. While I can articulate what I want to see and can put myself in the place of the absolute beginner (I'm not too far from that myself with Python and I teach technical courses to varying skill levels of users for a living), I unfortunately don't have the Python background to write this material myself. I hope this helps get across what I'm looking for and what I think will benefit people trying to get started with Python on the Mac. -Rodney ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

You need to point it at the actual binary: /System/Library/Frameworks/Python.framework/Versions/2.3/Resources/ Python.app/Contents/MacOS/Python If you upgrade to 10.4, this should work. -bob ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
