- How to install Python 2.0b1 on your Macintosh
- ---------------------------------------------
-
- If this is your first encounter with Python: you definitely need the
- common user documentation (common to all platforms). You can find this
- (in various forms) on www.python.org and ftp.python.org. Through
- there, or via http://www.cwi.nl/~jack/macpython.html you can also find
- the most recent MacPython distribution.
-
- Mac-specific documentation is included in this distribution in folder
- Mac:Demo. The documentation is sparse, but it will have to serve for
- now. The documentation is in HTML format, start with index.html.
-
- Caveats
- -------
- This is a beta version, so use with caution.
-
- Aside from the general new Python 2.0 features (compared to 1.5.2, there
- was no 1.6 for the macintosh) like unicode support the main new features
- of this MacPython release is support for multithreading. This has had
- some preliminary testing, but please report any success or failure on
- the mailing list.
-
- This installer installs MacPython for PowerPC only, if you really want
- 68k support you will have to stay with 1.5.2. Or, if you are willing to
- invest the time and have access to CodeWarrior you are welcome to try
- and build a 68k distribution, most of the projects and sources are
- reasonably up to date (May 2000). Contact me for details.
-
- What to install
- ---------------
-
- This installer is PPC only: too many new MacOS features are not
- available on 68K, and doing workarounds, even just #ifdeffing in the
- code, is too much work for me right now. If someone wants to revive
- 68K-MacPython: please do so. The project files still contain the 68K
- targets (they're simply skipped by the build process) so all that is
- needed is CodeWarrior, a source distribution and commitment.
-
- The optional parts in this distribution are
- - TK+PIL: Tkinter and support modules, plus Imaging, the Python image manipulation
- package (allows you to read, write and display images and do lots of operations on them).
- - img: another imaging package. Has more file format support and is faster
- than imaging, but has only limited operations on images. There is a bridge
- between the packages.
- - Numeric: the LLNL Numeric Python extension. All sorts of nifty operations
- on matrices and such. This is the most recent version from the sourceforge archive.
- - Developers kit: all header files and some tools and sample projects to get you started on
- writing Python extensions if you have CodeWarrior.
- All these except the DevKit are installed with Easy Install.
-
- After the installer finishes it automatically launches the
- ConfigurePython applet, to finish configuration of your Python.
- If you have previously installed another copy of 2.0b1 you should manually
- remove your preference file first (but no such action is needed for installing
- beside older MacPythons, and they will live together happily).
-
- If you don't have enough memory: the sizes choosen are somewhat
- arbitrary. Try lowering the application sizes in the finder "get info"
- window, and seeing whether the resulting python is still usable. Some
- modules (Tkinter comes to mind) need a lot of memory, so it may also be
- necessary to increase the application size.
-
- After installing
- ----------------
-
- It is probably a good idea to run the automatic tests. Start
- Python and "import test.autotest". This should print only 2 or 3 errors, about some
- AM/PM format not supported in strftime, about a MemoryError in test_longexp and
- about a memory error in test_zlib.
- It will, however, print some messages about optional features
- not supported. Also, if you didn't run compileall before autotesting
- you may run out of memory the first time you run the
- tests. test_socket may also fail if you have no internet
- connection. Please also read the Relnotes file for other minor
- problems with this distribution.
-
- Using Python is most easily done from the IDE, which has a builtin editor,
- debugger and other goodies. The alternative is to use PythonInterpreter,
- which is the lowlevel interpreter with a console-window only (similar to Unix
- Python).
-
- If your program uses Tkinter you MUST run it under PythonInterpreter, Tkinter
- and IDE are incompatible and your program will fail in strange ways.
-
- Uninstalling
- ------------
-
- Two items are installed in the system folder: the interpreter shared
- library "PythonCore 2.0b1" lives in the Extensions folder and the
- "Python 2.0b1 Preferences" file in the Python subfolder in the
- Preferences folder. All the rest of Python lives in the folder you
- installed in.
-
- Things to see
- -------------
-
- Start off at Mac:Demo:index.html. Read at least the first few sections.
-
- There are also some interesting files in the "Relnotes" folder that may
- contain useful information. There is also a first stab at documentation
- (plus examples) in the Mac:Demo folder. The toplevel Demo folder has
- machine-independent demos.
- The Mac:Lib:test folder also has some programs that show simple
- capabilities of various modules.
-
- The ":Mac:scripts" folder has some sample scripts. Some are useful, some are
- just interesting to look at to see how various things work. The MkDistr,
- mkapplet and fullbuild scripts (plus the ones mentioned above) may help
- you to understand how to use AppleEvents and various other toolboxes
- from python.
-
- Other mac-specific goodies can be found in :Mac:Tools, of which the IDE sources
- and a CGI framework deserve special mention.
-
- The 'img' group of modules, which handles I/O of many different image
- formats is included, but without documentation. You can find docs at
- ftp://ftp.cwi.nl/pub/jack/python/img (or somewhere around there).
-
- Finally there is a Mac:Contrib folder which contains some contributed
- software.
-
- Upgrading from older Python releases
- ------------------------------------
-
- Since release 1.4 Python releases are independent of each other, with
- separate Preferences files, shared library names, etc. The good news is
- that this means you can keep your older version around if you are unsure
- whether to upgrade. The bad news is that your old preference settings
- are lost and you have to set them again.
-
- After you are satisfied that 2.0b1 works as expected you can trash
- anything in the system folder that has "python" in the name and not
- "1.6a2".
-
- The installer
- -------------
-
- The installer for this product was created using Installer VISE
- from MindVision Software. For more information on Installer VISE,
- contact:

-
- Just van Rossum <just@letterror.nl> created the initial version of the
- installer (with Installer Vise Lite), and Jack worked from there.
-
- Thanks!
- -------
-
- Thanks go to the whole Python community with Guido in the lead, of course.
- Mac-specific thanks go to the pythonmac-sig, Just van Rossum, Corran Webster, Tony Ingraldi,
- Erik van Blokland, Bill Bedford, Chris Stern, Gordon Worley, Oliver Steele, M. Papillon,
- Steven Majewski, David Goodger, Chris Barker and all the other people who provided feedback,
- code or both!
-
- Feedback
- --------
-
- Send bug reports, suggestions, contributions and fanmail to
- <jack@cwi.nl>. However, a better way to discuss MacPython is to join the
- <pythonmac-sig@python.org> mailing list, which is explicitly meant for
- this purpose.
-
- Alternatively, you can try sending to comp.lang.python or
- python-list@cwi.nl, but since I read the newsgroup, not the mailinglist,
- I may miss it there (but other people may know quite a bit more than me
- anyway:-).
