How to install Python 2.0 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.pythonlabs.com, 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 final candidate version, so use with caution, and please report
|
|
problems as soon as possible, to pythonmac-sig@python.org.
|
|
|
|
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.
|
|
|
|
This version of Python expects a recent version of Appearance, so it may
|
|
be that users with pre MacOS 8.5 systems have trouble running it. If
|
|
that is the case try getting CarbonLib from Apple, I am told this
|
|
includes Appearance and NavServices. You may also have to disable the
|
|
"Use navservices" preference for best results.
|
|
|
|
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 2.0 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).
|
|
|
|
Moving your Python installation after installing is generally not a good idea.
|
|
If you have to do this anyway you should remove your preference file, run
|
|
ConfigurePython and remove all .pyc files.
|
|
|
|
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".
|
|
|
|
Three tests will fail on the mac, all with MemoryErrors: test_sha,
|
|
test_longexp and test_zlib. If you increase the PythonInterpreter memory
|
|
partition size they will pass. It will, however, print some messages
|
|
about optional features not supported. You should not worry about these,
|
|
they are modules that are supported by Python on other platforms. 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 2.0" lives in the Extensions folder and the
|
|
"Python 2.0 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 2.0 works as expected you can trash
|
|
anything in the system folder that has "python" in the name and not
|
|
"2.0".

|
installer (with Installer Vise Lite), and Jack worked from there.

|
course. Mac-specific thanks go to the pythonmac-sig, Just van Rossum,

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:-).
