This is a MacPython that can run on classic MacOS (from 8.1
|
2001-03-06 22:42:12 +00:00
|
|
|
onwards) and natively on MacOSX. The installer tries to work out whether you can
|
2001-12-20 20:41:45 +00:00
|
|
|
use the Carbon version or not. For Mac OS X users: this version of Python
|
|
|
|
does not run from the command line, it is a pure "Mac only" app. Use the standard
|
|
|
|
unix Python from the commandline, the two Pythons will be merged in the future.

2001-08-29 22:04:08 +00:00
|
|
|
You should definitely read the Relnotes file too, and the section below about
|
2001-10-23 22:22:09 +00:00
|
|
|
toolbox module reorganization. You should also read :Misc:NEWS, which lists
|
|
|
|
the general (non-mac-dependent) new features of this Python release.

|
|
|
A special note about the active installer: do not background it, it may hang
|
2001-03-27 21:38:55 +00:00
|
|
|
your machine. This is a general problem with Vise active installers, MindVision
|
|
|
|
are working on it.

If this is your first encounter with Python: you definitely need the
|
|
|
|
common user documentation (common to all platforms). You can find this
|
2000-10-19 21:58:27 +00:00
|
|
|
(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.
|
1997-08-26 13:25:06 +00:00
|
|
|
|
|
|
|
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.
|
|
|
|

2001-03-06 22:42:12 +00:00

|
This installer installs MacPython for classic PPC MacOS, MacPython for Carbon
|
2001-12-27 23:01:18 +00:00
|
|
|
(OS X, OS 9 or OS 8 with CarbonLib installed) or both, depending on your
|
2001-03-06 22:42:12 +00:00
|
|
|
configuration. By selecting custom install you can bypass these tests and
|
|
|
|
install what you want.
|
1998-01-06 12:13:16 +00:00
|
|
|
|
2001-12-27 23:01:18 +00:00
|
|
|
If you want 68k support you will have get MacPython 1.5.2.

What to install
|
|
|
|
---------------
|
|
|
|
|
2000-05-06 23:01:07 +00:00
|
|
|
The optional parts in this distribution are
|
2001-10-31 10:13:52 +00:00
|
|
|
- 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).
|
2001-03-06 22:42:12 +00:00
|
|
|
For Carbon MacPython you only get PIL: there is no Tcl/Tk for Carbon yet.
|
2001-10-31 10:13:52 +00:00
|
|
|
This is the reason Classic MacPython is also installed on MacOSX: it
|
|
|
|
allows you to run Tkinter applications, albeit in the Classic box.
|
2000-05-06 23:01:07 +00:00
|
|
|
- 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
|
2001-10-31 10:13:52 +00:00
|
|
|
on matrices and such. This is the most recent version from the
|
|
|
|
sourceforge archive.
|
|
|
|
Numeric has moved from Extensions to :Lib:site-python, by the way,
|
|
|
|
see the release notes.
|
|
|
|
- Developers kit: all header files and some tools and sample projects
|
|
|
|
to get you started on writing Python extensions if you have CodeWarrior.
|
2000-05-06 23:01:07 +00:00
|
|
|
All these except the DevKit are installed with Easy Install.
|
1997-08-26 13:25:06 +00:00
|
|
|
|
2001-03-06 22:42:12 +00:00
|
|
|
After the installer finishes it automatically launches the appropriate
|
2001-10-31 10:13:52 +00:00
|
|
|
ConfigurePython applet, to finish configuration of your Python. If you
|
|
|
|
run MacOS9 or later (or 8 with CarbonLib installed) you can switch
|
|
|
|
back and forth between the classic and Carbon versions of Python by
|
|
|
|
running either ConfigurePythonClassic or ConfigurePythonCarbon.
|
1997-08-26 13:25:06 +00:00
|
|
|
|
2001-10-31 10:13:52 +00:00
|
|
|
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. (there's a script zappyc.py that does the latter).
|
2000-11-14 20:37:37 +00:00
|
|
|
|
1997-08-26 13:25:06 +00:00
|
|
|
If you don't have enough memory: the sizes choosen are somewhat
|
2001-10-31 10:13:52 +00:00
|
|
|
arbitrary, and they are as high as they are so that test.autotest runs
|
|
|
|
with fewer problems. An average Python program can make do with much
|
|
|
|
less memory. Try lowering the application sizes in the finder "get
|
|
|
|
info" window, and seeing whether the resulting python is still usable.
|
1997-08-26 13:25:06 +00:00
|
|
|
|
|
|
|
After installing
|
|
|
|
----------------
|
|
|
|
|
2000-09-10 12:02:28 +00:00
|
|
|
It is probably a good idea to run the automatic tests. Start
|
2001-09-08 21:38:26 +00:00
|
|
|
Python and "import test.regrtest ; test.regrtest.main()".
|
2000-10-12 21:21:43 +00:00
|
|
|
|
2001-11-30 14:16:36 +00:00
|
|
|
test_frozen will fail in MacPython because of different handling on
|
|
|
|
frozen modules. This should not be a problem in normal use.
|
|
|
|
|
2001-09-08 21:38:26 +00:00
|
|
|
Three tests will fail on MacOS9 with MemoryErrors:
|
2001-10-23 22:22:09 +00:00
|
|
|
test_longexp, test_sha and test_zlib (on MacOSX these should pass).
|
2001-03-27 21:38:55 +00:00
|
|
|
|
2001-10-31 10:13:52 +00:00
|
|
|
If you increase the PythonInterpreter memory partition size they will
|
|
|
|
pass (but for longexp you have to increase it by an incredible amount,
|
|
|
|
400MB is rumoured). 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.

OSX Multiple users note
|
|
|
|
-----------------------
|
|
|
|
|
|
|
|
Interaction with Mac OS X multiple users has been tested only very lightly.
|
|
|
|
If you install as a privileged user everything installs fine.
|
|
|
|
|
|
|
|
If you install as a non-privileged user everything should install in your local
|
|
|
|
per-user folders. But: as there is no global PythonCore you can only run applets
|
|
|
|
if they reside in your toplevel Python folder.
|
|
|
|
|
|
|
|
If you install as a privileged user and then try to run
|
|
|
|
Python as another (non-privileged) user you may encounter a problem with
|
|
|
|
not having a preference file: the symptom is failing to import all sorts
|
|
|
|
of standard modules. If you remove your per-user Python preference files
|
|
|
|
(in ~/Library/Preferences) and then run PythonIntpreter once everything should
|
|
|
|
be fine.
|
|
|
|
|
1997-10-08 15:34:42 +00:00
|
|
|
Uninstalling
|
|
|
|
------------
|
|
|
|
|
2001-12-27 23:01:18 +00:00
|
|
|
Up to three items are installed in the system folder: the interpreter shared
|
|
|
|
libraries PythonCore and PythonCoreCarbon live in the Extensions
|
2002-04-23 19:50:53 +00:00
|
|
|
folder and the "Python 2.2.1 Preferences" file in the Python subfolder
|
2001-10-31 10:13:52 +00:00
|
|
|
in the Preferences folder. All the rest of Python lives in the folder
|
|
|
|
you installed in.
|
|
|
|
|
2001-12-27 23:01:18 +00:00
|
|
|
On OSX the libraries are installed in /Library/CFMSupport. The ConfigurePython
|
|
|
|
applets will complain if you have no right to create the libraries there
|
|
|
|
(you need Admin privileges). This has one consequence: you will not be able to
|
|
|
|
run applets unless they reside in the MacPython folder (such as the IDE or
|
|
|
|
EditPythonPrefs). If you try to run an applet stored elsewhere you will
|
|
|
|
get a "Cannot locate PythonCore" error message.

Things to see
|
|
|
|
-------------
|
|
|
|
|
2000-05-06 23:01:07 +00:00
|
|
|
Start off at Mac:Demo:index.html. Read at least the first few sections.
|
|
|
|
|
2000-09-10 12:02:28 +00:00
|
|
|
There are also some interesting files in the "Relnotes" folder that may
|
1997-08-26 13:25:06 +00:00
|
|
|
contain useful information. There is also a first stab at documentation
|
|
|
|
(plus examples) in the Mac:Demo folder. The toplevel Demo folder has
|
2000-05-06 23:01:07 +00:00
|
|
|
machine-independent demos.
|
|
|
|
The Mac:Lib:test folder also has some programs that show simple
|
1997-08-26 13:25:06 +00:00
|
|
|
capabilities of various modules.
|
|
|
|
|
2001-10-31 10:13:52 +00:00
|
|
|
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.
|
1997-08-26 13:25:06 +00:00
|
|
|
|
2001-10-31 10:13:52 +00:00
|
|
|
Other mac-specific goodies can be found in :Mac:Tools, of which the
|
|
|
|
IDE sources and a CGI framework deserve special mention.
|
2000-09-10 12:02:28 +00:00
|
|
|
|
1997-08-26 13:25:06 +00:00
|
|
|
The 'img' group of modules, which handles I/O of many different image
|
1998-04-27 15:14:36 +00:00
|
|
|
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
|
2000-05-06 23:01:07 +00:00
|
|
|
software.
|
1997-08-26 13:25:06 +00:00
|
|

|
|
|
Upgrading from older Python releases
|
|
|
|
------------------------------------
|
|
|
|
|
2001-10-31 10:13:52 +00:00
|
|
|
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
|
1997-08-26 13:25:06 +00:00
|
|
|
whether to upgrade. The bad news is that your old preference settings
|
|
|
|
are lost and you have to set them again.
|
|
|
|
|
2002-04-23 19:50:53 +00:00
|
|
|
After you are satisfied that 2.2.1 works as expected you can trash
|
1997-08-26 13:25:06 +00:00
|
|
|
anything in the system folder that has "python" in the name and not
|
2002-04-23 19:50:53 +00:00
|
|
|
"2.2.1".
|
1997-08-26 13:25:06 +00:00
|
|
|
|
2001-10-31 10:13:52 +00:00
|
|
|
The ConfigurePython... applets will try to detect incompatible
|
|
|
|
preferences files and offer to remove them. This means that re-running
|
|
|
|
ConfigurePython after a second install of the same MacPython version
|
|
|
|
(or after moving the Python folder) should fix things up correctly.

the brilliant unix-compatible GUSI I/O library, without which

MacPython would not have sockets or select, and to Alexandre
