- How to install Python 1.5.2 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
- -------
- There are still problems with cfm68k Python. 68K Mac users should
- probably try to use the cfm68k distribution first, and revert to the
- classic 68k distribution in case the bugs make their Python
- unworkable. The main problem is that packages ("dotted import") and
- NumPy printing don't work.
-
- What to install
- ---------------
-
- There are three flavors of Python: PowerPC, cfm68k and Classic 68k
- (the FAT flavor is just a combination of the first two, which is handy
- if you want to install Python on a fileserver or so). 68K-mac owners
- should definitely use the cfm68k version if possible, since it enables
- the use of applets and dynamically loaded modules and usually has a
- smaller memory footprint. If you have an older system than MacOS 8 it
- does however need the CFM68K Runtime Enabler which is available from
- Apple (available for free from
- <http://support.info.apple.com/ftp/swhome.html>, included since MacOS
- 7.6.1 and builtin to the system since MacOS 8). If your machine is
- pre-68020 you cannot use cfm68k and you can install the classic 68k
- Python.
-
- After the installer finishes it automatically launches the
- ConfigurePython applet, to finish configuration of your Python
- installation (except for classic 68K installations, where no extra
- configuration is needed).
-
- If you have a pre-system 7 macintosh: sorry, this release will not work
- on your system. Too many sys7 features are used to make a sys6 python
- easy to create.
-
- 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.
-
- A final note to CFM68K (and possibly PPC) users: the Code Fragment
- Manager can (incorrectly) produce "library not found" and other strange
- error messages when it really means that there is not enough room in the
- system heap. Decreasing (yes, *de*creasing) the size of the interpreter
- and/or enabling virtual memory may solve these problems.
-
- After installing
- ----------------
-
- The first step thing you could try is to run "compileall.py" to create
- all .pyc files, but this isn't very important, as pyc files are
- created on-the-fly as well. You may also want to skip this step if you
- are low on diskspace.
-
- Next, it is probably a good idea to run the automatic tests. Start
- Python and "import test.autotest". This should not print any
- errors. 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.
-
- PPC and CFM68K users have a couple of applets in the main folder they
- may want to try, (68K users can use the corresponding scripts from the
- "scripts" folder):
-
- - EditPythonPrefs allows you to edit the preferences file, to change the
- python home folder or modify the initial sys.path setting. The default
- settings are somewhat arbitrary, you can remove tkinter if you don't use
- it and possibly add Extensions:img:Lib. - mkapplet creates a python
- applet, a tiny application written in python. Drop a python source on it
- and out comes the application. More information can be found in the
- "Mac:Demo" folder.
-
- If you have a slow machine you may want to disable automatic site.py import
- since site.py does not do too much on the mac (unless you make it do
- something), and it can take a few seconds.
-
- PPC and CFM68K users will see one more file in the python folder:
- PythonApplet. This is the template for building applets, leave it alone.
- The applet is "fat", containing both PPC and CFM68K code. Hence, applets
- built with it can be transported to machines with the other
- architecture.
-
- Uninstalling
- ------------
-
- Two items are installed in the system folder: the interpreter shared
- library "PythonCore 1.5.2b1" lives in the Extensions folder and the
- "Python 1.5.2b1 Preferences" file in the Preferences folder. All the rest
- of Python lives in the folder you installed in.
-
- Things to see
- -------------
-
- There are some readme files in the "Read me files" 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. See the file Readme-mac for mac-specific
- notes. The Mac:Lib:test folder also has some programs that show simple
- capabilities of various modules.
-
- The "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.
-
- 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, including a Real Programming Environment and some AppleScript
- related modules.
-
- 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 1.5.2b1 works as expected you can trash
- anything in the system folder that has "python" in the name and not
- "1.5.2b1".
-
- The installer
- -------------
-
- The installer for this product was created using Installer VISE Lite
- from MindVision Software. For more information on Installer VISE Lite,

-
- Just van Rossum <just@letterror.nl> created the installer.
-
- 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:-).
