- How to install Python 1.3.3 on your Macintosh
- ------------------------------------------------
-
- Even if you don't usually read readme files: please read at least the
- first sections of this file, failure to do so will probably result in
- an unuseable python system. If this warning is too late and you already
- have an non-functional python: it is best to remove all traces and start
- with a fresh distribution. Especially don't forget to remove the
- "python preferences" file from the Preferences folder, and possibly
- "PythonCore" from the Extensions folder. Before you mail me for help *please*
- try the steps above (cleaning up and re-installing): it should fix most
- common mistakes.
-
- 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.
-
- 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.
-
- 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 really want one: tell me, maybe I can be convinced.
- Alternatively: get the sources, put in the necessary gestalt() and
- compatability calls yourself and send me the results.
-
- If you don't have enough memory: the sizes choosen are somewhat arbitrary.
- Try lowering them and seeing whether the resulting python is still usable.
- Note, however, that python running out of memory may result in your mac
- freezing. If this happens I would like to hear of it.
-
- Note that if you're using Tk you might want to raise the memory size, tcl
- and tk are quite a memory hog.
-
- PowerPC Macintosh instructions
- ------------------------------
-
- 1. Remove older versions of "PythonCore" and "Python Preferences"
- from your system folder.
-
- 2. Run the MkPluginAliases applet. This will first ask you whether it should
- create an initial preferences file. Let it do so. Next, it will create a
- number of aliases in the PlugIns folder. If this fails in mysterious ways
- examine the script (in Mac:scripts:MkPluginAliases.py) and create the aliases
- by hand (and tell me what you did to make the script fail:-).
-
- 3. To make sure any applets you create can find the common interpreter code
- you should move PythonCore to the Extensions folder (drop it on the
- System Folder and it will find its own way). Alternatively, you can
- make an alias called "PythonCore" in the Extensions folder and
- point it to the real PythonCore. You may want to start PythonPPC
- again at this point to check that you actually put the extension in
- the right place.
-
- 4. You're all set now. Continue with the common instructions.
-
- 68K Macintosh instructions
- --------------------------
-
- 1. Remove old "Python Preferences" file from the Preferences folder, if you
- have one (the file, that is, not the folder:-).
-
- 2. Run Python68K. This will create an initial preferences file (after
- asking you if that's ok with you). Quit python.
-
- 3. Continue with the next section.
-
- Common instructions
- -------------------
-
- You should now have a functioning python. It is probably a good idea to run
- "testall.py" from :Lib:test at this point, this should not give any errors.
- Running testall.py is done by double-clicking it or dropping it onto the
- interpreter.
- Next, try "compileall.py" from :Lib to create all .pyc files (but this isn't
- really important).
-
- PPC 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 "liberal", you can remove stdwin and tkinter if
- you don't use them and maybe others.
- - RunLibScript allows you to run any script as __main__ after setting arguments,
- changing stdin/stdout/workdir, etc. Most of this functionality can also be
- obtained nowadays by option-dragging a script to the interpreter.
- - For PPC only, 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.
-
- PPC users will see one more files in the python folder: PythonApplet. This is
- the template for building applets, leave it alone.
-
- 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
- (not pict yet, sigh:-) is included, but without documentation. You can find
- docs at ftp://ftp.cwi.nl/pub/jack/python/img (or somewhere around there).
-
- Feedback
- --------
-
- Send bug reports, suggestions, contributions and fanmail to <jack@cwi.nl>.
- Be warned however that I'm pretty busy at the moment, so I may not always
- respond immedeately.
- 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:-).
