- Changes since 1.3beta3
- ----------------------
- - MkPluginAliases.py now works in a virgin distribution environment. It is
- also distributed as an applet.
- - hexbin from binhex.py has been fixed
- - various bits and pieces in readme files clarified
- - mkapplet bug wrt owner resource (and, hence, trouble starting applets) fixed.
- - Compiled with CodeWarrior 7.
- - AE client modules generated with gensuitemodule.py now use keyword args.
- - img modules updated to latest version (including pbm and sgi support).
- - Everything compiled with all optimization options available. Let me know
- if you suspect errors that are due to this.
-
- Changes since Python 1.2 for the mac
- ------------------------------------
- - PPC python now uses a shared library organization. This allows the
- creation of dynamically loadable extension modules (contact me) and
- creation of python applets (see mkapplet.py). A number of previously
- builtin modules are now dynamically loaded. Dynamically loaded
- modules are distributed in the PlugIns folder.
- - Python modules can live in 'PYC ' resources (with a name equal to the
- module name, so many modules can live in a single file). If you put a
- file (in stead of a folder) in sys.path its resources will be searched.
- See the PackLibDir script for creating such a file.
- - new binhex module (partially working, hexbin has problems)
- - Python now has a Preferences file, editable with
- EditPythonPrefs. Remembered are the python 'home folder' and the
- initial value for sys.path. If no preferences file is found a simple
- one is created.
- NOTE: this only works correctly if you start python the first time
- from the correct folder.
- - new img modules, to read/write/convert images in various formats
- - new MacOS toolbox modules: AE, Ctl, Dlg, Event, List, Qd, Res, Snd
- and Win. These provide access to various of the MacOS toolbox
- interfaces. No documentation yet, but the __doc__ strings provide at
- least the calling sequence (and Inside Mac will give you the
- semantics). Minimal demos are provided for most toolbox interfaces,
- and the 'scripts' directory has some more examples.
- - AppleEvent client interfaces can be generated from aete/aeut
- resources. No support for objects yet, nor for server interfaces.
- - Lib:mac:FrameWork.py has an application framework (under
- construction).
- - (PPC Only) support for building Python applets: tiny standalone
- python applications.
- - fp = open(filename, '*r') opens resource-fork of a file for reading
- (and similar for writing).
- - option-dragging a file to the interpreter (or immedeately pressing
- <option> after launching python) will bring up an Options dialog
- allowing you to set options like import-tracing, etc.
- - MacOS module method added: GetErrorString(OSErr) -> error string
- - There is now a numbering convention for resource-ID's:
- 128-255 Resources used by the interpreter itself
- 256-511 Resources used by standard modules
- 512- Resources for applications
- - macfs module changes:
- - StandardGetFile without type arguments now shows all files
- - PromptGetFile(prompt, ...) is like StandardGetFile but with a
- prompt
- - GetDirectory (let user select a folder) added
- - GetFInfo and SetFInfo methods of FSSpec objects get/set finder
- info. FInfo objects have attributes Creator, Type, etc.
- - FindFolder (locate trash/preferences/etc) added
- - mactcp/macdnr changes: bug fix wrt idle-loop.
- - EditPythonPrefs script: change initial sys.path and python home
- folder
- - (PPC only) MkPluginAliases: Setup aliases for dynamically loadable
- modules that live in a single shared library
- - PackLibDir: Convert Lib directory to a single resource file
- containing all .pyc code
- - fixfiletypes: Set file types based on file extension over a whole
- tree.
- - RunLibScript: Run any script as main program, optionally redirecting
- stdin/stdout, supplying arguments, etc.
- - binhextree: Binhex all files in a tree, depending on the extension.
- - (PPC only) mkapplet: Create a python applet from a sourcefile and
- (optional) resourcefile.
-
- Known problems
- --------------
-
- - 68K python reacts rather violently to out-of-memory situations. In
- stead of raising MemoryError it will crash, possibly bringing down the
- whole system. This is being investigated.
- - The installation procedure is baroque. Ideas for improvement are welcome.
- - The full documentation should be ported to AppleGuide. This should be
- a fairly simple automatic translation but I am not well-versed enough in
- AppleGuide to do it. Any takers?
- - stdwin still has trouble with getting the clipboard (for cut/copy). Any
- hints for fixing this will be looked into (but I am not going to spend
- ages on this, especially without anyone asking me to).
- - Be careful when copy/pasting in the stdin/stdout window. If you type
- something when you have the insertion point is not at end-of-window you
- may experience a system hang. (thanks, Just!)

-
- What will change shortly
- ------------------------
-
- I am planning to do an intermediate release shortly (1.3.1??), mainly
- because Guido was so fast with 1.3 that I didn't have time to do some
- things I wanted. Expect the following changes shortly (note that some are
- incompatible):
- - CFM68K support,bringing applets and dynamic loading to the 68K macs.
- - Bgen-generated toolbox interfaces will go to a different place,
- probably :Lib:mac:toolbox
- - Resource objects now often perform the role of a Handle object. This
- will change with the introduction of a Handle object and some sort of
- simulated inheritance.
- - AE suites generated with gensuitemodule will be restructured, whereby it
- will be easier to override/extend standard suites. Also, server suites
- will also be generated, and hopefully objects will be supported.
- - Event handling is currently rather messy, with python, SIOUX, stdwin and
- the python application all fighting over the events. This will somehow
- be changed.
