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.
