PYTHON RELEASE NOTES FOR THE MACINTOSH
|
||||||
|
|
||||||
|
VERSION 1.0.2
|
||||||
|
|
||||||
|
For the most part, Python on the Mac works just like Python under UNIX.
|
||||||
|
The most important differences are:
|
||||||
|
|
||||||
|
- Since there is no shell environment on the Mac, the start-up file
|
||||||
|
has a fixed name: PythonStartup. If a file by this name exists
|
||||||
|
(either in the current folder or in the system folder) it is executed
|
||||||
|
when an interactive interpreter is started.
|
||||||
|
|
||||||
|
- The default search path for modules is different: first the current
|
||||||
|
directory is searched, then the subdirectories 'lib', 'lib:stdwin' and
|
||||||
|
'demo'. As always, you can change this (e.g. in your PythonStartup
|
||||||
|
file) by assigning or appending to sys.path -- use Macintosh pathnames!
|
||||||
|
(The default contains no absolute paths because these are unlikely
|
||||||
|
to make sense on other people's hard disks.)
|
||||||
|
|
||||||
|
- The user interface for typing interactive commands is different.
|
||||||
|
This is actually the THINK C console I/O module, which is based on
|
||||||
|
the Mac toolbox TextEdit. A standard Edit menu provides Cut, Copy,
|
||||||
|
Paste and Clear (Undo is only there for Desk Accessories). A minimal
|
||||||
|
File menu provides Quit, which immediately exits the application,
|
||||||
|
without the usual cleanup. You can Copy from previous output,
|
||||||
|
but you can't scroll back beyond the 24x80 screen. The TAB key
|
||||||
|
always brings you to the end of the current input line; indentation
|
||||||
|
must be entered with spaces (a single space is enough).
|
||||||
|
End-of-file is generated by Command-D; Command-Period interrupts.
|
||||||
|
There is an annoying limit in the length of an input line to a single
|
||||||
|
screen line (less the prompt). Use \ to input long statements.
|
||||||
|
Change your program if it requires long lines typed on input.
|
||||||
|
Even though there is no resize box, the window can be resized by
|
||||||
|
dragging its bottom right corner, but the maximum size is 24x80.
|
||||||
|
|
||||||
|
- Tabs in module files are interpreted as 4 (four!) spaces. This is
|
||||||
|
consistent with most Mac editors that I know. For individual files
|
||||||
|
you can change the tab size with a comment like
|
||||||
|
|
||||||
|
# vi:set tabsize=8:
|
||||||
|
|
||||||
|
(exactly as shown here, including the colons!). If you are consistent
|
||||||
|
in always using tabs for indentation on UNIX, your files will be
|
||||||
|
parsed correctly on the Mac, although they may look funny if you
|
||||||
|
have nicely lined-up comments or tables using tabs. Never using tabs
|
||||||
|
also works. Mixing tabs and spaces to simulate 4-character indentation
|
||||||
|
levels is likely to fail.
|
||||||
|
|
||||||
|
- You can start a script from the Finder by selecting the script and
|
||||||
|
the Python interpreter together and then double clicking. If you
|
||||||
|
make the owner of the script PYTH (the type should always be TEXT)
|
||||||
|
Python will be launched if you double click it!
|
||||||
|
There is no way to pass command line arguments to Python scripts.
|
||||||
|
|
||||||
|
- The set of built-in modules is different:
|
||||||
|
|
||||||
|
= Operating system functions for the 'os' module is provided by the
|
||||||
|
built-in module 'mac', not 'posix'. This doesn't have all the
|
||||||
|
functions from posix, for obvious reasons (if you know the Mac
|
||||||
|
O/S a little bit). The functions in os.path are provided by
|
||||||
|
macpath, they know about Mac pathnames etc.
|
||||||
|
|
||||||
|
= None of the UNIX specific modules ('socket', 'pwd', 'grp' etc.)
|
||||||
|
exists.
|
||||||
|
|
||||||
|
= Module 'stdwin' is always available. It uses the Mac version of
|
||||||
|
STDWIN, which interfaces directly with the Mac toolbox. The most
|
||||||
|
important difference is in the font names; setfont() has a second
|
||||||
|
argument specifying the point size and an optional third one
|
||||||
|
specifying the variation: a single letter character string,
|
||||||
|
'i' for italics, 'b' for bold. Note that when STDWIN is waiting
|
||||||
|
for events, the standard File and Edit menus are inactive but
|
||||||
|
still visible, and (most annoyingly) the Apple menu is also inactive;
|
||||||
|
conversely, menus put up by STDWIN are not active when the Python is
|
||||||
|
reading from the keyboard. If you open Python together with a text
|
||||||
|
file containing a Python script, the script will be executed and
|
||||||
|
a console window is only generated when the script uses standard
|
||||||
|
input or output. A script that uses STDWIN exclusively for its I/O
|
||||||
|
will have a working Apple menu and no extraneous File/Edit menus.
|
||||||
|
(This is because both stdwin and stdio try to initialize the
|
||||||
|
windowing environment; whoever gets there first owns the Apple menu.)
|
||||||
|
LIMITATIONS: a few recent additions to STDWIN for X11 have not yet
|
||||||
|
been added to the Mac version. There are no bitmap objects, and
|
||||||
|
the setwinpos() and setwinsize() methods are non--functional.
|
||||||
|
|
||||||
|
- Because launching an application on the Mac is so tedious, you will
|
||||||
|
want to edit your program with a desk accessory editor (e.g., Sigma
|
||||||
|
edit) and test the changed version without leaving Python. This is
|
||||||
|
possible but requires some care. Make sure the program is a module
|
||||||
|
file (filename must be a Python identifier followed by '.py'). You
|
||||||
|
can then import it when you test it for the first time. There are
|
||||||
|
now three possibilities: it contains a syntax error; it gets a runtime
|
||||||
|
error (unhandled exception); or it runs OK but gives wrong results.
|
||||||
|
(If it gives correct results, you are done testing and don't need
|
||||||
|
to read the rest of this paragraph. :-) Note that the following
|
||||||
|
is not Mac-specific -- it's just that on UNIX it's easier to restart
|
||||||
|
the entire script so it's rarely useful.
|
||||||
|
|
||||||
|
Recovery from a syntax error is easy: edit the file and import it
|
||||||
|
again.
|
||||||
|
|
||||||
|
Recovery from wrong output is almost as easy: edit the file and,
|
||||||
|
instead of importing it, call the function reload() with the module
|
||||||
|
name as argument (e.g., if your module is called foo, type
|
||||||
|
"reload(foo)").
|
||||||
|
|
||||||
|
Recovery from an exception is trickier. Once the syntax is correct,
|
||||||
|
a 'module' entry is placed in an internal table, and following import
|
||||||
|
statements will not re-read the file, even if the module's initialization
|
||||||
|
terminated with an error (one reason why this is done is so that
|
||||||
|
mutually recursive modules are initialized only once). You must
|
||||||
|
therefore force re-reading the module with reload(), however, if this
|
||||||
|
happens the first time you try to import the module, the import statement
|
||||||
|
itself has not completed, and your workspace does not know the module
|
||||||
|
name (even though the internal table of moduesl does!). The trick is
|
||||||
|
to first import the module again, then reload it. For instance,
|
||||||
|
"import foo; reload(foo)". Because the module object already exists
|
||||||
|
internally, the import statement does not attempt to execute the
|
||||||
|
module again -- it just places it in your workspace.
|
||||||
|
|
||||||
|
When you edit a module you don't have to worry about the corresponding
|
||||||
|
'.pyc' file (a "compiled" version of the module, which loads much faster
|
||||||
|
than the textual version): the interpreter notices that the '.py' file
|
||||||
|
has changed (because its modification time has changed) and ignores the
|
||||||
|
'.pyc' file. When parsing is successful, a new '.pyc' file is written;
|
||||||
|
if this fails (no write permission, disk full or whatever) it is
|
||||||
|
silently skipped but attempted again the next time the same module
|
||||||
|
is loaded. (Thus, if you plan to place a Python library on a read-only
|
||||||
|
disk, it is advisable to "warm the cache" by making the disk writable
|
||||||
|
and importing all modules once. The standard module 'importall' helps
|
||||||
|
in doing this.)
