\modulesynopsis{Access to Mac OS-specific interpreter features.}
|
|
|
|
|
|
This module provides access to MacOS specific functionality in the
|
|
Python interpreter, such as how the interpreter eventloop functions
|
|
and the like. Use with care.
|
|
|
|
Note the capitalization of the module name; this is a historical
|
|
artifact.
|
|
|
|
\begin{datadesc}{runtimemodel}
|
|
Always \code{'macho'}, from Python 2.4 on.
|
|
In earlier versions of Python the value could
|
|
also be \code{'ppc'} for the classic Mac OS 8 runtime model or
|
|
\code{'carbon'} for the Mac OS 9 runtime model.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{linkmodel}
|
|
The way the interpreter has been linked. As extension modules may be
|
|
incompatible between linking models, packages could use this information to give
|
|
more decent error messages. The value is one of \code{'static'} for a
|
|
statically linked Python, \code{'framework'} for Python in a Mac OS X framework,
|
|
\code{'shared'} for Python in a standard \UNIX{} shared library.
|
|
Older Pythons could also have the value
|
|
\code{'cfm'} for Mac OS 9-compatible Python.
|
|
\end{datadesc}
|
|
|
|
\begin{excdesc}{Error}
|
|
This exception is raised on MacOS generated errors, either from
|
|
functions in this module or from other mac-specific modules like the
|
|
toolbox interfaces. The arguments are the integer error code (the
|
|
\cdata{OSErr} value) and a textual description of the error code.
|
|
Symbolic names for all known error codes are defined in the standard
|
|
module \refmodule{macerrors}.\refstmodindex{macerrors}
|
|
\end{excdesc}
|
|
|
|
|
|
\begin{funcdesc}{GetErrorString}{errno}
|
|
Return the textual description of MacOS error code \var{errno}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{DebugStr}{message \optional{, object}}
|
|
On Mac OS X the string is simply printed to stderr (on older
|
|
Mac OS systems more elaborate functionality was available),
|
|
but it provides a convenient location to attach a breakpoint
|
|
in a low-level debugger like \program{gdb}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{SysBeep}{}
|
|
Ring the bell.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{GetTicks}{}
|
|
Get the number of clock ticks (1/60th of a second) since system boot.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{GetCreatorAndType}{file}
|
|
Return the file creator and file type as two four-character strings.
|
|
The \var{file} parameter can be a pathname or an \code{FSSpec} or
|
|
\code{FSRef} object.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{SetCreatorAndType}{file, creator, type}
|
|
Set the file creator and file type.
|
|
The \var{file} parameter can be a pathname or an \code{FSSpec} or
|
|
\code{FSRef} object. \var{creator} and \var{type} must be four character
|
|
strings.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{openrf}{name \optional{, mode}}
|
|
Open the resource fork of a file. Arguments are the same as for the
|
|
built-in function \function{open()}. The object returned has file-like
|
|
semantics, but it is not a Python file object, so there may be subtle
|
|
differences.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{WMAvailable}{}
|
|
Checks whether the current process has access to the window manager.
|
|
The method will return \code{False} if the window manager is not available,
|
|
for instance when running on Mac OS X Server or when logged in via ssh,
|
|
or when the current interpreter is not running from a fullblown application
|
|
bundle. A script runs from an application bundle either when it has been
|
|
started with \program{pythonw} instead of \program{python} or when running
|
|
as an applet.
|
|
\end{funcdesc}
