PythonMBS.ExecPrefix as String

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared property	Python	MBS Python Plugin	24.3	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Return the exec-prefix for installed platform-dependent files.

This is derived through a number of complicated rules from the program name set with Py_SetProgramName() and some environment variables; for example, if the program name is '/usr/local/bin/python', the exec-prefix is '/usr/local'.
The value is available to Python code as sys.exec_prefix. It is only useful on Unix.

Background: The exec-prefix differs from the prefix when platform dependent files (such as executables and shared libraries) are installed in a different directory tree. In a typical installation, platform dependent files may be installed in the /usr/local/plat subtree while platform independent may be installed in /usr/local.

Generally speaking, a platform is a combination of hardware and software families, e.g. Sparc machines running the Solaris 2.x operating system are considered the same platform, but Intel machines running Solaris 2.x are another platform, and Intel machines running Linux are yet another platform. Different major revisions of the same operating system generally also form different platforms. Non-Unix operating systems are a different story; the installation strategies on those systems are so different that the prefix and exec-prefix are meaningless, and set to the empty string. Note that compiled Python bytecode files are platform independent (but not independent from the Python version by which they were compiled!).

System administrators will know how to configure the mount or automount programs to share /usr/local between platforms while having /usr/local/plat be a different filesystem for each platform.

PythonMBS.LibraryError as String

PythonMBS.LibraryVersion as String

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared property	Python	MBS Python Plugin	24.3	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Queries the version text of the Python library.

Returns e.g. "3.12.3 (main, Apr 9 2024, 08:09:14) [Clang 15.0.0 (clang-1500.3.9.4)]"

PythonMBS.Loaded as Boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared property	Python	MBS Python Plugin	24.3	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Queries whether Python libraries have been loaded.

Returns true if loaded or false if not.

PythonMBS.Path as String

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared property	Python	MBS Python Plugin	24.3	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Return the default module search path.

This is computed from the program name (set by assigning ProgramName) and some environment variables. The returned string consists of a series of directory names separated by a platform dependent delimiter character. The delimiter character is ':' on Unix and macOS, ';' on Windows.
The list sys.path is initialized with this value on interpreter startup; it can be (and usually is) modified later to change the search path for loading modules.

e.g.
/opt/homebrew/Cellar/python@3.12/3.12.3/Frameworks/Python.framework/Versions/3.12/lib/python312.zip:/opt/homebrew/Cellar/python@3.12/3.12.3/Frameworks/Python.framework/Versions/3.12/lib/python3.12:/opt/homebrew/Cellar/python@3.12/3.12.3/Frameworks/Python.framework/Versions/3.12/lib/python3.12/lib-dynload

PythonMBS.Prefix as String

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets

Return the prefix for installed platform-independent files.

This is derived through a number of complicated rules from the program name set with Py_SetProgramName() and some environment variables; for example, if the program name is '/usr/local/bin/python', the prefix is '/usr/local'.

PythonMBS.ProgramFullPath as String

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared property	Python	MBS Python Plugin	24.3	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Return the full program name of the Python executable

This is computed as a side-effect of deriving the default module search path from the program name (set by assignment to ProgramName).
The value is available to Python code as sys.executable.
This is usually the path to your Xojo application.

PythonMBS.ProgramName as String

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared property	Python	MBS Python Plugin	24.3	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

The program name.

Can be set before initializing Python, otherwise the default will be "python".
(Read and Write property)

PythonMBS.PythonHome as String

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
shared property	Python	MBS Python Plugin	24.3	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

The default "home" path.

The value is set by a previous with setting PythonHome property, or the value is the value of the PYTHONHOME environment variable if it is set.
