class rez.utils.execution.ExecutableScriptMode

Which scripts to create with util.create_executable_script.

rez.utils.execution.create_executable_script(filepath, body, program=None, py_script_mode=None)

Create an executable script. In case a py_script_mode has been set to create a .py script the shell is expected to have the PATHEXT environment variable to include “.PY” in order to properly launch the command without the .py extension.

Parameters:

• filepath (str) – File to create.

• body (str or callable) – Contents of the script. If a callable, its code is used as the script body.

• program (str) – Name of program to launch the script. Default is ‘python’

• py_script_mode (ExecutableScriptMode) – What kind of script to create. Defaults to rezconfig.create_executable_script_mode.

Returns:

List of filepaths of created scripts. This may differ from the supplied filepath depending on the py_script_mode

rez.utils.execution.create_forwarding_script(filepath, module, func_name, *nargs, **kwargs)

Create a ‘forwarding’ script.

A forwarding script is one that executes some arbitrary Rez function. This is used internally by Rez to dynamically create a script that uses Rez, even though the parent environment may not be configured to do so.
