Detailed Description

Common Arguments

C the bContext (never NULL).
imports: This is simply supported for convenience since imports can make constructing strings more cumbersome as otherwise small expressions become multi-line code-blocks. Optional (ignored when NULL), otherwise this is a NULL terminated array of module names.

Failure to import any modules prevents any further execution.
err_info BPy_RunErrInfo is passed to some functions so errors can be forwarded to the UI. Option (when NULL errors are printed to the stdout and cleared). However this should be used in any case the error would be useful to show to the user.

Function Documentation

◆ BPY_run_filepath()

bool BPY_run_filepath	(	bContext *	C,
		const char *	filepath,
		ReportList *	reports )

Execute filepath as a Python script.

Wrapper for PyRun_File (similar to calling python with a script argument). Used for the --Python command line argument.

Parameters

C	The context (never NULL).
filepath	The file path to execute.
reports	Failure to execute the script will report the exception here (may be NULL).

Returns: true on success, otherwise false with an error reported to reports.

Note: Python scripts could consider bpy.utils.execfile, which has the advantage of returning the object as a module for data access & caching pyc file for faster re-execution.

◆ BPY_run_string_eval()

bool BPY_run_string_eval	(	bContext *	C,
		const char *	imports[],
		const char *	expr )

Run an expression, matches: exec(compile(..., "eval")).

Parameters

C	Optional context (may be null), used for bpy.context and reporting errors to CTX_wm_reports(C).

◆ BPY_run_string_exec()

bool BPY_run_string_exec	(	bContext *	C,
		const char *	imports[],
		const char *	expr )

Run an entire script, matches: exec(compile(..., "exec"))

◆ BPY_run_text()

bool bool BPY_run_text	(	bContext *	C,
		Text *	text,
		ReportList *	reports,
		bool	do_jump )

Execute a Blender text block as a Python script.

Wrapper for Py_CompileStringObject & PyEval_EvalCode. Used for the --python-text command line argument.

Parameters

C	The context (never NULL).
text	The text-block to execute.
reports	Failure to execute the script will report the exception here (may be NULL).
do_jump	When true, any error moves the cursor to the location of that error. Useful for executing scripts interactively from the text editor.

Returns: true on success, otherwise false with an error reported to reports.

Note: The __file__ is constructed by joining the blend file-path to the name of the text. This is done so error messages give useful output however there are rare cases causes problems with introspection tools which attempt to load __file__.
