[RFC] Summer of code project to re-think plug-in/filter development resources

[CmykStudent]

MrsP-from-C: Hi! This should be fixed, so can you point to a function you tested that gave the wrong code output? For instance, gimp-edit-named-copy outputs "config.set_core_object_array('drawables', [drawable])" in the Python console.

That was
script-fu-selection-rounded-rectangle

just yesterday. Thanks for looking into it.

As you are there: could you also look into that output and make it use lines instead of chaining it all in one line?
That would be much easier to handle.

I just tried with version 3.0.4 and script-fu-selection-rounded-rectangle gives me the right way to set the drawable.

That said, could we, please, stay on topic? For reporting bugs, please, use the bug tracker. And I already opened a ticket regarding both the long lines and that the provided code uses exclusively PDB procedures instead of libgimp wrappers for them. See https://gitlab.gnome.org/GNOME/gimp/-/issues/14266.

This is what I get using the official 3.0.4 appimage:

I confirm, had the same problem recently. when I used that to create a call in the Python console.

Otherwise, I'm using this in my code:

Code:

def callProcedure(procId: str, run_mode=Gimp.RunMode.NONINTERACTIVE, **kwargs):
    procedure=Gimp.get_pdb().lookup_procedure(procId)
    if procedure is None:
        raise Exception(f'Procedure "{procId}" no found')
    config: Gimp.ProcedureConfig = procedure.create_config()
    #configuration.set_property('run-mode',run_mode)
    for name,value in kwargs.items():
        if isinstance(value,list):
            config.set_core_object_array(name.replace('_','-'),value)
        else:
            config.set_property(name.replace('_','-'),value)
    result=procedure.run(config)
    results = [result.index(i) for i in range(result.length())]
    if results[0] is not Gimp.PDBStatusType.SUCCESS:
        raise Exception(f'Error returned from procedure "{procId}": {results[0].value_name}')
    return results[1:]

This infers the config data from keyword arguments (python_style_names being replaced by equivalent config-element-names), and handles the set_property/set_core_object_array automatically.

Used like this:

Code:

# Other args of sel2path are default values
    res = callProcedure('plug-in-sel2path', image=scaledImage, drawables=[layer])

Thank you, Ofnuts.
I'll give that a try.

But honestly: this could be done right in GIMP from the start.
