Scripting

[aalex]

Would it be interested to integrate Lua or Python scripting into MapMap?

Yes...I will do dirty nasty things.

Check out BlenderSync to see an example of what I did with Blender's python API.

Blender has an amazing simple system in which there is a global varible that contains a dictionnary (in C++, a map) of all the objects. So, we could have the same in MapMap.

For example: (in Python)

world["mapping"]["example_0"].position = (0.432, 0.123)

AO-StreetArt: you prefer Python? (disclaimer: I do too) Other options: JavaScript, R, Lua.

Alex, I would very much prefer Python, as I am an active Python developer :)

I already did implement some Python scripting in a C++ system. It should not be too difficult.

cling based C++ as scripting language / hot code reload Why? Able to run C++ script in runtime or compile it for max speed ( as in example https://github.com/derofim/cling-cmake ) Also: May be used to improve modules compile time

HOT code reload possible approaches:

store app state fix cling undo for files https://root-forum.cern.ch/t/loading-unloading-class-as-interpreted-macro-in-cling-multiple-times/32976/2

execute cling code to change callbacks & variables nested cling::Interpreter with multiple cling::MetaProcessor IDK how to do it, but you can create child cling::Interpreter
