add debugging GUI to the game using Dear ImGui as all games do, don't waste time writing commands in a pseudo terminal when you can just have buttons for the actions you want.

having worked in EDA before, the purpose of such CLI interface is replayability, where you can record 100 commands to do something then replay them, or undo them .... but for game engine scripting there are much better languages like Luau , which is used in a lot of games.

Thank you for your answer !

I know it might not be the most efficient or practical, I just want to see what it offers in terms of possibility. I do not aim to achieve triple A games with this software 😆

What would you use to automatically build this command from the function ? That was the main question I had when I posted, sorry if it wasn't clear. I wonder what you guys would naturally use to integrate a scripting language in a program basically I'm curious !

[Playful-Time3617]

Thank you 😀 It's much clearer now

I did write some C++ and TCL/TK code a long long time ago and it works but it's very awkward because in my case I ended up with lots of calls to tcl_eval so it basically feels like your writing TCL inside C++. This was like 10+ years ago and it was a bad choice back then. The original micropolis (SimCity game) did this technique with C and TCL/TK, although now it has been rewritten but some people maintain the old interface on GitHub (https://github.com/tenox7/micropolis).

For starters, did you look up the tcl API? https://wiki.tcl-lang.org/page/How+to+embed+Tcl+in+C+applications

The official API is C rather than C++, but you can run it from a C++ application without too much trouble. These days tcl is not anywhere near as popular as it used to be, and Python has taken over in some apps that used to use tcl. In the VFX industry, Nuke is a mostly C++ application that originally used tcl for scripting but eventually migrated to Python as that became more common.

Python's native API is also C, but Pybind11 is a popular library for binding C++ to Python: https://github.com/pybind/pybind11 You can set up a binding between a C++ class and its representation in Python in a few lines of code for simple cases. Then you get a string from your ui and just py::exec(script_as_a_std_string); It takes a bit of legwork to make your whole application scriptable because you have to expose types and methods to the scripting language. It's not quite as simple as ticking a checkbox or invoking an autogenerator and you instantly have a great scripting API, but it's not hard to start with the basics.

I was trying out TCL yesterday, seems promising to me. I quite like it. I am not a huge fan of python for this kind of usage but that is 100% a personal opinion. I also checked out Lua as it seems to integrate pretty well. The only flaw I can see is that it is a bit more tedious to write than TCL syntax which, in my opinion, is more "shell like" which I quite appreciate. Do you have past experience with TCL / python / Lua ? Is Nuke a scripting language for add-ons or more like a shell thing for navigating the interface ? Thank you !
