    If you have read my earlier posts you know I love multilingual programming. One important part of multilingual programming is how to interface one language with other. Typically this is called FFI or foreign function interface. At the lowest level often there are libraries (aka bindings) to talk across languages or across implementations of same language e.g. libffi. In my undergrad we did a group project where we created language bindings to separate algorithmic part written in python and opencv and X11 logic in c.

    is itself related to the bug in the build script, for dependency. Thus not an issue of your distro/beyond the scope of this bug.

    Well, by this I mean "unfamiliar to me", of course. Lol.

    Actually Lua is something to consider from the point of view of usage: it is an industry standard actually. However, all those small quirks in semantics... and classes can be done in many ways (that is what I understand, via metatables)...

    In ChaiSCript or Wren there is one true way and you are done. You might like it or not, but it leads to less confusion, especially if you use most of the time what is in the mainstream.

    This is by no means a bad thing in itself, it is just about how ergonomic or time-consuming it could be for myself: I just feel more comfortable with ChaiScript, Wren or Squirrel than with Lua. Even AngelsCript is also more similar to what you already have. So when exposing APIs there is much less friction.

    Truth to be told, there is also which looks great and something to consider. It makes binding things quite easier and gives you object-oriented Lua. You could rely on that.

    It was just my subjective choice. There is no 100% right choice. Probably, if I found people that are comfortable with Lua I would use that. But the case is that this is a project of mine as it stands now.

    3) Similiar to 2, but use more common scripting languages: chai, cs-script, sol2 (c++ framework to embed lua)
