Jinx VS vigil

Check out jinx https://jamesboer.github.io/Jinx/

Don't get me wrong, I'm a big fan of automated tests where it makes sense. I wrote a scripting language that I use for my personal game projects, and I never would have been able to do it if it weren't for the battery of tests for every feature, error, and corner case I could think of. But games are rarely like other software, with hard rules about what is "correct" or "incorrect". And it would be a nightmare to try to keep up with designers, constantly tweaking and tuning, so what's "correct" is literally a day to day, constantly moving target.

A second trial for you might be Jinx. Depending on your definition of procedural, Jinx is 100% only procedural. https://jamesboer.github.io/Jinx/

Jinx (embeddable scripting language) works as following:

Feel free to look at my own interpreter, written in modern C++. You're welcome to ask me if you have any questions.

I use my own scripting language more like content, especially for things like one-off events and behaviors. Example: scripting special behaviors for a boss fight, or a room with a unique trap in it, or any other sort of one-off behavior that would be overkill for C++, but too complex for most other types of data-driven content. These days, visual scripting also helps to fill in these gaps between content and procedure.

You're welcome to look at my scripting language Jinx, written in modern C++. Just let me know if you have specific questions. Data flow is JxLexer.cpp -> JxParser.cpp -> JxScript.cpp. Most everything else is implementation details. Also, note the parer is pretty complex, mostly because Jinx has a crazily flexible syntax for functions.

Feel free to look at Jinx if you want an example of what I consider a fairly easy-to-use and integrate scripting system. Obviously, I'm a bit biased since I wrote it.

If you're working in UTF-8 internally, you could just write your own UTF-16 to UTF-8 conversion functions to convert strings at API boundaries. I did this in my scripting language because I didn't want to bring in dependencies.

Reminds me of Vigil. https://github.com/munificent/vigil

Should it be a variation on another programming language, so something that just looks through another language's code and modifies it a little bit like this: https://github.com/munificent/vigil/ or should it have a fully fleshed out parser, lexer, interpreter/compiler etc.?

I code in Vigil. If some part of the code throws an unhandled exception it gets automatically deleted. Bug free app in few invocations!

This reminds me of Vigil, a very odd language derived from python that deletes your code if you break your promises.

Easy, just program in Vigil

Sounds kind of like vigil, where things that are wrong are duly punished

Vigil, but for moral rather than practical reasons.
