Dear community, I'd like to learn how to make my own game scripting language. It would not be as complex as GDScript, and neither compete with it, but it's just for learning (any minimalist scripting language, even similar to Lua or so, would suffice).
So, what I'm asking here is: is there any book I should read to learn how to create my barebone scripting language?
Sideways, how was the GDScript firstly created?
Thanks to who will answer.
