# The Core Language # The Core Language
A statically typed systems programming language that **you shouldn't use**, I'm NOT joking. A statically typed systems programming language that **you shouldn't use**.
I mark it as complete, it's pretty buggy but I had a lot of fun making it.
Learned a lot about language design and implementation, very worthwhile experience.
If you are intersted in programming languages, checkout bottom of the readme (there are useful resources there!).
The language is usable,
it lacks a macro system/generics for full convenience. It can be combined with C preprocessor
or python but where is fun in that?
Generics seem easy but I wanted something more powerful with compile time tree rewriting capabilities
but thats complicated, I dont have good design for that. :(
The basic premise of the language is simplicity and debuggability, The basic premise of the language is simplicity and debuggability,
reinforcing already useful ideas from C,C++,Go,Odin,Jai and shaving off round edges. In the future it might become a single/two file, easily embeddable library language with optional fixed-size allocation scheme and stb libraries style design. reinforcing already useful ideas from C,C++,Go,Odin,Jai and shaving off round edges.
