14003 :: Coluber — a compiled language written in Nim with C/Nim/Python/JS FFI

  Hi Nim community! I built Coluber, a small compiled programming language whose compiler is written entirely in Nim.

  It features:

  • Python/Nim-inspired indentation syntax
  • Static type inference, compiles to C via GCC/TCC
  • Multi-language FFI: call C, Nim, Python, and JS from one source file
  • Zero-overhead arena memory model

  Repo: https://codeberg.org/foliagetree/coluber

  Would love feedback on the compiler architecture (src/) and the FFI approach!

  Zero-overhead arena memory model

  Oh god no........... :P

  Cause nothing screams "zero overhead" more than "cannot ever free intermediate results and unbounded memory consumption, enjoy".

  Thanks creator for reply, nim is a great language, it really need more optimizes & improvements

  Don't get me wrong, writing a compiler is always very rewarding and one with static typing and an indentation based syntax tends to win my heart. ;-)

  Yeah, that's true
