I built a programming language from scratch in C++. It has a C-like syntax with modern features: structs, enums, arrays, pointers, and a module system for splitting code across files.

The compiler pipeline goes: lexer - parser - semantic analyzer - LLVM IR - native binary.

I also wrote a standard library in C that Techlang functions can bind to using an extern keyword.

Next up is a GPU compute companion language that can call into Techlang code natively since both target LLVM IR. Haven't seen anyone else do this.
