The Crom Compiler

This repo houses a compiler implementation for the Crom programming language.

Crom is under-construction and actively being developed.

What is Crom?

Crom is a statically-typed programming language that borrows heavily from C. Crom aims to improve certain areas of C and add QOL features, while maintaining a familiar syntax.

Some existing and planned features include:

• Terse and explicitly-sized numeric types (i8, u32, f64)
• Binary literals for easier bitwise manipulation and/or expressiveness
• Out-of-the-box support for strings (e.g. concatenation, length)
• First class functions
• Tail call optimization
• No need for header files (as found in C)
• No array-to-pointer decay (as found in C)
• Generics
• Multiline string support
• Default function arguments

---

Roadmap

• Lexer
• Parser
• Type Checker
• IR generation (in progress)
• Code generation
• Optimization

Syntax examples

// Structs and functions
struct Vector2 {
  i64 x;
  i64 y;
}

V2Add(struct Vector2 a, struct Vector2 b) :: struct Vector2 {
  struct Vector2 sum = { a.x + b.x, a.y + b.y };
  return sum;
}

struct Vector2 position = { 100, 200 };
struct Vector2 velocity = { 10, -5 };

position = V2Add(position, velocity);

// Binary literals
u8 a = `1000 1000`;
u8 b = `0111 0111`;

bool equal = (a | b) == `1111 1111`;
