simple-compiler

A simple compiler for a very simple toy language. This is a learning project that focuses on simplicity to keep things easy to understand. There will be things that could be done more efficiently, but that's not the point.

What I want is to write a little compiler with hopefully nothing more than Rust's standard library.

The language

I didn't name it, as that isn't important. The aim is to make a simple language that transpiles to C, making type definition a bit easier. This little snippet:

tipo Circulo(centro: Punto, radio: Real);
tipo Punto(x: Entero, y: Entero);

Will produce this output:

typedef struct Punto {
    long x;
    long y;
} Punto;

typedef struct Circulo {
    Punto centro;
    double radio;
} Circulo;

Note that the order in the input language doesn't matter, it will produce C code that compiles nicely.

Installing

To build simple-compiler you need:

• Rust 1.31.0 or better.
• Cargo

And just run cargo build --release

Inspiration

• The Super Tiny Compiler: Inspired me to do this.
• Writing An Interpreter In Go: Using only the tools in the standard library is an interesting concept.
