my-yapl

This is a complete compiler for a custom C-like programming language, created for educational purposes. It generates assembly code for the MIX architecture and is compatible with any emulator that supports it.

Check the examples directory to take an idea of yapl's syntax or refer to this document to find more information about MIX.

Example

This is how the yapl language looks like

int main() {
    int a = 2, b;
    int c, d = a;
    return a + d;
}

And this is the resulting MIX assembly

Build

I've also developed the utility script build.js to streamline the building process, offering additional features such as improved error highlighting and AST tree visualization.
