What does HackerNews think of tinycc?

Here's an example that uses raylib (GUI library), without any extra bindings/build step: https://github.com/theoparis/bunray/blob/main/src/example.ts

bun:ffi works by embedding TinyCC - https://github.com/TinyCC/tinycc and then just-in-time compiling C functions that perform type conversions from JavaScript <> C ABI and back. It's faster than node.js' napi (which bun also supports) because it avoids the dynamic library overhead via doing type conversions inline.

For bun, I really wanted something simpler than napi without the performance drawbacks of libffi.

If you want to see the generated C bindings, you can do this:

    import { viewSource } from "bun:ffi";

    console.log(
        viewSource(
            {
            hello_world: {
                returns: "float",
                args: ["float"],
            },
            },
            false
        )[0]
    );

There has been some continued development of tcc; the GitHub repository here has changes through April 2016: https://github.com/TinyCC/tinycc
