# kproc-macros

This is a design document where it is described a proposal
to integrate a library in the Linux kernel where it is possible
parser easly rust code to make easy the parsing of a procedural
macros

For now there is a support only for the following procedural macros

- [ ] Derive macro, usually star with `#[derive(InitPin)]`
- [ ] Function-like macro, can unlock [feature to simplify the module writing](https://rust-for-linux.zulipchat.com/#narrow/stream/288089-General/topic/init.20and.20drop.20module.20with.20a.20procedural.20macro)
- [ ] Attribute macro

## Implementation

Draft implementation available at https://codeberg.org/vincenzopalazzo/kproc-macros

fn parse(toks_stream) -> .. {
    let ast = parse_struct!(toks_stream);
    match ast {
        Struct(_, _, attr) => {}
    }
    
    let fun = parse_fn!(..);
}

### For Driver

struct HelloModule;

#[module_init]
fn init(_name: &'static CStr, _module: &'static ThisModule) -> Result<HelloModule> {
        pr_info!("Hello world\n");
        Ok(HelloModule)
    }
}
