cpreprocess

Stupid and cursed Rust procedural macro that runs a C preprocessor on the input

Usage

[dependencies]
cpreprocess = "*"

Example

fn main() {
    cpreprocess::cpreprocess!(r#"
        #define MACRO(NAME) fn print_ ## NAME () { println!("hello world"); }

        MACRO(hello_world)

        print_hello_world()
    "#)
}

Nightly

If you're using the Rust nightly compiler, you can use the macro without a string literal. Just enable the nightly Cargo feature for this crate.

I think this is largely experimental, as it relies on a non-100% accurate method of extracting the contents of the macro.

fn main() {
    cpreprocess::cpreprocess! {
        #define MACRO(NAME) fn print_ ## NAME () { println!("hello world"); }

        MACRO(hello_world)

        print_hello_world()
	}
}
