janet-rs-sys
Raw Rust bindings to the Janet Programming Language
use janet_rs_sys::*;
use std::ffi::*;
fn main()
{
let result = unsafe { janet_init() };
assert_eq!(result, 0);
let env = unsafe { janet_core_env(std::ptr::null_mut()) };
let code =
CString::new(r#"(print "Hello World!")"#).unwrap().as_c_str().as_ptr();
let file = CString::new("hello-world.janet").unwrap().as_c_str().as_ptr();
let result =
unsafe { janet_dostring(env, code, file, std::ptr::null_mut()) };
assert_eq!(result, 0);
}
Note
Currently, these bindings only work on Windows because of some strange errors
arising from bindgen using u128
on the FFI layer and subsequent warnings from
the compiler because of this. It's likely that there isn't much left to do to
get a Linux & MacOS version of this working but as of right now it proved too
difficult to work out what was wrong on Nix platforms.
Dependencies
These are required when using janet-rs-sys
in a project:
- Meson: Builds Janet
- Ninja: Used by Meson
- Clang: Bindgen uses libclang
Dev Dependencies
