cral

This crate is used to generate C code based on AST.

This crate versions 1.0.0 and above is modified based on crustal crate.

This crate has streamlined crustal and added the following content:

• Function pointer.
• __attribute__(()) macro gen.

Remove the following content:

• C++ code gen part.

Exaple : HelloWorld

use cral::*;

let mut scope = Scope::new();
scope.new_include("stdio.h", true);

let mut main_block = Block::new();
main_block.new_expr(Expr::fn_call("printf", vec![Expr::str("Hello World!")]));
scope.new_function("main", Type::void()).set_body(main_block);
scope.to_file("main.c", false).unwrap();

Generated c code

#include<stdio.h>
void main(void) {
    printf("HelloWorld");
}
