TJS = tinyc compiler + quickjs

Mix the power of two worlds, allows you to call c function in js (inline).

Toy project, no guarantee of safety, use at your own risk.

Example

// yes, it support es-module
import { Compiler } from "builtin:c";
// initialize compiler
const compiler = new Compiler("memory");
// link to user32 to use MessageBoxA
compiler.link("user32");
// and place your c code inline
compiler.compile(String.raw`
#define UNICODE
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
void msgbox(PCWSTR text) {
  MessageBox(NULL, text, L"from js", 0);
}
`);
// and relocate the function
const obj = compiler.relocate({
  msgbox: "w"
});
obj.msgbox(`from ${import.meta.url}`);

About relocate syntax

Basic form: object { funcname: desc_string }

example:

• "ii" -> (int, int) => void
• "dd!d" -> (double, double) => double
• "i[i]!i" -> (int, (int) => int) => int
• "[s]!i" -> ((string) => int) => int

Symbol	Type in c	Type in js	parameter	result	callback
i	int32_t	number	yes	yes	yes
d	double	number	yes	yes	yes
s	char *	string	yes	no	yes
w	wchar_t *	string	yes	no	yes
v	{ void *, size_t }	ArrayBuffer	yes	no	yes
b	int64_t	bigint	yes	yes	yes
p	void *	bigint	yes	yes	yes
[]	opaque type	function	yes	no	no

For typescript user: We also provide a d.ts files for type-checking, requires typescript 4.1+.
