[![Build status](https://github.com/antonijn/cheax/actions/workflows/build-test.yml/badge.svg)](https://github.com/antonijn/cheax/actions)

A Lisp dialect that looks a bit like Haskell. Designed for easy

interoperability with C/C++.

Installation

------------

```sh

$ mkdir build && cd build && cmake .. && make

# make install

```

Language demo

-------------

![Made with VHS](https://vhs.charm.sh/vhs-4S0HmQsFAYuSxQuZ6i1HJE.gif)

C API example

-------------

```C

#include 

#include 

int main(void)

{

	int result;

	CHEAX *c = cheax_init();

	/* Load some "unsafe" functions, e.g. file io and the program

	 * exit function */

	cheax_load_feature(c, "all");

	/* Make sure cheax doesn't cause a stack overflow */

	cheax_config_int(c, "stack-limit", 4096);

	/* Load the standard library */

	if (cheax_load_prelude(c) < 0) {

		/* Display error message on behalf of "example" program */

		cheax_perror(c, "example");

		return EXIT_FAILURE;

	}

	/* Synchronize variable `result' with the eponymous symbol

	 * in cheax */

	cheax_sync_int(c, "result", &result, 0);

	cheax_eval(c, cheax_readstr(c, "(set result (sum (.. 1 100)))"));

	cheax_destroy(c);

	printf("1 + 2 + ... + 100 = %d\n", result);

	return 0;

}

```
