it's a thing I guess Also, this program has been tested on x86_64-linux and aarch64-macos. The prompt (REPL) definitely won't work on Windows, and the rest of the program hasn't been tested (and I can't be bothered to check for anything POSIX-specific).

documentation

Not much, but there is a syntax guide here if you want to read it.

building

make

Then run build/mml --help to display the command-line options.

NEW!

If you have zig installed, you can use zig build to build the library and executable. Here are the commands:

zig build

You can run zig build -Doptimize=ReleaseFast to get more optimization. zig build also allows easy cross-compilation; this page has some more information (should still be up to date-ish). This will automatically build the static library as well (every source file except src/main.c and src/prompt.c).

library documentation

It's not much of a library, but it is built to be easily extendable (hopefully that's true). A minimal example:

#include <stdint.h>

#include "mml/mml.h"

int32_t main(void)
{
	MML_state *state = MML_init_state();

	const char *s = "cos{1.5pi} == 0.0";
	MML_Value ret = MML_eval_parse(state, s);
	MML_println_typedval(state, &ret);

	MML_cleanup_state(state);

	return 0;
}

And it can be compiled with this command (assuming you've run make shared_lib or make static_lib, are currently in the root directory, and named the example file test.c):

gcc -o test test.c -Iincl -Lbuild -lmml -lm

The shared object file is a bit finnicky, so if you link with the shared library, you'll probably have to do this (the above should work on OS X, though):

gcc -o test test.c -Iincl build/libmml.so
