Let's take a look at a simple example (this example is without using .di-files):
https://github.com/Mashpoe/c-hashmap

Clone it and put the files somewhere convenient.

Now, let's try using it.

In this example map.c and app.d are located in the same directory.

import std.stdio : writeln;

// Use map.c
import map;

import std.string : toStringz;

alias c = toStringz;

void main()
{
	hashmap* m = hashmap_create();

	string key = "hello";

	hashmap_set(m, key.c, key.length, 400);

	uintptr_t result;

	if (hashmap_get(m, key.c, key.length, &result))
	{
		writeln(key, " = ", cast(int) result);
	}
	else
	{
		writeln("Could not locate entry ", key);
	}
}

If you have your paths setup correctly, you can now run

dmd map.c app.d

dmd has now produced an executable. Run it and see the results.

Nice. Now if we also could get autocompletion etc it would be even better. It's probably possible with some tweaks already, but I didn't look into it.

Auto-complete works if you can build a DI file out of it.

Yeah, it works. Would just be nice.
