# Regenerating bindings

In order to update `raylib-d` to work with a newer version of `raylib`, the headers must be regenerated with [dstep].

Three modules should be regenerated: `raylib`, `raymath` and `rlgl`.

Run the following command from the `raylib/src` directory. Note: path/to/raylib-d should be the path to the raylib-d repository that you have on your system.

```
dstep raylib.h raymath.h rlgl.h -o path/to/raylib-d/source/raylib --space-after-function-name=false --skip Vector2 \
    --skip Vector3 --skip Vector4 --skip Quaternion --skip Matrix --skip Rectangle --skip RL_MALLOC --skip RL_CALLOC \
    --skip RL_REALLOC --skip RL_FREE
```

Note: we're skipping a couple symbols because we define them manually in `raylib_types`. We also skip memory functions
because they only have effect when compiling Raylib in C.

Finally, the `raylib.h` file will export as `raylib.d`, but it should be moved to `raylib/package.d`.

After you regenerate them, they won't be ready to use yet. We need to add module declarations and imports at the top
of each module:

```d
module raylib;

public
{
    import raylib.rlgl;
    import raylib.reasings;
    import raylib.raymath;
    import raylib.raymathext;
    import raylib.raylib_types;
    import raylib.binding;
}
```

```d
module raylib.raymath;

import raylib;
```

```d
module raylib.rlgl;

import raylib;
```

Additionally, each of those modules will have an automatically generated `extern (C):` line. We need to find it and
edit it to `extern (C) @nogc nothrow:`.

This should be enough. Run `dub test` and see if it compiles.
