metagen_bhl_bind/README.md

This package is used for code generation of bhl2 bindings for C# using Twig templates

Here the example of bindings declaration:

    func Debug(
      @bhl_native_prefix:BitGames.Logs.Log.Debug(..)
      msg : string
    )

    func Error(
      @bhl_native_prefix:BitGames.Logs.Log.Error(..)
      msg : string
    )

    func Time(
      @bhl_native_prefix:Time.time
    ) : float

    struct Vector2
      @bhl_native_class:Vector2 @bhl_custom_rw @bhl_no_itype

      x : float
      y : float

      magnitude     : float @bhl_set:0
      sqrMagnitude  : float @bhl_set:0
      normalized    : Vector2 @bhl_set:0

      func Mult(
        @bhl_bin_op:"*" @bhl_static
        self : Vector2
        v : float
      ) : Vector2
    end


Usage example:

    $twig = \bhl_bind\get_twig();
    $meta = \bhl_bind\prepare_meta($meta);

    file_put_contents('autobind.cs', 
      $twig->render("codegen_autobind.twig", 
        [
         'imports' => ['UnityEngine'], 
         'meta' => $meta
        ]
      )
    );

    file_put_contents('types.cs', 
      $twig->render("codegen_types.twig", 
        [
         'meta' => $meta
        ]
      )
    );
