sdl2-link

FFI bindings for SDL 2.0.

sdl2-link provides a fluent API that allows for specifying the native call module and the SDL 2.0 extensions to be loaded. The result of load() is a namespace containing the available functions, constants, macros and structs. The naming follows the SDL 2.0 C API as closely as possible.

• Supports FFI-compatible native call libraries, including fastcall and ffi.
• Supports SDL 2.0 extensions:
  • SDL2_image
  • SDL2_mixer
  • SDL2_ttf

Requirements

• The SDL 2.0 library must be available through the system's library path.
• Supply an FFI-compatible native call libraries via dependency injection.
  • fastcall (Recommended)
  • ffi-napi + ref-napi
  • ffi + ref

Installation

npm install sdl2-link     

Getting Started

SDL 2.0 API

import sdl2link from 'sdl2-link';

const SDL = sdl2link()
    .withFastcall(require('fastcall'))
    .load();

SDL.SDL_Init(SDL.SDL_INIT_VIDEO);

SDL 2.0 Extensions

import sdl2link from 'sdl2-link';

const SDL = sdl2link()
    .withFastcall(require('fastcall'))
    .withTTF()
    .load();

SDL.TTF_Init();
SDL.SDL_Init(SDL.SDL_INIT_VIDEO);

Caveats

Some of the Joystick and GameController APIs are not compatible with fastcall. All these APIs have been separated out into a separate extension that can only be loaded with ffi. If you are using fastcall, you can safely use ffi to load the joystick extension.

SDL 2.0 Documentation

The namespace (object) sdl2-link returns contains constants, structs and functions exactly as they appear in the SDL 2.0 API. Use the official SDL 2.0 documentation for reference.
