This is a binding of the C++ game and multimedia library SFML (Simple and Fast Multimedia Library), developed by Laurent Gomila, for Julia. SFML is often used for game development but it can be used for anything graphics-related.

It also has audio libraries and networking libraries.

There is currently almost complete support for graphics, great support for audio, and complete support for network.

SFML.jl works on Mac OS X, Linux, and Windows.

Take a look at the examples folder to see some usage examples.

For much larger examples (games) see these two examples: Jumping Game and Space Shooter (this one is more complex).

You can view a talk I gave about SFML.jl at JuliaCon 2015 here. All the demos that I used in that talk are available in the JuliaCon-SFML repository.

To install on any OS, run:

julia> Pkg.add("SFML")

If you want to install the master version use:

julia> Pkg.clone("SFML")
julia> Pkg.build("SFML")

Please make sure you have Glibc 2.14 installed, and let me know if there are any build problems on Linux (I don't use Linux very much). The Linux binaries don't come with any of the dependencies so you have to install them yourself. Here is the list:

• pthread
• opengl
• xlib
• xrandr
• freetype
• glew
• jpeg
• sndfile
• openal

On Debian you can install the package libsfml-dev which will also install all dependencies. You can also run the commands here (you don't need to install cmake-gui).

It is very simple to take a screen shot using SFML. Just use screenshot(window, filename).

You can also take a screenshot and store it in an Image object without saving the image using image = capture(window)

To create a gif, you must have imagemagick installed.

Making gifs is only slightly more complicated. You can use the make_gif(window, width, height, duration, filename, delay) function (duration and delay are in seconds).

When you run the program, it will asynchronously create the gif and will give you constant feedback in the console. If you don't see anything in the console, add a sleep(0) declaration at the start of the animation loop to allow Julia time to switch between the processes.

The gif creation is done when it says Created gif XXX.gif.

• SoundStreams
• SoundStreamRecorders
• SFML threads (pthreads)
• Transforms

For the first three, we will probably have to wait for Julia to support multithreading.
