gfm 1.3.2

What's this?

GFM is a feature-rich library to ease the creation of video games / multimedia applications with the D programming language.

How to use GFM?

Add the sub-package you are interested in in your dub.json:

   {
      "dependencies": {
        "gfm:math": "==1.1.8"
      }
   }

See the examples/ directory, or https://github.com/p0nce/aliasthis as an example of a game.

Warning: you need at least DUB 0.9.22-rc1 to use GFM

Dependencies

You absolutely don't need to use the whole of GFM. Pick just what you need to minimize the amount of dependencies.

There is an ongoing work to reduce package dependencies and delete things in GFM that exist elsewhere but better.

Design goals

• Give more power to the library user providing code that will probably need to be written anyway.
• Each module / sub-package is maximally decoupled.
• Logging interface for everything which need to output messages.
• Correctness and functionality are favoured over speed.
• Wrappers are lightweight layers that expose the C libraries objects, turn every error code into an D exception and makes it easier to use the library correctly.
• As much as possible, GFM emit warnings when something goes wrong, try to recover when it makes sense and log every problem.

Why use GFM?

In the D1 days, I created several multimedia applications:

• Vibrant: http://www.gamesfrommars.fr/vibrant/
• Wormhol: http://www.gamesfrommars.fr/wormhol/
• Extatique: http://www.pouet.net/prod.php?which=53942
• The Orange Guy: http://www.pouet.net/prod.php?which=52780
• SeamzGood: http://www.dsource.org/projects/seamzgood

This all came with some insight with how to do OpenGL applications in D. During this time I became acutely aware that my quick & dirty coding style wouldn't cut it in the long run. GFM is the clean successor library to the unfortunate code I was using at this time.
