How to use GFM?

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

      "dependencies": {
        "gfm:math": "~>6.0"

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



Who is using GFM?

Why use GFM?

  • GFM has a changelog and respects SemVer,
  • GFM has low churn and has been maintained since 2012,
  • GFM primarily provides math primitives that are useful for games like vectors/matrices/quaternions in the gfm:math package,
  • Also provide arbitrary sized integers, fixed point numbers, and half-float numbers in gfm:integers,
  • Other subpackages are wrappers: transparent layers that expose the C libraries objects, turn every error code into an D exception and makes it easier to use the library correctly. They do almost nothing and perhaps you don't need them.


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 delete things in GFM that exist elsewhere but better. See http://code.dlang.org to discover lots of useful libraries for your programs.

So you'll find that GFM actually decreases in size over time.
