# reflex-sdl2

This is a very minimal host for running [reflex][2] apps using [sdl2][0].

## installation

Writing and running [sdl2][0] apps requires version 2 of the awesome [SDL][1]
library.

### macOS

Using [homebrew](https://brew.sh/)...

    brew install sdl2

### Ubuntu

The [sdl2 bindings][0] require SDL >= 2.0.4, or for special instructions
to be followed. Assuming you're on `Ubuntu >= 16.04`, you can run

    apt-get install libsdl2-dev

otherwise please visit the org page above and install via their README.

## building

This project uses [stack][3] for building. From the project directory:

    stack build

## examples

You can view an example using the built-in 2d renderer in
[app/Main.hs](https://github.com/schell/reflex-sdl2/blob/master/app/Main.hs).
To run the example do:

    stack build
    stack exec reflex-sdl2-exe
