README

reflex-sdl2

This is a very minimal host for running reflex apps using sdl2.

installation

Writing and running sdl2 apps requires version 2 of the awesome SDL library.

macOS

Using homebrew…

brew install sdl2

Ubuntu

The sdl2 bindings 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

with Stack

This project uses stack for building. From the project directory:

stack build

with Nix

You can also build this using project using Nix4.

There are two ways to proceed.

If you're not a Nix user, the best way to get started would be to clone the reflex-platform somewhere:

git clone https://github.com/reflex-frp/reflex-platform

After that you can ues the work-on script from the project directory to open a shell with an environment set up for developing this project:

PATH_TO_REFLEX_PLATFORM/work-on ghc ./reflex-sdl2.nix

If you're already using Nix, then you can open the same shell with:

nix-shell

In either case, once you are in that shell you can build the project with:

cabal build

examples

You can view an example using the built-in 2d renderer in app/Main.hs. To run the example do:

stack build
stack exec reflex-sdl2-exe

or from a Nix shell:

cabal run reflex-sdl2-exe
