pixelfold - Pixelflut server written in Haskell with SDL

Requirements

• Haskell Stack, easiest installed via GHCup
• SDL2 and SDL2 development Headers (Example for Fedora)

  dnf install SDL2 SDL2-devel
  

Installation

git clone https://github.com/heiziff/pixelfold.git
cd pixelfold
stack build

• Binaries compiled via stack build are only runnable from the project directory. If you want to be able to run pixelfold from anywhere, consider using stack install

Usage

stack exec pixelfold-exe <portnumber>

The server then listens for TCP messages on Port <portnumber> or Port 4242, if none was specified.

The server accepts the following Commands:

• Draw: colors the pixel at position (pos_x, pos_y) with the 32-bit color value RRGGBBAA (in hex)

  • Expects messages with the following format: "Draw (pos_x,pos_y) 0xRRGGBBAA\n"

• Help: Sends back the help text
