I would like to discuss RRLL (Racket Rogue-Like Library) at the meetup. The idea has been getting shaped over the past two months (thanks to @simonls, @spdegabrielle and @sschwarzer) and although is far from even pre-alpha state, I already have some nice concepts implemented and I would definitely like to hear some feedback. The current snapshot of whatever I am working on will be published prior to the meetup, so anyone can have a look at the code. The idea is to create a library for writing roguelikes in Racket using fully functional approach. That means making it universe/big-bang-like. Including movement/combat/animation system and DSL for programming non-player actors. So far I have: - four implementations of functional two-dimensional grids with tile set / ref operations having O(1), O(log n) or O(n) time/memory complexity. Of course each implementation is more efficient for different operations, - a simple maze and caves generator is there to test it, - sgl-based interface, - visibility algorithm, - tiles rendering with lighting, - sprites rendering, - simple graphical assets loading, - simple text printing capability, - random-first-search algorithm for determining connected components, and - Dijkstra's algorithm for finding the shortest path in given grid. One picture is worth a thousand words they say: ![image](https://global.discourse-cdn.com/free1/uploads/racket/original/1X/dd8fb837477b271184ea28627cee9885a23e8e42.png) If you think this might draw you to roguelike development in Racket, please, show up and let me know your needs and/or ideas. ---

13 hours to go 😉 Here's the code: [Dominik Joe Pantůček / RRLL Ideas · GitLab](https://gitlab.com/racketeer/rrll-ideas) As I am out in the field, it might be a bit challenging to connect, but that's the plan.
