I think Richard mentioned that he was using a SDL2 platform for one of his demos of Roc. I can't seem to find what talk it was. :(
Does anyone know if that (or some SDL) platform/demo is available on GH somewhere?
David Dunn (Aug 16 2022 at 12:43):@Andreas T Jonsson The fireworks demo in his recent Philly ETE talk used an SDL2 platform. Is this the one you're looking for?
Can't see it in the roc-lang Github org, but Richard mentioned in that talk that @Brendan Hansknecht made the fireworks demo (can't find it on their GH profile either), so they might know more
Brendan Hansknecht (Aug 16 2022 at 12:55):https://github.com/bhansconnect/roc-ecs
Also, some info in #beginners > ECS
Brendan Hansknecht (Aug 16 2022 at 12:58):Might be slightly out of date from current Roc, but i can definitely update it if needed.
Luke Boswell (Oct 31 2022 at 23:01):@Brendan Hansknecht I'm wondering how you went with the ECS experiment. I've been researching different ideas for the gui platform. One of the ideas I have is to implement a lot of the functionality in Roc. For example writing a pure Roc FlexBox layout using a Roc interface module. I'm just not entirely sure yet how that would interface with the platform. I definitely feel like some kind of data oriented architecture similar to ecs would be a good idea. I imagine the layout is just a system for the ui widgets. Looking for any pointers based on your experience.
Anton (Nov 01 2022 at 07:58):We have discussed ECS for the editor before but I'm not sure if you can view messages from before you joined. Does this link work for you @Luke Boswell?
Luke Boswell (Nov 01 2022 at 09:36):Thanks @Anton I hadn't seen that thread. I concur with @Matthias Devlamynck and feel that it is worthwhile investigating further. I have been coming from my research into understanding Action-State and how that might be implemented in practice. With effects, and other Roc features I think it could make ECS really good to work with. It feels like it could fit well together, particularly with dynamically loading plugins. For example I was playing with ideas to support different layout libraries which you can swap out, i.e. flexbox. If we have a drawable widget then maybe it has position data which these libraries can update in the same way. Basically I have been looking for ideas about how we can provide primitives in the platform which play nicely with Roc modules to compose functionality.
Anton (Nov 01 2022 at 09:57):Excellent :) Being able to swap out layout libs sounds like a smart move!
