I'm honored to be invited again to give a keynote talk at ELS'26 in Kraków. See you there :)

Streaming #McCLIM development in one hour.

I will be attempting a proof-of-concept integration of my opengl medium (WIP) and the upstream SDL2 backend (also WIP). I hope I've been flexible enough but it could end with many TODOs :D

#CommonLisp #Lisp #OpenGL

I plan on streaming #McCLIM dev on 2026-04-10 at 10am CDT/ 15:00 UTC (when this toot is about 12h old)

I'm now too curious, so I'm going to attempt to use my existing opengl medium with the upstream SDL2 backend branch and see whether I've made it flexible enough.

SDL2 backend has now configurable DPI.

I just realized I won't be able to stream when I usually do tomorrow, so I'm going to try to today. It's short notice, yet again, apologies...but about 1 hour from posting time, 10am CDT / 16:00 UTC, I get started.

I plan on updating with upstream #McCLIM and previewing those, then will take stock of where I want to next focus.

I'm going to throw some alpha stuff into the release to avoid unnecessary pestering :)

#McCLIM #lisp #sdl2

Things got a little screwy, but I added parsing for the historic #sixel notation.

(#1# A B C D E -) (#2# A B C D E $))

That output e.g. renders sixels in a #mcclim application pane & also makes it clear why that macro looks how it does. #commonLisp #programming #unironic #retrocomputing
