@geekysteven@beige.party triggering for #Nashville but I'd like to see this (but still not in person)

Had some success implementing the beginnings of #Wayland 's text-input-v3 preedit event in #McCLIM today on-stream.

IME input is feeling nicer but still not good enough for real use.

I plan to stream #McCLIM things in approx. 40min at 10:30am CDT / 15:30 UTC (2026-06-05)

I'll review my current IME state and then attempt implementing #Wayland text-input-v3 protocol's preedit event.

I plan on streaming #McCLIM things in approx 2h13m from now at 11:30 CDT / 16:30 UTC.

Now that text is rendering better, I want to focus on the #Wayland IME support (text-input-v3 part of the protocol). The foundation is there already but I'm seeing errors related to different McCLIM gadgets and my want to use STREAM-CURSOR-POSITION.

I plan on streaming #McCLIM and #OpenGL things in about 30min at 9am CDT / 14:00 UTC.

Today's plan is to fix the line height issue in my SDF font rendering and hopefully implement the line direction feature. The anxiety is, like a Rubik's cube, I'll have to break some things before it gets better.

After lots of IRL interruptions, I think I've finally got the SDF font rendering in my #McCLIM #Wayland #OpenGL backend working with shelf allocating texture atlases. In the process I ended up with a TTF one too (uses the existing glyph rendering that CLX-FB uses).

My comment at end of second video is not to throw shade on CLX backend but rather to also show scaling properties of SDFs. No shaders are used so, it's still not top-quality SDF

There's a lot of neat things to chat about from this week before getting to work on #McCLIM but I'm not sure if I'll be able to stream today. I have some aging-parent care I need to help with.

If I do get a chance, it will likely be later than normal and with little more than the normal twitch notification. Sorry it's been a rough couple of weeks for streaming Lisp.

I'll be streaming #McCLIM things at 12pm CDT / 17:00 UTC/ when this post is about 1h45m old.

https://www.twitch.tv/endparen

I plan on tracking down bugs preventing my #OpenGL renderer being more useful for other FFI backends. i.e. the preview/alpha SDL2 backend recently merged upstream.

Streaming #McCLIM development in one hour.

https://www.twitch.tv/endparen

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

@Natasha_Jay@tech.lgbt ooh survivorship bias

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

https://www.twitch.tv/endparen

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.

Sadly I had to delete the VOD for fear I recorded some PII. Luckily it was a false alarm but the video remains deleted since I can't upload it back.

charliemac @charliemac@mastodon.social · Apr 02, 2026

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.

https://www.twitch.tv/endparen

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

@jackdaniel hah, no, I meant attracting more pestering. Sorry that wasn't clear. I'm excited for it myself! Moreso for having another interactive backend in the main branch.

@jackdaniel I was briefly conflicted whether to boost 😆

@hell https://planet.emacslife.com/ is a good way to find people blogging emacs. I've started using emacs' built-in (one of many) newsticker for my feed reading

slightly delayed; unexpected guix update happening.

I plan on streaming #McCLIM and #OpenGL things in approx. 90 min from this post time, 2026-03-20 12pm CDT/ 17:00 UTC.

https://www.twitch.tv/endparen

I plan on testing out the just-merged input-editing work from upstream and working out some of the remaining bugs with the text atlas using the mcclim-truetype backend. It would be great if I was in a place to start on the SDF side by the end.
