The BiDi quest continues.

I now have the ability to wrap an entire paragraph in one go while also having FriBidi tell me the directions.

My initial attempt is going badly. Wrapping the entire paragraph in visual order means that the first wrapped line covers the end of the paragraph.

Back to the drawing board… Seems like wrapping needs to be done in logical order and only the drawing in visual order.

It's a bit of a challenge to call FriBidi at the right time. I'll need to refactor the document layout somewhat so the text renderer has visibility to the full paragraph and can process it in one go. At the moment it's more of a line-based operation, which makes it more challenging to apply alignment (and justification).

Looks like FriBidi is doing its thing!

(i.e., applying the Unicode Bidirectional Algorithm)

Still need to optimize the text handling a bit to avoid repeated processing of static strings, e.g., UI labels. Text selection is also a bit wonky over RTL runs...

HarfBuzz & FriBidi mean a big step forward in supporting complex scripts. The final big issue remaining is expanding the collection of available fonts.

After a while it became evident that trying to write my own text shaping engine would be a monumental project of its own. And since HarfBuzz already exists, quite a waste a time...

So I've gradually been integrating HarfBuzz into Lagrange's text renderer. There are still a few issues with the current set of fonts not containing all combining glyphs.

Next step: FriBidi for dealing with RTL scripts.

#Lagrange is now available as an official Homebrew cask on macOS. 🍺🎉

This is by far the most convenient way to keep the app updated on your Mac.

Fancy a custom #Lagrange UI theme? 😎

In v1.6, UI colors can be customized via a config file.

There is a new #Lagrange iOS TestFlight build with significant improvements: swipe navigation, opening files, and MP3 audio control. Many of the internal changes will be coming to the desktop in v1.6 as usual.

I like this part of debugging where I get to listen to @konpeito for an extended period of time to see whether #Lagrange will start overheating my phone CPU. 🎵🎧

Apple is working towards iCloud Keychain backed public-key-based credentials to replace passwords.

Sounds good! #Gemini client certs demonstrate that crypto-based user authentication is a great solution. Having a secure store for the keys/certs is essential, though.

No idea if I remember to keep this updated. Could always integrate it somehow into the Gemini site. 🤔

Haven’t had time to sit at the computer since Tuesday thanks to a mini vacation. These “forced” breaks do help with getting out of whatever groove I was in and looking at things with a fresh perspective. I’ll probably end up reshuffling my todo list when I resume work again.

That Eagle is a wee bit too detailed to be "smol" but it looks pretty cool. It's based on Apple's Emoji so not an original design... ☺️

🦆 My new font project now has a Git repository: https://codeberg.org/skyjake/smol-emoji

The test page shows that a quarter of Emojis are currently missing in Lagrange: gemini://skyjake.fi/smol-emoji/emoji-test.gmi
