Scriptable (lua) desktop background UI based on Skia

About Me

I'm a software developer based in Croatia who likes hacking on a wide range of stuff'n'things™.

I have a web portfolio that summarizes some of my projects and achievements. I often fork things to remind myself to contribute to the existing projects instead of rolling my own, but I often forget - so they're not the best indicator of what I've worked on.

I love FOSS, experimenting with new stuff, trying to piece together pieces that don't fit, and small kittens and puppies.

I'm interested game (engine) development, procedural stuffs, and systems programming. I can discuss (programming) languages ad nauseam.

clunky's Issues

Design component/scripting interface

Components should be easily composable and reusable.

Entry script should provide globals containing information about:

• Display layer information
  • Position, default size and anchoring.
  • Display layer style
    • Transparency, Blur?
    • Background, Border, ...
  • Contents
    • Layouts/components

Layouting

• taffy can be used for layouting and provides most of what's needed for complex layouts.

Basic rendering support

Decide on the rendering sub-system that will be used. Using an existing rasterizer seems like the best option as it grants biggest freedom while creating components.

Most Rust implementations have some limitations, but are much thinner than Skia. The limitations are not that severe as in most cases they can be worked around (e.g. line dashing).

Some options are:

• skia (GPU/CPU)
• tiny-skia (CPU)
• femtovg (GPU)
• cairo (CPU)

If there's a fullscreen mode application running, rendering needs to pause.

Text

Document level text rendering isn't a priority. cosmic-text seems like a very good option.

Keyboard input on Wayland

Setting surface .set_keyboard_interactivity(KeyboardInteractivity::OnDemand); seems to permanently capture keyboard focus on Hyprland. Though this could be a Hyprland bug.

Should be debugged with other WMs in the future.
