sciter VS gio

> wondering if css and svg could be used as abstraction over graphics and UI libraries

There's another project called Sciter that uses CSS to target native graphics libraries: https://sciter.com

> I wonder how hard it was to implement css. I've heard it can be pretty complex.

It was hard, but the biggest barrier is the obscurity of the knowledge.

Text layout is the hardest, because working with glyphs and iterating them in reverse for RTL is brain-breaking. And line wrapping gets really complicated. It's also the most obscure because nobody has written down everything you need to know in one place. After I finished block layout early on, I had to stop for a couple of years (only working a few hours a week though) and learn all of the ins, outs, dos, and don'ts around shaping and itemizing text. A lot of that I learned by reading Pango's [1] source code, and a lot I pieced together from Google searches.

But other than that, the W3C specifications cover almost everything. The CSS2 standard [2] is one of the most beautiful things I've ever read. It's internally consistent, concise, and obviously the result of years of deliberation, trial and error. (CSS3 is great, but CSS2 is the bedrock for everything).

otherwise, if we have only retained mode as in browsers, we will need to modify the DOM heavily and create temporary elements for handles.

I've still never used it but I've long been curious about Sciter:

These bullet points are exactly what I did in Sciter (https://sciter.com)

- Windowing

-- Tabs

-- Menus

-- Painting

-- Animation

-- Text

-The compositor

-Handling input

-- Pointer input

-- Keyboard input

- Accessibility

- Internationalization and localization

- Cross-platform APIs

- The web view

- Native look and feel

On top of that DOM and CSS implementations to achieve declarative UI. And JS as a languuage behind UI - declarative in some sense way of defining UI behavior.

I'm not sure if it can support all the libraries but yes it can be used to make desktop apps. Theres also Sciter.

Gio UI is an immediate-mode UI, and immediate-mode UIs map very nicely to Rust. egui is quite easy to use. https://www.egui.rs/

I've been writing a WASM app using gio & I found myself wanting for a simplified web library. In addition I drew some inspiration from leptos server functions. A friend of mine mentioned it has some similarities with next.js

I am building the same but with golang and https://gioui.org/

This release of Gonum/plot is in sync with Gonum-v0.13.0 and updates the vg/vggio backend to the latest Gio API.

Historically, C++. Today, (unfortunately) a lot of (non-game) desktop apps are written in HTML/CSS/JS using Electron. There are projects like Fyne and GIO that aim to make Go a viable language for building large-scale performant desktop apps. My open-source hobby project Supersonic is a music player app built using Fyne.

It’s actually extremely easy, if you use one of the actively developed options like https://fyne.io or https://gioui.org for example. Flutter’s Dart may help with real-time hacking of UI but Go produces better code in the long run!
