swift-cross-ui VS owlkettle

For another SwiftUI-like wrapper, see also https://github.com/stackotter/swift-cross-ui (used by Adawaita to generate widgets, and mentioned in other comments).

The key premise of this approach is to provide a SwiftUI-like declarative wrapper around Gnome functionality. It's unclear what it adds over swift-cross-ui.

SwiftUI itself has growing pains mainly around being on the right thread for processing/updates and getting data binding right.

Blog entries on swift.org or from Apple tend to be little demos that show the happy path, but when discussing new frameworks (like a Gnome wrapper) or platforms (like the recent embedded), I'd like more demonstration that the authors understand and address key issues and will sustain development. Cross-platform UI frameworks get complicated quickly and have a long tail of issues (cf Flutter, Java/Eclipse, et al) that can be blockers for clients/users. For Swift it doesn't help to have multiple concurrency models and obviously different behaviors on apple platforms and Linux (where UI is not officially tested).

Some interesting stuff happening here [1] and here [2] too.

This is really cool! I love the JSX-like approach to UI and it's a shame it's not so common on desktop. https://github.com/can-lehmann/owlkettle is the only thing I find comparable.

Ones that have not been mentioned so far:

nlvm is an unofficial LLVM backend: https://github.com/arnetheduck/nlvm

npeg lets you write PEGs inline in almost normal PEG notation: https://github.com/zevv/npeg

futhark provides for much more automatic C interop: https://github.com/PMunch/futhark

nimpy allows calling Python code from Nim and vice versa: https://github.com/yglukhov/nimpy

questionable provides a lot of syntax sugar surrounding Option/Result types: https://github.com/codex-storage/questionable

ratel is a framework for embedded programming: https://github.com/PMunch/ratel

cps allows arbitrary procedure rewriting to continuation passing style: https://github.com/nim-works/cps

chronos is an alternative async/await backend: https://github.com/status-im/nim-chronos

zero-functional fixes some inefficiencies when chaining list operations: https://github.com/zero-functional/zero-functional

owlkettle is a declarative macro-oriented library for GTK: https://github.com/can-lehmann/owlkettle

A longer list can be found at https://github.com/ringabout/awesome-nim.

Although for a GUI (if I even made one, rather than just a fixed/hardcoded setup) I'd probably use Owlkettle(though there are some things I don't like about it, see closed issue 16).

A similar library in nim is https://github.com/can-lehmann/owlkettle

There's also Owlkettle that seems a bit easier/cleaner IMO, though when I tried it I had some issues (clunky container workflow, wanting better scaling) and would prefer something similar using Qt.
