Project mention: Brush (Bo(u)rn(e) RUsty SHell) a POSIX and Bash-Compatible Shell in Rust | news.ycombinator.com | 2025-05-06
"can" is doing some heavy lifting there, especially based on my experience with VSCodium (which by definition is forced to work within Microsoft's opinion of build systems)
Anyway, uh-huh:

As a frame of reference, to build bash one only needs /bin/sh not a pre-built copy of bash itself https://git.savannah.gnu.org/cgit/bash.git/tree/configure?h=...

Avalonia
Develop Desktop, Embedded, Mobile and WebAssembly apps with C# and XAML. The most popular .NET UI client technology
Check out https://avaloniaui.net as well. It's basically a cross-platform reimplementation of WPF. It's not quite as simple as C#+WinForms or Lazarus+LCL because you don't get drag-and-drop UI designer, and you need to write markup by hand (albeit with live preview). But unlike HTML, it's actually designed for desktop UI apps from the get go, so it's much easier to write for anything non-trivial. And you can still write "quick and dirty" GUI code by directly connecting event handlers to buttons and updating values etc in it, ignoring data bindings and other more advanced facilities.

Uno Platform
Open-source platform for building cross-platform native Mobile, Web, Desktop and Embedded apps quickly. Create rich, C#/XAML, single-codebase apps from any IDE. Hot Reload included! 90m+ NuGet Downloads!!
As-is today, AI tools provide some productivity gains. However, they are not replacements for experienced developers. At Uno Platform we are investing in tools which make developers productive within their current environments, such as Hot Design. Also, we are keeping a close eye and thinking of these useful scenarios to apply AI to, as we don’t believe just adding a simple LLM to it will actually add value. So, stay tuned to our blogs and Dev.to account as there is more goodness coming on this topic.

electrino
Desktop runtime for apps built on web technologies, using the system's own web browser engine
Project mention: Electrobun: Cross-platform desktop applications written in TypeScript | news.ycombinator.com | 2024-11-20So is it a yet another webview-based framework like NeutralinoJS (https://neutralino.js.org), Electrino (https://github.com/pojala/electrino) or DeskGap (https://deskgap.com)? What's their advantage apart from using Bun instead of Node?
For relly lightweight cross-platform desktop apps better use a non-webview-based native framework like Qt, GTK, wxWidgets or even recently released FLTK 1.4.
