Making progress in implementing a full terminal UI with a SwiftUI like syntax and easy bindings (no dependency properties!). It supports console resize, mouse, hover, tab, focus, clipboard copy/paste and more! ๐Ÿš€

Still a long way to go but it is already very cool! โœจ

Heya! I just released XenoAtom.Terminal github.com/XenoAtom/XenoAtom.T, a modern replacement for System.Console for .NET CLI/TUI apps. ๐ŸŽ‰

It keeps a familiar Console-like feel, but adds the terminal-native stuff System.Console doesn't cover well: ANSI/VT styling + markup, unified async input events (keys/resize/mouse/paste), restore-on-dispose scopes (raw/cbreak, alternate screen, hide cursorโ€ฆ), clipboard, a rich ReadLine editor, & testable backends, built on top of XenoAtom.Ansi โœจ

A modern .NET replacement for System.Console. Contribute to XenoAtom/XenoAtom.Terminal development by creating an account on GitHub.

This is an unexpected bug in my code. I didn't realize that C#'s nullish operator isn't a null chaining operator.

In JavaScript, this code is correct:

(colorChip?.ranks.Length ?? 0)

In C# it's wrong, since it evaluates to

((colorChip?.ranks).Length ?? 0)

Instead of nulling out the whole chain. Thus here, if `colorChip` is null, I get a null pointer error.

I can't understand why C# uses this approach. I don't see a situation in which it's beneficial.

Hey Mastodon! Here's a very late .

I'm Josh - a software engineer and senior architect working in the more "traditional" finance industry (meaning *not crypto*).

I've shipped code in , , , , , and , but these days I mostly spend my time helping other folks get stuff shipped.

I play games, read a lot, and occasionally write and release half-baked open-source software. I am deeply jealous of people who can draw or paint.
