Pretty sure none of the GUI parts are open sourced.

Chess.app is open source! https://opensource.apple.com/source/Chess/Chess-318/

TextEdit, too! You can find it as sample code in the developer documentation.

And text edit is the only app I had that would open a 6gb csv file I had. I don't have sublime text but I wonder if it would do it.

Based on my experience with large JS files.... I doubt it

? I've used Sublime to open ~10GB files. It's often the only thing that'll open them. They pride themselves on that ability (among others).

Yeah, sublime is astonishingly fast. Obviously much better than electron-based editors.

If it’s plain text maybe but I’ve found as soon as a syntax highlighter or any parser has to run on it it locks up.

2-3mb JS files brought it to a crawl, and I didn’t have many plugins btw.

Ah. I see why this style is called Grass.

Interesting, Do you know how to grab a copy?

You can click on the blue arrows here to download tarballs https://opensource.apple.com/release/macos-10126.html

Kudos! I'd love to see the game logic.

The game engine itself is a pretty much off the shelf version of Sjeng: https://www.sjeng.org/indexold.html

That's interesting, given Chess has a near identical UI to the old NeXTSTEP Chess.app, which predates Sjeng!

The initial board perspective is similar, but otherwise, the two apps are quite different (One obvious difference is that NeXTStep Chess.app used a bitmapped board with a fixed perspective).

For comparison, the source of the older Chess is also available, in https://opensource.apple.com/release/mac-os-x-1015.html though some parts might no longer compile.
