Font with Built-In Syntax Highlighting (2024)

I view stuff like this kind of like code that fits into a bootloader or whatever. It’s really more of the technical challenge than to actually solve a problem. The result is much better if you just run a script on your hand-coded file to add syntax highlighting as DOM elements. Still, love seeing stuff like this.
In a similar vein: font with integrated story-telling LLM [1]

For blogs, I like the site to stay static. This is a neat way to keep it that way. Having your generator do it is better in my opinion though.
So script inside web page is bad, but script inside font is good? That's interesting definition of bloat. I'd prefer ordinary webpage using locally installed fonts with explicit JavaScript snippet to highlight keywords.
Unless I missed it, the OP doesn't quote reducing bloat as a motivation- more just working without javascript.
I took it to be along the lines of an "easier to work with" type motivation, rather than reducing package sizes.

Is it really a script though? IIUC it's more like contextual declaration (e.g. of previous char is X, then use style Y), no?

This is interesting.
I have yet to see a good web based text editor with syntax highlighting. They all mess with the native search functionality of the browser. Because they can't just use a textarea for the edit area. With this approach, it would be possible.
I wonder how usable a Python version of this would be?

I slightly expect you to pull a "no true Scotsman" here and suggest it's actually no good because it doesn't really support mobile browsers very well, but Microsoft's Monaco editor that's driven from VS Code is quite good. https://microsoft.github.io/monaco-editor/

It seems to have the same problems all of the web based editors I have seen have. Either they capture ctrl+f and take away the native search experience. Or they have a broken search experience. This one is in the latter category.
When I hit ctrl+f on that page and type "export":
First it says "1 of 4 matches" but nothing is highlighted.
When I hit enter, it says "2 of 4 matches" and again, nothing is highlighted.
When I hit enter again, it says "3 of 4 matches" and the first match is highlighted.
When I hit enter again, it says "4 of 4 matches" and the second match is highlighted.

FYI, IDEs and editors too don't use "textarea". Contenteditable essentially makes the web browser work like editor does.
Contenteditable plus the CSS Custom Highlight API (which highlights ranges instead of elements) might indeed allow for a good solution. But I have not yet seen an editor that does that.
I built a prototype that does work. https://hypervariety.com/ScriptHighlighter/
Hmm, is there a simple way to force chrome to use this for view source and/or Inspect? (didn't see anything in the earlier thread either, but those are the two really obvious places that a font would be a reasonable approach...)

Interesting indeed! This bit feels like a neat bit of hackery to keep in my back pocket for sure.

Has anyone tried this with PowerPoint yet? Our org is very PowerPoint centric and always struggle a bit with the workflow for code.
Copy pasting from IntelliJ does give colours but none of the other niceties such as kerning or litigation. Screenshots are nice visually but a pain to maintain.

This is a curious sort of hazy modern mirror image of the world of Sinclair computers, that embedded their BASIC parsing in the keyboard driver — that is to say, it essentially wasn't possible to type a syntactically incorrect BASIC program.

> it breaks when your code goes to a newline.
there's no way to keep context line to line...
This is a blocker for my applications.

But then why does the color disappear if I disallow scripts on this page? Instead of your font, now it uses Consolas.
Are you using JS to load the font in? (if so... web fonts don't need JS to load =)

Most likely because your JS blocker also blocks custom fonts. It works fine without JS.
It does not: with JS blocked, the stylesheet for the webfont never gets injected. Even though it shouldn't need injecting in the first place.
I'm 100% sure it does. Check again.
Then you need to curl the URL, pipe it to an .html file, and then search the resulting file for "@font-face". The only place that has the @font-face rule for this fancy font is inside <template> syntax, meaning it will do nothing (template content is inert) until JS clones that template into the DOM as active content.
That's for the code-editor webcomponent, the rest of the site doesn't use JS.
Correct. The code editor that has the subscript: "The colors in the HTML snippet above comes from within the font itself, the code is plain text, and requires no JavaScript."
Which doesn't work without JS. So adding the @font-face to the page itself, so that things works even without JS, would be lovely.

I think you're seriously confused or purposefully trolling. That's not the web component I'm talking about, that's just plain html.
Using a variable font with r, g, b axes for each alt would maybe make it possible to change the colors?

The whole post proves the opposite is true!

Perhaps you could add this technology to Z80 sans, to get syntax highlighted Z80 disassembly.

And add Z80 emulator as well. Just in case.
Well someone else mentioned llama.ttf which is a font that embeds an llm, using Harfbuzz's WASM engine.
So, you could absolutely write a WASM Z80 emulator and embed it in a font. Whether or not you could make it do anything useful, or how strong your grip on reality would remain after? I don't know.
But it wasn't like you were doing anything else on the days between Christmas and New Year, right?
