https://fasterthanli.me/articles/my-gift-to-the-rust-docs-te... is a better link (the author's article about this rather than the artifact produced)

Completely appalled to learn that docs.rs lets you inject any html/css/js you want into the live site (on pages documenting your crate). I love the flexibility but shudder at the security hole the size of, oh, I don’t know, the Grand Canyon.

It’s not a new discovery, I just didn’t know docs.rs (intentionally) wasn’t blocking this. Cf https://docs.rs/pwnies/0.0.13/pwnies/

(This all makes more sense if you read the blog post instead of the direct arborium link: https://fasterthanli.me/articles/my-gift-to-the-rust-docs-te...)

Daaang! On the one hand, as someone developing a code-example custom element[0] that includes highlighting, this is kind of a "so close, but not quite" situation where I really wish this was something I could use for that, but it's probably too heavy to ship around for something so "simple" (as far as users' default expectation; not implying that highlighting text is simple).

But then, on the other hand, I had given up on a scratch code editor for a game development project I'm working on, and just loosely wrapped up the monaco editor which I'm guessing is going to be pretty bare when I actually get around to trying to code with it, in browser (I'm aware that it is robust, but from what I gather, a lot of its features come from third-party dev as a way to keep the core functionality pure). Given that I want to be able to script in C# (aside from just js/ts), I was sure I was going to have to figure something complicated out.

But, honestly, I think this solves all of my most concerning issues! What a sweet little library!

I'm currently building an online 3D-Editor that supports OpenSCAD and Python as the input language.

The ease of use to highlight static text via Arborium seems nice:

    <script src="arborium.iife.js"></script>
    <pre><code class="language-python">
        def hello(name):
            print("Hello " + name);
    </code></pre>

And how would one add SCAD support?

I've been toying around with tree-sitter and have seen the potential for a proper, non-regex based highlighter. It's really powerful because it actually parses the text into an AST. With the AST it's possible for example to make variables the same colour everywhere. A function passed as a parameter could be highlighted as a function even in the parameter list.

I'm happy to see that tree sitter highlighting on the web is finally a thing. This seems really solid although the bundle size is a lot.

If you haven't tried building a grammar with tree-sitter, I highly recommend you do so. It's incredibly fun once you get into a flow state. The docs call it a zen-like experience, and that's a perfect way to describe it. It's so, so good.

The sponsorships achieved by the author is admirable - they really make a lot of valuable oss.

There's also a pure-Rust implementation of a syntax highlighter, which uses TextMate/SublimeText grammars: https://lib.rs/syntect

Treesitter is fantastic. It has builtin support in nvim, and there are a lot of plugins that make use of it.

My favorite is nvim-treesitter-textobjects which gives you dozens of new targets for vim motions, such as a function call or the condition of a loop.

Tree-sitter:

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited.

This is cool! How does it compares with Shiki or Highlighter.js in terms of performance?

I had to wait for about 10 seconds for it to load on my crappy mobile connection.

They also load 1 mb of fonts. In total, this page is close to 3 mb.

Also, when you select a language, the grammar file gets downloaded twice.

Great project, I really love tree-sitter, recently I added a ini variant config profile support to my app, and just use gemini to write a grammar and combine it with another great project called runestone to support highlight the config profile, the total progress is quite smooth.

Sorry, but I can't understand what this actually is. A library, a stand-alone tool, a Rust crate? What users does it target? Text editors, website creators?

The get started section seems to be broken or missing content.

This is cool, was looking for something similar
