Also some fixes in the syntax highlighter and the streaming parser to recognize more patterns and make it more reliable.

Fixes by Andrew Stewart and Neil Berkman.

Added a new option `:codefence_renderers` by Neil Berkman to customize codefences (those blocks afer ```) which enables a whole new world for plugins!

I'm introducing a Sponsors section (github.com/leandrocp/md...) so if you or your company has been using MDEx, please consider sponsoring the project to help me ship new features, that would be MUCH appreciated 😀

2) Syntax Highlighter with Light/Dark themes

) Initial support for Phoenix Components

Yep, LiveView and Markdown working together.

MDEx - Fast Markdown for Elixir Fast and Extensible Markdown for Elixir with native Phoenix LiveView HEEx integration.

MDEx v0.11 is out celebrating 500k downloads with a new website mdelixir.dev - thanks y'all for the support!

Some exciting new features in this version. See below 👀

#MyElixirStatus

Spread the word! Btw working on that feature to release in the next few days 👀

Hey Brian, attribution was present until v0.6.x (May/June I believe). I only removed it because I wasn't sure about using DockYard trademarks, but I'd gladly add it back again with your approval.

Soon in MDEx ➡️ Phoenix Components!

Yes, MDEx will support embedding HEEx templates inside Markdown. Components and Elixir empressions.

I'm glad it's useful. Enjoy!

crates.io: Rust Package Registry

All the MDEx.Document handling is done in Elixir including buffering and completing markdown chunks (using nimble_parsec). On the Rust side it "only" does parsing and rendering via crates.io/crates/comrak (an amazing project btw).

mdex/examples/streaming.exs at main · leandrocp/mdex Fast and Extensible Markdown for Elixir. Compliant with CommonMark spec. Formats to HTML, JSON, and XML. Built on top of comrak, ammonia, and autumnus. - leandrocp/mdex

Exactly, it's not event based. MDEx doesn't care how or how often you push chunks into the Document. So you can keep a Document in a LiveView and keep pushing into it and render when needed. There's an example here github.com/leandrocp/md...

It can afford to re-render as many times as needed because it's very efficient, although I'm expecting to gather some feedback and adjust if needed. One of the reasons this is considered experimental yet.

Streamdown A drop-in replacement for react-markdown, designed for AI-powered streaming.

This approach is similar to streamdown.ai but using nimble_parsec. A more optimized approach would require rewriting the parser from scratch like github.com/thetarnav/st... is doing but that's not on my plans.

Fragments are buffered until a render or parser is requested (when `MDEx.to_html` or `Document.run` or others are called). At this moment the buffer tail is completed if needed (**text -> **text**) then appended to the rest of the document and re-rendered (that's where Rustler is called). 1/n

And more detailed in the CHANGELOG at hexdocs.pm/mdex/changel...

4. `MDEx.Pipe` is gone. Now all operations are centralized into `MDEx.Document`. Yes that's a **breaking** change but it's worth it.

Pipelines are as simple as adding steps into the document:

3. The Document struct is now displayed in a tree format for better visualization with each node indexed:

Here's a short demo of Markdown streaming in MDEx 👀

Note it's still experimental and disabled by default.

2. Streaming! Now it does complete and render incomplete chunks of Markdown for you:

Thanks to @jskalc.bsky.social we now support converting Markdown to quilljs.com/docs/delta

Hey @thinkingelixir.com thanks for covering MDEx updates (again)!

Here's the updated link to code block decorators guide hexdocs.pm/mdex/code_bl... - and there's more coming soon!

The difference between `Keyword.get(opts, :foo, :default)` and `opts[:foo] || :default` when opts[:foo] is nil. Not a big deal but easy to miss.

Phoenix #LiveView 1.1 is out now! (Actually already yesterday, but we were only able to release the blog post now) #MyElixirStatus

Forgot to post here so... Hello network! It's time for me to move on and I'm kicking off the search for my next role. Let me know if you're looking for someone who obsessively ships, takes on whatever work has the highest impact, and consistently gets feedback like "you're too impatient".
