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.

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).

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.

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

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:

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.
