Features
Markdown Rendering
Hoedown is used internally to render Markdown into HTML. This makes LazyDown’s live preview both efficient and very configurable. It also supports lots of non-standard syntactic features, including the very widely-used fenced code blocks with language identifiers. You can find all the available configurations in the Preferences.
Additional Rendering Tools
LazyDown provides various tools that add additional processing to the rendered HTML, including:
- TeX-like math syntax, including
$$...$$,\\[...\\],\\(...\\), and (optionally)$...$blocks. - GFM task lists.
- Jekyll front-matter.
… and more.

Contributing to the Language List
LazyDown accepts pull requests on aliases to existing languages, but not new syntax highlighting rules. If you wish to provide additional language definitions and/or themes, please visit Prism’s project page and submit them there. I will include updates from Prism after your pull request is accepted.
Auto-completion
I am spoiled, as a programmer, by some pretty advanced auto-completion various IDEs offer. I implemented LazyDown’s auto-completion to suit my own need. Hope it suits you too—or you can turn it off if you wish to.
