MacDown is an open source Markdown editor for OS X. It is heavily influenced by Chen Luo’s Mou.

Why Another Markdown Editor?
I like Mou. I write Markdown all the time, and since I use macOS on a daily basis, Mou is my go-to editor whenever I wish to generate something with markup. But I had always wanted something more.

It came as a great shock when Chen Luo announced that he felt he could not actively continue the development, and wished to sell the ownership of Mou. No suitable offers surfaced (I honestly do not think there will be, either), and I decided that instead of waiting for others to do something about this, I should act myself.

I don’t have nearly enough money to match Chen Luo’s purposed offer, but I do have my own pocket of tricks and some free time. So I started from scratch, spent some weekends hacking together my own solution. And this is the result.

What’s in the Box?
MacDown is heavily influenced by Mou, and I try to mimic much of its behaviour as much as possible both in UI and the logic underneath, only making changes when I feel that improvement is necessary. Highlights include:
• Highly customisable Markdown rendering.
• Syntax highlighting in fenced code blocks.
• Sophisticated auto-completion.

Main Features

Markdown Rendering
Hoedown is used internally to render Markdown into HTML. This makes MacDown’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 MacDown’s Preferences pane.

Additional Rendering Tools
MacDown 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.

Syntax Highlighting
Syntax highlighting in fenced code blocks with language identifiers are rendered by Prism.

Contributing to the Language List
MacDown 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.

I am spoiled, as a programmer, by some pretty advanced auto-completion various IDEs offer. I implemented MacDown’s auto-completion to suit my own need. Hope it suits you too—or you can turn it off if you wish to.
