# MarsEdit

MarsEdit stores posts inside its database, not as loose files on disk. Marked therefore uses a dedicated preview workflow that talks to the running MarsEdit application.

## MarsEdit Preview window

Choose File New MarsEdit Preview. Marked asks AppleScript to read the front post in MarsEdit (Red Sweater’s bundle IDs for direct, Mac App Store, Setapp, and MarsEdit 4/5 are recognized). Keep MarsEdit running with a document open while you work.

- Manual refresh: save from Marked’s preview if you want to force an update.
- Automatic updates: enable watching so each MarsEdit autosave refreshes Marked.

If no post is available, Marked surfaces a short error in the preview instead of stale text.

### Extended posts

Content in MarsEdit’s extended field is separated in Marked’s preview and source using a WordPress-style `<!--more-->` divider so pagination-oriented sites (WordPress, Jekyll, etc.) still see the break. The comment is harmless elsewhere.

### Tags and categories in metadata

MarsEdit’s tags and categories are exposed to the MultiMarkdown metadata block. With the MultiMarkdown processor (Marked Settings, Processor pane), you can reference them like:

    Tagged: [%tags]
    Posted In: [%categories]
