MMD-QuickLook

MMD‑QuickLook is a macOS Quick Look plugin that renders MultiMarkdown files directly in the Finder preview pane. When a file with an .md or .markdown extension is selected, the plugin generates an HTML preview styled with a default GitHub‑based stylesheet, allowing users to see formatted headings, tables, code blocks, and other MultiMarkdown elements without opening an external editor.

The plugin supports customization through a `.mdqlstyle.css` file placed in the user’s home directory; any valid CSS can be supplied to alter colors, fonts, or layout, and a few ready‑made styles are included. It also handles advanced MultiMarkdown features such as table of contents placeholders (`{{TOC}}`), metadata references, and TextBundle bundles, ensuring that more complex documents are displayed accurately.

Installation can be performed via Homebrew cask or by manually copying the generator into `~/Library/QuickLook/` and reloading Quick Look with `qlmanage -r`. The project is maintained as a stable macOS core component.
