QLCommonMark

This Quick Look generator renders CommonMark and Markdown files directly in macOS Finder previews. It parses the source text with the cmark library and applies Bootstrap styling to produce a formatted HTML preview that appears when a file is selected. The plugin is distributed as a .qlgenerator bundle that can be placed in the user or system QuickLook directories, and it can be refreshed with the `qlmanage -r` command if needed.

Installation is straightforward: download the bundle from the project’s releases page and copy it into `~/Library/QuickLook` or `/Library/QuickLook`, or use Homebrew‑Cask with `brew cask install qlcommonmark`. The package is marked as stable and is intended for macOS environments.

The tool is useful for developers, writers, and anyone who works with Markdown or CommonMark documents and wants instant visual feedback without opening a separate editor. It builds on prior Quick Look solutions for Markdown and integrates with the Versatil Markdown editor, which includes QLCommonMark as its preview component.
