FluxMarkdown
Press Space on a .md file and get rendered Markdown, with diagrams and maths.
What it does
FluxMarkdown is a Quick Look extension: selecting a Markdown file in Finder and pressing Space renders it rather than showing raw text. It handles GitHub-flavoured Markdown, code blocks with syntax highlighting, Mermaid diagrams and LaTeX maths.
For a machine whose content directory is entirely Markdown, that turns Finder into a usable way to skim what a file says without opening an editor.
Notes
- Available from the developer’s own tap (
xykong/tap), not homebrew-cask. - The extension has to be enabled once in System Settings → Login Items & Extensions → Quick Look.
- It renders the file as written. Hugo shortcodes like
{{< cards >}}will appear as literal text, because nothing outside Hugo knows what they mean.
