mdify
mdify is a tool for previewing Markdown documents in your browser, with a clean,
readable serif stylesheet inspired by long-form readers.

Usage
mdify super_secret.md
A new browser tab opens with the rendered document.
Installing
Requires Ruby 3.0 or newer.
gem install mdify
Emacs
You can hook mdify to the compile-command in Emacs so it runs by pressing a key.
Bind the compile key:
(global-set-key [f5] 'compile)
Then add a hook for Markdown mode:
(add-hook 'markdown-mode-hook
(lambda ()
(set (make-local-variable 'compile-command) (concat "mdify " (buffer-name)))))
Now F5 inside any Markdown document previews it in your browser.
Stylesheet
The styling uses IBM Plex Serif over a warm cream palette. There's no support for custom stylesheets yet; open an issue or PR if you'd like that.
