Extension Details

Nova md-fixup provides integration with
md-fixup, a powerful Markdown formatter
by Brett Terpstra that wraps text and ensures proper formatting.

Requirements

Nova md-fixup requires md-fixup to be installed on your Mac:

• md-fixup - Follow the installation
  instructions in the repository

Important: The md-fixup binary needs to be accessible in Nova. There are a
few default locations coded in, and the extension will check Nova's PATH. If the
defaults don't work, the full path can be specified in the extension settings,
e.g., /opt/homebrew/bin/md-fixup or /usr/local/bin/md-fixup (to find the
path to md-fixup , run which md-fixup in a terminal window).

Usage

Nova md-fixup provides two commands:

• Format Document - Format the current Markdown file
• Format Workspace - Format all open Markdown files

To format a document:

• Select Editor → Nova md-fixup → Format Document; or
• Open the command palette and type "Format Document"

You can also enable Format on Save in the extension preferences to
automatically format Markdown files when saving.

Configuration

To configure global preferences, open Extensions → Extension Library... then
select Nova md-fixup's Preferences tab.

You can also configure preferences on a per-project basis in Project → Project
Settings...

Available settings:

• Executable Path - Path to md-fixup (leave empty to use PATH)
• Wrap Width - Text wrap width in characters (default: 60)
• Skip Rules - Comma-separated list of rules to skip (e.g.,
  "wrap,typography")
• Format on Save - Automatically format when saving (default: off)
• Reverse Emphasis - Use ** for bold and _ for italic (default: off)
• Additional Arguments - Custom command-line arguments

md-fixup Rules

md-fixup applies 33 formatting rules including:

• Normalize line endings and whitespace
• Ensure proper spacing around headers, lists, and code blocks
• Wrap text at specified width
• Normalize bold/italic markers
• Fix typography (smart quotes, em dashes, etc.)
• Format tables
• And many more...

See the md-fixup documentation for the
complete list of rules and their keywords. If rules are specified in a user's
global .md-fixup file, they should be used.
