Line wrap toggle plugin for Joplin

A Joplin plugin that provides simple control over line wrapping behavior in markdown editors and the note viewer. You will probably want it if you use Joplin for code snippets, markdown tables, ASCII diagrams, long lines, or just prefer horizontal scrolling.

Features

• Toggle line wrap on/off with a single click
• Toolbar button for quick access (optional):
• Tools menu integration
• The plugin does not modify note content - all styling is applied externally
• Separate control for markdown editor and viewer
• State persists across Joplin sessions
• Compatible with CodeMirror 6
• Cross-platform support (Desktop and Mobile)

Limitations

• Toolbar button visibility changes require a Joplin restart to take effect
• Rich text editor is not currently supported

Compatibility

• Joplin Version: 3.2 or later
• CodeMirror: Version 6 (default since Joplin 3.2)
• Platforms: Desktop (Windows, macOS, Linux), Android, iOS

Version history

• 0.2 (23/01/2025)

  • Added padding at the end of the text for the editor
  • Added padding at the end of the text for the viewer

• 0.1 (16/01/2025)

  • Initial release

How It Works

The plugin integrates with Joplin's CodeMirror 6 editor and uses message-based notifications to stay in sync with your settings. Each content script requests the initial configuration, then waits for changes.

When line wrap is disabled, horizontal scrollbars are automatically enabled to allow viewing long lines.

When line wrap is enabled, Joplin will behave exactly as if the plugin was never installed. It does nothing to the default line wrap mechanism.

This plugin does not modify color schemes, fonts or any other visual styles.
