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, let me know if you need the plugin to work with it.
• iOS is supported but Joplin team must manually approve it to be available in the platform.

Compatibility

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

• 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
  • Tested on Joplin Desktop 3.5.12, 3.6.2 and Android 3.5.9

• 0.1 (16/01/2025)

  • Initial release

How It Works

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 or contents of the notes. It acts only on the viewer and editor panels.
