Cook Mode (Screen WakeLock)

Cook Mode (Screen WakeLock) Plugin

A plugin for Obsidian that ensures your screen stays awake while using the app. It leverages the Screen Wake Lock API to prevent your screen from going dark without interaction, making it ideal for long reading, writing or brainstorming sessions, or for using Obsidian as a cook book.

Features

• Keeps the display awake while Obsidian is in the foreground.
• Simple and lightweight implementation with minimal impact on performance.
• Multiple activation strategies:
  • Always On: Keeps the screen awake as long as Obsidian is open.
  • Frontmatter: Control activation per file.
  • Editor Focus: Activates only when the editor is in focus.
  • Editor Typing: Activates after five seconds of inactivity (while in the editor).
• Customizable settings:
  • Enable or disable the plugin with a toggle.
  • Choose your preferred activation strategy.
  • Show or hide the WakeLock status in the status bar.
  • Enable or disable notifications for WakeLock events.
  • Developer mode for debugging.
• Cross-platform support: Works on desktop and mobile platforms (with some limitations on iOS).
• Hotkey and command palette integration for quick toggling.
• Status bar integration: Displays the current WakeLock state.

Usage

Once the plugin is enabled, it will automatically keep your screen awake whenever Obsidian is in the foreground. A successful wake lock is indicated by a "Cook Mode on." notification.

You can toggle the functionality through:

• Hotkeys (configurable in Obsidian settings).
• The command palette (Toggle Cook Mode).
• The status bar icon (if enabled).

Activation Strategies

• Always On: Keeps the screen awake as long as Obsidian is open.
• Frontmatter: Use cook-mode: true in the frontmatter definition to keep the screen awake while the file is active.
• Editor Focus: Activates only when the editor is in focus.
• Editor Typing: Activates after five seconds of inactivity (while in the editor).

General rule: The wake lock will release when entering the settings window and reapplied when the settings are exited.

Compatibility

See: Browser Compatibility for the Wake Lock API.

iOS Limitations

Due to partial compatibility, the plugin may not work flawlessly on iOS devices. If the wake lock does not activate when starting the app, try disabling and re-enabling the plugin one or two times. Once it works, it will continue to function until the app is restarted. For convenience, consider creating a keyboard shortcut or configuring your mobile toolbar.

[!NOTE] For devices running iOS 18.4 and later, this is no longer true.
