The Cron plugin for Obsidian allows users to automate tasks by scheduling commands or custom scripts to run at specified times using cron syntax. This plugin supports configurable jobs with options to enable mobile execution, sync checks, and lock toggling to manage job execution and conflicts. It integrates with Obsidian Sync to ensure tasks run only after synchronization is complete across devices. Developers can also use the exposed API to add and manage custom functions, providing flexibility for advanced automation workflows. The plugin helps streamline repetitive tasks, enhancing productivity in Obsidian.
