File Watchers

Last modified: 02 March 2023

File Watchers allow you to automatically run command-line tools like compilers, formatters, or linters when you change or save a file in the IDE.

File Watchers have two dedicated code inspections:

  • The File Watcher available inspection is run in every file where a predefined File Watcher is applicable. If the project has no relevant File Watcher configured, AppCode suggests to add one.

  • The File Watcher problems inspection is invoked by a running File Watcher and highlights errors specific to it.

You can use one of the available templates or configure a File Watcher from scratch. A configured File Watcher can be saved in your project settings or in the IDE settings and used in different projects.

For information on File Watchers for specific tools, see the corresponding pages:

Note that using some of these tools in AppCode requires that you install plugins on the Preferences | Plugins page as described in Installing plugins from JetBrains repository.
