File Watchers
The page is available when the File Watchers plugin is enabled. For more information about configuring File Watchers, see File Watchers. The File Watchers plugin is bundled with PhpStorm and activated by default. If the plugin is disabled, enable it on the Installed tab of the Settings/Preferences | Plugins page, as described in Managing plugins.
A File Watcher is a PhpStorm system that tracks changes to your files and runs a third-party standalone application. PhpStorm provides predefined File Watcher templates for a number of such standard popular third-party tools (compilers, compressors, prettifiers, and others).
You can also configure a custom File Watcher to run any other third-party tool.
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, PhpStorm suggests to add one.
The File Watcher problems inspection is invoked by a running File Watcher and highlights errors specific to it.
The page consists of a list of available File Watchers and a toolbar to manage this list.
For each File Watcher, you can decide if it’s going to be available only in the current project (select Project from the Level list) or for all projects (select Global).
To activate a File Watcher, select the checkbox next to it. When a File Watcher is enabled, it starts automatically as soon as a file of the selected type and in the selected scope is changed or saved, see Configuring advanced options. If an error occurs while a File Watcher is running, the File Watcher is automatically disabled. To restore the status, enable the File Watcher manually.
