The page is available when the File Watchers plugin is enabled. The plugin is not bundled with RubyMine, but it can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.
RubyMine supports integration with various third-party compilers that run in the background and perform the following:
- Translate Less, Sass, SCSS, and Stylus source code into CSS code.
In RubyMine, these compiler configurations are called File Watchers. For each supported compiler, RubyMine provides a predefined File Watcher template. Predefined File Watcher templates are available at the RubyMine level. To run a compiler against your project files you need to create a project-specific File Watcher based on the relevant template, at least, specify the path to the compiler to use on your machine.
To be applicable, a File Watcher must be enabled by selecting the check box next to it on the File Watchers page of the Settings dialog box, see Enabling and Disabling File Watchers. After that the File Watcher will be invoked automatically upon any changes made to the source code or upon save, depending on whether the Immediate File Synchronization check box is selected or cleared, see New Watcher Dialog.
The output of a File Watcher is stored in a separate file. The predefined templates suggest the type of the file depending on the compiler type. By default the output file is created in the same folder as the input file when the File Watcher is invoked for the first time, whereupon this file is only updated. You can customize all these settings during File Watcher creation.
- The File watcher available inspection is invoked in every file that is recognized as subject for applying a predefined file watcher (Sass, Less, SCSS, or CoffeeScript). If none of the applicable predefined File Watchers is associated with the current project, RubyMine suggests to add one.
- The File watcher problems inspection is invoked by a running File Watcher and highlights errors specific for it.
- A list of File Watchers available in the current project. To activate a File Watcher, select the check box next to it. If an error occurs while a File Watcher is running, the File Watcher is automatically disabled.
- A toolbar to manage this list.
|Click this button to open the Choose template pop-up list and choose the relevant type of File Watcher. After that RubyMine opens the New Watcher dialog box for customizing the predefined File Watcher according to the settings of the current project.|
|Click this button to update the settings of the selected File Watcher in the Edit Watcher dialog box. The update is applied to the current project File Watcher only, it does not affect the predefined RubyMine-level template.|
|Click this button to remove the selected File Watcher. The File Watcher is no longer applied to the files in the current project. Note that this action does not affect the corresponding predefined template which is still available at the RubyMine level.|
