Compiling the Stylus code
To compile your code on the fly, you need to configure the compiler as a PhpStorm File Watcher.
To create a File Watcher
Compiling the code
When you open a file, PhpStorm checks whether an applicable file watcher is available in the current project. If such file watcher is configured but disabled, PhpStorm displays a popup that informs you about the configured file watcher and suggests to enable it.
If an applicable file watcher is configured and enabled in the current project, PhpStorm starts it automatically upon the event specified in the New Watcher dialog.
If the Auto-save edited files to trigger the watcher checkbox is selected, the File Watcher is invoked as soon as any changes are made to the source code.
If the Auto-save edited files to trigger the watcher checkbox is cleared, the File Watcher is started upon save ( , Ctrl+S) or when you move focus from PhpStorm (upon frame deactivation).
PhpStorm creates a separate file with the generated output. The file has the name of the source Stylus file and the extension .css. The location of the generated files is defined in the Output paths to refresh field of the New Watcher dialog. However, in the Project Tree, they are shown under the source file which is now displayed as a node.
Configuring syntax highlighting
You can configure Stylus-aware syntax highlighting according to your preferences and habits.
In the Settings/Preferences dialog (Ctrl+Alt+S), go to .
Select the color scheme, accept the highlighting settings inherited from defaults or customize them as described in Configuring Colors and Fonts.
