Compiling the Stylus code
To create a File Watcher
In the Preferences dialog (⌘,), click File Watchers under Tools. The File Watchers page that opens shows the list of already configured File Watchers.
Click the or press ⌘N and choose the Stylus predefined template from the list.
Compiling the code
When you open a file, AppCode checks whether an applicable file watcher is available in the current project. If such file watcher is configured but disabled, AppCode 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, AppCode 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 ( , ⌘S) or when you move focus from AppCode (upon frame deactivation).
AppCode 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.
Select the color scheme, accept the highlighting settings inherited from defaults or customize them as described in Configuring Colors and Fonts.
