CLion 2019.3 Help

Stylus

CLion lets you translate your Stylus code into CSS on the fly.

Before you start

  1. Make sure you have Node.js on your computer.

  2. Install and enable the File Watchers plugin on the Plugins page as described in Installing plugins from repository.

  3. Make sure the Stylus bundled plugin is enabled on the Plugins page, see Managing plugins for details.

Installing Stylus

  • In the embedded Terminal (Alt+F12), type:

    npm install --global stylus

    Learn more from the Stylus official website.

You can also install the stylus package on the Node.js and NPM page as described in npm and Yarn.

Compiling the Stylus code

To compile your code on the fly, you need to configure the compiler as a CLion File Watcher.

To create a File Watcher

  1. In the Settings/Preferences dialog Ctrl+Alt+S, click File Watchers under Tools. The File Watchers page that opens shows the list of already configured File Watchers.

  2. Click the Add button or press Alt+Insert and choose the Stylus predefined template from the list.

Compiling the code

When you open a file, CLion checks whether an applicable file watcher is available in the current project. If such file watcher is configured but disabled, CLion 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, CLion 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 (File | Save All, Ctrl+S) or when you move focus from CLion (upon frame deactivation).

CLion 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.

  1. In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Color Scheme | Stylus.

  2. Select the color scheme, accept the highlighting settings inherited from defaults or customize them as described in Configuring Colors and Fonts.
