Creating Scala Worksheet

1. Right-click on your project and select New|Scala Worksheet.

   

   It is recommended to create your worksheet in src directory to simplify an inclusion of the project's classes in the classpath. That might be helpful for testing purposes.

2. In the New Scala Worksheet window type a name of your Scala worksheet and click OK.

   As a result, a file with .sc extension opens. Now you can enter your code.

   

Running Scala Worksheet

1. Enter your code and press to see the results. If you select Interactive Mode check box then the code results will be displayed automatically.

   You can clear the Make project check box to improve evaluation performance. In this case, the automatic checking of project's changes is disabled. The results appear in the view on the right side of your code.

2. You can evaluate a Scala object.

   

   You can fold the output without affecting your code on the left side and expand only that block output that matches a specific statement.

Copying Actions

• Copy your code and evaluation results into one file by clicking icon.

  

Configuring Worksheet Settings

1. Select File|Settings|Languages and Frameworks|Scala and click Worksheet tab.
