3.2. Creating a new language specification

Follow this quick start guide to create a new Spoofax language specification project to define your own language.

  1. Choose Create New Project from the welcome dialog, or the FileNewProject... menu item, to open the New Project dialog.

  2. Select the Spoofax Language project type.

  3. Select the Metaborg SDK as the project’s SDK.

    Select the "Metaborg SDK"

    Note

    If the Project SDK displays <None> and you can’t select the Metaborg SDK, then you need to add it first.

    1. Click the New... button next to the Project SDK field.
