Contents support a number of templates, which can be used throughout various parts of your content. We'll mention these several times throughout this documentation.

A template has the form {{key}} or sometimes {{key1.key2}}. Different templates are supported, depending on where you are using the template.

The following templates may be used:

• {{user.first_name}} : The user's first name.

Valid Locations

These templates may be used in:

• Step contents, titles, or summaries

• Instruction titles, contents, positive or negative feedback

Use Cases

Personalize the Content

By using User templates in content instructions, you can deliver a personalized learning experience.

Add their name to instruction feedback, explain the breakdown of their email in a regex tutorial, and much more.

Use in Program Tests

Ask the user to output their name, and then use a template as part of a test cases expected output to verify that they did so.

Or use a unit test to call a function like hello with their name to personalize their test results.
