Overview

Variables allow you to use data which is not (yet) defined or reference data which is defined somewhere else.

In Skipper, there are three types of variables:

1. Dynamic Variables are used to reference data in the inventory.
2. Static Variables are built into your binary which uses skipper, hence they are known at compile-time.
3. User-Defined Variables are defined and referenced custom values in the inventory.

Format

The format of variables is ${variable_name}. It can be used in Classes and Targets.

The regex used to match variables is: \$\{((\w*)(\:\w+)*)\}
