What character is used in Puppet to separate modules and classes in a path notation?

In Puppet, the character used to separate modules and classes in a path notation is the double colon (::). This notation is essential for organizing and referencing classes within modules. For instance, if you have a module named "webserver" and a class within it called "apache," you would refer to that class in Puppet manifests as "webserver::apache." The double colon signifies the namespace structure, helping to avoid conflicts between classes in different modules and allowing for a modular approach to configuration management.

Understanding this notation is crucial because it allows Puppet to manage complex infrastructures efficiently, enabling clear access to classes nested within various modules. The use of other characters, such as the colon alone, hyphen, or forward slash, does not fulfill the same purpose in Puppet's architecture, making them unsuitable for separating modules and classes in this context.
