Puppet.Interpreter.Catalog

Description

This module exports the getCatalog function, that computes catalogs from parsed manifests. The behaviour of this module is probably non canonical on many details. The problem is that most of Puppet behaviour is undocumented or extremely vague. It might be possible to delve into the source code or to write tests, but ruby is unreadable and tests are boring.

Here is a list of known discrepencies with Puppet :

  • Variables coming from an inherited class can only be referenced using the scope of the child class.
  • Resources references using the | | syntax are not yet supported.
