Probably one of 'include' or 'import' does what the OP wants, but the mindset is wrong, and that's likely to lead to difficulty.
For another, well-tested best practices dictate that pretty much all declarations other than node definitions should be in classes, in modules. As such, the 'import' function should be used only for a few very specific purposes -- mostly just to support node declarations being in their own files, outside site.pp. For a third, 'import' doesn't necessarily do exactly what people expect. In particular, people sometimes expect it to function like the C preprocessor's '#include' directive, parsing the imported file in the context in which the 'import' function appears, but that's not how it works. Instead, 'import' causes the specified file to be parsed as a stand-alone manifest. It has its uses, but mostly it's a holdover from ancient days. For a fourth, the main purpose of 'include' is different from that of 'import': 'include' declares that the named class(es) should be applied to the target node. It will cause the manifests containing named classes to be parsed if the class has not yet been defined (and its definition is where the autoloader expects to find it), but that's a side effect. In contrast, causing manifests to be parsed is the whole purpose of 'import'. John John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
