Puppet Function: stdlib::str2resource

Defined in:
lib/puppet/functions/stdlib/str2resource.rb
Function type:
Ruby 4.x API

Summary

This converts a string to a puppet resource.

Overview

stdlib::str2resource(String $res_string) ⇒ Any

This attempts to convert a string like ‘File’ into the puppet resource ‘File` as detected by the catalog.

Things like ‘File[/foo, /bar]’ are not supported as a title might contain things like ‘,’ or ‘ ’. There is no clear value seperator to use.

This function can depend on the parse order of your manifests/modules as it inspects the catalog thus far.

Examples:

stdlib::str2resource('File[/foo]') => File[/foo]

Parameters:

  • res_string (String) —

    The string to lookup as a resource

Returns:

  • (Any) —

    Puppet::Resource
