module Puppet::Parser::Files

Find the path to the given file selector. Files can be selected in one of two ways:

* absolute path: the path is simply returned
* modulename/filename selector: a file is found in the file directory
  of the named module.

In the second case a nil is returned if there isn't a file found. In the first case (absolute path), there is no existence check done and so the path will be returned even if there isn't a file available.

@param template [String] the file selector @param environment [Puppet::Node::Environment] the environment in which to search @return [String, nil] the absolute path to the file or nil if there is no file found

@api private

   # File lib/puppet/parser/files.rb
41 def find_file(file, environment)
42   find_in_module(file, environment) do |mod,module_file|
43     mod.file(module_file)
44   end
45 end

@api private

   # File lib/puppet/parser/files.rb
69 def find_in_module(reference, environment)
70   if Puppet::Util.absolute_path?(reference)
71     reference
72   else
73     path, file = split_file_path(reference)
74     mod = environment.module(path)
75 
76     if file && mod
77       yield(mod, file)
78     else
79       nil
80     end
81   end
82 end

Return a list of manifests as absolute filenames matching the given pattern.

@param pattern [String] A reference for a file in a module. It is the

format "<modulename>/<file glob>"

@param environment [Puppet::Node::Environment] the environment of modules

@return [Array(String, Array<String>)] the module name and the list of files found @api private

   # File lib/puppet/parser/files.rb
15 def find_manifests_in_modules(pattern, environment)
16   module_name, file_pattern = split_file_path(pattern)
17 
18   mod = environment.module(module_name)
19   if mod
20     [mod.name, mod.match_manifests(file_pattern)]
21   else
22     [nil, []]
23   end
24 end

Find the path to the given template selector. Templates can be selected in a couple of ways:

* absolute path: the path is simply returned
* modulename/filename selector: a file is found in the template directory
  of the named module.

In the last two cases a nil is returned if there isn't a file found. In the first case (absolute path), there is no existence check done and so the path will be returned even if there isn't a file available.

@param template [String] the template selector @param environment [Puppet::Node::Environment] the environment in which to search @return [String, nil] the absolute path to the template file or nil if there is no file found

@api private

   # File lib/puppet/parser/files.rb
62 def find_template(template, environment)
63   find_in_module(template, environment) do |mod,template_file|
64     mod.template(template_file)
65   end
66 end

Split the path into the module and the rest of the path, or return nil if the path is empty or absolute (starts with a /). @api private

   # File lib/puppet/parser/files.rb
87 def split_file_path(path)
88   if path == "" || Puppet::Util.absolute_path?(path)
89     nil
90   else
91     path.split(File::SEPARATOR, 2)
92   end
93 end
