Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

This class provides a data structure representing a module’s metadata.

Constructor Details

#initialize ⇒ Metadata

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Expose any metadata keys as callable reader methods.

Instance Method Details

#add_dependency(name, version_requirement = nil, repository = nil) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Validates the name and version_requirement for a dependency, then creates the Dependency and adds it. Returns the Dependency that was added.

  if dup = @data['dependencies'].find { |d| d.full_module_name == name && d.version_requirement != version_requirement }
    raise ArgumentError, "Dependency conflict for #{full_module_name}: Dependency #{name} was given conflicting version requirements #{version_requirement} and #{dup.version_requirement}. Verify that there are no duplicates in the metadata.json or the Modulefile."
  end

  dep = Dependency.new(name, version_requirement, repository)
  @data['dependencies'].add(dep)

  dep
end

#dashed_name ⇒ Object Also known as: full_module_name

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a filesystem-friendly version of this module name.

#description ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Deprecated.

Provides an accessor for the now defunct ‘description’ property. This addresses a regression in Puppet 3.6.x where previously valid templates refering to the ‘description’ property were broken.

#release_name ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a string that uniquely represents this version of this module.

end

#to_hash ⇒ Object Also known as: to_data_hash

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a hash of the module’s metadata. Used by Puppet’s automated serialization routines.

  end

  "{\n" + contents.join(",\n").gsub(/^/, '  ') + "\n}\n"
end

#update(data, with_dependencies = true) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Merges the current set of metadata with another metadata hash. This method also handles the validation of module names and versions, in an effort to be proactive about module publishing constraints.
