How to center align literals compartment title in Enum class diagram?

Question

I want to create a class diagram of an Enum in PlantUML with the literals keyword centered above the third compartment according to the following quote (also referenced in this answer):

UML 2.5.1 - page 168

A list of EnumerationLiterals may be placed, one to a line, in a compartment named “literals” below the operations compartment. The attributes and operations compartments may be suppressed, and typically are suppressed and empty.

Using the following PlantUML how can I get the literals text to be center alligned?

@startuml

package MyPackage {

enum MyEnum {
attrib1: str
attrib2: int
--
func1()
func2()
--
literals
ONE_LITERAL
TWO_LITERAL
}
}

Answer 1

The easiest way to go is described in plantuml's documentation, in the section "Advanced class body", using a -- separator with title. Your example would look like:

@startuml

package MyPackage {

  enum MyEnum {
    attrib1: str
    attrib2: int
    --
    func1()
    func2()
    -- literals --
    ONE_LITERAL
    TWO_LITERAL
  }
}

and result in:
