Chapter labels

The chapter-label attribute is only available in the Asciidoctor PDF converter.

When using Asciidoctor PDF and the document type is book, level 1 section titles (==) are automatically labeled with Chapter, then the autogenerated chapter number, followed by the title. For example:

Chapter 1: Title

You can modify the chapter label by defining the chapter-label attribute.

:chapter-label: Peatükk

The chapter-label value should be followed by a space to separate the autogenerated number from the label. To remove the label, unset the attribute (:chapter-label!:).
