Register Extensions
Register one or more extensions
These extensions are registered per document using a callback that feels like a DSL:
Asciidoctor::Extensions.register do
preprocessor FrontMatterPreprocessor
tree_processor ShellSessionTreeProcessor
postprocessor CopyrightFooterPostprocessor
docinfo_processor TrackingCodeDocinfoProcessor if @document.basebackend? 'html'
block ShoutBlock
block_macro GistBlockMacro if @document.basebackend? 'html'
inline_macro ManInlineMacro
include_processor UriIncludeProcessor
end
Extension classes must be defined outside of the register block. Once an extension class is registered, it is frozen, preventing further modification. If you define an extension class inside the register block, it will result in an error on subsequent invocations. |
You can register more than one processor of each type, though you can only have one processor per custom block or macro. Each registered class is instantiated when the Asciidoctor::Document is created.
