3.2.2 Decorators

Decorators are used to add extra information to a block’s #:code field before printing it. Most commonly, this means syntax highlighting.

Decorators are stored in an alist. The key is the output type and the value is the decorator.

(define %default-decorators
`((sxml . ,%no-decoration)))

This means that when printing a code block to SXML, the code is by default wrapped in a %no-decoration call, i.e. (%no-decoration code).

Languages can change how the code is printed to various types by customizing the alist.
