The listings package does not support YAML out of the box. Does a package exist that extends listings with YAML support? More generally, is there a good listing somewhere of extensions to listings?

The »minted« package is your friend here. It uses Python Pygments as back-end for syntax highlighting. And one of the Pygments lexers is for YAML. An approach how to get a YAML script formatted could look like this.

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{minted}

\begin{document}
  \section{The YAML Language}
  \begin{minted}[
    gobble=4,
    frame=single,
    linenos
  ]{yaml}
    --- !clarkevans.com/^invoice

For details about the package and further options for customization please refer to its manual. The example script is taken from the YAML start page.
