Code Highlighting

Code highlighting is provided through the higlightjs extension which runs highlight.js at build time in Nashorn. All languages from the highlight.js distribution are supported but only a few of them are enabled by default to improve startup time. This and other settings can be changed in the page or site configuration. These are the defaults:

# Settings for the highlight.js-based syntax highlighter
extension.highlightjs {
  # Preloaded languages. Any language that you want to access via an alias
  # should be listed here.
  preload = [scala, java, json, yaml, sql, ini, diff, bash, xml, markdown]

  # Default language when none is specified. Can be one of the supported languages,
  # an array of languages from which to pick automatically, or null or an empty array
  # for plain text. There are separate defaults for fenced code blocks, indented
  # code blocks and inline code.
  fenced    = ${extension.highlightjs.preload}
  indented  = ${extension.highlightjs.preload}
  inline    = null

  # URIs of CSS files and assorted resources required for the style
  # (relative to webjar:/highlight.js/styles/)
  styleResources = [ github-gist.css ]

  # Language codes that should not be processed by the highlighter
  ignore = []
}

Note: The default theme overrides any background color set by the highlight.js style.
