# Lyric Render Section
#
# This section has no configuration, and can be ignored.
#
# This section renders <lyric> tags. It forces a html break on every line,
# and styles the section with a css id.
# this id can either be in the mediawiki css files, or defined by the extension
#

#Instruct mediawiki to call LyricExtension to initialise new extension
$wgExtensionFunctions[] = "LyricExtension";

#Install extension
function LyricExtension()
{
  #install hook on the element <lyric>
  global $wgParser;
  $wgParser->setHook("lyric", "renderLyric");

#render <lyric> text
function renderLyric($input, $argv)
{
  #make new lines in wikitext new lines in html
  $transform=str_replace(array("\r\n", "\r","\n"), "<br/>", trim($input));

  #define css lyric style
  $transform="<div id=\"lyric\">".$transform."</div>";

  #parse embedded wikitext
  global $wgOut;

################################################################################
# CSS Styling Section
#
# This section may require configuration.
#
# This section adds a css style to all pages to style lyric sections
#

# If you wish to manually define the style in the css templates,
# add a "#" at the start of this line:
