Integrating SyntaxHighlighter into this blog (line wrapping enabled)

Finally integrated current version of SyntaxHighlighter into this blog.
Had to include following into the head section of the blogger template:


<!-- Include required JS files -->

<!--
At least one brush, here we choose JS. You need to include a brush for every
language you want to highlight

$(function(){

var shLineWrap = function(){

$code = $sh.find('td.code');
// Cycle through lines
$gutter.children('.line').each(function(i){

var height = $codeLine.height()||0;
if ( !height ) {
height = 'auto';
}
else {
height = height += 'px';
}
// Copy height over
$gutterLine.height(height+' !important');
console.debug($gutterLine.height(), height, $gutterLine.text(), $codeLine);
});
});
};

// Line wrap back when syntax highlighter has done it's stuff
var shLineWrapWhenReady = function(){
if ( $('.syntaxhighlighter').length === 0 ) {
setTimeout(shLineWrapWhenReady,800);
}
else {
shLineWrap();
}
};

// Fire
shLineWrapWhenReady();
});

<script type='text/javascript'>
SyntaxHighlighter.defaults['gutter'] = false;
SyntaxHighlighter.config.bloggerMode = true;
SyntaxHighlighter.all();
</script>

Done it with a great help from My Tech Notes and Undume Press.
Had to turn gutter off, cause line wrapping malforms line numbering.
More to do: add visual sign of line wrapping, conditional wrapping, etc.
