OK.... The first is done.

Thanks to Don Cragun for this idea!

You can now click on a code tag area and it will toggle back and forth between the original and the new style, now only plain (no coloring) but it's a start. It works on both mobile and on the desktop, but mobile default to the new code highlighter and the desktop defaults to the original code tags;


Code:
<script language="javascript" type="text/javascript">
function switchCodeTags(codeTag) {
    var eleA = codeTag +"a";
    var eleB = codeTag +"b";
    var x = document.getElementById(eleA);
    var y = document.getElementById(eleB);
    if (x.style.display === "none") {
        y.style.display = "none";
        x.style.display = "block";
        
    } else {
        x.style.display = "none";
        y.style.display = "block";
    }
}
</script>


Here is the core PHP code I changed in class_bbcode.php

Code:
if ($this->printable)
                {
                        $code = $this->emulate_pre_tag($code);
                        $template = 'bbcode_code_printable';
                }
                else
                {
                        $blockheight = $this->fetch_block_height($code);
                        $template = 'bbcode_code';
                        $template_neo = 'bbcode_code_neo';
                }
                eval('$html = "' . fetch_template($template, 0, true, true) . '";');
                eval('$html_neo = "' . fetch_template($template_neo, 0, true, true) .'";');
                 $codeRand = (int)$post['postid']+mt_rand();
                 $tagid137 = "neocodetagid137".$codeRand;
                 $tagid137a = "neocodetagid137".$codeRand.'a';
                 $tagid38a = "neocodetagid38".$codeRand.'a';
                 $tagid38 = "neocodetagid38".$codeRand;
                 $tagid137b = "neocodetagid137".$codeRand.'b';
                 $tagid38b = "neocodetagid38".$codeRand.'b';
              //error_log($tagid137a."\n\n", 3, '/tmp/bbcodelog.log');
               if($vbulletin->userinfo['styleid'] == '137')
                {
                $out = '<div style="display:none;" onclick="switchCodeTags(\''.$tagid137.'\')" id="'.$tagid137b.'">'.$html."</div>";
                $out .= '<div onclick="switchCodeTags(\''.$tagid137.'\')" id="'.$tagid137a.'">'.$html_neo."</div>";
                }
               else
               {
                $out = '<div onclick="switchCodeTags(\''.$tagid38.'\')" id="'.$tagid38b.'">'.$html."</div>";
                $out .= '<div  style="display:none;" onclick="switchCodeTags(\''.$tagid38.'\')" id="'.$tagid38a.'">'.$html_neo."</div>";
               }
                return $out;

Right now it only works for our generic code tags:
Code:
 [CODE][/CODE]

But it is a start ...

Please note when you edit a post you will have to refresh the page if you want the toggle'ing to work. I will fix this small bug later.
