How do I add another tag to be parsed as embedded JS in a tmLanguage file?

Question

Back Story (not really important but it frames the question)

I have a TagLib in a JSP that takes its contents and wraps its containing code in a script block (it does much more but for the sake of the question it is not important). For example:

<aui:script use="some-module">
    //my code
</aui:script>

will be served as

<script type="text/javascript>
    AUI().use('sub-module', function(A) {
        // my code
    }
</script>

The Question

I would like all the code in between <aui:script use="things"></aui:script> and to have JavaScript syntax highlighting. So I tried editing the HTML.tmLanguage file to include this but Sublime Text 2 throws a fit.

Admittedly my regex knowledge is poor.

How can I edit HTML.tmLanguage to include my <aui:script /> taglib?

Site note, the taglib accepts various attributes like use and position.

Answer 1

I have so much trouble with the regex rules but I managed to get it somewhat working using the normal rules. I should add that this is a new block, along with the regular one.

{
    name = 'source.js.embedded.html';
    begin = '(?:^\s+)?(<)((?i:(aui[\:]script)))\b(?![^>]*/>)';
    end = '(?<=</(aui[\:]script))(>)(?:\s*\n)?';
    beginCaptures = {
        1 = { name = 'punctuation.definition.tag.html'; };
        2 = { name = 'entity.name.tag.script.html'; };
    };
    endCaptures = {
        2 = {
            name = 'punctuation.definition.tag.html';
        };
    };
    patterns = (
        {
            include = '#tag-stuff';
        },
        {
            begin = '(?<!</(?:aui[\:]script))(>)';
            end = '(</)((?i:aui[\:]script))';
            captures = {
                1 = {
                    name = 'punctuation.definition.tag.html';
                };
                2 = {
                    name = 'entity.name.tag.script.html';
                };
            };
            patterns = (
                {   name = 'comment.line.double-slash.js';
                    match = '(//).*?((?=</(aui[\:]script))|$\n?)';
                    captures = {
                        1 = {
                            name = 'punctuation.definition.comment.js';
                        };
                    };
                },
                {
                    name = 'comment.block.js';
                    begin = '/\*';
                    end = '\*/|(?=</(aui[\:]script))';
                    captures = {
                        0 = {
                            name = 'punctuation.definition.comment.js';
                        };
                    };
                },
                {
                    include = '#php';
                },
                {
                    include = 'source.js';
                },
            );
        },
    );
}
