[TxMt] Pattern priority

[Pedro Melo]

Hi,

I'm writing a small bundle for a HTML template language I use, Tenjin
(http://www.kuwata-lab.com/tenjin/). So far so good but I ran into a
problem with pattern priority in the language definition.

The relevant part of the grammar is this:

	patterns = (
		{	include = 'text.html.basic'; },
		{	name = 'source.perl.pltenjin.expression';
			begin = '(\[==?)';
			end = '(=?=\])';
			captures = {
				1 = { name = 'keyword.control'; };
				2 = { name = 'keyword.control'; };
			};
			patterns = ( { include = 'source.perl'; } );
		}
        );

I "extend" the text.html.basic language (because most of the file is
HTML) and add Tenjin expression. They are in the format [==? =?=] (the
second = means "raw" output, single = means HTML encoded).

TextMate recognizes perfectly my expressions in the text between tags:

<p>[= $var =]</p>   # this is ok

but not when used as a tag attribute value:

<p class="[= $class =]">text</p>   # not ok

In the second case, the [= $class =] text is all green, the context is
string.quoted.double.html and not the expected
source.perl.pltenjin.expression.

Is there any way to work around this?

Thanks,
