Multi-level Nested Syntax Highlighting - TextMate

31 Aug 2021


      Hello
I’ve been using textmate for a while and love it. Ran into a snag today. When I have multi-level nested code, I don't get syntax highlighting.
I’m writing a PHP WordPress function that dynamically builds JSON-LD in a <script> tag and then adds that code to <head> using the wp_head hook. The problem is that JSON-LD and PHP code is not being syntax highlighted when it’s nested like this. It just shows up as a single color (white in my case).
Here’s a truncated example of the code:
<?php
add_action('wp_head', ‘works_jsonld_header');
function works_jsonld_header() {
    ***variables are being set here***
    if (is_singular()){
    ?>
    <script type="application/ld+json”>
    	{
    		"@context": "https://schema.org%E2%80%9D,
    		"@type": "CreativeWork”, 
    		"@id": "<?= $works_link ?>”, 
    		"name": "<?= $w_title ?>”, 
    		"about": "<?= $w_descript ?>”, 
    		"accessMode": ["auditory", "textual", "visual”],
    		"creator": { 
    			"@type": "Person”, 
    			"name": "<?= $short_name ?>”, 
    			"image": "<?= $auth_img_url[0] ?>”, 
    			"sameAs": [ 
    				"<?php echo $auth_link . '"’; 
    				if (isset($auth_wiki_p) && $auth_wiki_p !== '' && isset($auth_wiki_s) && $auth_wiki_s !== ''){ 
    					echo '"' . $auth_wiki_p . '",’; 
    				} else if (isset($auth_wiki_p) && ($auth_wiki_p !== '') && $auth_wiki_s == ''){ 
    					echo '"' . $auth_wiki_p . '"’; 
    				} 
    				if (isset($auth_wiki_s) && $auth_wiki_s !== ''){ 
    					echo '"' . $auth_wiki_s . '"’; 
    				} 
    				?> 
    			]
    		},
    		*** extra code here***
    	}
    </script>
    <?php
    }
}
?>
As you can see, this is PHP nested in JSON-LD, that is nested in HTML, that is nested in PHP :) Code works, but there is no syntax highlighting for JSON-LD or PHP within JSON-LD.
Not sure if there is a way to enable this in TextMate or if it would have to be added as a new feature. Since using schema is quickly becoming a standard, and WordPress powers so many sites, I think it would be very useful if this worked.
Thanks
