<div>Can you send me the updated grammar/bundle when finished? :)</div><div><br></div><div><br></div>Here's the answer: <div>(from: <a href="http://blog.macromates.com/2011/format-strings/">http://blog.macromates.com/2011/format-strings/</a>)</div>
<div><br></div><div><span class="Apple-style-span" style="font-family:'Lucida Grande',Verdana,Helvetica,sans-serif;font-size:12px"><h2>The Case for Replacements</h2><p>Another form of Format Strings allows you to change the case of a variable reference. If you combine that with the fact that scope <code style="margin-top:0px">name</code>elements in TextMate 2's Language Grammars are now Format Strings, this allows for nice dynamic scoping tricks.</p>
<p>For example, say we rework Ruby's "here-document" (heredoc) syntax rule to look something like this (simplified) example:</p><pre style="background-color:rgb(226,226,226);border-top-width:1px;border-right-width:1px;border-bottom-width:1px;border-left-width:1px;border-top-style:solid;border-right-style:solid;border-bottom-style:solid;border-left-style:solid;border-top-color:rgb(145,150,153);border-right-color:rgb(145,150,153);border-bottom-color:rgb(145,150,153);border-left-color:rgb(145,150,153);padding-top:10px;padding-right:20px;padding-bottom:10px;padding-left:20px;overflow-x:auto;overflow-y:auto">
begin = '<<-?(\w+)';
name = 'string.unquoted.${1:/downcase}.ruby';
…</pre><p>That would mean that a heredoc definition like this:</p><pre style="background-color:rgb(226,226,226);border-top-width:1px;border-right-width:1px;border-bottom-width:1px;border-left-width:1px;border-top-style:solid;border-right-style:solid;border-bottom-style:solid;border-left-style:solid;border-top-color:rgb(145,150,153);border-right-color:rgb(145,150,153);border-bottom-color:rgb(145,150,153);border-left-color:rgb(145,150,153);padding-top:10px;padding-right:20px;padding-bottom:10px;padding-left:20px;overflow-x:auto;overflow-y:auto">
<<-CSS
body {
margin: 10px auto;
}
CSS</pre><p>would be scoped as <code style="margin-top:0px">meta.here-doc.css.ruby</code>. This allows the injection of the CSS Grammar and automations into the scope <code>meta.here-doc.css</code>. That would mean that you get the proper syntax highlighting of these heredocs and you could trigger CSS Bundle commands while editing them.</p>
<p>As I write this, the ruby grammar still has a dozen rules with a dozen different tokens that include a dozen different languages, so the above is a planned simplification that would allow us to avoid having to upgrade the ruby grammar for new potential here-doc tokens.</p>
<p>The supported case transformations are <code style="margin-top:0px">/upcase</code>, <code>/downcase</code>, and<code>/capitalize</code>. There's also a special <code>/asciify</code> transformation that will transliterate things like "æ" and "ø" into "ae" and "o" respectively as well as remove any remaining non-ASCII characters. The latter is particularly useful when deriving an identifier or label, that needs to be accepted by a language parser, from a heading or comment, which is free-form prose. These transformations can be combined.</p>

I'm updating my Markdown bundle to better handle GitHub-style fenced code blocks like so:<br>
<br>
```ruby<br>
foo = { bar: true }<br>
```<br>
<br>
The grammar is simple enough for one language:<br>
<br>
ruby_block = {<br>
begin = '^```ruby.*$';<br>
end = '^```.*$';<br>
patterns = ( { include = 'source.ruby'; } );<br>
};<br>
<br>
However, I'd like to support any language. I tried the following, but it doesn't appear to work (and I'm not sure why):<br>
<br>
code_block = {<br>
begin = '^```(\w+).*$';<br>
end = '^```.*$';<br>
patterns = ( { include = 'source.\1'; } );<br>
};<br>
<br>
Is something similar possible / supported?<br>
<br>
Thanks!<br>
