A language grammar question

[P233]

I used a trick way to match Sass functions in a new syntax highlighting package. But there is a little problem.

Code: Select all

<key>function</key>
<dict>
   <key>beginCaptures</key>
   <dict>
      <key>1</key>
      <dict>
         <key>name</key>
         <string>keyword.other.round-brackets.sass</string>
      </dict>
   </dict>
   <key>match</key>
   <string>(?&lt;=[\s|\(])[a-zA-Z0-9_-]+(\()</string>
   <key>name</key>
   <string>support.function.name.sass</string>
</dict>


Left side: TextMate, Right side: Sublime Text

As you can see, the left round bracket can be changed colour in TextMate, but not in Sublime Text.

I surmise that beginCaptures / endCaptures cannot work with match rule (they can work with begin/end rule). Is that a bug? Or I did something wrong?

Thanks
