Gedit syntax-highlighting with gtksourceview for backreferencing sub-patterns?

问题

The following will highlight "timeout" on the second line but will not highlight it ever again. Does gtksourceview support some sort of backreference on the "sub-pattern" that will match all instances throughout the file ?

gtksourceview website manual

/usr/share/gtksourceview-2.0/language-specs/c.lang

<context id="struct" style-ref="struct">
     <match>\bstruct\b\s\w+\s(\w+)</match>
          <include>
               <context sub-pattern="1" style-ref="structname"/>
          </include>
</context>

int ns;
struct timeval timeout;
timeout.tv_sec = 1;
timeout.tv_usec = 0;

setsockopt(ns, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));
setsockopt(ns, SOL_SOCKET, SO_RCVTIMEO, &timeout, sizeof(timeout));

回答1:

I think you can only do stateless highlighting in GtkSourceView. Perhaps you can do something with recursive contexts? Capture everything after the second line in your struct context, then highlight your struct name, plus call the main context recursively. I'm not sure whether this would work though.

Apparently, the requested functionality is not supported at the moment.
