[SVN] bundle regexp question

[Chris Thomas]

Some notes from the Ruby implementation (syntax: %q!features stolen  
from perl make me "gag"!).

1. Ruby special-cases () [] <> and {}; might wanna check whether perl  
supports those too.

2. Ruby also highlights the prefix. This is consistent with the  
highlighting of the at-sign at the start of a constant NSString  
(@"Turnips!") in Objective-C. None of this was intentional, though,  
and I don't feel strongly about it. I'll update Ruby, at least, to  
whatever you come up with.

You might try something like:

>
>         {    name = "string.unquoted.qq";
>             begin = "qq(.)";
begin = "(qq)(.)";
>             end = "\\1";
             end = "\\2";
>             swallow = "\\\\.";
beginCaptures = {"keyword.string-prefix"}; // or whatever
>         },
