Re: syntax parsing of non-contiguous regions

[Alexander Katovsky]

I'm afraid I'm being a little slow understanding you're suggestion.  
I've already defined comment-start and comment-end as '!' and '\n' 
respectively.  Also, I need all the syntax motion functions 
(forward-sexp, parse-partial-sexp et al) to treat the embedded code as a 
comment so that the embedded code does not disrupt syntax motion 
outside.  For example, suppose that my primary mode is for code 
consisting of named blocks with comments starting with '!' and ending 
with newline, and my embedded code is C.  Then we could have

named-block  ! some comment
{
   %{
       if(a != b){}
   }%
}

Then the syntax motion functions would completely ignore the embedded 
code, just as it would a comment.  So if point is before the first 
opening brace then, no matter what's inside %{}%, forward-sexp would 
place point at the last closing brace.  And all the other syntax 
functions would just 'work' as well!

I'd be very grateful if could explain in a little more detail exactly 
what the 'hide-or-ignore' functions that you suggest are and how they 
could be used to achieve this effect.

Thanks,
Alex
