[TxMt] Use begin marker of a scope to end the previous one

[Pierre Morel]

Hello,

I'm trying to enhance the Matlab bundle. Especially by trying to make  
matlab and texmate to interact (shortcut to launch a script etc...).  
And I must say I'm pretty bad with shell scripts and regular  
expressions.

I've nevertheless managed to do that, and now I'm trying to recreate  
matlab "cell mode" : matlab source files are scripts, and it is  
possible to divide the script in "cells". When you are in the (awful)  
matlab editor, you can run the current cell just with cmd+enter. This  
is very useful. The problem is that the cell separator is just a line  
like this :

%% Title of the new cell

...That's it, there is no ending marker for a cell : the current cell  
ends where the new one starts ! What I've done now is creating a new  
"cell" scope delimited by these lines, but as soon as one "%% ...."  
line is used to mark the end of a scope, it can't be used to start the  
following one.

Here's my descriptor.

			contentName = 'meta.cell.matlab';
			begin = '%%.*$\n';
			end = '%%.*$\n';
			captures = { 0 = { name = 'meta.celltitle.matlab'; }; };
			patterns = (
				# Here I include all the other scope descriptors, because they can  
be contained in a cell !
			)

For my solution to work, I then have to use two of these "%% ..."  
lines, one to end the previous cell scope, and one to start the new  
one. This means matlab files need to be modified to work, which is not  
so good !

Do you have an idea on how to solve this problem ?
A linked problem (but less important) is that I can't get code folding  
to work with cells : a start marker can't be the same as an end marker.


Thank you !
