Hi,

I'd like jEdit to be able to filter out regions of the buffer, so that I
don't see them in the text area.
The main purpose of this is for preprocessor conditionals in C/C++. Patterns
like the following are quite popular in C/C++:

#ifdef WIN32
.. do something that works on Windows ...
#else
.. do something that works on other operating systems ...
#endif

If I work on Windows, it would be very helpful for me to see only the 2nd
line above, so that the rest of the text doesn't interfere while reading the
buffer (visually).
I'd like to be able to select a word (like WIN32) and have jEdit hide all
lines that do not exist when this word is not defined for the preprocessor.
This is probably a complex feature, and the main problem is that it can
easily conflict with the folding mode. But for starters, I'd like to see how
this really looks in tools (editors?) that already have such a feature. Does
anyone know of such a tool?
IDEs that I know (like Visual Studio) typically show all the text, but show
the text I want to hide in gray (as an indication that this code doesn't
really exist in the current configuration). I'd like to take this one step
further and completely hide this text.

Other uses of this feature would be similar to the Mylyn plugin in eclipse,
which hides text that has never been visited or is rarely visited.

Thanks,
Shlomy
