           Summary: Merge (some) attributes in arbitrary highlighting
           Product: kate
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: kwrite-devel kde org
        ReportedBy: thomas.friedrichsmeier ruhr-uni-bochum de


Version:            (using KDE Devel)
Installed from:    Compiled sources

With the advent of arbitrary highlighting comes a new sort of problem:

Mulitple "things" may be highlighted at the same time, and those highlighted regions \
may overlap. E.g. highlighting 1 may specify attribute A for a region, and \
highlighting 2 may specify attribute B for the same region.

This is perfectly benign as long as attributes A and B concern different aspects, \
such as a background color in attribute A and a font weight in attribute B. However, \
there is only a limited number of aspects that can be merged this easily. For others, \
conflicts arise.

A prime example would be background colors, which seems a reasonable attribute to use \
for anything that is not directly related to syntax highlighting. Among others, the \
search functionality uses the background color to indicate matches. In RKWard we now \
use background colors to mark up user defined regions. However, when both things are \
set at once, only one background color will be used, and the other background \
attribute will be ignored (and indeed, it would be nice, if the user defined regions \
in RKWard could overlap, and still be discernable).

So - what would be nice - would be basic support for merging such attributes. In the \
example, a basic way to blend the background colors, or perhaps to overlay them \
(provided they are not fully opaque).

While not easy to do, this seems at least possible for background and foreground \
brushes. (Of course for other attributes, such as font-style it's just not possible \
at all). _______________________________________________
