Try the attached script. I was written quick and dirty fr a similar
issue on this list. It already queries the font attribute, though this
only works with a patched vim, currently.
To return the Cursor highlight, you can then issue:
:let a=Hi("Cursor")
and have all attributes of Cursor in the variable a. To restore the
attributes simply exe the variable a.
The other functions are there to return all available hi groups
(HiLIst()) and SortLines is a debuging function for me to be able to
compare the output from HiList() with a manual list I created using
redir|hi|redir end
You probably won't need it, but I leave it there anyway.
regards,
Christian
