Of course, this is a bit more complicated as you want to ensure that
it only displays a match if you are actually within a class. My
previous method involved some user intelligence. For instance, if you
are at the top of a Python file, you don't want to search backwards
and find the last class definition in the file, the user calling the
mapping would know this. Also if you are in a global function beneath
a class definition, you wouldn't want that class definition being
displayed as this would be misleading.
This sounded like an interesting challenge to me and I'd never played
with the statusline before so I delved into the help-files and off I
went. This is what I came up with in a few minutes:
function! GetLastClass()
let l:retval = "[No class]"
let l:last_line_declaring_a_class = search('^\s*class', 'bnW')
let l:last_line_starting_with_a_word_other_than_class = search('^\
(\<\)\...@=\(class\)\...@!', 'bnW')
if l:last_line_starting_with_a_word_other_than_class <
l:last_line_declaring_a_class
let l:retval = getline(l:last_line_declaring_a_class)
endif
return l:retval
endfunction
setlocal statusline=[%n]\ %{GetLastClass()}\ %<%f%h%m%r%=%b\ 0x%B\ \
%l,%c%V\ %P
This is in my .vim/ftplugin/python.vim.
There are some obvious shortcomings around nested classes but I shall
leave those as an exercise for the reader. I reckon any Python
developer can write Vimscript.
Here are the relevant help pages, which should explain how this little
lot works.

You're welcome. I hope this satisfies your requirements. If you solve
the problems with nested classes, I would very much like to see the
solution.
