Foldmethod=marker, how to customize?

Question

With foldmethod=marker folded portions appear like this:

+--27 lines: First section
+--16 lines: Second section
etc ...

How can I get rid of the +--XX lines: ?

Answer 1

You can change the text displayed for a fold by defining a custom function that generates the text you want displayed and changing the foldtext option to call your function.

Take a look at jpython_fold.vim for an example of this.
