fringe-helper.el contains helper functions for fringe bitmaps.

fringe-helper-define allows you to to define fringe bitmaps using a visual string representation. For example:

  (fringe-helper-define 'test-bitmap '(top repeat)

It contains a few stock fringe bitmaps and helps taking care of creating and inserting them.

This looks extremely useful. Fringes are clearly under-used. Perhaps hideshowvis.el can use it to display +/- markers on foldable regions (more easily)?

See also, rfringe, which allows the use of the fringe for indicating buffer-relative positions. --DinoChiesa, 5 April 2011
