Powerline is an awesome little enhancement for Emacs, by an original author unknown, you can find the original version at http://emacswiki.org/emacs/powerline.el
I've added a few different xpm shapes as alternatives to the arrows or flatshapes, a rounded or folded corner, and a set of diagonals.
Grab the updated powerline from here: https://gist.github.com/2945235
Put it somewhere in your Emacs load path (e.g. ~/.emacs.d) and add
the following lines to the end of your .emacs / init.el - to load
it, set the colors and graphic shape:
(require 'powerline)
;; colors...
(setq powerline-color1 "#222") ;; dark grey;
(setq powerline-color2 "#444") ;; slightly lighter grey
;; shape...
(setq powerline-arrow-shape 'arrow) ;; mirrored arrows,
;; see below for the shape options
Shapes
(setq powerline-arrow-shape 'arrow) ;; 18px high arrows
(setq powerline-arrow-shape 'arrow14) ;; 14px high arrows
(setq powerline-arrow-shape 'half) ;; flat
(setq powerline-arrow-shape 'percent) ;; ...? (I have no idea)
(setq powerline-arrow-shape 'curve) ;; scallop curve
New shapes in this version
(setq powerline-arrow-shape 'rounded) ;; new, round corner
(setq powerline-arrow-shape 'chamfer) ;; new, folded corner
(setq powerline-arrow-shape 'slant-left) ;; new, diagonal from left
(setq powerline-arrow-shape 'slant-right) ;; new, diagonal from right
(setq powerline-arrow-shape 'slant) ;; mirrored diagonals
