Hi, Xmonad list. I think Xmonad is one of window managers "extensible" by users, or programmable, offering the API and allowing users to override the core code, or freely define new behaviors, though I haven't tried Xmonad actually yet. I'm a former developer of Sawfish which might be the first of such kind of WMs, using a Lisp dialect. I'm interested in comparing them, and created a wiki page for it: http://sawfish.wikia.com/wiki/Comparison_of_extensible_window_managers There Awesome and StumpWM are also studied. If someone is interested, please improve that article. Feel free to add any subjects. Or if you don't feel like editing wiki, you can comment here, and I'll do the actual edit. Of course I'll be glad to answer any questions about Sawfish. # I envy the fact that Xmonad's web site is so well tidy. I tried a lot # in improving Sawfish manual and wiki, but I felt as if I was trying # to move a mountain. With best regards, Teika (Teika kazura)
