That URL seems wrong. It seems like you meant to quote this one instead (otherwise: Why are you digging out ancient commits?): http://git.naquadah.org/?p=awesome.git;a=commitdiff;h=0c62831eea5e651577928ef8b09c947565eaed7d What this does is best illustrated with an example, I think. Add this to your rc.lua: local f f = function(i) if i > 0 then return f(i-1) end error("foo") end f(4) Before the commit, you would get the following error message from awesome: /home/psychon/.config/awesome/rc.lua:4: foo After the commit, you get this instead: error while running function stack traceback: [C]: in function 'error' /home/psychon/.config/awesome/rc.lua:4: in function </home/psychon/.config/awesome/rc.lua:2> (tail call): ? (tail call): ? (tail call): ? (tail call): ? /home/psychon/.config/awesome/rc.lua:6: in main chunk error: /home/psychon/.config/awesome/rc.lua:4: foo Meh. This is not really a good example due to the tail call. However, as you see this now contains a backtrace. The reason I did this was that someone on IRC had a problem with wibox.widget.textbox. textbox.set_markup() was called with argument nil and it was hard to figure out where this "nil" came from. The traceback would have made this a lot easier.
