Class awful.widget.watch
Watch widget.
Here is an example of simple temperature widget which will update each 15
seconds implemented in two different ways.
The first, simpler one, will just display the return command output
(so output is stripped by shell commands).
In the other example sensors returns to the widget its full output
and it’s trimmed in the widget callback function:
211 mytextclock, 212 wibox.widget.textbox(' | '), 213 -- one way to do that: 214 awful.widget.watch('bash -c "sensors | grep temp1"', 15), 215 -- another way: 216 awful.widget.watch('sensors', 15, function(widget, stdout) 217 for line in stdout:gmatch("[^\r\n]+") do 218 if line:match("temp1") then 219 widget:set_text(line) 220 return 221 end 222 end 223 end), 224 s.mylayoutbox,
