Remind Widget

This is my Remind widget it's mainly based on the gmail widget from Gigamo's config.

So first off all we create a bashscript named .todo.sh in your home dir

.todo.sh:

   #!/bin/bash
   #
   REMIND=`remind -q ~/.reminders | wc -l` 
   echo $[($REMIND / 2) -1]

This script looks up for for reminders of today in your .reminders and outputs the number of them.

Now we need to create a widget:

   remindwidget = widget({ type = "textbox", name = "remindwidget", align = "right" })
   remindwidget:buttons({ button({ }, 1, function () wicked.update(remindwidget) end) })
   function readRemind(format)
       local f = io.open("/tmp/remind-temp")
       if f == nil then
           return {"n/a"}
       end
       local n = f:read()
       if n == nil or f == " " or f == "" then
           f:close()
           return {"n/a"}
       end
       return {n}
   end
   wicked.register(remindwidget, readRemind, function (widget, args)
       local reminds = args[1]
       if reminds ~= "n/a" and tonumber(reminds) > 0 then
           return spacer..setFg(beautiful.fg_focus, "Rems:")..spacer..setBgFg(beautiful.bg_focus, beautiful.fg_focus, tostring(reminds))..spacer
       else
           return spacer..setFg(beautiful.fg_focus, "Rems:")..spacer..tostring(reminds)..spacer
       end
   end, 120)

This Widget looks every 2 minutes in /tmp/remind-temp for some new reminders.

Now add this Widget to your Statusbar:

    statusbar[s].widgets = ({
       ....
       remindwidget,
       ...
   })

In the next step we create a functions that executes our little bash scripts an writes the output into /tmp/remind-temp:

   function hookAlmostTwoMinutes()
       os.execute(os.getenv("HOME").."/.todo.sh > /tmp/remind-temp &")
   end

and a hook to execute it nearly every two minutes:

   awful.hooks.timer.register(115, hookAlmostTwoMinutes)
