Some handy dwm scripts.

Ruby gmail checker /home/marko/bin/gmail_checker.rb, which I run from cron every 5 minutes and redirect the output to /home/marko/tmp/mail. The gmail checker script is adapted from a wmii gmail checker plugin

crontab entry

Battery status checker in Ruby. Adapted for dwm from wmii-ruby standard plugin

/home/marko/bin/batstat.rb (updated to use acpi for wider support)

   1  #!/usr/bin/ruby
   2  fd = IO.popen("/usr/bin/acpi")
   3  acpi_status = fd.readlines.to_s.chomp
   4  fd.close
   5  status = '='
   6  status = '^' if acpi_status =~ /harging/
   7  status = 'v' if acpi_status =~ /ischarging/
   8  percentage = /\d+(?=%)/.match(acpi_status)[0].to_i
   9  if acpi_status =~ /ischarging/ && percentage <= 5
  10    system("echo 'Critical battery' | xmessage -center -buttons quit:0 -default quit -file - &")
  11  elsif acpi_status =~ /ischarging/ && percentage <= 8
  12    system("echo 'Low battery' | xmessage -center -buttons quit:0 -default quit -file - &")
  13  end
  14  puts status + percentage.to_s + "%" + status

Then finally the status bar, which is run from .xinitrc.

/home/marko/bin/status

   1  #!/bin/bash
   2  echo "$(cat ~/tmp/mail) | $(date +"w%U %d.%m.%Y %R") | $(ruby ~/bin/batstat.rb)"

/home/marko/.xinitrc

   1  xscreensaver-command -exit
   2  xscreensaver -no-splash &
   3  while true
   4  do
   5  xsetroot -name "$(status)"
   6    sleep 1m
   7  done &
   8  xrandr --output VGA --mode 1920x1200 --right-of LVDS
   9  #xrandr --output VGA --mode 1920x1080 --left-of LVDS
  10  
  11  exec dwm

Create this into your path, edit the paths in the script, make it executable and start using it. Props to Niklas for sharing this idea!

I created the file as ~/bin/note and created symlinks from it to ~/bin/contact, ~/bin/password and ~/bin/todo.

   1  #!/bin/bash
   2  note=$(basename $0)
   3  tmp_file=/tmp/$(date +%d%m%Y-%T-%N)
   4  note_file=/work/real_work/$note
   5  gvim -f $tmp_file
   6  echo "=== $(date +%d%m%Y-%T) ===" >> $note_file
   7  cat $tmp_file >> $note_file
   8  rm $tmp_file
