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

*/5 * * * * ruby "/home/marko/bin/gmail_checker.rb" > /home/marko/tmp/mail


CERTPATH = '/etc/ssl/certs'
def gmail_check(username, password)
  req = Net::HTTP::Get.new '/mail/feed/atom'
  req.basic_auth(username, password)

  http = Net::HTTP.new('mail.google.com', 443)
  http.use_ssl = true
  #http.verify_mode = OpenSSL::SSL::VERIFY_PEER
  http.verify_mode = OpenSSL::SSL::VERIFY_NONE
  http.ca_path = CERTPATH

  res = http.request req

  doc = REXML::Document.new res.body
  entries = doc.root.get_elements('/feed/entry')
  return nil if entries.length == 0
  title = entries[0].elements['title'].text
  email = entries[0].elements['author/email'].text
  name = entries[0].elements['author/name'].text
  [ title, email, name, entries.length ]

require 'net/https'
require 'rexml/document'

require 'timeout'
  timeout(2) do
    username = "myemailaddress@aktagon.com"
    password = "p4ssw0rd"

    first = gmail_check(username, password)
    if first
      title, email, name, count = first
      user, domain = email.split('@')
      puts("(#{count}) #{user}:#{title}")
  rescue Timeout::Error

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)

fd = IO.popen("/usr/bin/acpi")
acpi_status = fd.readlines.to_s.chomp
status = '='
status = '^' if acpi_status =~ /harging/
status = 'v' if acpi_status =~ /ischarging/
percentage = /\d+(?=%)/.match(acpi_status)[0].to_i
if acpi_status =~ /ischarging/ && percentage <= 5
  system("echo 'Critical battery' | xmessage -center -buttons quit:0 -default quit -file - &")
elsif acpi_status =~ /ischarging/ && percentage <= 8
  system("echo 'Low battery' | xmessage -center -buttons quit:0 -default quit -file - &")
puts status + percentage.to_s + "%" + status

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


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