Conky Google Calendar

Part 1 » Conky as a System Monitor
Part 2 » Conky Google Calendar using Gcalcli
Part 3 » Additional References for Conky
This is an extreamly peliminary version for the total re-write of these summary notes! These instructions need to be gone through once more (using a different PC) – to ensure that they are correct, and to provide some example output.


If Needed: Uninstall Previous Version of Gcalcli

DO NOT try the following to install gcalcli – as that version uses an old depreciated API that was finally discontinued!
sudo apt-get install gcalcli

“Google deprecated the old APIs that 2.x relies on a couple years back and EOL'd them effective yesterday. You'll need to upgrade to the 3.x release tree to get it working again.” https://github.com/insanum/gcalcli/issues/153

  • If you have the previous version of gcalcli already installed on your system, do the following to uninstall that:
    sudo apt-get purge gcalcli
    rm ~/.gcalclirc     # the old .config file NOT compatible with new program version


Install & Configure Gcalcli for Conky

  • First, install the needed packages via apt-get:
    sudo apt-get install git python-pip python-gdata python-dateutil python-gflags python-vobject python-parsedatetime python-googleapi
  • Next, use pip to install the gcalcli python application
    git clone https://github.com/insanum/gcalcli.git
    cd gcalcli
    sudo python setup.py install
    pip install vobject parsedatetime
On Ubuntu 14.04 this will result in a broken gcalcli command: (must update python-parsedatetime to fix)
  • The following additional commands provide the work-around for this:
    wget https://launchpad.net/~cjohnston/+archive/ubuntu/ppa/+files/python-parsedatetime_1.2-1~ubuntu14.04.1~ppa1_all.deb
    sudo gdebi python-parsedatetime_1.2-1~ubuntu14.04.1~ppa1_all.deb     # requires having installed gdebi

Reference: http://askubuntu.com/questions/468907/how-to-set-up-gcalcli

  • Finally, create the necessary ~/.gcalcli_oauth file, so gcalcli can assess the desired Google Account Calendar(s)
    • Start by entering the following command into the Terminal
      gcalcli list --noauth_local_webserver

      which will output a message that starts with

      WARNING:root:This function, oauth2client.tools.run(), and the use of the gflags library are deprecated
      and will be removed in a future version of the library.
      Go to the following link in your browser:
    • Next into your web-browser, copy & past the in-terminal (on-screen) url that begins with:
          https://accounts.google.com/o/oauth2/auth?
    • Then copy the result code provided by Google, and past that back into the Terminal. (then hit the Enter key)
    • And finally make the file where the oauth info is stored readable only by this user:
      chmod 700 ~/.gcalcli_oauth    # set permissions so only this user can access this file.
  • Now ensure that all the needed files for Conky itself are are installed
    sudo apt-get install conky-all ttf-dejavu ttf-dejavu-core ttf-dejavu-extra

At the bottom of the conkystart.sh startup script, uncomment the last line (remove the leading #), so the Google Calendar Conky will run when the user logs in.
