Google Calendar Command Line Interface ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

gcalcli is a Python application that allows you to access your Google Calendar(s) from a command line. It's easy to get your agenda, search for events, add new events, delete events, edit events, see recently updated events, and even import those annoying ICS/vCal invites from Microsoft Exchange and/or other sources. Additionally, gcalcli can be used as a reminder service and execute any application you want when an event is coming up.

gcalcli uses the Google Calendar API version 3 <https://developers.google.com/google-apps/calendar/>__.

``gcalcli`` provides a series of subcommands with the following functionality:


   list                list available calendars
   edit                edit calendar events
   agenda              get an agenda for a time period
   updates             get updates since a datetime for a time period
   calw                get a week-based agenda in calendar format
   calm                get a month agenda in calendar format
   quick               quick-add an event to a calendar
   add                 add a detailed event to the calendar
   import              import an ics/vcal file to a calendar
   remind              execute command if event occurs within <mins> time

See the manual (``man (1) gcalcli``), or run with ``--help``/``-h`` for detailed usage.

Login Information

OAuth2 is used for authenticating with your Google account. The resulting token is placed in the ~/.gcalcli_oauth file. When you first start gcalcli the authentication process will proceed. Simply follow the instructions.

If desired, you can use your own Calendar API instead of the default API values. *NOTE*: these steps are optional!

-  Go to the `Google developer console <https://console.developers.google.com/>`__
-  Make a new project for gcalcli
-  On the sidebar under APIs & Auth, click APIs
-  Enable the Calendar API
-  On the sidebar click Credentials
-  Create a new Client ID. Set the type to Installed Application and the subtype to Other. You will be asked to fill in some consent form information, but what you put here isn't important. It's just what will show up when gcalcli opens up the OAuth website. Anything optional can safely be left blank.
-  Go back to the credentials page and grab your ID and Secret.
-  If desired, add the client-id and client-secret to your .gcalclirc:



-  Remove your existing OAuth information (typically ~/.gcalcli_oauth).
-  Run gcalcli with any desired argument, making sure the new client-id and client-secret are passed on the command line or placed in your .gcalclirc. The OAuth authorization page should be opened automatically in your default browser.

HTTP Proxy Support

gcalcli will automatically work with an HTTP Proxy simply by setting up some environment variables used by the gdata Python module:


   proxy-username or proxy_username
   proxy-password or proxy_password

Note that these environment variables must be lowercase.

Flag File

``gcalcli`` is able to read default configuration information from a flag file. This file is located, by default, at '~/.gcalclirc'. The flag file takes one command line parameter per line.

In the current version, the flag file only supports the global options (options against the ``gcalcli`` program itself). The plan, longer term, is to support a a configuration formation (probably toml or ini), which will allow for configuration of subcommands (such as ``add``, ``agenda``, ``calw``, etc.)




Note that long options require an equal sign if specifying a parameter. With short options the equal sign is optional.

Configuration Folders

gcalcli is able to store all its necessary information in a specific folder (use the --configFolder option.) Each folder will contain 2 files: oauth and cache. An optional 3rd file, gcalclirc, can be present for specific flags that you only want to apply when using this configuration folder.

Importing VCS/VCAL/ICS Files from Exchange (or other)

Importing events from files is easy with gcalcli. The 'import' command accepts a filename on the command line or can read from standard input. Here is a script that can be used as an attachment handler for Thunderbird or in a mailcap entry with Mutt (or in Mutt you could just use the attachment viewer and pipe command):

.. code:: sh



   $TERMINAL -e bash -c "echo 'Importing invite...' ; \
                         gcalcli --detail-url=short \
                                 --calendar='Eric Davis' \
                                 import -v \"$1\" ; \
                         read -p 'press enter to exit: '"

Note that with Thunderbird you'll have to have the 'Show All Body Parts' extension installed for seeing the calendar attachments when not using 'Lightning'. See this `bug report <https://bugzilla.mozilla.org/show_bug.cgi?id=505024>`__ for more details.

Event Popup Reminders

The 'remind' command for gcalcli is used to execute any command as an event notification. This can be a notify-send or an xmessage-like popup or whatever else you can think of. gcalcli does not contain a daemon so you'll have to use some other tool to ensure gcalcli is run in a timely manner for notifications. Two options are using cron or a loop inside a shell script.


.. code:: sh

   % crontab -l
   */10 * * * * /usr/bin/gcalcli remind

Shell script like your .xinitrc so notifications only occur when you're logged in via X:

.. code:: sh


   [[ -x /usr/bin/dunst ]] && /usr/bin/dunst -config ~/.dunstrc &

   if [ -x /usr/bin/gcalcli ]; then
     while true; do
       /usr/bin/gcalcli --calendar="davis" remind
       sleep 300
     done &

   exec herbstluftwm # :-)

By default gcalcli executes the notify-send command for notifications. Most common Linux desktop enviroments already contain a DBUS notification daemon that supports libnotify so it should automagically just work. If you're like me and use nothing that is common I highly recommend the `dunst <https://github.com/knopwob/dunst>`__ dmenu'ish notification daemon.

Note that each time you run this you will get a reminder if you're still inside the event duration. Also note that due to time slip between machines, gcalcli will give you a ~5 minute margin of error. Plan your cron jobs accordingly.

Agenda On Your Root Desktop

Put your agenda on your desktop using `Conky <https://github.com/brndnmtthws/conky>`__. The '--conky' option causes gcalcli to output Conky color sequences. Note that you need to use the Conky 'execpi' command for the gcalcli output to be parsed for color sequences. Add the following to your .conkyrc:


   ${execpi 300 gcalcli --conky agenda}

To also get a graphical calendar that shows the next three weeks add:


   ${execpi 300 gcalcli --conky calw 3}

You may need to increase the ``text_buffer_size`` in your conkyrc file. Users have reported that the default of 256 bytes is too small for busy calendars.

Additionaly you need to set ``--lineart=unicode`` to output unicode-characters for box drawing. To avoid misaligned borders use a monospace font like 'DejaVu Sans Mono'. On Python2 it might be necessary to set the environment variable ``PYTHONIOENCODING=utf8`` if you are using characters beyond ascii. For example:


   ${font DejaVu Sans Mono:size=9}${execpi 300 export PYTHONIOENCODING=utf8 && gcalcli --conky --lineart=unicode calw 3}

Agenda Integration With tmux

Put your next event in the left of your 'tmux' status line. Add the following to your tmux.conf file:


   set-option -g status-interval 60
   set-option -g status-left "#[fg=blue,bright]#(gcalcli agenda | head -2 | tail -1)#[default]"

Agenda Integration With screen

Put your next event in your 'screen' hardstatus line. First add a cron job that will dump you agenda to a text file:


   % crontab -e

Then add the following line:


   */5 * * * * gcalcli --nocolor --nostarted agenda "`date`" > /tmp/gcalcli_agenda.txt

Next create a simple shell script that will extract the first agenda line. Let's call this script 'screen_agenda':


   head -2 /tmp/gcalcli_agenda.txt | tail -1

Next configure screen's hardstatus line to gather data from a backtick command. Of course your hardstatus line is most likely very different than this (Mine is!):


   backtick 1 60 60 screen_agenda
   hardstatus "[ %1` ]"
