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, 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.
Check your OS distribution for packages.

--detail_url [short, and 'add' commands as well
long]
--detail_description_width
--[no]started Show already started events (default = True)

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.
gcalcli will automatically work with an HTTP Proxy simply by setting up some environment variables used by the gdata Python module:
http_proxy
https_proxy
proxy-username or proxy_username
proxy-password or proxy_password
Note that these environment variables must be lowercase.
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.
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 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):
#!/bin/bash
TERMINAL=evilvte
CONFIG=~/.gcalclirc
$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 for more details.
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.
Cron:
% crontab -l
*/10 * * * * /usr/bin/gcalcli remind
Shell script like your .xinitrc so notifications only occur when you're logged in via X:
#!/bin/bash
[[ -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 &
fi
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 dmenu'ish notification daemon.
Put your agenda on your desktop using 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}
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]"
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':
#!/bin/bash
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` ]"
