Utility to help integrate the amazing [Mutt][1]/[NeoMutt][2] with the beautiful calendaring application [Khal][3]

$ gem install vkhal 

Vkhal can both display an ics file in Mutt and import it in Khal.

In order to display the events inside your emails add these two lines in your mailcap

text/calendar; vkhal -s %s; copiousoutput application/ics; vkhal -s %s; copiousoutput 

Then add a macro to import events into Khal:

macro attach K \ "\ "<enter-command>unset wait_key<enter>\ <shell-escape>rm -f /tmp/events.ics<enter>\ <save-entry><kill-line>/tmp/events.ics<enter>\ <shell-escape> vkhal -k /tmp/events.ics<enter>\ "
