Install

sudo gem install vpim

vPim provides calendaring, scheduling, and contact support for Ruby through the standard iCalendar and vCard data formats for “personal information” exchange.

Thanks

  • ZipDX.com: for sponsoring development of FREQ=weekly and BYSETPOS in recurrence rules.

  • RubyForge.org: for their generous hosting of this project.

Installation

There is a vPim package installable using ruby-gems:

# sudo gem install vpim (may require root privilege)

It is also installable in the standard way. Untar the package, and do:

$ ruby setup.rb --help

or do:

$ ruby setup.rb config
$ ruby setup.rb setup
# ruby setup.rb install (may require root privilege)

Overview

vCard (RFC 2426) is a format for personal information, see Vpim::Vcard and Vpim::Maker::Vcard.

iCalendar (RFC 2445) is a format for calendar related information, see Vpim::Icalendar.

vCard and iCalendar support is built on top of an implementation of the MIME Content-Type for Directory Information (RFC 2425). The basic RFC 2425 format is implemented by Vpim::DirectoryInfo and Vpim::DirectoryInfo::Field.

The libary is quite useful, but improvements are ongoing. If you find something missing or have suggestions, please contact me. I can't promise instantaneous turnaround, but I might be able to suggest another approach, and features requested by users of vPim go to the top of the todo list. If you need a feature for a commercial project, consider sponsoring development.

Examples

Here's an example to give a sense for how iCalendars are encoded and decoded:

require 'vpim/icalendar'

cal = Vpim::Icalendar.create2

cal.add_event do |e|
  e.dtstart       Date.new(2005, 04, 28)
  e.dtend         Date.new(2005, 04, 29)
  e.summary       "Monthly meet-the-CEO day"
  e.description <<'---'
Unlike last one, this meeting will change your life because
we are going to discuss your likely demotion if your work isn't
done soon.
---
  e.categories    [ 'APPOINTMENT' ]
  e.categories do |c| c.push 'EDUCATION' end
  e.url           'http://www.example.com'
  e.sequence      0
  e.access_class  "PRIVATE"
  e.transparency  'OPAQUE'

  now = Time.now
  e.created       now
  e.lastmod       now

  e.organizer do |o|
    o.cn = "Example Organizer, Mr."
    o.uri = "mailto:organizer@example.com"
  end

  attendee = Vpim::Icalendar::Address.create("mailto:attendee@example.com")
  attendee.rsvp = true
  e.add_attendee attendee
end

icsfile = cal.encode

puts '--- Encode:'

puts icsfile

puts '--- Decode:'

cal = Vpim::Icalendar.decode(icsfile).first

cal.components do |e|
  puts e.summary
  puts e.description
  puts e.dtstart.to_s
  puts e.dtend.to_s
end

This produces:

--- Encode:

More examples of using vPim are provided in samples/.

vCard examples are:

iCalendar examples are:

  • ics-to-rss.txt: prints todos as RSS, or starts a WEBrick servlet that publishes todos as a RSS feed. Thanks to Dave Thomas for this idea, from pragprog.com/pragdave/Tech/Blog/ToDos.rdoc.

  • cmd-itip.txt: prints emailed iCalendar invitations in human-readable form, and see README.mutt for instruction on mutt integration. I get a lot of meeting invitations from Lotus Notes/Domino users at work, and this is pretty useful in figuring out where and when I am supposed to be.

  • reminder.txt: prints upcoming events and todos, by default from Apple's iCal calendars

  • rrule.txt: utility for printing recurrence rules

  • ics-dump.txt: utility for dumping contents of .ics files
