Ruby Gmail Xoauth

This project is the merging of Daniel Parker's ruby-gmail with Nicolas Fouché's gmail_xoauth

The end result is a streamlined API for accessing gmail via IMAP and SMTP, either through a username/password or OAuth credentials.

Description

A Rubyesque interface to Gmail, with all the tools you'll need. Search, read and send multipart emails; archive, mark as read/unread, delete emails; and manage labels.

Features

• Search emails
• Read emails (handles attachments)
• Emails: Label, archive, delete, mark as read/unread/spam
• Create and delete labels
• Create and send multipart email messages in plaintext and/or html, with inline images and attachments
• Utilizes Gmail's IMAP & SMTP, MIME-type detection and parses and generates MIME properly.

Problems:

• May not correctly read malformed MIME messages. This could possibly be corrected by having IMAP parse the MIME structure.
• Cannot grab the plain or html message without also grabbing attachments. It might be nice to lazy-[down]load attachments.

Example Code:

1) Require gmail

require 'gmail' or 'gmail_xoauth'

2) Start an authenticated gmail session

#    If you pass a block, the session will be passed into the block,
#    and the session will be logged out after the block is executed.
gmail = Gmail.new(username, password)
	  or
gmail = GmailXoauth.new(email, token, token_secret, consumer_key, consumer_secret)
# ...do things...
gmail.logout

Gmail.new(username, password) do |gmail|
  # ...do things...
end
or
GmailXoauth.new(email, token, token_secret, consumer_key, consumer_secret) do |gmail|
  # ...do things...
end

3) Count and gather emails!

# Get counts for messages in the inbox
gmail.inbox.count
gmail.inbox.count(:unread)
gmail.inbox.count(:read)

# Count with some criteria
gmail.inbox.count(:after => Date.parse("2010-02-20"), :before => Date.parse("2010-03-20"))
gmail.inbox.count(:on => Date.parse("2010-04-15"))
gmail.inbox.count(:from => "myfriend@gmail.com")
gmail.inbox.count(:to => "directlytome@gmail.com")

# Combine flags and options
gmail.inbox.count(:unread, :from => "myboss@gmail.com")

# Labels work the same way as inbox
gmail.mailbox('Urgent').count

# Getting messages works the same way as counting: optional flag, and optional arguments
# Remember that every message in a conversation/thread will come as a separate message.
gmail.inbox.emails(:unread, :before => Date.parse("2010-04-20"), :from => "myboss@gmail.com")

# Get messages without marking them as read on the server.
gmail.peek = true
gmail.inbox.emails(:unread, :before => Date.parse("2010-04-20"), :from => "myboss@gmail.com")

4) Work with emails!

# any news older than 4-20, mark as read and archive it...
gmail.inbox.emails(:before => Date.parse("2010-04-20"), :from => "news@nbcnews.com").each do |email|
  email.mark(:read) # can also mark :unread or :spam
  email.archive!
end

# delete emails from X...
gmail.inbox.emails(:from => "x-fiancé@gmail.com").each do |email|
  email.delete!
end

# Save all attachments in the "Faxes" label to a folder
folder = "/where/ever"
gmail.mailbox("Faxes").emails.each do |email|
  if !email.message.attachments.empty?
    email.message.save_attachments_to(folder)
  end
end

# Save just the first attachment from the newest unread email (assuming pdf)
# For #save_to_file:
#   + provide a path - save to attachment filename in path
#   + provide a filename - save to file specified
#   + provide no arguments - save to attachment filename in current directory
email = gmail.inbox.emails(:unread).first
email.attachments[0].save_to_file("/path/to/location")

# Add a label to a message
email.label("Faxes")

# Or "move" the message to a label
email.move_to("Faxes")

5) Create new emails!

Creating emails now uses the amazing Mail rubygem. See its documentation here. Ruby-gmail will automatically configure your Mail emails to be sent via your Gmail account's SMTP, so they will be in your Gmail's "Sent" folder. Also, no need to specify the "From" email either, because ruby-gmail will set it for you.

gmail.deliver do
  to "email@example.com"
  subject "Having fun in Puerto Rico!"
  text_part do
    body "Text of plaintext message."
  end
  html_part do
    body "<p>Text of <em>html</em> message.</p>"
  end
  add_file "/path/to/some_image.jpg"
end
# Or, generate the message first and send it later
email = gmail.generate_message do
  to "email@example.com"
  subject "Having fun in Puerto Rico!"
  body "Spent the day on the road..."
end
email.deliver!
# Or...
gmail.deliver(email)

OAuth

OAuth support is for after a token and key have been obtained for a specific user. Since this is already handled well in the oauth and omniauth gems, it is easier to use those rather than reinvent that functionality for this gem. For eductational purposes here is a simple example of integration with oauth. You will of course need to replace the consumer token and secret with your own, but this will work out of the box. For your own app, there are two ways to get this working:

For testing, you can generate and validate your OAuth tokens thanks to the awesome xoauth.py tool.

$ python xoauth.py --generate_oauth_token --user=myemail@gmail.com

For production use you will want to get a proper consumer token and secret. One can be done via Google Account's Manage Domains feature.

Note: The gem supports 3-legged OAuth, and 2-legged OAuth for Google Apps Business or Education account owners. 2-legged OAuth support was added by Wojciech Kruszewski.
