[clojure-mail "0.1.6"]

A clojure library for parsing, downloading and reading email from Gmail servers.

Possible uses for this library include machine learning corpus generation and command line mail clients.


This is a complete example showing how to read the subject of your latest Gmail inbox message

(ns myproject.core
  (:require [clojure-mail.core :refer :all]))

(def store (gen-store "" "password"))

(def inbox-messages (inbox store))

;; to convert a javamail message into a clojure message we need to call read-message

(def latest (read-message (first inbox-messages)))

;; Let's read the subject of our lastest inbox message
(:subject latest))

(keys latest)
;; => (:subject :from :date-recieved :to :multipart? :content-type :sender :date-sent :body)


We need to require clojure-mail.core before we begin.

(:require [clojure-mail.core :refer :all]
          [clojure-mail.message :as message])

The first thing we need is a mail store which acts as a gateway to our gmail account. To create store we only need a gmail username and password

(def store (gen-store "" "mypassword"))

Now we can fetch email messages from Gmail easily.

(def my-inbox-messages (take 5 (all-messages store :inbox)))

(def first-message (first my-inbox-messages))

(message/subject first-message) ;; => "Hi! Here are your new links from the weekend"

Note that the messages returned are Java mail message objects.

Reading email messages

(def javamail-message (first inbox-messages))

;; To read the entire message as a clojure map
(def message (read-message javamail-message))

;; There are also individual methods available in the message namespace. I.e to read the subject
;; of a javax.mail message

(message/subject javamail-message)

An email message returned as a Clojure map from read-message looks something like this:

{:subject "Re: Presents for Dale's baby",
 :from "Someone <>",
 :date-recieved "Tue Mar 11 12:54:41 GMT 2014",
 :to (""),
 :multipart? true,
 :content-type "multipart/ALTERNATIVE",
 :sender "Someone <>",
 :date-sent "Tue Mar 11 12:54:36 GMT 2014"
 :body [{:content-type "text/plain" :body "..."}
        {:content-type "text/html"  :body "..."}]}


HTML emails are evil. There is a simple HTML -> Plain text parser provided if you need to do any machine learning type processing on email messages.

(require '[clojure-mail.parser :refer :all])

(html->text "<h1>I HATE HTML EMAILS</h1>")


Reading emails from disk

Clojure mail can be used to parse existing email messages from file. Take a look in test/fixtures to see some example messages. To read one of these messages we can do something like this

(def message (read-mail-from-file "test/clojure_mail/fixtures/25"))

(read-message message)

;; =>
;; {:subject "Request to share ContractsBuilder",
;; :from nil, :date-recieved nil,
;; :to "",
;; :multipart? true,
;; :content-type "multipart/alternative; boundary=90e6ba1efefc44ffe804a5e76c56",
;; :sender nil,
;; :date-sent "Fri Jun 17 13:21:19 BST 2011" ..............
