mbox-parser

Pure Clojure implementation of a lazy Mbox parser.

Usage

Utility function to create MimeMessages from sequence of strings representing mail message.

(import javax.mail.Session)
(import javax.internet.MimeMessage)

(defn parse-message
  [los]
  (->> (clojure.string/join "\n" los)
       (mbox-parser.utils/string->stream)
       (MimeMessage. (-> (Properties.) (Session/getInstance)))))

Utility function to parse Mbox returning lazy sequence of MimeMessages.

(import javax.mail.Session)
(import javax.internet.MimeMessage)

(defn mbox->messages
  [path]
  (with-open [rdr (clojure.java.io/reader path)]
    (->> (parse-reader rdr)
         (map parse-message)
         (doall))))

mbox-parser doesn't implement these functions because it doesn't relay on javamail library and doesn't take care of opening resources for reading messages.

Given previous functions mbox-parser can be used like this.

(defn list-of-subjects
    [mbox]
    (->> (mbox->messages mbox)
         (map #(.getSubject %)))
