Node.js port of Github's EmailReplyParser, a small library to parse plain text email content.

var EmailReplyParser = require('emailreplyparser')

// To parse the reply from an email body
var parsed = EmailReplyParser.parse(emailBody)

// To parse the reply from an email body, preserving signatures
var parsed = EmailReplyParser.parse(emailBody, true)

// Reads in an email and produces an array of fragments.
// Each fragment represents a part of the email.
var fragments = EmailReplyParser.read(emailBody)

For examples, refer to the tests.

(Taken from Github's version)

Quoted headers aren't picked up if there's an extra line break:

On <date>, <author> wrote:

> blah

Also, they're not picked up if the email client breaks it up into multiple lines. GMail breaks up any lines over 80 characters for you.

On <date>, <author>
wrote:
> blah

Not to mention that we're search for "on" and "wrote". It won't work with other languages.

Possible solution: Remove "[email protected]" lines...

Lines starting with - or _ sometimes mark the beginning of signatures:

Hello

--
Rick

Not everyone follows this convention:

Hello

Mr Rick Olson
Galactic President Superstar Mc Awesomeville
GitHub

**********************DISCLAIMER***********************************
* Note: blah blah blah                                            *
**********************DISCLAIMER***********************************

Apparently, prefixing lines with > isn't universal either:

Hello

--
Rick

• Install dependencies npm install
• Run the tests: npm test

• The EmailReplyParser is now exported directly. If upgrading from pre 1.0, change the following:

var EmailReplyParser = require('emailreplyparser').EmailReplyParser

to:

var EmailReplyParser = require('emailreplyparser')

• The parse_reply function is now called parse.
• The module no longer adds any methods to the String prototype. If your code was relying on the trim, ltrim, strim, gsub, reverse or chomp methods to be available on the prototype, you'll need to make changes.
