class DiscourseEmailParser

github.com/github/email_reply_parser/blob/master/lib/email_reply_parser.rb

DiscourseEmailParser is a small library to parse plain text email content. The goal is to identify which fragments are quoted, part of a signature, or original body content. We want to support both top and bottom posters, so no simple “REPLY ABOVE HERE” content is used.

Beyond RFC 5322 (which is handled by the [Ruby mail gem]), there aren’t any real standards for how emails are created. This attempts to parse out common conventions for things like replies:

this is some text

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

… and signatures:

this is some text

--
Bob

Each of these are parsed into Fragment objects.

DiscourseEmailParser also attempts to figure out which of these blocks should be hidden from users.
