Email Reply Parser for Go

A Go port of GitHub's Email Reply Parser library. The library parses an email body into fragments, marking the fragments as quoted or as part of a signature as appropriate.

The most common use case is to get the text of a reply while ignoring signatures and the quoted original email. It properly parses top, bottom and inline replies.

Installation

To install emailreplyparser run:

go get github.com/recapco/emailreplyparser

Usage

The library can be used to get the reply text from an email body as such:

reply, err := emailreplyparser.ParseReply(emailBody)

The library can also be used to retrieve the signature. For example:

func Signature(text string) (string, error) {
	email, err := emailreplyparser.Read(text)
	if err != nil {
		return "", err
	}

	for _, fragment := range email.Fragments {
		if fragment.Signature {
			return fragment.String(), nil
		}
	}

	return "", nil
}

The library can also help discover quoted segments in an email. For example:

func Quotes(text string) ([]string, error) {
	email, err := emailreplyparser.Read(text)
	if err != nil {
		return nil, err
	}

	var quotes []string
	for _, fragment := range email.Fragments {
		if fragment.Quoted {
			quotes = append(quotes, fragment.String())
		}
	}

	return quotes, nil
}

Building and testing follow the normal Go conventions of go build and go test.
