func Decode ¶

func Decode(data string) ([]byte, error)

Decode decodes data as Gmail serves it, base64url-encoded, with or without padding.

func FindTextPart ¶

func FindTextPart(part *message_part.MessagePart, mimeType string) *message_part.MessagePart

FindTextPart returns the first part of the mime type that is text rather than an attachment, searching the parts in the order they appear. A message that is not multipart is its own single part.

func Text ¶

func Text(msg *message.Message, htmlToText func(source string) string) string

Text is the text of the message: its text/plain part, or, failing one, its text/html part read as text by htmlToText, which also reads a text/plain part that is an HTML document in fact, as some senders' are. A message with neither -- an image, a calendar invitation with no description -- has none, and nor has one of HTML alone when htmlToText is nil. A text/plain part keeps its indentation and its runs of spaces, which line its columns up.

Gmail serves a part's data in the message's own character set, which for mail is overwhelmingly UTF-8; what is not valid UTF-8 is read as Latin-1, which is right for the rest of what arrives and readable for anything else.
