Accessing the body a message programatically

Accessing the body a message programatically

Hello,

I need to extract some information from a message that is shown in
notmuch-mode, and I was able to easily get the from and subject of the
message. I now need to use the body, but I cannot find how to get it. I
assume I should use notmuch-get-bodypart-text, but I don't know how to
obtain the msg or part argument.

In addition, can I get access to the List-Archive header? I could do it
by spawning an external process to get the raw message, but it seems a
bit heavy handed.

Thanks,

Alan

If you mean interactively for a currently displayed message, have a look
at the function notmuch-show-current-part-handle, and the way it uses
notmuch-show-get-{message,part}-properties.

there is a couple of patches by Johan Parin currently under review
to provide a configurable set of headers. You can find them via

This is great, thanks. Here is what I did:

(defun as/notmuch-get-body ()
  (let* ((msg (notmuch-show-get-message-properties))
         (part (notmuch-show-get-part-properties)))
    (notmuch-get-bodypart-text msg part nil)))

I'll have a look.

Thanks again,
