We might not always want a full export of an org heading to html for sending an email. Eric Brown would like to just send something that looks like what he sees in org-mode. There is another way to get html from emacs: htmlize! Here is an example. Eric: if this is what you mean, see my modified org-mime.el at [[https://github.com/jkitchin/scimax/blob/master/org-mime.el]]. 

The command to send a subtree is: [[elisp:org-mime-subtree-htmlize]]


#+BEGIN_EXAMPLE
My comment was motivated by other usage where I wish that I could simply
wrap an entire simple text, whitespace-formatted email message,
e.g. generated from org export to a plain text buffer, with a Monospace
directive so that webmail users could appreciate what I see with Sans
Mono.
#+END_EXAMPLE

| a | b | c |
| 4 | 5 | 6 |

An equation \(e^{i\pi} + 1 = 0\)

A figure: 

#+NAME: fig-particle

html-email in org-mode

* DONE Sending html emails from org-mode with org-mime
On the org-mode mailing list there was some discussion about sending html mail using orgmode. The support for this in mu4e is deprecated. There is the org-mime library though, and it supports a lot of what is needed for this. I am going to send this post to the orgmode mailing list as an html mail to make sure it works. It should show as a text mail in mu4e, and an html mail in a browser.


As I played around with it though, I came across some limitations:

1. I found equations were not rendered as images in the html, and files (in links) were not attached out of the box. I fixed that [[id:14317E51-C65E-48DD-9B52-B94D6B458E8F][here]].
2. I found it useful to modify the org-mime commands to leave point in the To: field when composing emails from org-buffers.
3. For use with mu4e, I created a function to open a message in org-mu4e-compose-org-mode, and added a C-cC-c hook to allow me to send it easily [[id:D44F059D-180C-41C5-BA0A-873723E0DDFB][(here)]].

This post documents some work I did figuring out how to send html mails. After some testing, some of these should probably be patched in org-mime.

First, you need to require this library.

#+BEGIN_SRC emacs-lisp
(require 'org-mime)
#+END_SRC

You can send a whole org buffer in html like with this command: [[elisp:org-mime-org-buffer-htmlize]]. Not all of the internal links work for me (at least in gmail).

The default behavior leaves you at the end of the buffer, which is not too nice. We lightly modify the function here to leave in the To: field.

#+BEGIN_SRC emacs-lisp
(defun org-mime-org-buffer-htmlize ()
  "Create an email buffer containing the current org-mode file
  exported to html and encoded in both html and in org formats as
  mime alternatives."
  (interactive)
  (org-mime-send-buffer 'html)
  (message-goto-to))
#+END_SRC

** From an org-headline in an org-file
You can compose an email as an org-heading in any org-buffer, and send it as html. In an org-heading, you need to specify a MAIL_FMT property of html, e.g.:

#+BEGIN_EXAMPLE
   :PROPERTIES:
   :MAIL_FMT: html
   :END:
#+END_EXAMPLE

Note the following properties can also be set to modify the composed email.
#+BEGIN_SRC emacs-lisp
	   (subject (or (funcall mp "MAIL_SUBJECT") (nth 4 (org-heading-components))))
	   (to (funcall mp "MAIL_TO"))
	   (cc (funcall mp "MAIL_CC"))
	   (bcc (funcall mp "MAIL_BCC"))
#+END_SRC

Then, send it with [[elisp:org-mime-subtree]]

Here I modify this function to leave me in the To: field.

#+BEGIN_SRC emacs-lisp
(defun org-mime-subtree ()
  "Create an email buffer containing the current org-mode subtree
  exported to a org format or to the format specified by the
  MAIL_FMT property of the subtree."
  (interactive)
  (org-mime-send-subtree
   (or (org-entry-get nil "MAIL_FMT" org-mime-use-property-inheritance) 'org))
  (message-goto-to))
#+END_SRC

** In a mail message
You might prefer to do this directly in an email. Here is how you can do it in mu4e. I use this command to open a message in org-mode. The mode switches if you are in the header, or in the body. If you always do this, you could use a hook instead on message-mode. I do not want default html so I do not do it. 

#+BEGIN_SRC emacs-lisp
(defun mu4e-compose-org-mail ()
 (interactive)
 (mu4e-compose-new)
 (org-mu4e-compose-org-mode))
#+END_SRC

For sending, we will use org-mime to htmlize it, and add a C-c C-c hook function to send it.  This hook is a little tricky, we want to preserve C-c C-c behavior in org-mode, e.g. in code blocks, but send it if there is no other C-c C-c action that makes sense, so we add it to the end of the hook. Alternatively, you could bind a special key for it, or run the special command. Note the C-c C-c hook only works in the body of the email. From the header, a plain text message is sent.

#+BEGIN_SRC emacs-lisp
(defun htmlize-and-send ()
  "When in an org-mu4e-compose-org-mode message, htmlize and send it."
  (interactive)
  (when (member 'org~mu4e-mime-switch-headers-or-body post-command-hook)
    (org-mime-htmlize) 
    (message-send-and-exit)))

(add-hook 'org-ctrl-c-ctrl-c-hook 'htmlize-and-send t)
#+END_SRC

Here is a way to do this for non-mu4e users. It doesn't have the nice mode switching capability though, so you lose completion in emails, and header specific functions. You can switch back to message-mode to regain those.

#+BEGIN_SRC emacs-lisp
(defun compose-html-org ()
  (interactive)
  (compose-mail)
  (message-goto-body)
  (setq *compose-html-org* t)
  (org-mode))

(defun org-htmlize-and-send ()
  "When in an org-mu4e-compose-org-mode message, htmlize and send it."
  (interactive)
  
  (when *compose-html-org*
    (setq *compose-html-org* nil)
    (message-mode)
    (org-mime-htmlize) 
    (message-send-and-exit)))

(add-hook 'org-ctrl-c-ctrl-c-hook 'org-htmlize-and-send t)
#+END_SRC

** Equations and file attachments do not seem to work out of the box
\(e^{i\pi} - 1 = 0\)

Out of the box, org-mime does not seem to attach file links to emails or make images for equations..

[[file:html-email.org]] 

Here is an adaptation of org-mime-compose that does that for html messages.

#+BEGIN_SRC emacs-lisp
(defun org-mime-compose (body fmt file &optional to subject headers)
  (require 'message)
  (let ((bhook
	 (lambda (body fmt)
	   (let ((hook (intern (concat "org-mime-pre-"
				       (symbol-name fmt)
				       "-hook"))))
	     (if (> (eval `(length ,hook)) 0)
		 (with-temp-buffer
		   (insert body)
		   (goto-char (point-min))
		   (eval `(run-hooks ',hook))
		   (buffer-string))
	       body))))
	(fmt (if (symbolp fmt) fmt (intern fmt)))
	(files (org-element-map (org-element-parse-buffer) 'link
		 (lambda (link)
		   (when (string= (org-element-property :type link) "file")
		     (file-truename (org-element-property :path link)))))))
    (compose-mail to subject headers nil)
    (message-goto-body)
    (cond
     ((eq fmt 'org)
      (require 'ox-org)
      (insert (org-export-string-as
	       (org-babel-trim (funcall bhook body 'org)) 'org t)))
     ((eq fmt 'ascii)
      (require 'ox-ascii)
      (insert (org-export-string-as
	       (concat "#+Title:\n" (funcall bhook body 'ascii)) 'ascii t)))
     ((or (eq fmt 'html) (eq fmt 'html-ascii))
      (require 'ox-ascii)
      (require 'ox-org)
      (let* ((org-link-file-path-type 'absolute)
	     ;; we probably don't want to export a huge style file
	     (org-export-htmlize-output-type 'inline-css)
	     (org-html-with-latex 'dvipng)
	     (html-and-images
	      (org-mime-replace-images
	       (org-export-string-as (funcall bhook body 'html) 'html t)))
	     (images (cdr html-and-images))
	     (html (org-mime-apply-html-hook (car html-and-images))))
	(insert (org-mime-multipart

This makes it pretty nice to send rich-formatted html text to people.

Hi John,

I haven't (yet) found the email thread that you had alluded to, but I
think this post is awesome.  Works well for me!

One suggestion/thought:

I would like to do is force monospace font in these messages, since the
recipients I typically send to will have variable width fonts, and
tables and the like tend to get messed up.

How might this be done?

Best regards,
Eric

+20! (that is, +2432902008176640000)

I'm not very interested in sending HTML emails, but this would be
AWESOME.  I sometimes send ASCII-art-ish tables (like Org-mode ones, or
Ledger reports) by email, and opening them in variable-width font is
rather messy indeed.

TIA,

Re: html-email in org-mode

[John Kitchin]

Do you mean monospace in the whole html message, e.g. something like Courier?

Or just in a table? I do not think you can control the font in plain
text emails.

You can set the font in the td elements of a table like this (I used
cursive because it was easy to see.

#+BEGIN_SRC emacs-lisp
(defun italicize-table (data backend info)
  (with-temp-buffer
    (insert data)
    (goto-char (point-min))
    (while (re-search-forward "<td" nil t)
      (replace-match "<td style=\"font-family:cursive;\""))
    (message"got %s" (buffer-string))
    (buffer-string)))


(add-to-list 'org-export-filter-table-functions 'italicize-table)
#+END_SRC

After you run that, the tables in html have italicized/cursive elements
in them. And probably all other exports to html too ;)

Thanks, this is extremely useful, as well.  In retrospect, I think my
question may be a bit moot, as the HTML formatting would probably allow
tables to remain aligned regardless of length of any one cell.

My comment was motivated by other usage where I wish that I could simply
wrap an entire simple text, whitespace-formatted email message,
e.g. generated from org export to a plain text buffer, with a Monospace
directive so that webmail users could appreciate what I see with Sans
Mono.

It's looking great in gnus, by the way. Equations and images are

[-- Attachment #1.1: Type: text/plain, Size: 1013 bytes --]

John, I'm moving this over to this thread because I think my issues with
htmlize-and-send might not be because of any errors in my setup.

When I use John's htmlize-and-send, or any similar function, to attempt to
send an html email from org-mode, I get an error from message-send:
"Message already sent via mail; resend?" Attmepting to resend fails
silently, and the message is neither sent nor saved to archives.
Interestingly, the first time I try this in a new emacs session, I get no
error message ( though the message doesn't actually get sent). This makes
me wonder if there's something wrong with the way
mu4e/message/htmlize-and-send is keeping track of messages.

I've attached the minimal mail-test.el that I use to start emacs; I'm using
a pretty recent emacs-git with the latest org-mode git, on Arch Linux, with
offlineimap and nullmailer (which has a sendmail clone). If anyone out
there has a moment to look at my config and tell me if they see anything
wrong... I'd aprreciate it. Th
anks,

Matt

I can not reproduce your error.

I feel like when I saw that error it was from calling a send command
while in org-mode, and not in message-mode.

Re: html-email in org-mode

[Joseph Vidal-Rosset]

Many thanks John for this email and also for your very useful videos.

As I told you, I use sometimes gnus + org-mode to make roughly the
same things that  you make with m4ue. Your message  appears correctly in
two formats  in gnus: multipart/mixed  and text/html. In a  browser used
with gmail its html is perfect.

I confess  that I  do not  succeed to use  only gnus  for my  email, but
mainly    when    it    is     more    convenient    for    professional
reasons. Unfortunately, I have not still succeed to use gnorb, because I
do not  understand clearly how  it works.  But even without  gnorb, gnus
works well in harmony with gmail in IMAP.

Maybe some  people in this  list could  share their experiences  with an
emacs email  client + org-mode  and help to  make the better  choice, if
possible?

Best wishes,

Jo.
