by activate i mean display, in echo area, whatever it is i want to
display.  i think help-echo is a text property, and i might or might
not want to display it, depending.  and i might want to display the
other stuff even if there is no help-echo.

i use [and adore] org-link-minor mode in elisp mode.  it highlights
links and timestamps and makes links followable.  i even use
[[target]] <<target>> within elisp buffers, and org id links that go
from elisp to org and vice-versa.

if org-link-minor-mode is active in an elisp buffer, i can run the
following to detect whether cursor is over an org ts.

(defun hoka-eldoc-at-point ()
  (when (eq 'org-date (get-text-property (point) 'face))
    (format "%s"
            (when (fboundp 'alpha-org-time-span)
              (with-no-warnings
                (alpha-org-time-span))))))

then i get the time span in the echo area.  a time span is e.g. -1 for
yesterday.  it could just as well be a timestamp in a different format
or lang.  so that's great.  but i want mouse hover to do the same
thing, and to do so with a delay.  and i want links of course.

more generally, i might occasionally want /some/ eldoc type stuff and
/some/ help-echo stuff.

so org-link-minor-mode was useful in my case because it [i think it is
it] adds face property which can be used.  and i thought that might be
useful to you.  idk though.

in my case i find it a bit overwhelming to get whatever solution i use
for cursor to also work for mouse [with appropriate delays].  and get
whatever else to work and to not have anything annoyingly display.

Subject: na=\"nil\" in ob-R.elo
Message-ID: <87h7njdr0x.fsf@ufl.edu>
Content-Type: text/plain


Probably a silly question, but in ob-R.el, what is the reason for
setting na=\"nil\" when defining org-babel-R-write-object-command?  Is
this an elisp compatibility thing?

Regardless, I generally (always?) want na=\"\" for this, so I am finding
all those "nil"s very annoying, and the only way that I see to defeat
them is to redefine org-babel-R-write-object-command.

If there is no reason for the current behavior (doubtful I know) and if
I am not missing an obvious work-around, then I would like to suggest
changing this behavior.  Otherwise, would it be feasible to add an
option for R code blocks (:nastring?) where one could specify the NA
replacement string?

What do you think?  It's easy to suggest I know and certainly beyond my
elisp coding skills at present, but I am supposing that someone more
fluent in elisp could do this safely without too much trouble.

Hi, I'm new on this thread, but I can reproduce tak's issue and I
tried to do bisect.

Finally, I got 5b45c269cda09fe46e110adb6f6767040f4ade59 is a
commit has a some problem.

I'm happy if this information could help you.

Here is my bash script and do `C-c l` (org-table-copy-region) on
first table and `C-c ;` (org-table-paste-rectangle) on second table.
(~/dev/tmp/taks-file.tex have first tak's mention contents.)

```sh

Okay, your bisect scripts points to one of my commits.

But I wish it was more automated.  Because I tried quite
hard and sometimes I _could_ reproduce the problem and
sometimes I couldn't.  So you could be seeing noise here.
Maybe you can make your script  do those copy-paste
operations automatically and reliably?  Then we'd be sure.

Anyway, I think is might be enough to point to a bug
that was introduced by my commit, or rather exposed
by it.  I'll have another look.

In my setup, I'm using this:
---------------------------- Begin Quote -----------------------------
(org-add-link-type "mac-mail" 'org-mac-mail-link-open)

(defun org-mac-mail-link-open (mid)
  "Visit the email message with message id MID."
  (start-process "open-mail" nil "open" (format "message:%%3C%s%%3E" mid)))
----------------------------- End Quote ------------------------------

It gives me a new link type "mac-mail" for org-insert-link. Copy the
message ID (without the angle brackets) from Mail.app, and insert it as
the link location. This is a manual process, of course, but then I'm not
using it often, and I don't need it for anything else but Mail.app.

org-mac-link as suggested by Diego offers much more convenience by
automating the entire process, and by giving you access to many other
apps, too. So you might prefer that if you are going to use it often.


Hoping to have helped,
