Yeah, that works, and is my proposal for emacs-25, but I'm still leaning
towards solving this more broadly in with-silent-modifications, probably
also add a mention about this to the inhibit-modification-hooks
docstring.

I think doing the same to inhibit-read-only isn't worth the trouble
because if it happens to be let-bound to t in a buffer where it wasn't
"supposed" to be, the worst that happens is that an error *isn't*
thrown.

I looked briefly into Docker, but I did not make any progress on it.

[O] VM for org-based reproducible environment?

[Matt Price]

I'd like to provide a way for people to copy my course materials in the
easiest possible way. At present my export & grading processes rely on some
customization of various tools, mostly emacs-based. So I'm thinking the
easiest thing might be fore me to define a virtual machine, maybe
docker-based, and distribute that.

Is anyone already doing this? I remember maybe John K. saying something
along these lines a year or so ago, but can't find the details right away.
Would love to steal someone else's setup as I currently know nothing about
docker...

Thanks,
Matt

Make up your mind, will you? :-)

Re: [O] Is it possible to "properly" indent inside latex fragments?

Is it possible?


With export blocks you can get close.

If you type =C-c '= inside the following export block, you will get the 
contents in a latex buffer. Then indentation and other LATEX/P mode 
operations are available. When you exit with another =C-c '= the 
indentation is preserved.


#+BEGIN_EXPORT latex
\begin{displaymath}
  \begin{split}
a &= b \\
&+c
  \end{split}
\end{displaymath}
#+END_EXPORT


HTH,

[O] raising frame on capture hack

[Alan Schmitt]

Hello,

I'm using the following hack to raise the emacs frame when doing a
capture from outside emacs:

#+begin_src emacs-lisp
  (defun as/raise-frame ()
(select-frame-set-input-focus (selected-frame)))

  (add-hook 'org-capture-mode-hook 'as/raise-frame)
#+end_src

Is there a better way?

Thanks,

Alan

Here is how I did it:
- on Firefox side, I installed Org-capture for Firefox
  http://chadok.info/firefox-org-capture/. Alternatively, you can do it
  manually by following http://weblog.zamazal.org/org-mode-firefox/ (in
  the “The advanced way” section)
- I "(require 'org-protocol)" and have installed the "org-board"
  package.
- I setup a capture template like this:
  #+begin_src emacs-lisp
  (setq as/org-board-capture-file "my-org-board.org")

  (setq org-capture-templates
`(...
  ("c" "capture through org protocol" entry
(file+headline ,as/org-board-capture-file "Unsorted")
"* %?%:description\n:PROPERTIES:\n:URL: %:link\n:END:\n\n Added %U")
  ...))
  #+end_src
- I added a hook to org-capture-after-finalize-hook
  #+begin_src emacs-lisp
  (defun as/do-org-board-dl-hook ()
(when (equal (buffer-name) (concat "CAPTURE-" as/org-board-capture-file))
  (org-board-archive)))

  (add-hook 'org-capture-before-finalize-hook 'as/do-org-board-dl-hook)
  #+end_src

(Note: I mistakenly said that the "prepare" hook worked, but that would
download the file even when cancelling, which was wrong)

I think this is it.

Best,

Alan

Thanks, this was most helpful. org-capture-prepare-finalize-hook worked
great.

[O] Mobile org

[Paul Schlesinger]

For about two weeks since getting a new ipad I have not been able to
re-install mobile org. After setting up dropbox I can log in from MobileOrg
but the target directories are not created and they are not use if I create
them manually. This seems to me to be resulting from a change in dropbox.
Perhaps these are anticipated by the promise of a version 1.71 that appears
to be expected but not available. I would appreciate direction to
installation instructions that are current or other explanation.


Thank you

Paul Schlesinger

Re: [O] Table formula from code block

[Michael Welle]

Hello,

I think there are several problems, starting with BEGIN_SRC sh and some
more. But fixing them doesn't bring success. I even have trouble to get
a minimal example to work:

#+NAME: foo
#+BEGIN_SRC emacs-lisp
(+ 4 4)
#+END_SRC


|  bar   | foo|
|+|
| 42 | #ERROR |
#+TBLFM: $2='(org-sbe "foo")::$1=42


I'm not sure, what the problem is. Looking at org-sbe there is
something, I don't understand. In the end org-babel-execute-src-block is
called. That executes the _current_ source code block. But I don't
understand, how foo (in this example) becomes the current source code
block. Can someone explain, please? Is there a side effect, I don't see?
Or maybe a regression?
