[-- Attachment #1: Type: text/plain, Size: 1526 bytes --]

Hello,

Is it ok to apply the attached patch? I don't want to break anything.

I want to be able to denote my source blocks like so:

- *~* is the mark,
- *|* is the point

#+begin_src elisp
(~a b c| d e f g h i j k l m n o p q r s t u v w x y z)
#+end_src

- `org-edit-special' will automatically transform this markup into an
actual active region
- `org-edit-src-exit' will automatically transform an active region into markup

If anyone is interested, the implementation looks like this:

#+begin_src elisp
(defun org-src-denote-region (&optional context)
  (when (and (memq major-mode '(emacs-lisp-mode))
             (region-active-p))
    (let ((pt (point))
          (mk (mark)))
      (deactivate-mark)
      (insert "|")
      (goto-char (if (> pt mk) mk (1+ mk)))
      (insert "~"))))

(advice-add 'org-edit-src-exit :before #'org-src-denote-region)

(defun org-babel-edit-prep:elisp (info)
  (when (string-match "[~|][^~|]+[|~]" (cadr info))
    (let (mk pt deactivate-mark)
      (goto-char (point-min))
      (re-search-forward "[|~]")
      (if (looking-back "~")
          (progn
            (backward-delete-char 1)
            (setq mk (point))
            (re-search-forward "|")
            (backward-delete-char 1)
            (set-mark mk))
        (backward-delete-char 1)
        (setq pt (point))
        (re-search-forward "~")
        (backward-delete-char 1)
        (set-mark (point))
        (goto-char pt)))))
#+end_src

The only thing left to do is to patch `org-edit-src-code'.

regards,
Oleh

I don't understand what your use-case is. Note that `org-edit-special'
already preserves region.

Hi Nicolas,

> already preserves region.

That's good, but not what I need. I want to go from an unmarked region
in an org file with markup
to a marked region without markup in the *Org Src* buffer.

I've defined a custom `org-babel-edit-prep:elisp' that does this, but
it's not allowed to mark region in this function.  A patch to
`org-edit-src-code' is required for this.

Just to sum it up: I want a custom `org-babel-edit-prep:elisp' to be
able to mark region, even if it wasn't marked before.

regards,
Oleh

That still doesn't explain why you need it.

Why?

Your markup is very personal. I still don't see the need to turn it into
a general mechanism. Isn't an advice enough?

To automate things.
I'm writing a function reference for a package here:
  https://raw.githubusercontent.com/abo-abo/lispy/gh-pages/index.org.
Here's the link in case you don't want to compile the org-file:
  http://abo-abo.github.io/lispy/.

Some of the source blocks in this document feature a marked region
that I export marked to HTML.  Most source blocks are step-by-step
examples that assume a certain point and region state in order to
work.  And it's nice to automatically set the region state in order to
text out an example.

Well, I can call `set-mark' in this function, but it won't work unless
the function
that calls it binds `deactivate-mark' to nil.

Well, I'm not trying to push my markup or anything, I just want my
custom `org-babel-edit-prep:elisp' to be able to mark the region.
Currently I'm not given that option.

> Isn't an advice enough?

I don't know how this would work. `org-babel-edit-prep:elisp' is
already the exit point
of `org-edit-src-code' and it's not allowed to mark the region.

Oleh

Understood.

Would you mind providing a patch with format-patch, and reference the
current thread in the commit message?

I can just push it through if you don't mind. I have push access.

Is this OK as reference: http://article.gmane.org/gmane.emacs.orgmode/93053 ?

Sure, go ahead. Thank you.

It is.
