Hi List,
just wondering (and curious) if this is a bug or (in some way) expected
behaviour:
Say point is at the beginning of the first line of an Org-mode source
block:
,------------------------------------------------
| #+begin_src plantuml :file er-class-diagram.png
| scale 600 width ... # point at beg-of-line
`------------------------------------------------
Now, when I call interactive command org-babel-mark-block' either with
'M-x org-babel-mark-block' or 'C-c C-v C-M-h', the body of the source
block is (visibly) marked as expected (transient-mark-mode is on).
But with the point at the same position, evaluating with 'M-:'
,--------------------------------------
| Eval: (org-babel-mark-block)
`--------------------------------------
returns the position of point without (visibly) marking the source-block
body.

cheers,
Thorsten

The function is called differently in the two cases:
* backtrace with ESC ESC : (org-babel-mark-block)
org-babel-mark-block()
eval((org-babel-mark-block) nil)
eval-expression((org-babel-mark-block) nil)
call-interactively(eval-expression nil nil)
* backtrace with M-x org-babel-mark-block
org-babel-mark-block()
call-interactively(org-babel-mark-block record nil)
command-execute(org-babel-mark-block record)
execute-extended-command(nil "org-babel-mark-block")
call-interactively(execute-extended-command nil nil)
I don't know if that accounts for the difference - my guess is that
it probably does, but I don't know how.

Interesting, I have to check what happens when I use this function in a
program. Kind of strange, though, is that a bug in
'org-babel-mark-block' - or in Emacs itself?

I think it may have been a temporary bug in Emacs.
Can you reproduce it with a recent Emacs?
Also, M-h is bound to `org-mark-element', which will mark a block
(the whole block, not just its content). You might find it useful
too!
Best,

My Emacs is fairly recent:
,--------------------------------------------------------------------------------
| GNU Emacs 24.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.6.4)
| of 2013-01-20 on eric
|
| Org-mode version 7.9.3e (7.9.3e-921-g4d5c79 @ /home/tj/gitclone/org-mode/lisp/)

Thats very useful, indeed.
But the same thing happens when calling 'org-babel-mark-block' or
'org-mark-element' with 'M-: (cmd)': cursor jumps to beginning of the
block/element, nothing is highlighted (transient mark mode), and doing
'M-w' does not put anything into the kill-ring. With 'M-x cmd',
highlighting and copying works.
Thats not really a problem for me - just a bit strange.

So maybe this is by design.
Similarily M-: (org-mark-element) RET does not highlight the
region, while M-x org-mark-element RET does.
Perhaps you can ask on emacs-devel for confirming this (or
maybe someone who knows better will chime in this thread!)

Hi List,
this was posted and discussed on the Org-mode mailing list, but without
any real conclusion if it is a Bug in Emacs - or something else. So it
was suggested to repost it here.
Say point is behind the closing parenthesis of the sexp in this Org-mode source
block:
,-------------------------------------
| #+begin_src emacs-lisp
| (+ 3 4) # point behind sexp
| #+end_src
`-------------------------------------
Now, when I call
,-----------------------------
| M-x org-babel-mark-block RET
`-----------------------------
or
,-------------------------
| M-x org-mark-element RET
`-------------------------
the body of the source block (or the whole source-block) is (visibly)
marked as expected (transient-mark-mode is on), and 'M-w' puts the
active region into the kill-ring.
But with the point at the same position, doing
,-----------------------------
| M-: (org-babel-mark-block) RET
`-----------------------------
or
,-------------------------
| M-: (org-mark-element) RET
`-------------------------
moves point to the beginning of source-block (body) and returns the
position of point without (visibly) marking the source-block body.
There is no region activated, 'M-w' puts nothing in the kill-ring.

You probably should not use this function in Lisp programs;
it is usually a mistake for a Lisp function to use any subroutine
that uses or sets the mark.
