Hi All,
I'd like to let you know about issues I'm having while trying to put source
code blocks within lists.
Here's my example and how I indent it:
--8<---------------cut here---------------start------------->8---
* First situation
- My first bullet
We need to do this:
#+begin_src emacs-lisp
(message "this is a string")
(defun x()
"Doc..."
(interactive)
(message "hello"))
#+end_src
- My second bullet
#+begin_src emacs-lisp
"test"
#+end_src
#+results:
: test
- Sub-point of second bullet
We need to do this as well:
#+begin_src emacs-lisp
(sort)
#+end_src
--8<---------------cut here---------------end--------------->8---
This way if indenting code blocks has the following advantages:
- it looks nice;
- thanks to the indentation, you directly know at which list level the code
block belongs to;
- you can easily use Emacs commands (like `C-x TAB') on regions or Org
promote/demote commands on items or subtrees to edit and reorganize your
text: "relative" indentation is preserved in all cases.
But, I have 2 issues with it:
- when using `C-c '' (`org-edit-special'), I see spaces before my code, while
I would expect to see my code starting at column 0 in the edit buffer (the
"reference" column for the "margin" being, here, the column with the '#'
from '#+begin_src';
- when exporting, the spaces from column 0 to the start of my code are also
exported, while I would again expect these spaces to be ignored for the
export.
The only way I found to fix these issues is to edit my text like this (and
make any code to start in column 0):
--8<---------------cut here---------------start------------->8---
- My first bullet
We need to do this:
#+begin_src emacs-lisp
(message "this is a string")
(defun x()
"Doc..."
(interactive)
(message "hello"))
#+end_src
- My second bullet
#+begin_src emacs-lisp
"test"
#+end_src
#+results:
: test
- Sub-point of second bullet
We need to do this as well:
#+begin_src emacs-lisp
(sort)
#+end_src
--8<---------------cut here---------------end--------------->8---
But:
- as you can see, the text does not look anymore as nice as in the previous
example;
- I'm no longer able to edit and reorganize the text using Emacs `C-x TAB'
command. That command becomes "forbidden" as it can't correctly respect the
indentation requirements:
+ starting at column 0 for code;
+ relative for list items (depending on their depth);
- even Org promote/demote commands are buggy in this case: as a simple
example, when I try to promote (with M-Shift-Left) the last point "Sub-point
of second bullet" I get an error ("indent-line-to: Wrong type argument:
wholenump, -2" ) and the following half-baked result:
--8<---------------cut here---------------start------------->8---
- Sub-point of second bullet
We need to do this:
#+begin_src emacs-lisp
(sort)
#+end_src
--8<---------------cut here---------------end--------------->8---
The "#+end_src" line got misaligned.
So, my question is the following: is there a way to edit my text as shown in
the first example and edit/export it ignoring the "margin" spaces?
Any help is welcome.
Thanks a lot,
Francesco

Hello Francesco,
That won't help you, but I've already sent questions on this problem, last
year (Org < 8). See my post on
http://lists.gnu.org/archive/html/emacs-orgmode/2012-02/msg00247.html.
Though, it's (for me) still unfixed as of today.
The good news is that Nicolas seemed OK to look at it, and find a solution for
it...
Best regards,
Seb

AFAICS, your problem was solved. Could you point to what is still wrong?
I also cannot reproduce OP's problem. It may be related to
`org-src-preserve-indentation' value.

Hi Nicolas,

Thanks for your answer.
I checked the `org-src-preserve-indentation' variable and saw that it was non
`nil'.
Setting this variable to `nil' fixes the demonstrated issue. But, even then, I
still have an indentation problem.
In the following example (with `org-src-preserve-indentation' set to `nil'):
- in the first headline, I have a code block in a list which is correctly
exported ignoring the spaces due to the indentation of the Org list;
- in the second headline, I have the same source code but it is split in
several code blocks in order to better document it. The last 2 blocks are
not correctly exported as *all spaces before the code* (even those I
manually added) are ignored.
--8<---------------cut here---------------start------------->8---
* First situation
My list:
- Example which works
#+begin_src emacs-lisp
(if complex-condition
then-block
else-block)
#+end_src
* Second situation
My list:
- Example which does not work anymore
#+begin_src emacs-lisp
(if complex-condition
#+end_src
The "then" block does this:
#+begin_src emacs-lisp
then-block
#+end_src
The else-block does that:
#+begin_src emacs-lisp
else-block)
#+end_src
--8<---------------cut here---------------end--------------->8---
I think that only the spaces due to the Org indentation (here the number of
spaces before the `#' which delimits the source block, hence 2 spaces) should
be ignored.
IOW, just the "margin" should be removed, and the margin is (IMO) defined as
the spaces from column 0 up to the `#' character.
Thanks for your help.
Regards,
Francesco

Indeed. I have as well `org-src-preserve-indentation' set to `t', for the same
reason as pointed out: if I don't use it that way, then my code blocks which
have different relative depths are exported (in HTML) on the same level, as if
there was no indentation to respect.
So, yes, it does work if you don't need to preserve indentation, you're well
right. But, if not, the indentation is lost on export (and on source editing
with C-c ').
Best regards,
Seb

I have pushed a fix on maint (at least for the export part, the source
editing one is another story). Could you confirm it behaves as expected?

I confirm that the export is respecting the indentation up to the virtual
margin (represented by the # character). Excellentissimo!
Thank you ve-ry much...

I wanted to add that I tested your patch against my LP'ed .emacs file
(~10K lines)... which was then some sort of baptism of fire for it...
