Code blocks in lists?

Code blocks in lists?

[Sebastien Vauban]

Hello,

As demonstrated by the following ECM, it seems that I can't put code blocks
inside lists:

--8<---------------cut here---------------start------------->8---
* Installation

1. Download and install color-theme.

   #+begin_src emacs-lisp
   (add-to-list 'load-path "/path/to/color-theme-6.6.0")
   (require 'color-theme)
   #+end_src

2. Download and install color-theme-leuven.

   #+begin_src emacs-lisp
   (add-to-list 'load-path "/path/to/color-theme-leuven")
   (require 'color-theme-leuven)
   #+end_src

3. Restart Emacs.
--8<---------------cut here---------------end--------------->8---

exports to the following HTML page:

--8<---------------cut here---------------start------------->8---
* Installation

1. Download and install color-theme.

#+begin_src emacs-lisp
(add-to-list 'load-path "/path/to/color-theme-6.6.0")
(require 'color-theme)
#+end_src

1. Download and install color-theme-leuven.

#+begin_src emacs-lisp
(add-to-list 'load-path "/path/to/color-theme-leuven")
(require 'color-theme-leuven)
#+end_src

1. Restart Emacs.
--8<---------------cut here---------------end--------------->8---

I guess this is the same root cause as the problem I tried to described at
http://lists.gnu.org/archive/html/emacs-orgmode/2012-02/msg00247.html.

Here, the fact that it is an enumerated list makes the problem stand out.

Any advice?

Best regards,
  Seb

I still cannot reproduce it.

What happens if you eval:

  (let ((org-current-export-file (current-buffer)))
    (org-export-blocks-preprocess))

in your buffer?

* Before command

--8<---------------cut here---------------start------------->8---
1. Download and install color-theme.

   #+begin_src emacs-lisp
   (add-to-list 'load-path "/path/to/color-theme-6.6.0")
   (require 'color-theme)
   #+end_src

2. Download and install color-theme-leuven.

   #+begin_src emacs-lisp
   (add-to-list 'load-path "/path/to/color-theme-leuven")
   (require 'color-theme-leuven)
   #+end_src

3. Restart Emacs.
--8<---------------cut here---------------end--------------->8---

* Command to execute

--8<---------------cut here---------------start------------->8---
(let ((org-current-export-file (current-buffer)))
  (org-export-blocks-preprocess))
--8<---------------cut here---------------end--------------->8---

* After command

--8<---------------cut here---------------start------------->8---
1. Download and install color-theme.

#+BEGIN_SRC emacs-lisp 
   (add-to-list 'load-path "/path/to/color-theme-6.6.0")
   (require 'color-theme)
#+END_SRC

2. Download and install color-theme-leuven.

#+BEGIN_SRC emacs-lisp 
   (add-to-list 'load-path "/path/to/color-theme-leuven")
   (require 'color-theme-leuven)
#+END_SRC

3. Restart Emacs.
--8<---------------cut here---------------end--------------->8---

* Summary of the changes

The code blocks "meta data":
- is indented in column 0
- becomes uppercased
- gets a trailing space added

* Note

If I go at the end of (or just below) the text "3. Restart Emacs", and press
C-RET, I get:

--8<---------------cut here---------------start------------->8---
3. Restart Emacs.

4. 
--8<---------------cut here---------------end--------------->8---

in the "Before command" section, while I get:

--8<---------------cut here---------------start------------->8---
1. Restart Emacs.
2. 
--8<---------------cut here---------------end--------------->8---

in the "After command" section.

Hence, they do not share the same view on identifying the current list.

`org-export-blocks-preprocess' shouldn't do that. I assume you want to
preserve indentation in your blocks, but block boundaries shouldn't be
moved in any case.

Eric Schulte may have an opinion about this. I CC him. There's nothing
to do as far as lists are concerned, unfortunately.

Hi Seb,

Your example works as expected on my system (both with my config loaded
and without my personal config loaded).  Could you try to reproduce the
problem using Emacs -Q to see if the issue lies somewhere in your
configuration?

Hi Seb,

Sorry I missed the bit about `org-src-preserve-indentation', indeed
there was a bug in the block indentation during export.  I've just
pushed up a fix, please let me know if you continue to have problems.

With your fix, the above gets correctly exported. Thanks a lot to Nicolas for
finding out the problem, and to you for the fix.

However, if I change my list to something like this:

1. Download and install color-theme.

   #+begin_src emacs-lisp
   (add-to-list 'load-path "/path/to/color-theme-6.6.0")
   (require 'color-theme)
   #+end_src

   1. Download and install color-theme-leuven.

      #+begin_src emacs-lisp
      (add-to-list 'load-path "/path/to/color-theme-leuven")
      (require 'color-theme-leuven)
      #+end_src

      1. Restart Emacs.

         #+begin_src emacs-lisp
         (restart)
         #+end_src

The export (see HTML), while being semantically correct in the sense that code
blocks do belong to the items, seems wrong wrt the indentation, something like
this:

1. Download and install color-theme.

      #+begin_src emacs-lisp
      (add-to-list 'load-path "/path/to/color-theme-6.6.0")
      (require 'color-theme)
      #+end_src

   1. Download and install color-theme-leuven.

            #+begin_src emacs-lisp
            (add-to-list 'load-path "/path/to/color-theme-leuven")
            (require 'color-theme-leuven)
            #+end_src

      1. Restart Emacs.

                  #+begin_src emacs-lisp
                  (restart)
                  #+end_src

A bit like if the indentation was "doubled" each time. What do you think of
that?

Should I not use `org-src-preserve-indentation', maybe?[1]

Best regards,
  Seb

[1] BTW, GitHub seems to use that setting, as they show the same problem as I
had initially, when exporting README.org to HTML.

Hi Seb,

This indentation is an HTML/CSS issue, as far as I can tell Org-mode is
generating the correct HTML.

The `org-src-preserve-indentation' variable only effects the indentation
of code *inside* of code blocks, it shouldn't have any effect on this
issue.

Github uses a ruby library named "org-ruby" to export, it is an entirely
separate export implementation.

I don't think it's a HTML/CSS issue: if you look at the produced HTML, you see
respectively 3 whitespaces (or 6 or 9) in front of every line of the code
block.

That is: the "indentation" whitespaces in your Org buffer are copied over to
HTML. And, as the code blocks are now correctly indented under their parent
item, the leading whitespaces are further indenting the code blocks.

So, for me, there should be no extra whitespace added to the code block in the
PRE tags.

OK.

My fault, I thought you were talking about the indentation of the code
block as a whole, not the code *within* the code block.

Currently when the `org-src-preserve-indentation' variable is set it
preserves the indentation between the beginning of the line and the
beginning of the code, not the indentation between the beginning of the
code block and the beginning of the code, so for example the following
un-intuitive option would control the indentation within the code
blocks.

1. Download and install color-theme.

      #+begin_src emacs-lisp
(add-to-list 'load-path "/path/to/color-theme-6.6.0")
(require 'color-theme)
      #+end_src

   1. Download and install color-theme-leuven.

            #+begin_src emacs-lisp
(add-to-list 'load-path "/path/to/color-theme-leuven")
(require 'color-theme-leuven)
            #+end_src

      1. Restart Emacs.

                  #+begin_src emacs-lisp
(restart)
                  #+end_src

I think this is a feature of `org-src-preserve-indentation' which should
probably be changed to make using it with indented code blocks more
natural.  In this case, unless you need to preserve indentation within a
code block a simpler solution is to set `org-src-preserve-indentation'
to nil.

Hope this helps,
