Editing HTML blocks: no special environment to edit here

Editing HTML blocks: no special environment to edit here

[Karl Voit]

Hi!

Org-mode version 8.0.2 (release_8.0.2-121-g86fab4 from the git
repository a couple of weeks ago)

        #+BEGIN_SRC html
        bar
        #+END_SRC
        
        #+BEGIN_HTML
        foo
        #+END_HTML

I can edit "bar" in a separate buffer by invoking C-c '
(org-edit-special). However, this does not work for "foo"
("user-error: No special environment to edit here") although I guess
that the foo-html-block is the one that should be preferred.[1]

It is either rooted in my personal set-up, my (older) org-mode
version from git, or a general bug.

So I started Emacs with "--no-init-file" and got "Org-mode version
6.33x" (the site-specific org installation). After I evaluated the
statements to my local org-mode installation I got "Org-mode version
6.33x (release_8.0.2.121.g86fab)". Strange (6.33x vs. 8.0.2...) but
I hope this worked so far and I got the newer release from git.

In this rather minimal Emacs, I can edit both blocks as special
buffers as I want to.

So I guess I did something in my Org-mode setup files [2] which
causes this issue. Unfortunately, I could not locate anything which
I identify as the root of this issue.

Do you have any idea what this might be?


  1. There is not even an entry for "html" on 
     http://orgmode.org/worg/org-contrib/babel/languages.html

  2. https://github.com/novoid/dot-emacs -> org-mode.el

I did some additional tests and now I am sure that this is not
because of my org-mode.el configuration.

Can someone please test her/his current setup if BEGIN_HTML-blocks
can be edited by <C-c '> ? Thanks!

Damn.

However, I did a fresh "git pull" (release_8.0.7-384-g6fdc23) and
still get this behavior:

#+BEGIN_HTML
  bar
#+END_HTML

... cannot be edited via «C-c '».


Then I replaced by ~/.emacs with a file containing only the
following lines:

  ;; set paths to manually installed Org-mode (from git)
  (add-to-list 'load-path "~/.emacs.d/contrib/org-mode/contrib/lisp")
  (add-to-list 'load-path (expand-file-name "~/.emacs.d/contrib/org-mode/lisp"))

... and started using: «emacs --no-site-file org/test.org». This
should eliminate all local settings.

With «Org-mode version 8.0.7 (release_8.0.7-384-g6fdc23 @
/home/vk/.emacs.d/contrib/org-mode/lisp/)» I still can not edit HTML
blocks :-(


I am no Emacs pro. However, I tend to think that this is a bug in
Org-mode.

Or: what else can I check on my side?

I can too: Org-mode version 8.0.7 (release_8.0.7-380-g2a28de @

Maybe you can edebug-defun the function org-edit-special and step
through it to see where it goes astray in the html case.

First time I used edebug! Great experience :-)

OK, so I guess I nailed it down to the line which goes wrong:

«org-edit-special» is defined in «org.el»:

The line «(case (org-element-type element)» does not result
positively. Instead, it results to:

Result: (paragraph (:begin 182 :end 188 :contents-begin 182
:contents-end 188 :post-blank 0 :post-affiliated 182 :parent
(special-block (:type "HTML" :begin 169 :end 200 :hiddenp nil
:contents-begin 182 :contents-end 188 :post-blank 1 :post-affiliated
169 :parent nil)))) 

This way, the main routines are not executed. Instead, the line «(if
(eq (org-element-type...» gets evaluated next.

In short: «#+BEGIN_HTML» is not of element type «element» and thus
ignored by «org-edit-special».

I hope, I did not misinterpret the debugging result.

In case my interpretation is correct, it still seems to be a bug of
Org-mode and not my setup. So why does your setup work properly?

It only means that you didn't load `html' back-end. So the parser cannot
recognize "html" blocks as export blocks.

OK, two lines and even I with my limited ELISP-knowledge start to
see that I did blame Org-mode for no profound reason :-)

Sorry to be cumbersome but I could not find anything related to
«html back-end» in the documentation. Where do I have to look in
order to learn how to fix my issue?

Thanks!

All supported exporters are known as backends in Org lingo.  So I guess
you just need a: 

  (require 'ox-html)

Open source is the future. It sets us free.

Oh wow, it seems I missed a lot of export backends then (since 8.0).

I found [1] and [2] and added quite a number of require-statements
to my configuration :-)

Thanks for solving my issue - I am now able to edit HTML blocks!
