[O] [PATCH] Better handling labels in source code blocks + A suggestion

[Bernard Hurley]

Hi all,

At present the value of org-coderef-label-format in a source code
editing buffer does not inherit its value from the value in the
corresponding org-mode buffer but instead, if it is not specified by a
-l option, defaults to the global value. Note that it is the value in the
org mode buffer and not the global value that is used for such things as
exporting so this can lead to inconsistent behaviour.

The following patch on org-src.el will fix this, and, as far as I can
tell, it doesn’t break anything else:

(N.B. I’m using org-plus-contrib-20160725 and Emacs 25.1.50.1)

= snip=
*** org-src.old.el  2016-08-01 13:23:35.596041600 +0100
--- org-src.el  2016-08-01 13:34:08.420047376 +0100
***
*** 828,834 
  name of the sub-editing buffer."
(interactive)
(let* ((element (org-element-at-point))
!(type (org-element-type element)))
  (unless (and (memq type '(example-block src-block))
 (org-src--on-datum-p element))
(user-error "Not in a source or example block"))
--- 828,835 
  name of the sub-editing buffer."
(interactive)
(let* ((element (org-element-at-point))
!(type (org-element-type element))
!(local-coderef-label-format org-coderef-label-format))
  (unless (and (memq type '(example-block src-block))
 (org-src--on-datum-p element))
(user-error "Not in a source or example block"))
***
*** 862,868 
;; Finalize buffer.
(org-set-local 'org-coderef-label-format
 (or (org-element-property :label-fmt element)
!org-coderef-label-format))
(when (eq type 'src-block)
(org-set-local 'org-src--babel-info babel-info)
(let ((edit-prep-func (intern (concat "org-babel-edit-prep:" lang
--- 863,869 
;; Finalize buffer.
(org-set-local 'org-coderef-label-format
 (or (org-element-property :label-fmt element)
!local-coderef-label-format))
(when (eq type 'src-block)
(org-set-local 'org-src--babel-info babel-info)
(let ((edit-prep-func (intern (concat "org-babel-edit-prep:" lang
 snip ===

After this you can do things like the following in an org-mode buffer,
so that the labels are embedded in comments and the code block will
still execute:

# Local Variables:
# org-coderef-label-format: "#(ref:%s)"
# End:

and you could write something like:

#+BEGIN_SRC ruby -r

instead of:

#+BEGIN_SRC ruby -f -l "#(ref:%s)"

which is quite convenient if you have lots of blocks

A Suggestion:


In addition it would be nice if there were some way of giving a default
value for org-coderef-label-format that depends on the language of the
code block it is associated with, but I’m not sure what the best way to
implement this would be.

[O] [PATCH] Fix to allow ob-babel-shell-names to be customised.

[Bernard Hurley]

Hi all,

At present customisation of the variable ob-babel-shell-names in
ob-shell.el doesn't work properly.  You can actually change its value
and save the customisation, but the org-babel-execute: functions
get created for the hard coded value of the variable not the customised
value.

The following patch should fix it:

--- ob-shell.el 2016-07-22 22:55:28.730037538 +0100

Wow. Thanks for your reply. I will stop googling and worg-ing for a solution. I

  #+CAPTION:

 Here, image1 and image2 are displayed and resized in a single row. 
 But we don't know how to mix text within this block so that all is 
 displayed as a single paragraph with resized images.


This is not possible out of the box. You might use some Babel code to
generate the needed HTML but I guess it wouldn't be particularly easy.

Nevertheless, there's a solution. `html' back-end can redefine what
a paragraph is, instead of following Org's own definition. More
explicitly, an HTML paragraph can be defined as a cluster of elements
not separated by any blank line and containing at least an Org
paragraph. Hence:

  #+attr_html: :width 10%
  [[./img1.png]]
  Paragraph
  #+attr_html: :width 10%
  [[./img2.png]]

consists of two paragraphs in Org, but would be seen as a single
paragraph by HTML, and exported as such.

Implementation is simple using pseudo-elements. `latex' back-ends does
it already for tables and math snippets. However, I'm no HTML
specialist, so there may be drawbacks I cannot foresee.

Re: [O] resize multiple image within a row or paragraph

[alban bernard]

I will test this workaround pronto. For other backends, that's not a problem as 
I render pdf from html through phantomjs and I don't use neither latex nor odt 
for the moment. 


Big thanks to you both.

Hi,

Here's a simple CSS workaround that might or might not work well for
you, and won't work for non-HTML backends, but at least requires minimal
hacking: 

Wrap the sentence in a DIV element and define a class for it to force
child paragraphs to display as inline instead of blocks. 

You can set up the style sheets in various ways, but by way of
demonstration, add the style definition with HTML_HEAD export keyword:

#+HTML_HEAD: style.inlineparas p {display: inline;} /style

Then you can do things like  this:

#+html: div class=inlineparas
This is a phrase with
#+ATTR_HTML: :width 50%
[[./image1.png]]
and
#+ATTR_HTML: :width 50%
[[./image2.png]]
inline images.
#+end_inlineparas
#+html: /div

The generic #+begin_{block} syntax lets you do this in a more org-like
and less cluttered way:

#+begin_inlineparas
This is a phrase with
#+ATTR_HTML: :width 50%
[[./image1.png]]
and
#+ATTR_HTML: :width 50%
[[./image2.png]]
inline images.
#+end_inlineparas

Yours,
Christian

[O] rainbow parenthesis with org babel for reveal.js export

[bernard]

Dear list,

I am currently very happy to use orgmode and org-reveal [0] to create slide
for my lessons about programming.
I enjoy using src block to have automatic syntax highlighting for the code
fragments.
However, I now have the joy to teach a lisp variant (Clojure) for which I
have some syntactic coloring in HTML.
However, I miss rainbow parenthesis (and my students even more so !).
org-reveal page says : Org-reveal use Org-Babel to highlight source codes.
hence my message here.

Any advice would be greatly appreciated !

Best Regards

Bernard
