Could you add an option to disable evaluation of code blocks when exporting? If I
have an org-file with many code blocks setup for evaulation (babel), when I export, I get
prompted for every code block. Also the prompt does not clearly show which code block it's
asking to evaluate.

One solution would be to have org-export-dispatch have an option at top which says whether or
not to evaluate code blocks during export. It should be configurable to be on or off. I would
suggest off as I see most of us running the evaluation as we write the code and not during
export.

I'm able to work around this issue by adding advice, e.g.

  (defun sb-org-export-dispatch-no-babel (orig-fun &rest args)

    (let* ((org-babel-default-header-args
           (cons '(:eval . "never-export") org-babel-default-header-args))
           (result (apply orig-fun args)))
      result))

  (advice-add 'org-export-dispatch :around #'sb-org-export-dispatch-no-babel)

Thanks
John

What is wrong with :eval no-export header? You can set it globally,
file-wise, tree wise, or per block.

It would be very nice if I could enable/disable the evaluation of code blocks during the export process in the interactive C-c C-e environment.

I do now see that I can use the :eval no-export header more effectively, so this is less of an issue, but still think it would be a nice enhancement to have control from within the interactive org-export-dispatch function.

Thanks
John

I'm not sold to this idea. There are already many ways to control
evaluation of Babel code, i.e., :eval header arguments in its multiple
forms, `org-export-use-babel'.

Adding one more could also add confusion.

Hi

Perhaps, in the interactive C-c C-e mode there could be:

 [C-e] Eval code blocks:  always | never | use-eval-header-setting

where 'use-eval-header-settings' is the default and uses whatever was set by the current org file and emacs session. Always and never would override that.

Consider the scenario where a number of people are working on a common overall "book" which is constructed from many org-files. The "hardcoded" setting of :eval no-export header in individual blocks would mean that I cannot interactively enable or disable the evaluation of the blocks.

Part of my confusion was that it took a little bit to figure this out (I ended up debugging the lisp code to get what I wanted). I think this could be improved in the doc, though I do admit, I'm not entirely clear on all the ways to control evaluation of code blocks during export. If I were, I'd propose something for the org manual.

Thanks
John

As I said, this would add an indirection level to an already complicated
topic.

Moreover, toggles in the export interface are never duplicates from
in-buffer settings, so far. This would set a precedent, and might be
a sign that this isn't right.

Why would you add :eval no-export to every block in the first place? In
this situation, there should be a global setting, which could be
overridden locally with appropriate header arguments.

Having a global way, even dynamic, to override every setting in the
buffer doesn't seem very useful. It is imprecise; some blocks could
still be used to set up export process. I assume there's a good reason
if a source code block specifies :eval yes.

I think the starting point is in (info "(org) Exporting Code Blocks").
Improvements to the manual are welcome, of course.

Hello,

I understand the frustration of not being able to bend emacs to ones
immediately. But many times my initial workflow turned out not to be the
best one. I just wanted to share my workflow hoping that it might be a solution to
the original post problem.

>> Consider the scenario where a number of people are working on a common
>> overall "book" which is constructed from many org-files. The
>> "hardcoded" setting of :eval no-export header in individual blocks

At some point, I experienced the same problem and as the document get
larger and larger it tends to complicate the management of code block
evaluation. I have found two solutions to this problem using existing
org-mode features.

* First
use global property header :eval yes, but evaluate only the sub-tree of
interest when the need comes. For a book it might be a part, a chapter
(even a paragraph by artificially creating a sub-tree at the desired
point). In that way you have only one trigger to push to disable
evaluation for the entire document.

To makes things quicker one can define a way to  change :eval
from yes to no very quickly. (I use point registers for this purpose
(info "(emacs) Registers"), but you could imagine a function with
key-bindings)


* Second

The second solution could be to use checkpoints with cache for
instance. Let say that, one wants to work on Part 1 only and wants to
evaluate code just for this part then. The following work flow might be suitable.

* Part 1
  :PROPERTIES:
  :header-args: :eval yes :cache yes
  :END:

#+BEGIN_SRC matlab
A = [16 3 2 13; 5 10 11 8; 9 6 7 12; 4 15 14 1]
#+END_SRC

 ** strip the header row
 #+BEGIN_SRC matlab
 A = [1 ; 2],  B = A.', C = transpose(A)
 #+END_SRC


* Part 2
  :PROPERTIES:
  :header-args: :eval no :cache yes
  :END:

#+BEGIN_SRC matlab
ones(3,3)
#+END_SRC

HTH,

Jeremie
