HTML export with ":export" parameter with Orgmode 9.0

HTML export with ":export" parameter with Orgmode 9.0

[Frederick Giasson]

Hi,


I am not clear about the change in the Export blocks that occurred in 
Org-mode 9.0


Does this change impact the ":export [...]" code block header parameter? 
What I am often using is this:


     http://orgmode.org/manual/Exporting-code-blocks.html


Which currently doesn't work but it is unclear from the release notes if 
it should or not and the code provided to fix the Export blocks doesn't 
appear to look for this syntax, so I guess it should still be working.


Anybody else experience this issue?


Thanks,


Fred

It seems other users experienced it, yet it is unexpected and I cannot
reproduce it even with a minimal init file.

Ok good. I will try to do some debugging on my side. I am wondering if 
it may not be a Windows issue, or some older 8.x configurations that may 
be at cause here.

Will keep you updated.

Thanks,

Fred

If you ever set the value of `org-export-babel-evaluate' to nil this might 
produce the behavior you describe.

In that case, see the docstring for advice.

HTH,

Maybe, but as stated in the manual: "Setting the 
org-export-babel-evaluate variable to nil will ensure that no code 
blocks are evaluated as part of the export process."

 From here: http://orgmode.org/manual/Exporting-code-blocks.html

The thing is that I indeed want to make sure that the code blocks are 
evaluated, but to me evaluation of code block is different than what to 
export from the Org file. It is often the case that I don't want export 
to evaluate anything, but just to export what is in the Org file's 
markup (while following what the header parameters say).

Thanks,

Fred

Argh! That paragraph needs to be revised.

Setting `org-export-babel-evaluate' to nil will ensure that NONE of your 
header arguments are followed.

Like the docstring says

  "Users who wish to avoid evaluating code on export should use the header 
argument ‘:eval never-export’."

It is tempting to `make-obsolete-variable' this variable and change its 
name to something that more completely describes what does not happen when 
set to nil.

Do you want to provide a patch for that?

It can be done for Org 9.1.

OK. I changed the name to `org-export-process-with-babel', which I hope 
suggests more profound actions than `org-export-babel-evaluate'.

I think the attached patch does this properly, but this is my first use of 
`define-obsolete-function-alias', so it might be best to check what I have 
done.

Subject: [PATCH] make-obsolete-variable `org-export-babel-evaluate'

* doc/org.texi: Better explain what the variable
  `org-export-process-with-babel' does.

* lisp/ob-exp.el: Small docstring change.

* lisp/org-compat.el: Define `org-export-babel-evaluate' as the
  obsolete alias for `org-export-process-with-babel'.

* lisp/ox-icalendar.el, lisp/ox.el, testing/lisp/test-ob-exp.el,
  testing/lisp/test-ob-lob.el, testing/lisp/test-ox.el: Change the
  obsolete variable name in many places.

Users were often confused that setting this variable to nil will cause
header arguments to be ignored in addition to preventing code from
being evaluated.  It is hoped that the documentation changes and the
name `org-export-process-with-babel' will better convey that everything
babel does can be switched off with this variable.

Thank you.

Thinking about it, wouldn't `org-export-use-babel' or even
`org-export-with-babel' (as `org-export-with-author'...) be simpler and
yet, as clear?

> Subject: [PATCH] make-obsolete-variable `org-export-babel-evaluate'

What about:

  Replace `org-export-babel-evaluate' with `org-export-process-with-babel'

Could you also specify the functions, or the manual section, being
modified?

OTOH, I don't think the chande made to "org-compat" requires an entry.

Nitpick: Org files

Nitpick: when Org is used as ...

Rationale : in both case, we refer to Org as a markup language, not as
an editing mode.

Could you add

  @vindex org-export-process-with-babel

above the whole paragraph?

I think it is cleaner to add :safe #'null in the defcustom.

You are right. `org-export-use-babel' it is.

Thanks for the suggestions. I pushed them to master just now.

Great, thanks for the clarification!

Re: HTML export with ":export" parameter with Orgmode 9.0

Hi Nicolas,

Ok I think I found the issue.

In all the files I worked on since I upgraded to 9.0 I had the following 
setting at the top of my org files:

=========
# -*- org-export-babel-evaluate: nil -*-
=========

In these notebooks, I don't want org-export to evaluate the code blocks, 
I want to do it manually (since some of them takes quite a while to run 
and I don't want to wait minutes to get an export).

In 8.x this was working perfectly. However, it appears that this 
behavior changed in 9.0. If I have that in place, then the :export 
header parameter is basically ignored and defaulted to "both".

Did this change and is this to be expected? If so, what should I use to 
get the same behavior?

Thanks!

Fred
