Bug: export aborts if ':eval query/never' in source code blocks

Bug: export aborts if ':eval query/never' in source code blocks

[Paul Sexton]

#+BEGIN_SRC R :eval query
...
#+END_SRC

If the above is in an org file, the user runs an export (C-c C-e), and the user
types 'no' when asked whether to evaluate the code block, then the whole export
process is aborted (no further blocks are processed and no export output is
produced).

The same thing happens with ':eval never'.

Which version of org-mode? I can't replicate on git version from
minutes ago..

Hi Paul,

This is on the top of the stack for Babel bug fixes (see [1]), and I
hope to have a solution pushed up to the git repository soon.  I'll
reply to this email when this issue is resolved.

Thanks -- Eric

Re: Bug: export aborts if ':eval query/never' in source code blocks

Eric,

As a follow-up on a related issue:

What if I want to eval a code block for some side-effect, but
*not* include code or results in export. This assumes I'm using
:session.

Is there a way to currently do that?

Setting :exports none seems to block evaluating of the code,
can the :eval argument 'override' that so the block is
eval'd, but no export is produced.

In R, I currently can just put the last line of the block
I want this behavior for as

NULL

with :exports results

and it seems to do what I want.  Just wondering if there was
a more 'official' way?

Here's a sample file that seems to do as I want, with the
NULL trick.  Just wonder if :eval can help at all.

* I want only the 2nd block exported

#+begin_src R :exports results :session

x <- 2 + 3
NULL

#+end_src

#+begin_src R :session :exports results

x

#+end_src

this should be possible using the :results silent header argument, for
example the following should give the desired behavior

--8<---------------cut here---------------start------------->8---
** eval for side effect on export
- one plus one
  #+source: one-plus-one
  #+begin_src emacs-lisp :exports none :results silent
    (+ 1 1)
  #+end_src
- plus one is
  #+begin_src emacs-lisp :var two=one-plus-one :exports both
    (+ 1 two)
  #+end_src
--8<---------------cut here---------------end--------------->8---

Cheers -- Eric
