Exporting the results of code evaluation in org-babel by default

Question

I have these settings for evaluating emacs lisp code in babel:

ELISP> org-babel-default-header-args:emacs-lisp
((:eval . "never-export")
 (:exports . "both")
 (:hlines . "yes")
 (:colnames . "no"))

Here is an example document.

#+TITLE: Title

Here is some advanced math.

#+BEGIN_SRC elisp
 (+ 1 1)
#+END_SRC

#+RESULTS:
: 2

And here is some more.

#+BEGIN_SRC elisp
 (+ 2 2)
#+END_SRC

When I export this document to pdf, the results are not exported. Why not? org-version holds 8.2.10.

Answer 1

Because :eval . "never-export" means " The code block will not be evaluated during export but may still be called interactively". You can either change this to "yes", or leave it the way it is and do M-x org-bable-execute-buffer before exporting.

Edit: It looks like the issue was not unevaluated code blocks as I assumed in the original answer. Rather, you should use the official identifier emacs-lisp rather than elisp, i.e.,

#+TITLE: Title

Here is some advanced math.

#+BEGIN_SRC emacs-lisp
 (+ 1 1)
#+END_SRC

#+RESULTS:
: 2

And here is some more.

#+BEGIN_SRC emacs-lisp
 (+ 2 2)
#+END_SRC
