org babel: %% [removed source block]

org babel: %% [removed source block]

[Uwe Brauer]

Hi 

I have the following org file
#+BEGIN_SRC matlab :tangle test.m :padline no :results none
function [ll x]=mitest(A0,x0)
% initialization 
format long
epsi=1.e-3;
nit=0;
nmaxit=200;
Delta=10;
A=A0;
while Delta>epsi & nit<nmaxit
    nit=nit+1; % counter
#+END_SRC

The basic idea is.
That we do.
We also will

#+BEGIN_SRC matlab :tangle test.m :padline no
    y=A*x0;
end
#+END_SRC

Now org-babel-tangle works nicely, but when I try to export the org file
to latex via org-export-dispatch

I obtain a latex file in which the source code is removed. 

What do I miss??


I am asked in the export process whether I want to evaluate the code,
which I don't since it is a simple function not a code to be evaluated.

I think the default is
:exports results
so you what you want is either
:exports both
or
:exports code

Thanks, but I tried
#+begin_src matlab :tangle test.m  :export code   :wrap latex :padline no 
function [ll x]=mitest(A0,x0)
% initialization 
format long
epsi=1.e-3;
nit=0;
nmaxit=200;
Delta=10;
A=A0;
while Delta>epsi & nit<nmaxit
    nit=nit+1; % counter
#+end_src

The basic idea is.
That we do.
We also will

#+begin_src matlab  :tangle test.m :export both  :wrap latex :padline no 
    y=A*x0;
end
#+end_src


And I obtain always:

Maybe you need :exports and not :export.

I tried 

#+begin_src matlab :tangle test.m  :exports code :padline no 
function [ll x]=mitest(A0,x0)
% initialization 
format long
epsi=1.e-3;
nit=0;
nmaxit=200;
Delta=10;
A=A0;
while Delta>epsi & nit<nmaxit
    nit=nit+1; % counter
#+end_src

The basic idea is.
That we do.
We also will

#+begin_src matlab  :tangle test.m :exports code  :padline no 
    y=A*x0;
end
#+end_src


And obtain 

\begin{document}

%% [removed source block]
The basic idea is.
That we do.
We also will

%% [removed source block]
\end{document}

Anybody has a working example?

I tried also lisp

#+begin_src elisp :tangle test.el  :exports code :padline no 
(require 'ob-ipython)

(setq org-confirm-babel-evaluate t)   ;don't prompt me to confirm everytime I want to evaluate a block

;;; display/update images in the buffer after I evaluate
(add-hook 'org-babel-after-execute-hook 'org-display-inline-images 'append)
#+end_src

The basic idea is.
That we do.
We also will

#+begin_src elisp  :tangle test.el :exports code  :padline no 
(defun org-babel-execute:matlab-org (body params)
  "Execute a block of matlab code with Babel."
  (org-babel-execute:octave body params 'matlab))
#+end_src

But no, when exporting to latex the source code is removed.

[Berry, Charles]

I cannot reproduce your export issue with org 9.1.14.

You need to provide more details.

Perhaps you have a header-arg set that you have not told us about?

What does C-c C-v C-i report when point is in each of your source blocks? I get

Lang: matlab
Properties:
	:header-args 	nil
	:header-args:matlab 	nil
Header Arguments:
	:cache		no
	:exports	code
	:hlines		no
	:noweb		no
	:padline	no
	:results	none
	:session	none
	:tangle		test.m


for the first.

HTH,

Chuck

Ok, I searched already my custom settings.

Her is my output

The only difference I can find is the results/replace entry.

Not sure what to do.

Have you tried this with an emacs -q? Your examples work as expected in
emacs -q for me.

Sorry for the noise. I just realised that a very very long time ago I
installed a function  remove-src-blk-export, which, uhh, removes source
blocks. 

I removed that function and everything works as expected.

I was going to ask who produced that unfamiliar-looking "%% [removed
source block]" :-) Glad you figured it out.
