Hi
I'm currently trying to use org-modes literate programming capabilities
to write up a paper. So far it has been a joy to have the plotting code
and text in the same document. Thanks for all the work people here have
already put in to make this so easy.
I have run into a two small problems so far
* How can I use computed variables (string/int/float) in floating text?
I have for example calculated a autocorrelation time and now want to
use that calculated number in the text. The best solution I have
found so far is
#+name: print_acf_time
#+begin_src ipython :session :exports none
print(acf_time)
#+end_src
The autocorrelation time for the process is call_print_acf_time().
That is OK-ish but I have to write a special code cell for every
variable that I want to reference in my document. Is there another
method to export variables to be easily accessible in org-mode?
* reruning specific cells only one time after emacs was started
I have some cells that are long running and produce some variables
I later use for plotting or calculating related values. To avoid
recalculating I have added `cache: yes` to these cells. But they
are only run once across restarts of emacs or my interpreter session
in the background. When I start working again I would like to have a
way to rerun all code-cells independent of the fact if they are cached
or not. This would lead to a huge speed up in converting to latex for
me.
I appreciate any help with this.
best Max

Can't add anything! ;-)

See:
- inline Babel calls: ... call_<NAME>(<ARGUMENTS>) ... and/or
- inline code blocks: src_<LANGUAGE>{<BODY>}.

I don't understand why re-running code blocks which are cached is
a problem. Could you elaborate?
Best regards,

Yes I'm currently using inline babel calls.

I wanted a shortcut to rerun every code cell independent of cached
status. Looking again into the docs I found the short-cut
'C-u C-c C-v b'
This calls 'org-babel-execute-buffer'.

... to forcibly re-evaluate the blocks (even when marked ":cache"), yes.
OK, got it now!

Hi Max,
This is one bit of literate programming I haven't mastered myself yet. I generally have code blocks and print results, and then manually re-enter them in the paragraph below. I would like what you are looking for. The best solution I have, which I don't use often, is to use sessions and inline code.

For example, to insert the number three I could do the following, if a = 1 and b = 2, defined previously in session "foo": src_octave[:session foo]{a+b} {{{results(=3=)}}}
I've been thinking about other ways to achieve this... perhaps my code blocks update a table. That table might be included in the text for the reader. Then one code session reads it all in, so I have access to all results in one session and can use them in the text...
-k.
