refernce to call results

refernce to call results

[Andreas Leha]

Hi all,

how do I reference the results of a #+call line?

Here are my unsuccessful attempts:

--8<---------------cut here---------------start------------->8---
* Test call results

#+name: curdir
#+begin_src sh
  echo "$PWD"
#+end_src

#+results: curdir
: /home/andreas/tmp/junk/2013/11


#+name: curdircall
#+call: curdir()

#+results: curdircall
: /home/andreas/tmp/junk/2013/11

#+begin_src sh :var test=curdircall
  echo "$test"
#+end_src

#+results:
: nil

#+begin_src sh :var test=curdircall()
  echo "$test"
#+end_src

#+results:
: nil

--8<---------------cut here---------------end--------------->8---


Regards,
Andreas

IIUC, #+CALL lines can't be named.

See http://orgmode.org/manual/Structure-of-code-blocks.html#Structure-of-code-blocks
 vs http://orgmode.org/manual/Evaluating-code-blocks.html#Evaluating-code-blocks.

Hi Sebastian,

they can be named now (see
http://thread.gmane.org/gmane.emacs.orgmode/73811/focus=74096).

Use the following:

#+begin_src sh :var test=curdir()
  echo "$test"
#+end_src

Hi Sebastien,

thanks for that.  I am aware of the workaround to use a full code block
instead.  But my question still stands.

I found out how to do it.  Rather simple and straight forward, blush...

For future reference here it is:
--8<---------------cut here---------------start------------->8---
#+name: curdir
#+begin_src sh
  echo "$PWD"
#+end_src

#+results: curdir
: /home/andreas/tmp/junk/2013/11


#+name: curdircall
#+call: curdir()

#+name: myname
#+results: curdircall
: /home/andreas/tmp/junk/2013/11



#+begin_src sh :var test=myname
  echo "$test"
#+end_src
--8<---------------cut here---------------end--------------->8---


Regards,
Andreas

I don't understand what you mean: it's not a workaround, as you have to define
your block once. Then, you simply use its name, instead of naming a call line,
and using that name. You avoid one indirection, no?

I don't know if that's the solution, or simply a feature which works for now.

I find this weird and unsound:

- For code blocks, the results' name (curdir) is the code block's name
  (curdir).

- For call lines, as you do above, you give another name to the results of a
  call line (myname) than the name of the call line itself (curdircall).

This is not appealing to me, and confusing at least.

Best regards,
  Seb

Sorry about the lame example.  Let's assume, the original
code block takes an argument.  I want
to 'get rid of' that argument, let's say to avoid typing.  So, I have to
name the result of calling that code block with a specific argument.
There has to be at least one level of indirection here?

IIUC, you propose to use a code block to provide that argument, and my
idea was to use a #+call line.  For me, a call line is the more natural
way to accomplish this.

I agree completely.  So my question boils down to this feature request:

Now, that #+call lines can be named, would it be possible to reference
the results the same way as for code blocks?

I just pushed up a commit which should make this possible.  E.g.,


[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #2: call.org --]
[-- Type: text/x-org, Size: 320 bytes --]

* call by name

#+name: echo-input
#+begin_src sh :var input="original"
  echo "input=$input"
#+end_src

#+RESULTS: echo-input
: input=original

#+name: echo-new
#+call: echo-input("new")

#+RESULTS: echo-new
: input=new

#+begin_src sh :var input=echo-new()
  echo "this=$input"
#+end_src

#+RESULTS:
: this=input=new

thanks a lot!  I confirm that it works.  This was really fast!
