including the result of a block in several places?

including the result of a block in several places?

[Alan Schmitt]

Hello,

I tried including the result of evaluation a block in several slides,
but the second time it was not included. Here is the code I ran:

#+begin_src org
** Prototype-based objects

#+name: object_example
#+begin_src js :results code output :exports both
var f = function(a) {
	this.x = a
}

f.prototype = {y : 1}

var o = new f (42)

console.log("o.x = " + o.x + ", o.y = " + o.y)
#+end_src

Results

#+results: object_example

** Prototype-based objects

#+begin_src js
var f = function(a) {
	this.x = a
}

f.prototype = {y : 1}

var o = new f (42)

console.log("o.x = " + o.x + ", o.y = " + o.y)
#+end_src

Results

#+results: object_example

(Some additional images added)
#+end_src

I cannot do a "\pause" because a slide will be inserted in the middle.

Is it possible to have the results of the evaluation of a block in
several places?

Thanks,

Alan

OOTB, I don't think so. However, you could have a code block which simply
copies the results.

See `echo' in the `library-of-babel.org'.

Nice suggestion, thanks a lot. According to the documentation, I can
"call" functions from the library of babel from anywhere, but when I try
this:

#+begin_src org
#+name: test
#+begin_src perl
   for (my $i = 0; $i != 10; ++i) {
        print "hello, world!\n";
   }
#+end_src

#+call: echo(test)
#+end_src

I get a "org-babel-ref-resolve: Reference 'echo' not found in this
buffer".

Do I need to do something special to load the library?

I've had these in my .emacs for quite a while and they seem to work:

** ON Load Standard Library of Babel
#+begin_src emacs-lisp :tangle yes
  (org-babel-lob-ingest "~/.emacs.d/src/org-mode/contrib/babel/library-of-babel.org")
#+end_src

** ON Load Local Library of Babel
#+begin_src emacs-lisp :tangle yes
  (org-babel-lob-ingest "~/org/td-lob.org")
#+end_src

hth,
Tom

Thanks a lot, I'm now able to call the "echo" function.

Unfortunately it does not exactly do what I want (but I was not really
clear about what I wanted first). Here is the code I have (don't worry
about the code inside the blocks, the idea is that I want a source block
and its results on two different slides, without having to duplicate
them):

#+begin_src org
** Prototype-based objects

#+name: object_example
#+begin_src js :results code output :exports both
var f = function(a) {
	this.x = a
}

f.prototype = {y : 1}

var o = new f (42)

console.log("o.x = " + o.x + ", o.y = " + o.y)
#+end_src

Results

#+results: object_example

** Prototypes resolution

#+BEGIN_SRC coq
Inductive proto : heap -> field -> loc -> loc -> Prop :=
  | proto_null : forall h f,
      proto h f loc_null loc_null
  | proto_here : forall h l f,
      indom h l f ->
      proto h f l l
  | proto_next : forall h l f l' l'',
      ~ indom h l f ->
      binds h l field_proto l' ->
      proto h f l' l'' ->
      proto h f l l''.
#+END_SRC

** Prototype-based objects

#+call: echo(object_example) :results code output :exports both
#+end_src

My problem is twofold.
- The code from "object_example" is not repeated. I guess that here what
I want is to be able to export a source code block in several places. Is
it possible?
- The highlighting of the results in the "#+call:" line is not in
javascript syntax, and I don't know how to tell the call that the result
will be javascript.

Thanks again,

Alan

In a hurry, to repeat the code:

- use named blocks
- use Noweb expansion

That is:

#+name: mycode
#+begin_src coq
...
#+end_src

Inserted a first time here:

#+begin_src coq :noweb yes
<<mycode>>
#+end_src

and another one here:

#+begin_src coq :noweb yes
<<mycode>>
#+end_src

Best regards,
  Seb

Thanks a lot, that worked perfectly.

Another option would be,

1. use named blocks
2. use call lines

Thanks for the suggestion. I tried using a call line, but it does not
allow me to include the source code again (it's great to re-run the code
once more, though).

What call line did you try?

All the best,

This is what I tried

#+begin_src org
** Prototype-based objects

#+name: object_example
#+begin_src js :results code output :exports both
var f = function(a) {
	this.x = a
}

f.prototype = {y : 1}

var o = new f (42)

console.log("o.x = " + o.x + ", o.y = " + o.y)
#+end_src

Results

#+results: object_example

** Prototypes resolution

Some other slide

** Prototype-based objects

#+call: echo(object_example) :results code output :exports both
#+end_src

My problem with this was twofold: the code from "object_example" is
not repeated, and the highlighting of the results in the "#+call:"
line is not in javascript syntax.

Using a "noweb" approach solves both issues.
