change in calling remote code blocks?

change in calling remote code blocks?

[John Kitchin]

[-- Attachment #1: Type: text/plain, Size: 653 bytes --]

In org8 I used to be able to call remote code blocks (
http://kitchingroup.cheme.cmu.edu/blog/2016/02/09/Calling-remote-code-blocks-in-org-mode/
)

with a syntax like:

#+call: si.org:figure-1() :wrap html


And C-c C-c on that line would call a code block named figure-1 in the file
si.org and insert the results.

in org 9.1.6, this does nothing. Does anyone know if this got changed, and
if there is a new way to do that?

This sounds like a bug.

It does ring a bell. However, I couldn't find any reference to this
syntax or behaviour in the manual. Am I missing something?

I don't recall how I learned about that, I guess maybe in some library of
babel documentation somewhere. I confirmed it does work in 8.2.10, e.g.
just with emacs -Q.

There are a few changes in org 9 to org-babel-lob-execute-maybe
and org-babel-lob-get-info that seem to be the root cause of the change.
Notably, org-babel-lob-get-info now returns nil where it used to return the
"path" to the file and block.

So, if I put this into an org file

(progn
 (re-search-forward "call")
 (message "%s" (org-babel-lob-get-info)))   ;<- execute here


#+call: remote-call.org:test-block()

These get returned

In 8.2.10: "(remote-call.org:test-block() nil 0 nil)"
In 9.1.6: "nil"

I am not sure what all the differences are, but it seems to be where the
change in behavior came from.

You may try loading the file into the library of babel 
(org-babel-lob-ingest). Then, you can call the function without a 
reference to the file

#+CAPTION: s1.org
#+BEGIN_SRC org
   ,#+NAME: figure-1
   ,#+BEGIN_SRC python
     return 2 + 2
   ,#+END_SRC
#+END_SRC

#+CAPTION: t.org
#+BEGIN_SRC org
   ,#+CALL: figure-1() :wrap html

   ,#+RESULTS:
   ,#+BEGIN_html
   4
   ,#+END_html
#+END_SRC

Or missed feature?

I only found the evident:
#+BEGIN_QUOTE
By calling a named code block(2) from an Org mode buffer or
a table.  Org can call the named ‘src’ code blocks from the
*current Org mode buffer* or from the *“Library of Babel”*
#+END_QUOTE
(bold added by me).

It would be nice if it did :) .

Thanks for working so well on Org. I have good news: Someone to whom I 
introduced Emacs is now using it! (not my advisor... yet).

Fixed. Thank you. I also updated documentation and added tests.

As a side note, file:name syntax is a bit weak. It prevents using colons
in a name, as reported by the linter. I don't know if the feature is
used extensively but it may be worth considering changing references
syntax to, e.g, "file::name".

I agree. use `file::name` is better.
