Hello Org-mode users!

I have repeatedly tried to use another programming language than elisp for
writing source blocks in org-mode, which I intended to use as functions inside
org-mode spreadsheets. So far without success.

Here is my latest attempt:

~~~~ START ~~~~
#+HEADER: :var dt1="uninitialized1" dt2="uninitialized2"
#+name: org-lob-timediff
#+begin_src scheme
(import
 (ice-9 format)
 (srfi srfi-19))


(define org-timestamp->time-utc
  (λ (timestamp-string)
    (let ([parsed-date (string->date timestamp-string "[~Y-~m-~d ~a ~H:~M]")])
          (date->time-utc parsed-date))))


(define duration->hours
  (λ (duration)
    ;; 1h = 60min = 3600s
    (/ (time-second duration) 3600)))


(define org-lob-timediff
  (λ (org-dt1 org-dt2)
    ;; formatting float:

    ;; ~@width, decimals, scale, overflowchar, padchar

    ;; ~ placeholder is following
    ;; @ with sign if negative
    ;; width: minimum width
    ;; decimals: minimum number of digits after decimal point
    ;; scale: ???
    ;; overflowchar: ???
    ;; padchar: char to use for padding

    (format #f
            "~,2f"
            (number->string
             (exact->inexact
              (duration->hours
               (time-difference (org-timestamp->time-utc org-dt2)
                                (org-timestamp->time-utc org-dt1))))))))
#+end_src

#+CALL: org-lob-timediff(dt1="[2021-01-01 Fri 00:00]", dt2="[2021-01-01 Fri 01:45]")

#+RESULTS:
~~~~  END  ~~~~

This code works just fine in geiser using GNU Guile:

~~~~ START ~~~~
scheme@(guile-user)> (org-lob-timediff "[2021-01-01 Fri 00:00]" "[2021-01-01 Fri 01:45]")
$4 = "1.75"
~~~~  END  ~~~~

However, when I C-c C-c the `CALL` line to actually run the code using library
of babel, as a precursor to using `org-sbe` inside a spreadsheet, it fails! I
see the following in my *Messages* buffer:

~~~~ START ~~~~
executing Scheme code block...

(dt1 '"[2021-01-01 Fri 00:00]")

(dt2 '"[2021-01-01 Fri 01:45]")

Starting Geiser REPL ... [3 times]
Guile REPL up and running!
Debug REPL. Enter ,q to quit, ,h for help.
=> ice-9/boot-9.scm:1685:16: In procedure raise-exception:
Wrong type to apply: #<syntax-transformer time-second>

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> 
Error during redisplay: (jit-lock-function 315) signaled (wrong-type-argument markerp nil)
Code block evaluation complete.
~~~~  END  ~~~~

So something obviously is getting confused. `time-second` is not a
syntax-transformer. It is a procedure:

~~~~ START ~~~~
scheme@(guile-user)> time-second
$5 = #<procedure %time-second-procedure (s)>
~~~~  END  ~~~~

Now I have many questions:

+ What am I doing wrong? How comes perfectly valid code does not work in LOB?

+ Can LOB even be used with other languages than Elisp?

+ Almost all examples I see online are elisp only. Perhaps I am trying to do
something, that is impossible with current Org-mode and Library of Babel?

Best regards,
Zelphir

I cannot help you directly with this but I can say that I use library of
babel with awk scripts successfully quite often.  Is the call within the
same document?  If it is, the issue won't be library of babel support in
any case, as far as I can tell.

Hi Eric,

the call in this case can be in the same document. I could copy the code to each
document I intend to use it in, without much of a problem. Neater would of
course be to have it in a global file, collecting all sorts of snippets/functions.

Regards,
Zelphir

Indeed.  I was asking for clarification: does the CALL work when in the
same document but not otherwise?  For me, I can access awk scripts from
other documents using LOB with no problem.

Zelphir,

actually...

Everybody,

i have an awkwardness about not being clear of the meaning of "Library
of Babel".  my sense is it a collection of "subroutines".

in my typical use of Org mode for programming, all my code blocks are
defined in the same .org file, and executed in that file, or tangled to
external files (normally, scripts).  i do use <<noweb>> to include bits
from one part of the same file to the code in another part.  i don't
know if this means i am using the Library of Babel or not.

then, on to...

Zelphir,

i also don't know what is going on.  but, installing geiser,
geiser-guile, and running your code from the source block, looking at
the output results, i get an error that might mean something to you?
see below.  (notice i embedded your call to =org-lob-timediff= at the
end of your source code.)

in addition to with elisp, i use org src blocks with R, shell scripts,
awk, etc.  but, never (till now!) with scheme.

hth.  good luck.  i'll be curious what your next steps are.

cheers, Greg

The CALL does not work at all for me, not even in the same document, while the
code works just fine in geiser. It results in and empty "#+RESULTS:" being
output below the "#+CALL: ..." and the error in *Messages*.

I did not mention, that I did the lob ingest step as well. Sorry for incomplete
information.

My Emacs version is:

~~~~ START ~~~~
GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.24, cairo version 1.16.0)
~~~~  END  ~~~~

And my version of org is:

~~~~ START ~~~~
Package org is built-in.

     Status: Built-In.
    Version: 9.4.4
    Summary: Export Framework for Org Mode
Required by: ob-async-20200921.205
Other versions: 9.4.6 (gnu).
~~~~  END  ~~~~

Thank you,
Zelphir

I love noweb and literate programming facilities. Have done the same thing
multiple times, especially, when there was some code I want to learn about and
understand or simply explain to my future self. My best example is at:

<https://notabug.org/ZelphirKaltstahl/the-little-schemer/src/master/chapter-09-y-combinator/code.org>
Big fan of noweb : )

Hmmm this might be a GNU Guile version difference. I remember something about
definition context changing in something like Guile 3.0.3 or so, allowing
definitions in more places than before. For me this error does not happen, as I
use GNU Guile 3.0.7 currently:

~~~~ START ~~~~
scheme@(guile-user)> (version)
$6 = "3.0.7"
~~~~  END  ~~~~

Perhaps org-babel for Guile (I think ob-scheme? or ob-guile?) wraps everything
inside another (define ...) and that causes an error with the definition context.

What I did notice before is, that the set locale seems to matter for the short
names of weekdays and can lead to an error, but that was on another laptop and
not on this system:

~~~~ START ~~~~
executing Scheme code block (org-lob-timediff)...

(dt1 '"uninitialized1")

(dt2 '"uninitialized2")

Starting Geiser REPL ... [3 times]
Guile REPL up and running!
Debug REPL. Enter ,q to quit, ,h for help.
=> ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure string->date: TIME-ERROR type bad-date-format-string: "[~Y-~m-~d ~a ~H:~M]"

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> 
Error during redisplay: (jit-lock-function 315) signaled (wrong-type-argument markerp nil)
Code block evaluation complete.
~~~~  END  ~~~~

But that is a Guile thing and nothing to do with LOB and easily fixed.

I began collecting small snippets and facts about whatever I learn about Emacs
in sone repository: https://notabug.org/ZelphirKaltstahl/emacs-usage-guide
<https://notabug.org/ZelphirKaltstahl/emacs-usage-guide>. Not much there yet,
but I will add a working example of LOB, if I can manage to get it working.
Perhaps I will also split that in a separate file.

I already got a small example working (not forgetting to run C-c C-v i or
`org-babel-lob-ingest` before C-c C-c on the CALL line):

~~~~ START ~~~~
#+HEADER: :var input-str="unspecified"
#+name: org-lob-upcase
#+begin_src scheme
(define upcase
  (λ (str)
    (string-upcase str)))

(upcase input-str)
#+end_src

#+CALL: org-lob-upcase(input-str="test")

#+RESULTS:
: TEST
~~~~  END  ~~~~

So it does not seem to be completely impossible then. The whole
syntax-transformer instead of procedure error message thing makes me think, that
perhaps it is not using the correct version of Guile or something, so I did the
following experiment:

~~~~ START ~~~~
#+name: org-lob-guile-version
#+begin_src scheme
(version)
#+end_src

#+CALL: org-lob-guile-version()

#+RESULTS:
: 3.0.7
~~~~  END  ~~~~

Seems to work fine.

So I still have not understood, what the actual issue is with the timediff
function. Perhaps it is something about the imports.

Thanks for taking the time to try and reproduce the behavior!

Best regards,
Zelphir

you're welcome.  if there's something else i might try, i'll be happy to
try (to try).

good luck.

I’m using scheme in org-mode during export (though not it tables) and
that works.
