Re: [O] Library of Babel confusion

[Lawrence Bottorff]

The docs have this example:

#+name: square

#+header: :var x=0

#+begin_src python

return x*x

#+end_src

#+call: square(x=6)

...so yes, "return", but with 

(defun myelsquare (x)

   (* x x))

isn't the final thing evaluated what is "returned" with Elisp? AFAIK there is no explicit return with Elisp. #+call can't really call a function, only named blocks of REPL-style calculator snippets?

Also, today I find that a new start of Emacs doesn't load my LOB file, i.e.,

(custom-set-variables

...

 '(org-babel-lob-files (quote ("~/org/worg/library-of-babel.org")))

...

was being blown off, i.e., not populating the org-babel-library-of-babel variable. But today org-babel-lob-injest does seem to work, i.e., it did populate org-babel-library-of-babel. I wonder what's up.

What doesn't work? You call `org-babel-lob-ingest', specify a file, and
it stores all source code blocks in the file for later use.

This should be #+call: write(...)

Your second block defines a function, but doesn't return its results.
"#+call: myelsquare(...)" expects to find a block named "myelsquare",
not an Elisp function named "myelsquare".
