following up to my own post, I wonder how printing does work in the
*Messages* buffer?
Looking at the examples below, I see that - with `print-circle' set to t
- `print' and `(message "%S" ...)' produce the output I want to receive
in another program. And what I want is the first part of the output, the
unquoted lisp structure, not the second (string) part.
I wonder how this first part (the return value of
`org-element-parse-buffer' I would guess) is captured and printed
unquoted in the *Messages* buffer _with_ the 'circular' labels and
references?
To send something via stdout to another program, one must print
something, so what I receive in the other program is always the the
output - either unquoted but without the 'circular' labels and
references, or quoted and including them.
How can I send the raw lisp structure with print-circle information
to another program (instead of a string)?
