Pascal's Triangle – exports both test
(defun pascals-triangle (n)
(if (= n 0)
(list (list 1))
(let* ((prev-triangle (pascals-triangle (- n 1)))
(prev-row (car (reverse prev-triangle))))
(append prev-triangle
(list (map 'list #'+
(append prev-row '(0))
(append '(0) prev-row)))))))
(pascals-triangle n)
calling code blocks from inside table
(sqrt n)
executing an lob call line
This is an inline call call_echo(input="testing") embedded in prose. This is an inline call call_echo(input="testing")[:results vector] embedded in prose.
call_echo("testing") call_concat(1,2,3)
(format "%S%S%S" a b c)
exporting an lob call line
(* 2 it)
The following exports as a normal call line
Now here is an inline call call_double(it=1) stuck in the middle of some prose.
This one should not be exported call_double(it=2)
because it is
quoted.
Finally this next one should export, even though it starts a line call_double(it=3) because sometimes inline blocks fold with a paragraph.
And, a call with raw results call_double(4)[:results raw] should not have quoted results.
The following 2*5=call_double(5) should export even when prefixed by an = sign.
inline source block
Here is one in the middle

echo 2
echo 3
