I tried the newest version of newlisp,
newlisp -v
newLISP v.10.5.3 64-bit on Linux IPv4/6 UTF-8 libffi.
Get the newlispdoc codes from //http://newlisp.org/syntax.cgi?code/newlispdoc.txt
But when I use @return tag in comments, I just get result below
;; @return Returns cookie if login succeeds
It seems a bug in newlispdoc.
I figured out myself. Because I forgot to put @syntax on the top of my function.
It's a little bleak here.
