My mind is blown - yet again. I love it just looking at it. I'll have to
look a little more to see what's going on.
How do I capture the output though - I mean this does not capture the
output in J
(setq J (pipe
(in '("curl" "-s" "https://api.iextrading.com/1.0/stock/aapl/chart/3m
")
(while
(prin
(echo "volume" "unadjustedVolume") )
(echo ",")
(prin ".0,") ) )
(pretty (readJson)) ))
Regards,
Kashyap
