I am not sure if I should start a new thread for this question - but since
it's building off of reading json, I decided to continue this thread :)
(de getJson (Spl File Url Oln)
(unless (info File) (on Oln))
(when Oln (out File (wget Url)))
(pipe
(in File
(while
(prin
(run (list (cons 'echo Spl))))
(when (till (list "," "}"))
(ifn (sub? "." @) (prin (pack (trim (chop @))) ".0") (prin
@)))))
(readJson)))
The question I have is about the way I've used the "Spl" parameter to
accept a list of special words to look for in the call to echo. Is this the
right approach?
