This is very useful. For me it was useful to be able to limit the
output to lines that contained a few selected letters.
(show String "pper")
=== public final java.lang.String ===
[82] toUpperCase : String ()
[83] toUpperCase : String (Locale)
nil
I could always C-C C-O to flush the long output, but I still
had to look through it. The change is obvious, but I'll copy it in
anyway. If you do change it, I can learn how to do it right. Thanks
again.
(defn show
"With one arg, lists all static and instance members of the given
class, or the class of the given object. Each entry is listed with
a number. Use that number as the second argument, and that member
will be returned which at the REPL can be used to get more detail
Use a String as the second argument to limit output to strings
that contain the second argument.
Examples: (show Integer) (show []) (show String 23) (show String
substr)"
([x] (show x nil))
([x int-or-str]
(let [c (if (class? x) x (class x))
items (sort (for [m (concat (.getFields c)
(.getMethods c)
(.getConstructors c))]
(member-vec m)))]
(if (instance? Number int-or-str)
(last (nth items int-or-str))
(do
(println "=== " (Modifier/toString (.getModifiers c)) c "
===")
(doseq [[i e] (indexed items)]
(if (or (nil? int-or-str) (.contains (second e) int-or-str))
(printf "[%2d] %s\n" i (second e)))))))))
