问题
There used to be this useful utility called show in clojure.contrib. Now, that it's deprecated, is there an equivalent to it?
Thanks!
回答1:
De-constructing show
to be more "simple", making available distinct pieces of re-usable functionality, was discussed by Stuart Halloway in a talk he give on clojure simplicity.
The resulting code makes use of clojure.reflect/reflect
and clojure.pprint/print-table
and standard clojure filter
:
(require 'clojure.reflect)
(require 'clojure.pprint)
(->> (clojure.reflect/reflect java.lang.String)
:members
(filter #(.startsWith (str (:name %)) "last"))
(clojure.pprint/print-table))

I refer you to the Where Did Clojure.Contrib Go document, which says about clojure.contrib.repl-utils:
Migrated to clojure.repl and clojure.java.javadoc. show functionality similar to clojure.reflect/reflect.
The clojure.reflect API documentation is here, and the clojuredocs.org examples are here.
