问题
Is there a pretty printing function in Clojure that would output data-structures like lists and structs in a human-readable way?
回答1:
clojure-contrib now has a pprint function.
The API documentation is at http://richhickey.github.com/clojure-contrib/pprint-api.html
回答2:
As Chouser has mentioned, in 1.3 pprint is moved into clojure itself.
http://clojure.github.io/clojure/clojure.pprint-api.html#clojure.pprint/pprint
You can (:require clojure.pprint) and start using it.
回答3:
A pretty printer for Clojure is available here.
回答4:
There was a post on the Clojure mailing list yesterday, where a few people posted some trial implementations of a pretty-printer. But as mipadi said, it's not finalized yet.
回答5:
Not yet, but the feature has been discussed and is (presumably) under development by a couple people close to Clojure.
回答6:
As the others have said, planned but incomplete. When clojure.contrib.pprint is moved into clojure itself, an update will be posted to its ticket.
