You can programmatically create keywords that are illegal as literals, i.e., will not be accepted by the reader.
This is not a fault of clojure.core/pr – if it is given a value that uses legal (readable) keywords, its result will indeed be readable by clojure.core/read-string. You can also programmatically create symbols that are illegal as far as the reader is concerned.

It's valid to have an instance of clojure.lang.Keyword with a space in its name. (clojure.core/with-out-str (clojure.core/pr (clojure.core/keyword "A valid keyword"))) => ":A valid keyword" So, it seems like clojure.core/pr and clojure.core/read-string disagree about EDN. Is EDN formally specified? https://github.com/edn-format/edn/issues/56 seems to suggest it is not. I ran into this problem using ptaoussanis/sente to pass EDN over a websocket. The EDN contained a keyword with a space in it, and the clojure(jvm) part of sente had no problem serializing it, but the ClojureScript part of sente barfed on it. I thought it was a bug in sente, however sente simply calls clojure.core/pr to do the serialization... so I played with pr vs read-string and found that they disagree. The serialization that clojure.core/pr does on a keyword with a space in it seems broken to me: user> (clojure.core/with-out-str (clojure.core/pr {:onekey 1 (clojure.core/keyword "two key") 2})) "{:onekey 1, :two key 2}" There doesn't seem to be any way to parse that unambiguously. I think this is a bug. What do you think? https://github.com/ptaoussanis/sente/issues/251 -- You received this message because you are subscribed to the Google Groups "Clojure" group.
