Print namespaced maps using #:

Yep, I had this thought too after the 1.9 upgrade. The pretty printer should definitely support this. I'm not sure that adding it to the canonical printer is a good idea, since the keyword dispatch is Clojure reader sugar and not present in the EDN spec.

Ah. You're right that it isn't in the EDN spec, though oddly, the Clojure EDN reader does accept it:

user=> (clojure.edn/read-string "#:a{:b 1}")
{:a/b 1}

to avoid generating too much horizontal whitespace, I'd suggest that the prefix sometimes or always go on its own line.

[aengelberg]

I think that would make sense if and only if the data inside the map spanned multiple lines.

[gfredericks]

agreed; I will retroactively have meant that by the word "sometimes"

[gfredericks]

although you could argue that if you have a maximally-long-single-lined-map that needs to be prefixed by a very long namespace, doing two lines is better

and perhaps I will argue that

Sounds good to me - fipp should handle the line-breaking when the total line size exceeds a certain amount.
