Deterministic parse and generate

[AndreaCrotti]

Is there any possible way to make something like that work?
I have massive JSON files (on single lines so no spacing issues) and for annoying reasons, I have to regenerate exactly the same thing after I parse it.
It works more or less randomly, but I sometimes get the keys in the maps in a different order, is there any way to make that deterministic?

(def obj (cheshire.core/parse-string (slurp "myfile.json")))
(def full-string (slurp "myfile.json"))
(= full-string (cheshire.core/generate-string obj)) ;; false

It's probably just because parsing will generate non sorted maps, is there any way to make Cheshire use sorted maps?

I just tried one little change #207
but unfortunately that's not enough, it still does not work

I have a bit similar use-case. I'm using cheshire for pretty-printing JSON.

So I'm reading the JSON from file and then using parse-stream and generate-string with pretty printing options, and the end result is a pretty printed JSON file but the order of the keys is changed. Would be nice if there was an option in Cheshire to keep the order of the keys.
