Edamame: configurable EDN and Clojure parser with location metadata and more

1.4.25

• Support new ^[String] metadata notation which desugars into ^{:param-tags [String]}

1.4.24

• Add :map and :set options to coerce map/set literals into customizable data structures, for example, an ordered collections to preserve key order.

(require '[edamame.core :as e])
(require '[flatland.ordered.map :as m])
(e/parse-string "{:a 1}" {:map m/ordered-map}) ;;=> #ordered/map ([:a 1])
(require '[clojure.data.json :as j])
(j/write-str (e/parse-string "{:a 1 :b 2 :c 3 :d 4 :e 5 :f 6 :g 7 :h 8 :i 9 :j 10 :k 11 :l 12}" {:map m/ordered-map}))
;;=> "{\"a\":1,\"b\":2,\"c\":3,\"d\":4,\"e\":5,\"f\":6,\"g\":7,\"h\":8,\"i\":9,\"j\":10,\"k\":11,\"l\":12}"

Breaking changes

0.0.12

• Revert #70, instead return cljs.tagged-literals/JSValue object which should be evaluated manually.

0.0.10

• Function literals now expand into a call to fn* instead of fn

0.0.8

• Options to tools.reader, like :readers for passing reader tag functions, now have to be passed as :tools.reader/opts in the options.
• The :dispatch option has been deprecated. It still works in 0.0.8 but is now undocumented and planned to be removed in a future version.
