What's New

ToJson Protocol

Custom serialization support via the ToJson protocol:

(defrecord Person [first-name last-name]
  ToJson
  (-to-json [_]
    {:name (str first-name " " last-name)}))

(toon/encode (->Person "Alice" "Smith"))
;; => "name: Alice Smith"

Replacer Function

Transform values during encoding with a replacer function:

(toon/encode data {:replacer (fn [k v] (if (= k "password") "***" v))})

Path Expansion with Quoted Keys

Path expansion now correctly tracks and quotes keys that require quoting.

JSON-like Numeric Grammar

• Leading zeros now rejected (007, -007 → treated as strings)
• Scientific notation supported (1e10, 1E-5, 2.5e+3)

Bare List Marker Support

Bare list markers (- alone) now decode to empty objects {}:

[2]:
  -
  - name: Ada

Decodes to: [{} {"name" "Ada"}]

V3.0 Spec: List-Item Tabular Arrays

Enhanced encoding for arrays of objects within list items.
