Examples
Given deps.edn:
{:deps {foo {:mvn/version "0.1.0"}
bar {:mvn/version "0.2.0"}
;; here's a comment and the next dep is ignored:
#_baz #_{:mvn/version "0.3.0"}}}and this script:
(require '[borkdude.rewrite-edn :as r])
(def edn-string (slurp "deps.edn"))
(def nodes (r/parse-string edn-string))Add dependency
(println (str (r/assoc-in nodes [:deps 'my-other-dep] {:mvn/version "0.1.2"}))){:deps {foo {:mvn/version "0.1.0"}
bar {:mvn/version "0.2.0"}
;; here's a comment and the next dep is ignored:
#_baz #_{:mvn/version "0.3.0"}
my-other-dep {:mvn/version "0.1.2"}}}Fully qualify dep symbols
(defn qualify-sym-node [sym-node]
(let [sym (r/sexpr sym-node)]
(if (or (not (symbol? sym))
(qualified-symbol? sym))
sym-node
(symbol (str sym) (str sym)))))
(def updated-nodes (r/update nodes :deps #(r/map-keys qualify-sym-node %)))
(println (str updated-nodes)){:deps {foo/foo {:mvn/version "0.1.0"}
bar/bar {:mvn/version "0.2.0"}
;; here's a comment and the next dep is ignored:
#_baz #_{:mvn/version "0.3.0"}}}Also see examples.
