json-utils.traversal — json-utils 0.1.3

json-branch? clj/s

(json-branch? form)

True if the form is a branch in a json data structure.

json-children clj/s

(json-children form)

Returns the children of the (json) form.

json-tree-seq clj/s

Provides a tree-seq for json structures.

kv-external-uri? clj/s

(kv-external-uri? form)

prewalk clj/s

(prewalk parent state state-fn replace-fn form)

Like clojure.walk/prewalk but stateful. parent is the parent of the form. state is recursed down through the form, at each level updated by the state-fn (which must accept previous state, the parent form and the current form. replace-fn accepts the current state and form.

replace clj/s

(replace dont-expand expand-levels)

update-st clj/s

(update-st state parent form)

vec? clj/s

(vec? x)

with-path clj/s

(with-path form
           &
           {:keys [expand-levels exceptions]
            :or {exceptions #{} expand-levels 0}})

Decorates a form with :path information at all levels. Excepts either clojure data structures or a json string. :expand-levls is an integer which determines to how many levels down into the form external uri's should (still) be expanded. The default is 0. :exceptions is a set of keywords not to be uri/resolved.

with-path-promise cljs

(with-path-promise form
                   f
                   &
                   {:keys [expand-levels exceptions]
                    :or {exceptions #{} expand-levels 0}})

Same as with path but the first pass through the tree yielded any uncompleted promises, waits until those are resolved. cljs only. f is a completion/callback function to be applied to the fully resolved tree, e.g. to put it into some state, for example an Atom.
