flat->tree clj

(flat->tree separator row)

Transforms a flat associative array (map) to a nested structure so that all values are associated to a new nested or existing map using a specific key path, which is generated from the current key of the value.

A key path is a sequence of keys and it is generated from splitting the current key using a given separator. Separator is a regular expression.

e.g. {:a_x 1, :a_y 2 :b 3} -> {a: {:x 1 :y 2} :b 3}

key-path clj

(key-path key separator)

Split key to a key path. Key path item separator is separator regular expression.

sequence->map clj

(sequence->map object)

When sequences are part of the nested structure they can be first converted to maps and then to flat objects using function tree->flat.

tree->flat clj

(tree->flat separator object)

(tree->flat prefix separator object)

Transforms a nested associative array (map) to a flat one. This is an inverse of the flat->tree function.

The nested structure is not allowed to contain cycles it must be a tree.

If nested structure contains also other sequences they can be first converted to map using function sequence->map
