assoc-ifclj/s

(assoc-if map key val)
(assoc-if map key val pred)

Conditionally assoc val into map at key if val passes the test specified by the optional pred. If pred is not specified, the val is tested for truthiness.

Conditionally assoc `val` into `map` at `key` if `val` passes the test
specified by the optional `pred`. If `pred` is not specified, the val is
tested for truthiness.

compactclj/s

(compact m)

Returns 'm' with all the keys that have nil or empty values removed. If the act of compaction results in all keys being removed a nil is returned.

The compaction is recursive, e.g., (compact {:a {:b [{} {:c {}}]}}) => nil

Returns 'm' with all the keys that have nil or empty values removed.

deep-merge-withclj/s

(deep-merge-with f & maps)

Like merge-with, but merges 'maps' recursively, applying 'f' only when there is a non-map at a particular level. (deep-merge-with + {:a {:b {:c 1 :d {:x 1 :y 2}} :e 3} :f 4} {:a {:b {:c 2 :d {:z 9} :z 3} :e 100}}) => {:a {:b {:z 3, :c 3, :d {:z 9, :x 1, :y 2}}, :e 103}, :f 4}
