assoc-if clj macro

(assoc-if coll pred k val)

assoc-if-key clj macro

(assoc-if-key coll k pred val)

assoc-if-not clj macro

(assoc-if-not coll pred k val)

assoc-if-not-key clj macro

(assoc-if-not-key coll k pred val)

dissoc-in clj

(dissoc-in m [k & ks :as keys])

Like assoc-in but removes entries. Leaves empty maps.

invert-in-sets clj

(invert-in-sets m)

(invert-in-sets m dst)

Like clojure.set/map-invert but preserves all possible values in sets.

lazy-get clj macro

(lazy-get m k exp)

Like get but the default value is not evaluated if the key is found.

map-keys clj

(map-keys f m)

(map-keys f m dst)

For each key and value of the given map m calls a function passed as the first argument (passing successive keys during calls to it) and generates a map with keys updated by results returned by the function. When the third argument is given then it should be a map on which operations are performed instead of using an empty map.

map-keys-and-vals clj

(map-keys-and-vals f m)

(map-keys-and-vals f m dst)

For each key and value of the given map m calls a function passed as the first argument (passing successive keys during calls to it) and generates a map with keys updated by results returned by the function and values also updated by results of the same function. The function should return a sequential collection of 2 elements: first containing a new value of a key and second containing a new value of a transformed value associated with that key. When the third argument is given then it should be a map on which operations are performed instead of using an empty map.

map-keys-by-v clj

(map-keys-by-v f m)

(map-keys-by-v f m dst)

For each key and value of the given map m calls a function passed as the first argument (passing successive values during calls to it) and generates a map with keys updated by results returned by the function. When the third argument is given then it should be a map on which operations are performed instead of using and empty map.

map-of-sets-invert clj

(map-of-sets-invert m)

Like clojure.set/map-invert but for map of sets (as values) to preserve all possible values (as keys of newly created map).

map-of-vectors-invert-flatten clj

(map-of-vectors-invert-flatten m)

Like clojure.set/map-invert but for map of vectors (as values). Duplicated keys are replaced.

map-vals clj

(map-vals f m)

(map-vals f m dst)

For each key and value of the given map m calls a function passed as the first argument (passing successive values during calls to it) and generates a map with values updated by results returned by the function. When the third argument is given it should be a map on which operations are performed instead of using the original map. This may be helpful when we want to avoid merging the results with another map.

map-vals-by-k clj

(map-vals-by-k f m)

(map-vals-by-k f m dst)

For each key and value of the given map m calls a function passed as the first argument (passing successive keys during calls to it) and generates a map with values updated by results returned by the function. When the third argument is given it should be a map on which operations are performed instead of using the original map. This may be helpful when we want to avoid merging the results with another map.

map-vals-by-kv clj

(map-vals-by-kv f m)

(map-vals-by-kv f m dst)

For each key and value of the given map m calls a function passed as the first argument (passing successive keys and values during calls to it) and generates a map with values updated by results returned by the function. When the third argument is given it should be a map on which operations are performed instead of using the original map. This may be helpful when we want to avoid merging the results with another map.

map-values clj

(map-values f coll)

Recursively transforms values of a coll using function f. The function should take a value and return new value.

remove-by-if-value-in clj

(remove-by-if-value-in m pred only)

Removes map entries if the given predicate returns true and value is in the given set.

remove-empty-values clj

(remove-empty-values m)

(remove-empty-values m only)

Removes entries with empty values from a map.

remove-except clj

(remove-except m keyseq)

remove-if-value clj

(remove-if-value m pred)

remove-if-value-in clj

(remove-if-value-in m vals)

remove-if-value-not-in clj

(remove-if-value-not-in m vals)

remove-keys-ns clj

(remove-keys-ns m)

Removes namespace component from qualified keys (keywords and symbols). Non-qualified identifiers and other data types are not renamed.

update-existing clj

(update-existing coll k fun & more)

Updates the key k of the given collection coll by calling a function fun and passing optional arguments specified as additional arguments. Will not perform any update if the given key does not exist within the collection. Returns a collection.

update-missing clj

(update-missing coll k fun & more)

update-values clj

(update-values map vmap)

(update-values map vmap create-keys?)

Returns the given map with its values identified with keys from vmap updated with the associated functions from vmap.

update-values-recur clj

(update-values-recur map vmap)

(update-values-recur map vmap create-keys?)

Returns the given map with its values identified with keys from vmap recursively updated with the associated functions from vmap. Shape is not reflected, second map (vmap) should be flat, searching for keys is recursive, including nested vectors.
