io.randomseed.bankster.util.map
dissoc-in
added in 1.0.0
(dissoc-in m [k & ks :as keys])
Like assoc-in but removes entries. Leaves empty maps.
invert-in-sets
added in 1.0.0
(invert-in-sets m)
(invert-in-sets m dst)
Like clojure.set/map-invert
but preserves all possible values in sets.
lazy-get
macro
added in 1.0.0
(lazy-get m k exp)
Like get but the default value is not evaluated if the key is found.
map-keys
added in 1.0.0
(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
added in 1.0.0
(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
added in 1.0.0
(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
added in 1.0.0
(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
added in 1.0.0
(map-of-vectors-invert-flatten m)
Like clojure.set/map-invert
but for map of vectors (as values). Duplicated keys are replaced.
map-vals
added in 1.0.0
(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
added in 1.0.0
(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
added in 1.0.0
(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
added in 1.0.0
(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
added in 1.0.0
(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
added in 1.0.0
(remove-empty-values m)
(remove-empty-values m only)
Removes entries with empty values from a map.
remove-keys-ns
added in 1.0.2
(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
added in 1.0.0
(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-values
added in 1.0.0
(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
added in 1.0.0
(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.
