assoc-ifclj/s
(assoc-if m k v)(assoc-if m k v & kvs)Like assoc, but noop if v is falsy.
Like assoc, but noop if v is falsy.
coll-append-at-head?clj/s
(coll-append-at-head? s)Return true if column add items at head with conj.
Return true if column add items at head with conj.
collection?clj/s
(collection? x)Returns true for sequential collections and sets, false for maps.
Returns true for sequential collections and sets, false for maps.
conj-at-indexclj/s
(conj-at-index v idx x)Add element to a vector at some specific index. Only works with vectors!
Add element to a vector at some specific index. Only works with vectors!
dedupe-byclj/s
(dedupe-by f)(dedupe-by f coll)Returns a lazy sequence removing consecutive duplicates in coll when passed to a function f. Returns a transducer when no collection is provided.
Returns a lazy sequence removing consecutive duplicates in coll when passed to a function f. Returns a transducer when no collection is provided.
deep-mergeclj/s≠
(deep-merge & maps)(deep-merge)(deep-merge a)(deep-merge a b)(deep-merge a b & more)Recursively merges maps together. If all the maps supplied have nested maps
under the same keys, these nested maps are merged. Otherwise the value is
overwritten, as in clojure.core/merge.
Copied from Medley library.

distinct-byclj/s
(distinct-by f)(distinct-by f coll)Returns a lazy sequence of the elements of coll, removing any elements that return duplicate values when passed to a function f.
Returns a lazy sequence of the elements of coll, removing any elements that return duplicate values when passed to a function f.
find-firstclj/s
(find-first f coll)Return the first element in coll that returns true for f.
Return the first element in coll that returns true for f.
index-byclj/s
(index-by f coll)Like group by, but will keep only the last result.
Like group by, but will keep only the last result.
index-ofclj/s
(index-of coll x)Find the index of element x in coll. Return nil if element is not found.
Find the index of element x in coll. Return nil if element is not found.
iterate-whileclj/s
(iterate-while f x)Like iterate, but stops when it sees a nil value.
Like iterate, but stops when it sees a `nil` value.
iteratorclj/s
(iterator coll)CLJC utility to get an iterator from the collection.
CLJC utility to get an iterator from the collection.
keys-setclj/s
(keys-set m)Return the map keys, as a set. This also checks if the entry is a map, otherwise returns nil (instead of throw).
Return the map keys, as a set. This also checks if the entry is a map, otherwise returns nil (instead of throw).
make-map-entryclj/s
(make-map-entry k v)CLJC helper to create MapEntry.

Example: (map-keys #(str/replace (name %) "_" "-") {"foo_bar" 1}) => {"foo-bar" 1}
Map over the given hash-map keys.
Example:
(map-keys #(str/replace (name %) "_" "-") {"foo_bar" 1}) => {"foo-bar" 1}
map-valsclj/s
(map-vals f m)Map over the given hash-map vals.
Example: (map-vals inc {:a 1 :b 2})
Map over the given hash-map vals.
Example:
(map-vals inc {:a 1 :b 2})
merge-defaultsclj/s
(merge-defaults m defaults)Like merge, but only add keys that are not present in the original map.
Like merge, but only add keys that are not present in the original map.
merge-growclj/s
(merge-grow)(merge-grow a)(merge-grow a b)Additive merging.
When merging maps, it does a deep merge. When merging sets, makes a union of them.
When value of the right side is nil, the left side will be kept.
For the rest works as standard merge.

restore-orderclj/s
(restore-order inputs key items)(restore-order inputs key items default-fn)Sorts output list to match input list order.
Sorts output list to match input list order.
update-containedclj/s
(update-contained m k f)(update-contained m k f a1)(update-contained m k f a1 a2)(update-contained m k f a1 a2 a3)(update-contained m k f a1 a2 a3 & args)Update some key when that key is present in the map.
