deep-mergeclj
(deep-merge & vals)Recursively merges maps. If vals are not maps, the last value wins.
Recursively merges maps. If vals are not maps, the last value wins.
do1clj/smacro
(do1 form-1 & other-forms)Evaluates all the forms and returns the result of the first form.
Evaluates all the forms and returns the result of the first form.
do2clj/smacro
(do2 form-1 form-2 & other-forms)Evaluates all the forms and returns the result of the second form.
Evaluates all the forms and returns the result of the second form.
econdclj/smacro
(econd & clauses)Like cond, except throws a RuntimeException if no clause matches.
Like `cond`, except throws a RuntimeException if no clause matches.
indexedclj
(indexed s)Returns a lazy sequence of [index, item] pairs, where items come from 's' and indexes count up from zero. eg: (indexed '(a b c d)) => ([0 a] [1 b] [2 c] [3 d])
Returns a lazy sequence of [index, item] pairs, where items come
from 's' and indexes count up from zero.
eg:
(indexed '(a b c d)) => ([0 a] [1 b] [2 c] [3 d])positionsclj
(positions pred coll)Returns a lazy sequence containing the positions at which pred is true for items in coll.
Returns a lazy sequence containing the positions at which pred is true for items in coll.
select-keys-recursivelyclj
(select-keys-recursively m key-paths)Similar to select-keys, but with key paths digging in to a nested map.
key-paths is a sequence. Each element of key-paths begins with a key, k,
to be selected and is followed by a vector of key paths that specify the
things to be selected from the value corresponding to k.
Example:
(select-keys-recursively {:k-1 "v-1"
:k-2 {:k-2-1 "v-2-1"
:k-2-2 {:k-2-2-1 "v-2-2-1"
:k-2-2-2 "v-2-2-2"
:k-2-2-3 "v-2-2-3"}}
:k-3 "v-3"}
[[:k-1]
[:k-2 [:k-2-2
[:k-2-2-1]
[:k-2-2-3]]]])
=> {:k-1 "v-1"
:k-2 {:k-2-2 {:k-2-2-1 "v-2-2-1"
:k-2-2-3 "v-2-2-3"}}}
Similar to `select-keys`, but with key paths digging in to a nested map.
`key-paths` is a sequence. Each element of `key-paths` begins with a key, k,
to be selected and is followed by a vector of key paths that specify the
things to be selected from the value corresponding to k.
Example:
(select-keys-recursively {:k-1 "v-1"
:k-2 {:k-2-1 "v-2-1"
:k-2-2 {:k-2-2-1 "v-2-2-1"
:k-2-2-2 "v-2-2-2"
:k-2-2-3 "v-2-2-3"}}
:k-3 "v-3"}
[[:k-1]
[:k-2 [:k-2-2
[:k-2-2-1]
[:k-2-2-3]]]])
=> {:k-1 "v-1"
:k-2 {:k-2-2 {:k-2-2-1 "v-2-2-1"
:k-2-2-3 "v-2-2-3"}}}transitive-closureclj
(transitive-closure f v)The set of values obtained by starting with v, then applying f to v, then applying f to each of the results, and so on. v and all intermediate values are included in the result.
The set of values obtained by starting with v, then applying f to v, then applying f to each of the results, and so on. v and all intermediate values are included in the result.
transitive-closure-excluding-selfclj
(transitive-closure-excluding-self f v)The set of values obtained by applying f to v, then applying f to each of the results, and so on. All intermediate values are included in the result.
The set of values obtained by applying f to v, then applying f to each of the results, and so on. All intermediate values are included in the result.
unchunkclj
(unchunk s)Produce a fully-lazy sequence from s.
Sometimes Clojure sequences are not fully lazy.
