Manipulation of sequences
concat-atclj/s
(concat-at x kw y)Concatenate sequences x and y, y is inserted at position kw.
If kw not found, y is concatenated at the end of x.
Concatenate sequences `x` and `y`, `y` is inserted at position `kw`. If `kw` not found, `y` is concatenated at the end of `x`.
index-ofclj/s
(index-of coll pred)Find the position of x, the first occurence matching(x) in coll.
Returns its position Params:
collcollection to search inpredpred is a function returning true when called on the element to return the sequence of
Find the position of x, the first occurence matching(x) in coll. Returns its position Params: * `coll` collection to search in * `pred` pred is a function returning true when called on the element to return the sequence of
indexedclj/s
(indexed s)Returns a lazy sequence of [index, item] pairs, where items come from 's' and indexes count up from zero.
(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. (indexed '(a b c d)) => ([0 a] [1 b] [2 c] [3 d])
position-by-valuesclj/s
(position-by-values v)Returns a map which associates each value of the vector to the positions where it happens.
Params:
v
Returns a map which associates each value of the vector to the positions where it happens. Params: * `v`
positionsclj/s
(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.
trim-leading-nilclj/s
(trim-leading-nil aseq)(trim-leading-nil aseq nil-fn)Remove nil values at the end of a sequence Params:
aseqa sequence which will be tested starting from the endnil-fnis the function to test nullity, (defaulted tonil?)
Remove nil values at the end of a sequence Params: * `aseq` a sequence which will be tested starting from the end * `nil-fn` is the function to test nullity, (defaulted to `nil?`)
