Clojure sequence operation

Question

How to get a new sequence from an old sequence, the elements of the new one are from the old one until a condition is met

Suppose the condition is #(> % 0)

'(1 2 3 0 3 2 0 1) returns 1, 2, 3

'(0 1 2 3) returns empty seq

'(1 2 3) returns everything.

Note it's not same as filter.

Answer 1

You probably want to use take-while:

(take-while #(> % 0) '(1 2 3 0 3 2 0 1))
=> (1 2 3)
