Function Documentation

bi_enumerate()

Value bi_enumerate

(

const Value *

arr

)

Build an array of [index, value] pairs from an input array.

For an input array [v0, v1, ...], returns [[0, v0], [1, v1], ...]. Non-array inputs are treated as empty arrays by array_length/array_get_copy.

Ownership: The returned Value owns its internal array; caller must free it with free_value().

Parameters

arr	Input array Value.

Returns

An array Value of length equal to the input's length.

bi_zip()

Value bi_zip	(	const Value *	a,
		const Value *	b )

Zip two arrays into an array of pairs up to the shorter length.

For inputs a=[a0,a1,...], b=[b0,b1,...], returns [[a0,b0],[a1,b1], ...] with length min(len(a), len(b)).

Ownership: The returned Value owns its internal array; caller must free it with free_value().

Parameters

a	First input array Value.
b	Second input array Value.

Returns

Array of pairs as a Value.
