ArrIter type

Arr (array) iterator.

Example

my_args = %[--switch val some other positional --sw2 val2]
i = Iter(my_args)

named = {}
positional = []

while i {
	t = i.next()
	m = t ~ Pfx('--')
	if m {
		named[m.after] = i.next()
	} else {
		positional.push(t)
	}
}

echo(named)
echo(positional)
# Output:
#   {switch=val, sw2=val2}
#   [some,other,positional]

Methods

Bool(i:ArrIter) Source: autoload/Iter.ngs:306: Check whether there are more array elements to iterate over.
Returns
Bool. true: next() will return next element. false: next() will throw NoNext

init(i:ArrIter, arr:Arr) Source: autoload/Iter.ngs:296

ArrIter constructor.

Example

i = ArrIter([10, 20, 30])

next(i:ArrIter) Source: autoload/Iter.ngs:311: Get value of the next element of the array iterated over.
Returns
Any

peek(i:ArrIter) Source: autoload/Iter.ngs:321: Preview value of the next element of the array iterated over. Does not affect internal pointer which means it does not affect of value returned by next().
Returns
Any

Str(i:ArrIter) Source: autoload/Iter.ngs:302: Textual representation of ArrIter.
Returns
Str
