peschke.collections.TakeUntil.syntax._

Provides TraversibleLike#takeUntil, which is alternative to TraversibleLike#takeWhile. The most useful distinction between the two is how the final value is handled.

assert((0 to 10).toList.takeWhile(_ != 5) == List(0, 1, 2, 3, 4))
assert((0 to 10).toList.takeUntil(_ == 5) == List(0, 1, 2, 3, 4, 5))

peschke.collections.range.syntax._

Provides utility methods for manipulating Range and NumericRange.

• grow :: This extends a range such that (ignoring underflow) range.grow(n).drop(n) == range
• growRight :: This extends a range such that (ignoring overflow) range.growRight(n).dropRight(n) == range
• shift :: This shifts a range towards Int.MaxValue by a multiple of the range step
• unshift :: This shifts a range towards Int.MinValue by a multiple of the range step
• sliceRange :: This specialization of NumericRange#slice returns a NumericRange instead of an IndexedSeq
