sliceutils

Nimble package for extensions on Slice/HSlice. Features include:

• sliceutils/tuples: indexing tuples by backwards index and by slices of ordinals or backwards indexes
• sliceutils/strides: slice type with custom increments other than 1
• sliceutils/until: slice utility type that counts every element except the last one, made with floats in mind
• sliceutils/intslices: utility procedures for integer slices
  • subscript indexing for integer slices with ordinals, backwards indexes, or slices of ordinals or backwards indexes
  • diff(HSlice[T, U: SomeInteger]): int: the distance between the 2 bounds, has alias abs
• sliceutils/general: procedures for generic slices, examples being
  • to(T, U) -> HSlice[T, U]: alternate constructor for slices
  • swap(HSlice[T, U]) -> HSlice[U, T]: swaps the bounds of the slice
  • sort(Slice[T]) -> Slice[T]: gives the bounds ascending order
  • span(HSlice[T, U]) -> int: alias for system.len as len in this package means "number of results of an iteration"
  • spans(HSlice[T, U], V) -> bool: alias for system.contains as contains in this package means "is one of the given values of an iteration"
  • @(HSlice[T, U]) -> seq: makes seq from slice, iterations must match len

import sliceutils imports all of these modules.

Tests are ran for multiple backends.

Warning: This package overuses the type system a bit and breaks very easily for versions below 1.4.0. Even on 1.4.0, you may come across Nim bugs.
