v1.19.0

added: Diff (#112)

Diff returns the elements that need to be added or removed from the first slice to have the same elements in the second slice.

The order of elements is not taken into consideration, so the slices are treated sets that allow duplicate items.

The added and removed returned may be blank respectively or contain up to as many elements that exist in the largest slice.

Fixes #75

v1.18.0

added: SortStableUsing and SortUsing (#103)

SortStableUsing works similar to sort.SliceStable. However, unlike sort.SliceStable the slice returned will be reallocated as to not modify the input slice.

SortUsing works similar to sort.Slice. However, unlike sort.Slice the slice returned will be reallocated as to not modify the input slice.

v1.17.1

docs: Unique is O(n) (#102)

Fixes #92

v1.17.0

added: Reduce (#106)

Reduce continually applies the provided function over the slice. Reducing the elements to a single value.

Returns a zero value of ElementType if there are no elements in the slice. It will panic if the reducer is nil and the slice has more than one element (required to invoke reduce).

Otherwise returns a ​result of applying reducer from left to right.

Fixes #87

v1.16.0

added: Product (#109)

Product is the product of all of the elements.

Fixes #69

v1.15.0

Intersect (#94)

Updates #72

Rename Select, Unselect and Transform (#89)

See the ​full discussion in #86.

Fixes #86

v1.13.1

Remove circular dependency on `pie/strings_pie.go` (#100)

The file main.go, used to build the pie command and in turn to generate pie/*_pie.go files, references pie/strings_pie.go function Contains. Because there is only one use and the use case is simple, removing the circular dependency allows the generate/re-generation of pie/*_pie.go functions to be generated without already existing. This also covers the edge case of generating pie/strings_pie.go without the Contains function.
