package sortorder

import "github.com/fvbommel/sortorder"

Package sortorder implements sort orders and comparison functions.

Currently, it only implements so-called "natural order", where integers embedded in strings are compared by value.

Functions ¶

func NaturalLess ¶

func NaturalLess(str1, str2 string) bool

NaturalLess compares two strings using natural ordering. This means that e.g. "abc2" < "abc12".

Non-digit sequences and numbers are compared separately. The former are compared bytewise, while digits are compared numerically (except that the number of leading zeros is used as a tie-breaker, so e.g. "2" < "02")

Limitation: only ASCII digits (0-9) are considered.

Types ¶

type Natural ¶

type Natural []string

Natural implements sort.Interface to sort strings in natural order. This means that e.g. "abc2" < "abc12".

Non-digit sequences and numbers are compared separately. The former are compared bytewise, while digits are compared numerically (except that the number of leading zeros is used as a tie-breaker, so e.g. "2" < "02")

Limitation: only ASCII digits (0-9) are considered.

func (Natural) Len ¶

func (n Natural) Len() int

func (Natural) Less ¶

func (n Natural) Less(i, j int) bool

func (Natural) Swap ¶

func (n Natural) Swap(i, j int)
