Overview

Package sortutil provides methods for sorting slices

Index

• func NaturalLess(s1, s2 string) bool
• func Strings(s []string, caseInsensitive bool)
• func StringsNatural(a []string)
• func VersionCompare(v1, v2 string) bool
• func Versions(s []string)

Examples

• Strings
• Versions

Functions

func NaturalLess

func NaturalLess(s1, s2 string) bool

NaturalLess compares two strings using natural ordering. This means that e.g. "abc2" < "abc12" This code based on sortorder package created by @fvbommel

func Strings

func Strings(s []string, caseInsensitive bool)

Strings sorts strings slice and support case insensitive mode

Example

stringSlice := []string{
	"Alisa",
	"Luna",
	"remedios",
	"Ona",
	"Eugene",
	"lorriane",
	"Zachariah",
	"cecily",
	"eleonora",
	"Dotty",
}

// Case insensitive sorting
Strings(stringSlice, false)

fmt.Println(stringSlice)

// Case sensitive sorting
Strings(stringSlice, true)

fmt.Println(stringSlice)

Output:

[Alisa Dotty Eugene Luna Ona Zachariah cecily eleonora lorriane remedios]
[Alisa cecily Dotty eleonora Eugene lorriane Luna Ona remedios Zachariah]

func StringsNatural

func StringsNatural(a []string)

StringsNatural sorts a slice of strings in natural order Limitation: only ASCII digits (0-9) are considered.

func VersionCompare

func VersionCompare(v1, v2 string) bool

VersionCompare compares 2 versions and returns true if v1 less v2. This function can be used for version sorting with structs

func Versions

func Versions(s []string)

Versions sorts versions slice

Example

versionSlice := []string{
	"2.0-5",
	"1.3b",
	"1.1",
	"1.3",
	"1.1.6",
	"1",
	"2.0",
	"2.0-1",
}

Versions(versionSlice)

fmt.Println(versionSlice)

Output:

[1 1.1 1.1.6 1.3 1.3b 2.0 2.0-1 2.0-5]
