Functions ¶

func Compare ¶

func Compare(a, b Version) int

Compare returns -1, 0, or 1 by npm semver precedence (build ignored).

func MaxSatisfying ¶

func MaxSatisfying(versions []string, rangeInput string) string

MaxSatisfying returns the highest version matching the range, or "".

func Satisfies ¶

func Satisfies(version string, rangeInput string) bool

Satisfies applies npm's rule that prerelease versions only match ranges whose comparator set names a prerelease on the same [major,minor,patch].

func Valid ¶

func Valid(input string) bool

Valid reports whether input is an exact version (npm semver.valid).

func ValidRange ¶

func ValidRange(input string) bool

ValidRange reports whether input parses as an npm range.

Types ¶

type Range ¶

type Range struct {
	// contains filtered or unexported fields
}

Range is a parsed npm range: OR of comparator sets.

func ParseRange ¶

func ParseRange(input string) (Range, bool)

func (Range) Matches ¶

func (r Range) Matches(v Version) bool

type Version ¶

type Version struct {
	Major, Minor, Patch int
	Prerelease          []string
}

func Parse ¶

func Parse(input string) (Version, bool)

Parse accepts an exact npm version ("1.2.3", "v1.2.3", "1.2.3-rc.1+build").
