SpecVersion is the latest fully supported spec version of semver

Functions

func FinalizeVersion 

func FinalizeVersion(s string) (string, error)

FinalizeVersion returns the major, minor and patch number only and discards prerelease and build number.

func NewBuildVersion 

func NewBuildVersion(s string) (string, error)

NewBuildVersion creates a new valid build version

func Sort 

func Sort(versions []Version)

Sort sorts a slice of versions

Types

type PRVersion 

type PRVersion struct {
	VersionStr string
	VersionNum uint64
	IsNum      bool
}

PRVersion represents a PreRelease Version

func NewPRVersion 

func NewPRVersion(s string) (PRVersion, error)

NewPRVersion creates a new valid prerelease version

func (PRVersion) Compare 

func (v PRVersion) Compare(o PRVersion) int

Compare compares two PreRelease Versions v and o: -1 == v is less than o 0 == v is equal to o 1 == v is greater than o

func (PRVersion) IsNumeric 

func (v PRVersion) IsNumeric() bool

IsNumeric checks if prerelease-version is numeric

func (PRVersion) String 

func (v PRVersion) String() string

PreRelease version to string

type Range 

type Range func(Version) bool

Range represents a range of versions. A Range can be used to check if a Version satisfies it: 

range, err := semver.ParseRange(">1.0.0 <2.0.0")
range(semver.MustParse("1.1.1") // returns true

func MustParseRange 

func MustParseRange(s string) Range

MustParseRange is like ParseRange but panics if the range cannot be parsed.

func ParseRange 

func ParseRange(s string) (Range, error)

ParseRange parses a range and returns a Range. If the range could not be parsed an error is returned.

Valid ranges are:

  • "<1.0.0"
  • "<=1.0.0"
  • ">1.0.0"
  • ">=1.0.0"
  • "1.0.0", "=1.0.0", "==1.0.0"
  • "!1.0.0", "!=1.0.0"

A Range can consist of multiple ranges separated by space: Ranges can be linked by logical AND:

  • ">1.0.0 <2.0.0" would match between both ranges, so "1.1.1" and "1.8.7" but not "1.0.0" or "2.0.0"
  • ">1.0.0 <3.0.0 !2.0.3-beta.2" would match every version between 1.0.0 and 3.0.0 except 2.0.3-beta.2

Ranges can also be linked by logical OR:

  • "<2.0.0 || >=3.0.0" would match "1.x.x" and "3.x.x" but not "2.x.x"

AND has a higher precedence than OR. It's not possible to use brackets.

Ranges can be combined by both AND and OR

  • `>1.0.0 <2.0.0 || >3.0.0 !4.2.1` would match `1.2.3`, `1.9.9`, `3.1.1`, but not `4.2.1`, `2.1.1`

func (Range) AND 

func (rf Range) AND(f Range) Range

AND combines the existing Range with another Range using logical AND.

func (Range) OR 

func (rf Range) OR(f Range) Range

OR combines the existing Range with another Range using logical OR.

type Version 

type Version struct {
	Major uint64
	Minor uint64
	Patch uint64
	Pre   []PRVersion
	Build []string //No Precedence
}

Version represents a semver compatible version

func Make 

func Make(s string) (Version, error)

Make is an alias for Parse, parses version string and returns a validated Version or error

func MustParse 

func MustParse(s string) Version

MustParse is like Parse but panics if the version cannot be parsed.

func New 

func New(s string) (*Version, error)

New is an alias for Parse and returns a pointer, parses version string and returns a validated Version or error

func Parse 

func Parse(s string) (Version, error)

Parse parses version string and returns a validated Version or error

func ParseTolerant 

func ParseTolerant(s string) (Version, error)

ParseTolerant allows for certain version specifications that do not strictly adhere to semver specs to be parsed by this library. It does so by normalizing versions before passing them to Parse(). It currently trims spaces, removes a "v" prefix, adds a 0 patch number to versions with only major and minor components specified, and removes leading 0s.

func (Version) Compare 

func (v Version) Compare(o Version) int

Compare compares Versions v to o: -1 == v is less than o 0 == v is equal to o 1 == v is greater than o

func (Version) EQ 

func (v Version) EQ(o Version) bool

EQ checks if v is equal to o.

func (Version) Equals 

func (v Version) Equals(o Version) bool

Equals checks if v is equal to o.

func (Version) FinalizeVersion 

func (v Version) FinalizeVersion() string

FinalizeVersion discards prerelease and build number and only returns major, minor and patch number.

func (Version) GE 

func (v Version) GE(o Version) bool

GE checks if v is greater than or equal to o.

func (Version) GT 

func (v Version) GT(o Version) bool

GT checks if v is greater than o.

func (Version) GTE 

func (v Version) GTE(o Version) bool

GTE checks if v is greater than or equal to o.

func (*Version) IncrementMajor 

func (v *Version) IncrementMajor() error

IncrementMajor increments the major version

func (*Version) IncrementMinor 

func (v *Version) IncrementMinor() error

IncrementMinor increments the minor version

func (*Version) IncrementPatch 

func (v *Version) IncrementPatch() error

IncrementPatch increments the patch version

func (Version) LE 

func (v Version) LE(o Version) bool

LE checks if v is less than or equal to o.

func (Version) LT 

func (v Version) LT(o Version) bool

LT checks if v is less than o.

func (Version) LTE 

func (v Version) LTE(o Version) bool

LTE checks if v is less than or equal to o.

func (Version) MarshalJSON 

func (v Version) MarshalJSON() ([]byte, error)

MarshalJSON implements the encoding/json.Marshaler interface.

func (Version) NE 

func (v Version) NE(o Version) bool

NE checks if v is not equal to o.

func (*Version) Scan 

func (v *Version) Scan(src interface{}) (err error)

Scan implements the database/sql.Scanner interface.

func (Version) String 

func (v Version) String() string

Version to string

func (*Version) UnmarshalJSON 

func (v *Version) UnmarshalJSON(data []byte) (err error)

UnmarshalJSON implements the encoding/json.Unmarshaler interface.

Versions represents multiple versions.

func (Versions) Len 

func (s Versions) Len() int

Len returns length of version collection

func (Versions) Less 

func (s Versions) Less(i, j int) bool
