The raw regular expression string used for testing the validity of a version.

type Collection

type Collection []*Version

Collection is a type that implements the sort.Interface interface so that versions can be sorted.

func (Collection) Len

func (v Collection) Len() int

func (Collection) Less

func (v Collection) Less(i, j int) bool

func (Collection) Swap

func (v Collection) Swap(i, j int)

type Constraint

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

Constraint represents a single constraint for a version, such as ">= 1.0".

func (*Constraint) Check

func (c *Constraint) Check(v *Version) bool

Check tests if a constraint is validated by the given version.

func (*Constraint) String

func (c *Constraint) String() string

type Constraints

type Constraints []*Constraint

Constraints is a slice of constraints. We make a custom type so that we can add methods to it.

func NewConstraint

func NewConstraint(v string) (Constraints, error)

NewConstraint will parse one or more constraints from the given constraint string. The string must be a comma-separated list of constraints.

func (Constraints) Check

func (cs Constraints) Check(v *Version) bool

Check tests if a version satisfies all the constraints.

func (Constraints) MarshalJSON

func (c Constraints) MarshalJSON() ([]byte, error)

MarshalJSON implements the json.Marshaller interface.

func (Constraints) String

func (cs Constraints) String() string

Returns the string format of the constraints

func (*Constraints) UnmarshalJSON

func (c *Constraints) UnmarshalJSON(value []byte) error

UnmarshalJSON implements the json.Unmarshaller interface.

type Mutator

type Mutator struct {
	*Version
}

func (*Mutator) Done

func (m *Mutator) Done() *Version

func (*Mutator) NextMajor

func (m *Mutator) NextMajor() *Mutator

func (*Mutator) NextMinor

func (m *Mutator) NextMinor() *Mutator

func (*Mutator) NextPatch

func (m *Mutator) NextPatch() *Mutator

func (*Mutator) ResetMetadata

func (m *Mutator) ResetMetadata() *Mutator

func (*Mutator) ResetPatch

func (m *Mutator) ResetPatch() *Mutator

func (*Mutator) ResetPrerelease

func (m *Mutator) ResetPrerelease() *Mutator

func (*Mutator) SetMetadata

func (m *Mutator) SetMetadata(md string) *Mutator

func (*Mutator) SetPrerelease

func (m *Mutator) SetPrerelease(id string) *Mutator

type Version

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

Version represents a single version.

func Must

func Must(v *Version, err error) *Version

Must is a helper that wraps a call to a function returning (*Version, error) and panics if error is non-nil.

func NewSemver

func NewSemver(v string) (*Version, error)

NewSemver parses the given version and returns a new Version that adheres strictly to SemVer specs https://semver.org/

func NewVersion

func NewVersion(v string) (*Version, error)

NewVersion parses the given version and returns a new Version.

func (*Version) Clone

func (v *Version) Clone() *Version

func (*Version) Compare

func (v *Version) Compare(other *Version) int

Compare compares this version to another version. This returns -1, 0, or 1 if this version is smaller, equal, or larger than the other version, respectively.

If you want boolean results, use the LessThan, Equal, GreaterThan, GreaterThanOrEqual or LessThanOrEqual methods.

func (*Version) Equal

func (v *Version) Equal(o *Version) bool

Equal tests if two versions are equal.

func (*Version) GreaterThan

func (v *Version) GreaterThan(o *Version) bool

GreaterThan tests if this version is greater than another version.

func (*Version) GreaterThanOrEqual

func (v *Version) GreaterThanOrEqual(o *Version) bool

GreaterThanOrEqual tests if this version is greater than or equal to another version.

func (*Version) LessThan

func (v *Version) LessThan(o *Version) bool

LessThan tests if this version is less than another version.

func (*Version) LessThanOrEqual

func (v *Version) LessThanOrEqual(o *Version) bool

LessThanOrEqual tests if this version is less than or equal to another version.

func (*Version) Major

func (v *Version) Major() int64

Major returns major version number of this Version object

func (Version) MarshalJSON

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

MarshalJSON implements the json.Marshaller interface.

func (*Version) Metadata

func (v *Version) Metadata() string

Metadata returns any metadata that was part of the version string.

Metadata is anything that comes after the "+" in the version. For example, with "1.2.3+beta", the metadata is "beta".

func (*Version) Minor

func (v *Version) Minor() int64

Minor returns minor version number of this Version object

func (*Version) Original

func (v *Version) Original() string

Original returns the original parsed version as-is, including any potential whitespace, `v` prefix, etc.

func (*Version) Patch

func (v *Version) Patch() int64

Patch returns patch version number of this Version object

func (*Version) Prerelease

func (v *Version) Prerelease() string

Prerelease returns any prerelease data that is part of the version, or blank if there is no prerelease data.

Prerelease information is anything that comes after the "-" in the version (but before any metadata). For example, with "1.2.3-beta", the prerelease information is "beta".

func (*Version) Segments

func (v *Version) Segments() []int

Segments returns the numeric segments of the version as a slice of ints.

This excludes any metadata or pre-release information. For example, for a version "1.2.3-beta", segments will return a slice of 1, 2, 3.

func (*Version) Segments64

func (v *Version) Segments64() []int64

Segments64 returns the numeric segments of the version as a slice of int64s.

This excludes any metadata or pre-release information. For example, for a version "1.2.3-beta", segments will return a slice of 1, 2, 3.

func (*Version) String

func (v *Version) String() string

String returns the full version string included pre-release and metadata information.

This value is rebuilt according to the parsed segments and other information. Therefore, ambiguities in the version string such as prefixed zeroes (1.04.0 => 1.4.0), `v` prefix (v1.0.0 => 1.0.0), and missing parts (1.0 => 1.0.0) will be made into a canonicalized form as shown in the parenthesized examples.

func (*Version) ToMutator

func (v *Version) ToMutator() *Mutator

func (*Version) UnmarshalJSON

func (v *Version) UnmarshalJSON(value []byte) error

UnmarshalJSON implements the json.Unmarshaller interface.
