Functions

func Compare

func Compare(ver1 string, op Operation, ver2 string) (bool, error)

Compare compare ver1 and ver2 by operation

For example:

Compare(ver1, Greater, ver2) is same as "ver1 > ver2"

Dirty versions and pre versions are regarded as standard version. For example: 'v5.1.2-dev' and 'v5.1.2-betav1' are regarded as 'v5.1.2'.

Latest, nightly or master version is larger than any version

func CompareByStr

func CompareByStr(ver1, opstr, ver2 string) (bool, error)

CompareByStr compare ver1 and ver2

For example:

CompareByStr(ver1, ">", ver2) is same as "ver1 > ver2"

Dirty versions and pre versions are regarded as standard version. For example: 'v5.1.2-dev' and 'v5.1.2-betav1' are regarded as 'v5.1.2'.

Latest, nightly or master version is larger than any version

Types

type Constraint

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

func NewConstraint

func NewConstraint(op Operation, version string) (*Constraint, error)

func (*Constraint) Check

func (c *Constraint) Check(version string) (bool, error)

Check tests if a version satisfies the constraints.

Dirty versions and pre versions are regarded as standard version. For example: 'v5.1.2-dev' and 'v5.1.2-betav1' are regarded as 'v5.1.2'.

Latest, nightly or master version is larger than any version

type Operation

type Operation string

const (
	Greater        Operation = ">"
	GreaterOrEqual Operation = ">="
	Less           Operation = "<"
	LessOrEqual    Operation = "<="
)
