go-mvn-version
A Go library for parsing maven(java) package versions
go-mvn-version is a library for parsing and comparing versions
The implementation is based on this specification
other reference: maven implementation
Installation and Usage
Installation can be done with a normal go get:
$ go get github.com/masahiro331/go-mvn-version
Version Parsing and Comparison
import "github.com/masahiro331/go-mvn-version"
v1, err := version.NewVersion("10-snapshot")
v2, err := version.NewVersion("10-b1")
if v1.GreaterThan(*v2) {
fmt.Printf("%s is greater than %s", v1, v2)
}
WARNING
This implementation based on the maven specification, but not the maven implementation.
See issues: ComparableVersion incorrectly parses certain version strings
$ go test .

Types ¶
type Comparer ¶
func NewComparer ¶
type Constraints ¶
type Constraints struct {
// contains filtered or unexported fields
}
Constraints is one or more constraint that a version can be checked against.
func NewConstraints ¶
func NewConstraints(v string) (Constraints, error)

type ListItemStack []ListItem
func (*ListItemStack) IsEmpty ¶
func (s *ListItemStack) IsEmpty() bool
IsEmpty checks if stack is empty
func (*ListItemStack) Pop ¶
func (s *ListItemStack) Pop() ListItem
Pop removes and returns top element of stack. Return false if stack is empty.
func (*ListItemStack) Push ¶
func (s *ListItemStack) Push(item ListItem)
Push pushes a new value onto the stack
type Requirements ¶
type Requirements struct {
// contains filtered or unexported fields
}
func NewRequirements ¶
func NewRequirements(v string) (Requirements, error)
NewRequirements is return Requirement [1.0.0], [1.0.1] => []requirement{"[1.0.0]","[1.0.1]"} [1.0.0] => []requirement{"[1.0.0]"}
