semver for golang [![Build Status](https://drone.io/github.com/blang/semver/status.png)](https://drone.io/github.com/blang/semver/latest) [![GoDoc](https://godoc.org/github.com/blang/semver?status.png)](https://godoc.org/github.com/blang/semver) [![Coverage Status](https://img.shields.io/coveralls/blang/semver.svg)](https://coveralls.io/r/blang/semver?branch=master)
|
||||
======
|
||||
|
||||
semver is a [Semantic Versioning](http://semver.org/) library written in golang. It fully covers spec version `2.0.0`.
|
||||
|
||||
Usage
|
||||
-----
|
||||
```bash
|
||||
$ go get github.com/blang/semver
|
||||
```
|
||||
Note: Always vendor your dependencies or fix on a specific version tag.
|
||||
|
||||
```go
|
||||
import github.com/blang/semver
|
||||
v1, err := semver.Make("1.0.0-beta")
|
||||
v2, err := semver.Make("2.0.0-beta")
|
||||
v1.Compare(v2)
|
||||
```
|
||||
|
||||
Also check the [GoDocs](http://godoc.org/github.com/blang/semver).
|
||||
|
||||
Why should I use this lib?
|
||||
-----
|
||||
|
||||
- Fully spec compatible
|
||||
- No reflection
|
||||
- No regex
|
||||
- Fully tested (Coverage >99%)
|
||||
- Readable parsing/validation errors
|
||||
- Fast (See [Benchmarks](#benchmarks))
|
||||
- Only Stdlib
|
||||
- Uses values instead of pointers
|
||||
- Many features, see below
|
||||
|
||||
|
||||
Features
|
||||
-----
|
||||
|
||||
- Parsing and validation at all levels
|
||||
- Comparator-like comparisons
|
||||
- Compare Helper Methods
|
||||
- InPlace manipulation
|
||||
- Sortable (implements sort.Interface)
|
||||
- database/sql compatible (sql.Scanner/Valuer)
|
||||
- encoding/json compatible (json.Marshaler/Unmarshaler)
|
||||
|
||||
|
||||
Example
|
||||
-----
|
||||
|
||||
Have a look at full examples in [examples/main.go](examples/main.go)
|
||||
|
||||
```go
|
||||
import github.com/blang/semver

v, err := semver.Make("0.0.1-alpha.preview+123.github")
|
||||
fmt.Printf("Major: %d\n", v.Major)
|
||||
fmt.Printf("Minor: %d\n", v.Minor)
|
||||
fmt.Printf("Patch: %d\n", v.Patch)
|
||||
fmt.Printf("Pre: %s\n", v.Pre)
|
||||
fmt.Printf("Build: %s\n", v.Build)
|
||||
|
||||
// Prerelease versions array
|
||||
if len(v.Pre) > 0 {
|
||||
fmt.Println("Prerelease versions:")
|
||||
for i, pre := range v.Pre {
|
||||
fmt.Printf("%d: %q\n", i, pre)
|
||||
}
|

v001, err := semver.Make("0.0.1")
|
||||
// Compare using helpers: v.GT(v2), v.LT, v.GTE, v.LTE
|
||||
v001.GT(v) == true
|
||||
v.LT(v001) == true
|
||||
v.GTE(v) == true
|
||||
v.LTE(v) == true
|
||||
|
||||
// Or use v.Compare(v2) for comparisons (-1, 0, 1):
|
||||
v001.Compare(v) == 1
|
||||
v.Compare(v001) == -1
|
||||
v.Compare(v) == 0
|
||||
|
||||
// Manipulate Version in place:
|
||||
v.Pre[0], err = semver.NewPRVersion("beta")
|
||||
if err != nil {
|
||||
fmt.Printf("Error parsing pre release version: %q", err)
|
||||
}
|
||||
|
||||
fmt.Println("\nValidate versions:")
|
||||
v.Build[0] = "?"
|
||||
|
||||
err = v.Validate()
|
||||
if err != nil {
|
||||
fmt.Printf("Validation failed: %s\n", err)
|
||||
}
|
||||
```

|
||||
Motivation
|
||||
-----
|
||||
|
||||
I simply couldn't find any lib supporting the full spec. Others were just wrong or used reflection and regex which i don't like.
