semver for golang [![Build Status](https://travis-ci.org/blang/semver.svg?branch=master)](https://travis-ci.org/blang/semver) [![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
- Ranges `>=1.0.0 <2.0.0 || >=3.0.0 !3.0.1-beta.1`
- Wildcards `>=1.x`, `<=2.5.x`
- Sortable (implements sort.Interface)
- database/sql compatible (sql.Scanner/Valuer)
- encoding/json compatible (json.Marshaler/Unmarshaler)
Ranges
------
A `Range` is a set of conditions which specify which versions satisfy the range.
A condition is composed of an operator and a version. The supported operators are:
- `<1.0.0` Less than `1.0.0`
- `<=1.0.0` Less than or equal to `1.0.0`
- `>1.0.0` Greater than `1.0.0`
- `>=1.0.0` Greater than or equal to `1.0.0`
- `1.0.0`, `=1.0.0`, `==1.0.0` Equal to `1.0.0`
- `!1.0.0`, `!=1.0.0` Not equal to `1.0.0`. Excludes version `1.0.0`.
Note that spaces between the operator and the version will be gracefully tolerated.
A `Range` can link 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`
Range usage:
```
v, err := semver.Parse("1.2.3")
range, err := semver.ParseRange(">1.0.0 <2.0.0 || >=3.0.0")
if range(v) {
//valid
}
```
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)
}
}
// Build meta data array
if len(v.Build) > 0 {
fmt.Println("Build meta data:")
for i, build := range v.Build {
fmt.Printf("%d: %q\n", i, build)
}
}
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.
Contribution
-----
Feel free to make a pull request. For bigger changes create a issue first to discuss about it.
