# Versioning Library for Go
|
||||
[![Build Status](https://circleci.com/gh/hashicorp/go-version/tree/master.svg?style=svg)](https://circleci.com/gh/hashicorp/go-version/tree/master)
|
||||
[![GoDoc](https://godoc.org/github.com/hashicorp/go-version?status.svg)](https://godoc.org/github.com/hashicorp/go-version)
|
||||
|
||||
go-version is a library for parsing versions and version constraints,
|
||||
and verifying versions against a set of constraints. go-version
|
||||
can sort a collection of versions properly, handles prerelease/beta
|
||||
versions, can increment versions, etc.
|
||||
|
||||
Versions used with go-version must follow [SemVer](http://semver.org/).
|
||||
|
||||
## Installation and Usage
|
||||
|
||||
Package documentation can be found on
|
||||
[GoDoc](http://godoc.org/github.com/hashicorp/go-version).
|
||||
|
||||
Installation can be done with a normal `go get`:
|
||||
|
||||
```
|
||||
$ go get github.com/hashicorp/go-version
|
||||
```
|
||||
|
||||
#### Version Parsing and Comparison
|
||||
|
||||
```go
|
||||
v1, err := version.NewVersion("1.2")
|
||||
v2, err := version.NewVersion("1.5+metadata")
|
||||
|
||||
// Comparison example. There is also GreaterThan, Equal, and just
|
||||
// a simple Compare that returns an int allowing easy >=, <=, etc.
|
||||
if v1.LessThan(v2) {
|
||||
fmt.Printf("%s is less than %s", v1, v2)
|
||||
}
|
||||
```
|
||||
|
||||
#### Version Constraints
|
||||
|
||||
```go
|
||||
v1, err := version.NewVersion("1.2")
|
||||
|
||||
// Constraints example.
|
||||
constraints, err := version.NewConstraint(">= 1.0, < 1.4")
|
||||
if constraints.Check(v1) {
|
||||
fmt.Printf("%s satisfies constraints %s", v1, constraints)
|
||||
}
|
||||
```
|
||||
|
||||
#### Version Sorting
|
||||
|
||||
```go
|
||||
versionsRaw := []string{"1.1", "0.7.1", "1.4-beta", "1.4", "2"}
|
||||
versions := make([]*version.Version, len(versionsRaw))
|
||||
for i, raw := range versionsRaw {
|
||||
v, _ := version.NewVersion(raw)
|
||||
versions[i] = v
|
||||
}
|
||||
|
||||
// After this, the versions are properly sorted
|
||||
sort.Sort(version.Collection(versions))
|
||||
```
|
||||
|
||||

==============================
|
||||
|
||||
Version normalizer and comparison library for go, heavy based on PHP version_compare function and Version comparsion libs from [Composer](https://github.com/composer/composer) PHP project
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
The recommended way to install go-version
|
||||
|
||||
```
|
||||
go get github.com/mcuadros/go-version
|
||||
```
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
How import the package
|
||||
|
||||
```go
|
||||
import (
|
||||
"github.com/mcuadros/go-version"
|
||||
)
|
||||
```
|
||||
|
||||
`version.Normalize()`: Normalizes a version string to be able to perform comparisons on it
|
||||
|
||||
```go
|
||||
version.Normalize("10.4.13-b")
|
||||
//Returns: 10.4.13.0-beta
|
||||
```
|
||||
|
||||
|
||||
`version.CompareSimple()`: Compares two normalizated version number strings
|
||||
|
||||
```go
|
||||
version.CompareSimple("1.2", "1.0.1")
|
||||
//Returns: 1
|
||||
|
||||
version.CompareSimple("1.0rc1", "1.0")
|
||||
//Returns: -1
|
||||
```
|
||||
|
||||
|
||||
`version.Compare()`: Compares two normalizated version number strings, for a particular relationship
|
||||
|
||||
```go
|
||||
version.Compare("1.0-dev", "1.0", "<")
|
||||
//Returns: true
|
||||
|
||||
version.Compare("1.0rc1", "1.0", ">=")
|
||||
//Returns: false
|
||||
|
||||
version.Compare("2.3.4", "v3.1.2", "<")
|
||||
//Returns: true
|
||||
```
|
||||
|
||||
`version.ConstrainGroup.Match()`: Match a given version againts a group of constrains, read about constraint string format at [Composer documentation](http://getcomposer.org/doc/01-basic-usage.md#package-versions)
|
||||
|
||||
```go
|
||||
c := version.NewConstrainGroupFromString(">2.0,<=3.0")
|
||||
c.Match("2.5.0beta")
|
||||
//Returns: true
|
||||
|
||||
c := version.NewConstrainGroupFromString("~1.2.3")
|
||||
c.Match("1.2.3.5")
|
||||
//Returns: true
|
||||
```
|
||||
|
||||
`version.Sort()`: Sorts a string slice of version number strings using version.CompareSimple()
|
||||
|
||||
```go
|
||||
version.Sort([]string{"1.10-dev", "1.0rc1", "1.0", "1.0-dev"})
|
||||
//Returns []string{"1.0-dev", "1.0rc1", "1.0", "1.10-dev"}
|
||||

//
|
||||
// Exact version: You can specify the exact version of a package, for
|
||||
// example 1.0.2.
|
||||
//
|
||||
// Range: By using comparison operators you can specify ranges of valid versions.
|
||||
// Valid operators are >, >=, <, <=, !=. An example range would be >=1.0. You can
|
||||
// define multiple ranges, separated by a comma: >=1.0,<2.0.
|
||||
//
|
||||
// Wildcard: You can specify a pattern with a * wildcard. 1.0.* is the equivalent
|
||||
// of >=1.0,<1.1.
|
||||
//
|
||||
// Next Significant Release (Tilde Operator): The ~ operator is best explained by
|
||||
// example: ~1.2 is equivalent to >=1.2,<2.0, while ~1.2.3 is equivalent to
|
||||
// >=1.2.3,<1.3. As you can see it is mostly useful for projects respecting
|
||||
// semantic versioning. A common usage would be to mark the minimum minor
|
||||
// version you depend on, like ~1.2 (which allows anything up to, but not
|
||||
// including, 2.0). Since in theory there should be no backwards compatibility
|
||||
// breaks until 2.0, that works well. Another way of looking at it is that
|
||||
// using ~ specifies a minimum version, but allows the last digit specified
|
||||
// to go up.
|
||||
//
|
||||
// By default only stable releases are taken into consideration. If you would like
|
||||
// to also get RC, beta, alpha or dev versions of your dependencies you can do so
|
||||
// using stability flags. To change that for all packages instead of doing per
|
||||
// dependency you can also use the minimum-stability setting.
