|
|
==============================
|
|
|
|
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"}
