+semver for golang [](https://travis-ci.org/blang/semver) [](https://godoc.org/github.com/blang/semver) [](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.
