+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
+- Ranges `>=1.0.0 <2.0.0 || >=3.0.0 !3.0.1-beta.1`
+- 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`.
+
+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.

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+There are far too many logging packages out there, with varying degrees of licenses, far too many features (colorization, all sorts of log frameworks) or are just a pain to use (lack of `Fatalln()`?).
+capnslog provides a simple but consistent logging interface suitable for all kinds of projects.
+
+### Design Principles
+
+##### `package main` is the place where logging gets turned on and routed
+
+A library should not touch log options, only generate log entries. Libraries are silent until main lets them speak.
+
+##### All log options are runtime-configurable. 
+
+Still the job of `main` to expose these configurations. `main` may delegate this to, say, a configuration webhook, but does so explicitly. 
+
+##### There is one log object per package. It is registered under its repository and package name.
+
+`main` activates logging for its repository and any dependency repositories it would also like to have output in its logstream. `main` also dictates at which level each subpackage logs.
+
+##### There is *one* output stream, and it is an `io.Writer` composed with a formatter.
+
+Splitting streams is probably not the job of your program, but rather, your log aggregation framework. If you must split output streams, again, `main` configures this and you can write a very simple two-output struct that satisfies io.Writer.
+
+Fancy colorful formatting and JSON output are beyond the scope of a basic logging framework -- they're application/log-collector dependent. These are, at best, provided as options, but more likely, provided by your application.
+
+##### Log objects are an interface
+
+An object knows best how to print itself. Log objects can collect more interesting metadata if they wish, however, because text isn't going away anytime soon, they must all be marshalable to text. The simplest log object is a string, which returns itself. If you wish to do more fancy tricks for printing your log objects, see also JSON output -- introspect and write a formatter which can handle your advanced log interface. Making strings is the only thing guaranteed.
+
+##### Log levels have specific meanings:
+
+  * Critical: Unrecoverable. Must fail.
+  * Error: Data has been lost, a request has failed for a bad reason, or a required resource has been lost
+  * Warning: (Hopefully) Temporary conditions that may cause errors, but may work fine. A replica disappearing (that may reconnect) is a warning.
+  * Notice: Normal, but important (uncommon) log information.
+  * Info: Normal, working log information, everything is fine, but helpful notices for auditing or common operations.
+  * Debug: Everything is still fine, but even common operations may be logged, and less helpful but more quantity of notices.
+  * Trace: Anything goes, from logging every function call as part of a common operation, to tracing execution of a query.

+//   the content-type used (for further details, consult http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4).
+//   * `application/x-www-form-urlencoded` - Similar to the format of Query parameters but as a payload.
+//   For example, `foo=1&bar=swagger` - both `foo` and `bar` are form parameters. This is normally used for simple
+//   parameters that are being transferred.
+//   * `multipart/form-data` - each parameter takes a section in the payload with an internal header.
+//   For example, for the header `Content-Disposition: form-data; name="submit-name"` the name of the parameter is
+//   `submit-name`. This type of form parameters is more commonly used for file transfers.
