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
|
||||
}
|
||||
|
||||
```
|
||||
|
||||

|

|
||||
fmt.Println("Prerelease versions:")
|
||||
for i, pre := range v.Pre {
|
||||
fmt.Printf("%d: %q\n", i, pre)
|

}

}

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.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.

But wait, since gzip decompression is inherently singlethreaded (aside from CRC calculation) how can it be more than 100% faster? Because pgzip due to its design also acts as a buffer. When using unbuffered gzip, you are also waiting for io when you are decompressing. If the gzip decoder can keep up, it will always have data ready for your reader, and you will not be waiting for input to the gzip decompressor to complete.
