semver

go-semver

A lightweight and idiomatic Go package to parse and compare semantic versions based on the Semantic Versioning 2.0.0 specification.

✨ Features

• Parse semantic version strings (MAJOR.MINOR.PATCH[-PRERELEASE][+BUILD])
• Compare versions with full support for precedence rules
• Handle pre-release and build metadata
• Determine ordering between two versions
• Idiomatic Go API

📦 Installation

go get github.com/Nidal-Bakir/go-semver

🛠️ Usage

package main

import (
    "fmt"
    "github.com/Nidal-Bakir/go-semver"
)

func main() {
    v1, _ := semver.Parse("1.2.3-alpha.1")
    v2, _ := semver.Parse("1.2.3")

    if v1.IsLess(v2) {
        fmt.Println(v1, "is less than", v2)
    }
}

🔍 Version Comparison Rules

This package follows the precedence rules defined in the Semantic Versioning 2.0.0 spec, including:

• Precedence is determined by the major, minor, and patch versions, in that order.

• Pre-release versions have lower precedence than the associated normal version.

• Build metadata does not affect version precedence.
