Semantic Versioning implementation in Kotlin. Semver represents the versioning system specified in Semantic Versioning Specification.

Semver requires no external dependencies. You can install the library via:

// build.gradle
repositories {
    jcenter()
}
dependencies {
    implementation 'com.github.glwithu06.semver:semver:x.y.z'
}

// build.gradle
repositories {
    maven { url 'https://jitpack.io' }
}
dependencies {
    implementation 'com.github.glwithu06:semver.kt:x.y.z'
}

You can create a Semver instance like the following:

val version = Semver(major = 1, minor = 23, patch = 45, prereleaseIdentifiers = listOf("rc", "1"), buildMetadataIdentifiers = listOf("B001"))

minor, patch are optional parameters and set to "0" by default.

prereleaseIdentifiers, buildMetadataIdentifiers are optional parameters and set to empty lists by default.

You can create Semver from String:

val version = Semver("1.23.45-rc.1+B001")

or from Numeric:

val version = Semver(1.23)

val version = Semver(10)

If the given argument has an invalid format, it throws a IllegalArgumentException.

Semver class implements Comparable interface and overrides equals(), so their instances can be compared using the default operators including < , <= , > ,>= ,== , !=.

The comparison rules are specified in Semantic Versioning Specification.
