SemVer

Kotlin data class for Semantic Versioning 2.0.0 specification.

repositories {
    mavenCentral()
}

dependencies {
    implementation 'net.swiftzer.semver:semver:1.1.2'
}

Usage

Parsing version number

val version: SemVer = SemVer.parse("1.0.0-beta+exp.sha.5114f85")

version.major // 1
version.minor // 0
version.patch // 0
version.preRelease // "beta"
version.buildMetadata // "exp.sha.5114f85"

Comparing version numbers

val semVer1 = SemVer(1, 0, 0)
val semVer2 = SemVer(1, 0, 2)
assertEquals(-1, semVer1.compareTo(semVer2))

Creating next version numbers

val semVer = SemVer(1, 3, 5)
assertEquals(SemVer(1, 3, 6), semVer.nextPatch())
assertEquals(SemVer(1, 4, 0), semVer.nextMinor())
assertEquals(SemVer(2, 0, 0), semVer.nextMajor())
