Bump is a library for working with semantic versioning following the Semantic Versioning 2.0.0 specification. It supports validation, precedence comparison, and increasing version numbers.

A SemVer object representing the version can be created by supplying arguments for the version, preRelease and buildMetaData parts to the constructor or by supplying a string which will be parsed by the SemVerParser using parser combinators.

Bump is published for Scala 2.13. To start using it add the following to your build.sbt:

libraryDependencies += "nl.gn0s1s" %% "bump" % "0.1.3"

import nl.gn0s1s.bump._

val version = SemVer(1, 0, 1, Some("alpha"), Some("20180329")) // version: nl.gn0s1s.bump.SemVer = 1.0.1-alpha+20180329

version.nextMinor.withoutPreRelease.withoutBuildMetadata // res0: nl.gn0s1s.bump.SemVer = 1.1.0

val version2 = SemVer("2.0.0").get // version2: nl.gn0s1s.bump.SemVer = 2.0.0

version < version2 // res1: Boolean = true

version2.nextPatch // res2: nl.gn0s1s.bump.SemVer = 2.0.1

val invalidVersion = SemVer("3.0") // invalidVersion: Option[nl.gn0s1s.bump.SemVer] = None

The following methods are available on a SemVer object:

• toString - returns the semantic versioning 2.0.0 string
• compare - compares the precedence to the supplied SemVer
• nextMajor/bumpMajor - returns a new SemVer with an incremented major and reset (0) minor and patch version numbers
• nextMinor/bumpMinor - returns a new SemVer with an incremented minor and a reset (0) patch version number
• nextPatch/bumpPatch - returns a new SemVer with an incremented patch version number
• nextStable - returns a new SemVer without pre-release information or an incremented patch version number
• withMajor - returns a new SemVer with the supplied major version number
• withMinor - returns a new SemVer with the supplied minor version number
• withPatch - returns a new SemVer with the supplied patch version number
• withPreRelease - returns a new SemVer with the supplied preRelease string
• withoutPreRelease - returns a new SemVer without pre-release information
• withBuildMetadata - returns a new SemVer with the supplied buildMetadata string
• withoutBuildMetadata - returns a new SemVer without build metadata
