clj-semver

Functions for parsing, comparison, and manipulation of semantic version strings. The intent is to implement the actual spec, including proper comparisons on pre-release and build fields.

Installation

clj-semver is available as a Maven artifact via Clojars.

Use the following build dependency:

[grimradical/clj-semver "0.3.0-SNAPSHOT"]

A non-snapshot release is forthcoming!

Usage

The main namespace for date-time operations in the clj-semver library is clj-semver.core.

user> (use 'clj-semver.core)

Parse a version string:

user> (version "1.0.0")
{:major 1, :minor 0, :patch 0, :pre-release nil, :build nil}

user> (version "1.0.0-alpha.1")
{:major 1, :minor 0, :patch 0, :pre-release "alpha.1", :build nil}

user> (version "1.0.0-alpha.1+build.234")
{:major 1, :minor 0, :patch 0, :pre-release "alpha.1", :build "build.234"}

They are regular clojure maps, so you can interrogate them the expected way:

user> (:minor (version "1.2.3"))

The version function is idempotent, so you can call it on a pre-parsed version and it'll will just pass-through the value. This makes it easier to create functions that operate on either string versions, or parsed version maps.

Comparison is straightforward:

user> (newer? "1.2.0" "1.0.1")
true
user> (older? "1.0.0-alpha.1" "1.0.0")
true

...etc
