Build Status


Semantic Version library for Haxe. The library provides an abstract type thx.semver.Version that represents a release version as described in the Semantic Versioning Specification 2.0.0.

To create a version you can use a string:

var v : Version = '1.2.3';

Or an array:

var v : Version= [1,2,3];

In this case you will not be able to specify a pre-release (pre) or a build value. But you can integrate using one of the transformation methods:

var v = ([1,2,3] : Version).withBuild('abc');

Versions can be easily compared:

('1.0.0' : Version) > ('1.0.0-alpha' : Version) // yields true

A version with pre-release and build looks like:

var v : Version = '1.0.0-alpha+build.12'

Also generating new versions is very easy:

var v : Version = '0.9.17';
trace(v.nextMinor()); // echoes '0.10.0'

Version Rules

thx.semver support the same SemVer patterns adopted for npm-semver. Note that this is neither a wrapper or a port but a library that conforms to the same specifications.

The simplest way to define a Version Rule is to use the string format:

var rule : VersionRule = '1.x || >=2.5.0 || 5.0.0 - 7.2.3';
rule.isSatisfiedBy('1.2.3'); // holds true

You can also operate in the other direction:

('1.2.3' : Version).satisfies('1.x || >=2.5.0 || 5.0.0 - 7.2.3'); // holds true

For more details on the patterns, refer to the previous link.


From the command line just type:

haxelib install thx.semver

To use the dev version do:

haxelib git thx.core
