README

Provides many different popular version comparison algorithms as string comparisons. See the docs for more information.

Another version comparison library, you ask? Well, yes.

Why? Because there are lots of version comparison schemes out there, far more than just SemVer. This library supports several:

• Debian package version comparison
• Maven (org.apache.maven.artifact.versioning.ComparableVersion) version comparison
• Naive (old RPM) version comparison
• Python (PEP 440) version comparison
• RPM version comparison
• Ruby (Gem::Version) version comparison
• SemVer 2.0 version comparison

It supports so many by normalizing the version number according what scheme is being used, then feeds the newly transformed version numbers to the venerable debian version comparison algorithm for comparison.

Jan?

Johannes Vermeer (JanVer) is the inspiration for this library's name.

Usage

To import:

import (
	"gitlab.com/djhaskin987/janver/pkg/vercmp"
)

To use:

vercmp.MavenCompare(avers, bvers)

You'll get a negative, positive, or zero value depending on whether avers < bvers, avers > bvers, or avers = bvers, respectively. :)

If this does not work as advertised, please log a bug :)
