Comparing versions with wildcards and without them (for instance for semantic versioning)

Posted by jpluimers on 2020/08/12

For a project I’m going to be in need to compare version numbers.

I’m not sure yet if I need wildcards, or can leave them out (but for partial semantic versioning, I might need them).

Below a bunch of links that should get me started.

From a quick glance: versioning is hard, comparing even harder.

On versioning in general

Numeric versioning (usually without wildcards):

On semantic versioning (SemVer for short):

On the C# Version class (which handles most of semantic versioning except: leading zero’s, very large numbers, non-numeric release specifiers)

Interesting idea, but not sustainable: using floating point values to compare versions:

On wildcards:

Via: [WayBack] Anyone tips for a TVersion structure that supports at max quad digits or wildcards and comparison? Like 3.2 matching 3.2.5.7, but not matching 3.3.4.28 ? – Jeroen Wiert Pluimers – Google+
