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:

Inspecting/unpacking a Linux rpm file on Mac OS X

Posted by jpluimers on 2016/11/18

You need this statement to unpack an rpm file on Mac OS X without having rpm installed:

rpm2cpio ##filename.rpm## | cpio -idmv

This will make rpm2cpio unpack the rpm file in the current directory using these cpio options:

  • i – use the rpm2cpoio as unput
  • d – created directories when needed
  • m – set modification timestamps from the archive
  • v – verbose filenames to stderr

cpio is already part of the Mac OS X system.

You can get rpm2cpio through homebrew by typing brew install rpm2cpio which will likely also download he xz dependency.
