One of the features I had been meaning to get around to for some time was improvements to the logging. The original system had one enum value per error. It gets quite tedious pretty quickly when you have to write out redundant messages with only a single word changed. Since it would be nice to have the messages be localized (i.e. translated into different languages), I used an enum, but obviously, I needed to shorten the process.
The result of my long evening of work was a rewrite of part of the logging system that resulting in an easily extensible interface for which I created pretty print logging (which you can see in the feature image of this post).
