Progress Report #9

After some critical debugging of the recently changed runFunctionObject() (used for callbacks), I decided to add a new boolean function in the spirit of doing things fast and efficiently: xall(). This function is the equivalent of any(all(…), nall(…)) where “…” represents the same arguments. Using xall() is much less error prone (since you only need to type the argument names once) and much faster because it’s all on the C++ side.

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).

Bug Fixes (v 6-0.51)

Branch 6, version 0.51 has a couple of important bug fixes.

An old bug in Copper that had gone under the radar for a while: The system functions “all” and “any” had been flipped in functionality. Each one was doing the other’s job. The bug was probably introduced during a rewrite of those functions.

CallbackWrapper was also fixed. The Copper callback is now disowned in the destructor so its lifetime is now correctly tied to the CallbackWrapper.
