Ahh, the joy of code metrics.

For the first time, the number of lines of code has gone down.  This is because MobProgs were removed.  We also lost about another 400 or so lines because the change to saving objects using XML allowed us to eliminate some duplicate code (repeat after me kids: Duplicate code is BAAAD!)   The average complexity also seems to be gradually decreasing a little.  In general that’s a good thing, since maintainability of code is generally thought to be the inverse of its complexity.

I just love these statistics tools…

The number of files, class definitions, and methods per class has increased, while the statements per method and average complexity has decreased.

I found a code analysis and metrics program called SourceMonitor today. I downloaded version 2.3.6.1 and fed it the source files for Basternae. Here’s what it came up with:

The check_command() function in the command interpreter is the most complex function. The complexity rating of 477 comes from the fact that it has 477 different branches of execution – essentially 1 for each different command the MUD understands.

Since this code is hybrid C and C++, the average number of statements per method metric doesn’t giev a full picture of things. It’s still pretty interesting to see the statistics on things.

SourceMonitor keeps track of “checkpoints” and lets you look at how code evolves over time, so it’ll be interesting to fire it up and post statistics now and then.
