I found a code analysis and metrics program called SourceMonitor today. I downloaded version 188.8.131.52 and fed it the source files for Basternae. Here’s what it came up with:
% Branches: 29.2
% Comments: 8.6
Class Definitions: 43
Average Statements/Method: 14.2
Max Complexity: 477
Max Depth: 8
Average Depth: 1.87
Average Complexity: 12.41
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.
