- The command handler has been drastically simplified. We were doing way too much processing in the handler that should have been done in the individual command functions themselves. - The 'cdat' dict we were previously passing around has been replaced with a Command object that has useful methods for performing some of the parsing command functions will probably want to do from time to time. - All commands were updated to use the new Command object, tested, and cleaned up in general. - A lot of formatting was cleaned up. - A lot of previously un-found bugs and limitations were fixed. - The 'page' command has been broken out into its own file, since it's going to have a number of functions that would otherwise clutter commands/general.py. Expect a commit (probably later today) that will clean up the second half of cmdhandler.py.
