Bayesian Tail

flok writes "We all know anti-spam-software using Bayesian filtering. The results with these are amazingly good. So that made me thinking: why not create a tool which monitors logfiles and determines using a Bayesian filter what events to display and what not? That's why I created btail. Btail is just that: it monitors a logfile and filters it with a Bayesian filter. The results are above my own expectations!"

the Daily WTF!

To Wit:

char *conf_file = "btail.conf";

if (argc > 2)
{
fprintf(stderr, "Usage: %s [configurationfile]\n", argv[0]);
return 1;
}
else if (argc == 2)
{
conf_file = argv[1];
}
conf *config = load_config(conf_file);

C'mon, man... really, WTF? How would the user know from the "error" message that the program will use a default config file (and with what name)?

That aside, your code would be easier to read (slashcode's broken formatting nonwithstanding) if you used a switch construct.

// If the user doesn't want to specify a config, we'll use the default
switch( argc ) {
case 1:
confg_file = "btail.conf";
break;
case 2:
conf_file = argv[1];
break;
default:
fprintf(stderr, "Usage: %s [configurationfile (defaults to btail.conf)]\n", argv[0]);
return 1;
}
