Re: empty 'else' block

in reply to empty 'else' block

Actually, I have stuff like this littered throughout my code. When I'm developing, I need something to happen to tell me the if statement didn't execute. If the statement is something like this:
if ($foo) { print LOG "Exit condition $foo reached.\n"; exit 0; }
...then no big deal. If the code is more like this:
if ($line =~ /\w+sql=\w+/i) { $db = "mysql"; $db_loc = (split(/=/, $line))[1]; }
...then during the testing period I need to account for a failure condition.
else { print DEBUG "Error: Couldn't parse a database out of line ($line)\n +"; }
In the field, I'd probably delete the error message, but there's a good chance that I'd leave the else statement in so I could re-enable it later if neccessary.
