Re: A perverse use of grep

I don't so much object to the destructive grep as to the fact that it's using a substitution for what should be a negated pattern match:

my @lines = grep { s/^\s+//; s/\s+$//; length > 0 && !/^#/ } <$in>;

But this is all aesthetics anyway,

Your code fails to strip comments off lines it will keep, though. :) `keep this part # part strip this part` [download] Update: That wasn't an intended feature. I guess I'm just too used to doing that since it's so easy to handle. :) -- brian d foy <brian@stonehenge.com>	[reply] [d/l]

True, but the "spec" for the OP didn't say that. It just said to ignore lines starting with # :)	[reply]

Yes, Errto is right, the super simple config file format specified for this project only supports comment lines where the first non-white space char is `#`.	[reply] [d/l]
