regex - Can't figure out the format this file is expecting to read -


i've got block of perl supposed read static file irc hostmask, privilege level , comment. between perl (which i'm certified novice in) , regex i'm having trouble creating file.

sub read_users {     @users = ();      open config, "<", "users";     while (my $line = <config>)     {         next if $line =~ /^\s*#/;         ($mask, $level, $comment) = split /\s+/, $line, 3;          push @users, [$mask, $level];     }     close config; }

the file reads:

<config> irc.hostmask.goes.here 500 comment

that isn't working. see mentions word users , regex omits whitespace. i've grumbled on enough , tried various formulations no luck. ideas?

each line of file must either:

  • a comment (which ignored), consisting of optional whitespace, #, , arbitrary text
  • a "mask", "level", , "comment", separated whitespace, no leading whitespace before mask. mask , level cannot contain whitespace, though comment can.

<config> not valid line; expression my $line = <config> merely reads 1 line config filehandle , stores in $line, , while causes repeat until <config> returns false value (usually undef @ end-of-file).
