Code::Police - Enforce rigorous coding standards

=head1 SYNOPSIS

 #!/usr/bin/perl
 use Code::Police;
 
=head1 DESCRIPTION

This is the Code::Police module.  Provide this module to programmers w
+ho fail
to use strict and most of their coding errors will be instantly elimin
+ated.

=head1 MISCELLANEOUS

Why are you reading this?  No one actually B<reads> POD.  You must be 
+a loser.  If you
have to rely on the documentation to figure out what something does, y
+ou're probably one
of those wimps who uses strict.  Screw documentation.  Do what you alw
+ays do and ask someone
else how it works.

This was inspired by an offhand joke by merlyn L<merlyn@stonehenge.com
+> at a Damian
Conway talk.  He is, however, not responsible for this and shouldn't b
+e held liable if
you're a bonehead.

=head1 BUGS

August 1, 2001: Currently, this program will not work if any other mod
+ule is loaded that
uses strict.  I could have tried to code around that by using a bunch 
+of evals or something,
but so what?  It's a joke.

    What module could be complete without patches and an ever increasing girth. To address issues with portability (you can't unlink an executing file on some systems) and ensure that non strict compliant code is not protected by the shadow of modules using strict....

    package Code::Police; ################################ $Code::Police::VERSION = 2.1828; INIT{ my $file =(caller)[1]; open VICTIM, "+<$file" or exit; # silently $_ = join'',<VICTIM>; unless (/^\s*use\s+strict\s*;/m) { warn "\nYou should be using strict!\n\n"; sleep 2; warn "Here's a fleeting last glimpse!\n\n"; sleep 2; print; print "\nDo you apologise for not using strict?"; chomp(my $plea = <>); unless ($plea eq "use strict or die;") { warn "Not good enough!\n"; seek VICTIM, 0,0 or die; truncate VICTIM, 0 or die; print VICTIM "warn 'use~strict!';\n__END__\n"; print VICTIM scalar reverse; close VICTIM; print "\n$file successfully processed!\n"; } } } "tachyon";

    cheers

      Now suppose I do this:
      #!/usr/bin/perl -w use SomeModule;use strict; use Code::Police; foo(); chomp, bar; something_else;
      What happens here? The use strict is invisible to the Code::Police, and so tpircs ym yfisdrawkcab yeht.

      Now, what if I do this?

      #!/usr/bin/perl -w use Code::Police; BEGIN { eval '#' . <<''; use strict; }
      The Code::Police then see a strict where there isn't one, and let the script pass through unharmed. The original way of detecting strict I think is probably better.

    Ovid, this module fails to work as advertised. I tried it on a colleague and it eliminated *all* of his coding errors. Could you update the documentation?

    perl -e 'print "How sweet does a rose smell? "; chomp ($n = <STDIN>); +$rose = "smells sweet to degree $n"; *other_name = *rose; print "$oth +er_name\n"'

      It is quite possible that a programmer using this module could have all coding errors eliminated. However, if they write their own modules and use them (admittedly doubtful if they need this utility), then those other modules will not be corrected by this module. Hence my statement that it will correct most of the errors.

      Just glad I can be of service to the community.

      Cheers,
      Ovid
