perl::critic::command

Perl::Critic::Command(3)				User Contributed Perl Documentation				  Perl::Critic::Command(3)

NAME

       Perl::Critic::Command - Guts of perlcritic.

SYNOPSIS

	   use Perl::Critic::Command qw< run >;

	   local @ARGV = qw< --statistics-only lib bin >;
	   run();

DESCRIPTION

       This is the implementation of the perlcritic command.  You can use this to run the command without going through a command interpreter.

INTERFACE SUPPORT

       This is considered to be a public class.  However, its interface is experimental, and will likely change.

IMPORTABLE SUBROUTINES

       "run()"
	   Does the equivalent of the perlcritic command.  Unfortunately, at present, this doesn't take any parameters but uses @ARGV to get its
	   input instead.  Count on this changing; don't count on the current interface.

TO DO

       Make "run()" take parameters.  The equivalent of @ARGV should be passed as a reference.

       Turn this into an object.
