NAME
Perl::Critic::Policy::ControlStructures::ProhibitUnreachableCode - Don't write code after an unconditional "die, exit, or next". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
This policy prohibits code following a statement which unconditionally alters the program flow. This includes calls to "exit", "die", "return", "next", "last" and "goto". Due to common usage, "croak" and "confess" from Carp are also included. Code is reachable if any of the following conditions are true: o Flow-altering statement has a conditional attached to it o Statement is on the right side of an operator "&&", "||", "//", "and", "or", or "err". o Code is prefixed with a label (can potentially be reached via "goto") o Code is a subroutine EXAMPLES
# not ok exit; print "123 "; # ok exit if !$xyz; print "123 "; # not ok for ( 1 .. 10 ) { next; print 1; } # ok for ( 1 .. 10 ) { next if $_ == 5; print 1; } # not ok sub foo { my $bar = shift; return; print 1; } # ok sub foo { my $bar = shift; return if $bar->baz(); print 1; } # not ok die; print "123 "; # ok die; LABEL: print "123 "; # not ok croak; do_something(); # ok croak; sub do_something {} CONFIGURATION
This Policy is not configurable except for the standard options. SEE ALSO
