NAME

       Perl::Critic::Policy::ControlStructures::ProhibitCascadingIfElse - Don't write long
       "if-elsif-elsif-elsif-elsif...else" chains.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Long "if-elsif" chains are hard to digest, especially if they are longer than a single
       page or screen.  If testing for equality, use a hash lookup instead.  If you're using perl
       5.10 or later, use "given"/"when".

           if ($condition1) {         #ok
               $foo = 1;
           }
           elsif ($condition2) {      #ok
               $foo = 2;
           }
           elsif ($condition3) {      #ok
               $foo = 3;
           }
           elsif ($condition4) {      #too many!
               $foo = 4;
           }
           else {                     #ok
               $foo = $default;
           }

CONFIGURATION

       This policy can be configured with a maximum number of "elsif" alternatives to allow.  The
       default is 2.  This can be specified via a "max_elsif" item in the .perlcriticrc file:

           [ControlStructures::ProhibitCascadingIfElse]
           max_elsif = 3
