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 ($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
