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
