Perl::Critic::Policy::Freenode::ProhibitConditionalDeclarations - Don't declare variables conditionally
It is possible to add a postfix condition to a variable declaration, like "my $foo = $bar if $baz". However, it is unclear (and undefined) if the variable will be declared when the condition is not met. Instead, declare the variable and then assign to it conditionally, or use the ternary operator to assign a value conditionally. my $foo = $bar if $baz; # not ok my ($foo, $bar) = @_ unless $baz; # not ok our $bar = $_ for 0..10; # not ok my $foo; $foo = $bar if $baz; # ok my $foo = $baz ? $bar : undef; # ok This policy is a subclass of the core policy Perl::Critic::Policy::Variables::ProhibitConditionalDeclarations, and performs the same function but in the "freenode" theme.
This policy is part of Perl::Critic::Freenode.
This policy is not configurable except for the standard options.
