Perl::Critic::Policy::Community::ConditionalDeclarations - 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
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 community theme.
This policy is part of Perl::Critic::Community.
This policy is not configurable except for the standard options.
