NAME
Perl::Critic::Policy::Freenode::BarewordFilehandles - Don't use bareword filehandles other than built-ins
DESCRIPTION
Bareword filehandles are allowed in open() as a legacy feature, but will use a global package variable. Instead, use a lexical variable with my so that the filehandle is scoped to the current block, and will be automatically closed when it goes out of scope. Built-in bareword filehandles like STDOUT and DATA are ok.
open FH, '<', $filename; # not ok
open my $fh, '<', $filename; # okThis policy is similar to the core policy Perl::Critic::Policy::InputOutput::ProhibitBarewordFileHandles, but allows more combinations of built-in bareword handles and filehandle-opening functions such as pipe and socketpair.
AFFILIATION
This policy is part of Perl::Critic::Freenode.
CONFIGURATION
This policy is not configurable except for the standard options.
