perl::critic::policy::inputoutput::requirecheckedopen

Perl::Critic::Policy::InputOutput::RequireCheckedOpen(3pUser Contributed Perl DocumentatPerl::Critic::Policy::InputOutput::RequireCheckedOpen(3pm)

NAME

       Perl::Critic::Policy::InputOutput::RequireCheckedOpen - Write "my $error = open $fh, $mode, $filename;" instead of "open $fh, $mode,
       $filename;".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       The perl builtin I/O function "open" returns a false value on failure. That value should always be checked to ensure that the open was
       successful.

	   my $error = open( $filehandle, $mode, $filename );		       # ok
	   open( $filehandle, $mode, $filename ) or die "unable to open: $!";  # ok
	   open( $filehandle, $mode, $filename );			       # not ok

	   use autodie;
	   open $filehandle, $mode, $filename;				       # ok

       You can use autodie, Fatal, or Fatal::Exception to get around this.  Currently, autodie is not properly treated as a pragma; its lexical
       effects aren't taken into account.

CONFIGURATION

       This Policy is not configurable except for the standard options.
