Perl::Critic::Policy::InputOutput::RequireCheckedOpen(3)User Contributed Perl DocumentatioPerl::Critic::Policy::InputOutput::RequireCheckedOpen(3) 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. AUTHOR
