AFFILIATIONThis Policy is part of the core Perl::Critic distribution.
DESCRIPTIONThe 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.
CONFIGURATIONThis Policy is not configurable except for the standard options.
