NAME

Perl::Critic::Policy::Compatibility::ProhibitThreeArgumentOpen - Don't allow three-argument open unless the code uses a version of perl that supports it.

AFFILIATION

This policy is part of Perl::Critic::Compatibility.

VERSION

This document describes Perl::Critic::Policy::Compatibility::ProhibitThreeArgumentOpen version 1.001.

SYNOPSIS

Don't allow three-argument open unless the module declares a dependency upon perl 5.6 or higher.

DESCRIPTION

Perls prior to 5.6 don't support the three-argument form of open. If you want your code to remain compatible with those versions of perl, you can't use it.

If your code explicitly declares a requirement on a version of perl greater than or equal to 5.6, then three-argument open is fine.

open FILE, '<', 'blah';             # not ok

use 5.006;
open FILE, '<', 'blah';             # ok

require 5.8.8;
open FILE, '<', 'blah';             # ok

INTERFACE

Standard for a Perl::Critic::Policy.

DIAGNOSTICS

None.

CONFIGURATION AND ENVIRONMENT

This policy has no configuration options beyond the standard ones.

DEPENDENCIES

Perl::Critic

INCOMPATIBILITIES

This policy directly contradicts Perl::Critic::Policy::InputOutput::ProhibitTwoArgOpen. If you don't declare perl version requirements, then you cannot have both of these policies enabled at the same time (unless you like getting violations).

BUGS AND LIMITATIONS

No bugs have been reported.

Please report any bugs or feature requests to bug-perl-critic-compatible@rt.cpan.org, or through the web interface at http://rt.cpan.org.
