Perl::Critic::Policy::Community::PreferredAlternatives(3pm)

Overview

Various modules have alternatives that are preferred by some subsets of the community, for various reasons which may include: buggy behavior, cruft, performance problems, maintainer issues, or simply better modern replacements. This is a low severity complement to Perl::Critic::Policy::Community::DiscouragedModules.

Modules

Getopt::Std

Getopt::Std was the original very simplistic command-line option processing module. It is now obsoleted by the much more complete solution Getopt::Long, which also supports short options, and is wrapped by modules such as Getopt::Long::Descriptive and Getopt::Long::Modern for simpler usage.

Json

JSON.pm is old and full of slow logic. Use JSON::MaybeXS instead, it is a drop-in replacement in most cases.

List::MoreUtils

List::MoreUtils is a far more complex distribution than it needs to be. Use List::SomeUtils instead, or see List::Util or List::UtilsBy for alternatives.

Mouse

Mouse was created to be a faster version of Moose, a niche that has since been better filled by Moo. Use Moo instead.

Readonly

Readonly.pm is buggy and slow. Use Const::Fast or ReadonlyX instead, or the core pragma constant.

Affiliation

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

Configuration

Occasionally you may find yourself needing to use one of these non-preferred modules, and do not want the warnings. You can do so by putting something like the following in a .perlcriticrc file like this:

    [Community::PreferredAlternatives]
    allowed_modules = Getopt::Std JSON

The same option is offered for Perl::Critic::Policy::Community::DiscouragedModules.
