Perl::Critic::Policy::Freenode::DiscouragedModules - Various modules discouraged from use

Various modules are discouraged by the denizens of #perl on Freenode IRC, for various reasons which may include: buggy behavior, cruft, performance problems, maintainer issues, or simply better modern replacements. This is a high severity complement to Perl::Critic::Freenode::Policy::PreferredAlternatives.

AnyEvent's author refuses to use public bugtracking and actively breaks interoperability. POE, IO::Async, and Mojo::IOLoop are widely used and interoperable async event loops.

Any::Moose is deprecated. Use Moo instead.

Class::DBI is an ancient database ORM <https://en.wikipedia.org/wiki/Object-relational_mapping> abstraction layer which is buggy and abandoned. See DBIx::Class for a more modern DBI-based ORM, or Mad::Mapper for a Mojolicious-style ORM.

CGI

CGI.pm is an ancient module for communicating via the CGI protocol, with tons of bad practices and cruft. Use a modern framework such as those based on Plack (Web::Simple, Dancer2, Catalyst) or Mojolicious, they can still be served via CGI if you choose.

Coro no longer works on perl 5.22, you need to use the author's forked version of Perl. Avoid at all costs.

Error.pm is overly magical and discouraged by its maintainers. Try Throwable for exception classes in Moo/Moose, or Exception::Class otherwise. Try::Tiny or Try are recommended for the "try"/"catch" syntax.

File::Slurp gets file encodings all wrong, line endings on win32 are messed up, and it was written before layers were properly added. Use File::Slurper, "slurp" in Path::Tiny, "slurp" in Data::Munge, or "slurp" in Mojo::File.

HTML::Template is an old and buggy module, try Template::Toolkit, HTML::Zoom, or Text::Template instead, or HTML::Template::Pro if you must use the same syntax.

IO::Socket::INET6 is an old attempt at an IPv6 compatible version of IO::Socket::INET, but has numerous issues and is discouraged by the maintainer in favor of IO::Socket::IP, which transparently creates IPv4 and IPv6 sockets.

JSON::Any is deprecated. Use JSON::MaybeXS instead.

JSON::XS

JSON::XS's author refuses to use public bugtracking and actively breaks interoperability. Cpanel::JSON::XS is a fork with several bugfixes and a more collaborative maintainer. See also JSON::MaybeXS.

Net::IRC is an ancient module implementing the IRC protocol. Use a modern event-loop-based module instead. Choices are POE::Component::IRC (used for Bot::BasicBot), Net::Async::IRC, and Mojo::IRC.

Switch.pm is a buggy and outdated source filter which can cause any number of strange errors, in addition to the problems with smart-matching shared by its replacement, "The 'switch' feature" in feature ("given"/"when"). Try Switch::Plain instead.

XML::Simple tries to coerce complex XML documents into perl data structures. This leads to overcomplicated structures and unexpected behavior. Use a proper DOM parser instead like XML::LibXML, XML::TreeBuilder, XML::Twig, or Mojo::DOM.

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

This policy is not configurable except for the standard options.
