.SH "NAME"
Perl::Critic::Policy::Freenode::DiscouragedModules \- Various modules
discouraged from use
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Various modules are discouraged by the denizens of #perl on Freenode \s-1IRC,\s0 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::Policy::Freenode::PreferredAlternatives.
.SH "MODULES"
.IX Header "MODULES"
.SS "AnyEvent"
.IX Subsection "AnyEvent"
AnyEvent's author refuses to use public bugtracking and actively breaks
interoperability. \s-1POE\s0, IO::Async, and Mojo::IOLoop are widely used and
interoperable async event loops.
.SS "Any::Moose"
.IX Subsection "Any::Moose"
Any::Moose is deprecated. Use Moo instead.
.SS "Class::DBI"
.IX Subsection "Class::DBI"
Class::DBI is an ancient database \s-1ORM\s0 <https://en.wikipedia.org/wiki/Object-relational_mapping>
abstraction layer which is buggy and abandoned. See DBIx::Class for a more
modern \s-1DBI\s0\-based \s-1ORM,\s0 or Mad::Mapper for a Mojolicious\-style \s-1ORM.\s0
.SS "\s-1CGI\s0"
.IX Subsection "CGI"
\&\s-1CGI\s0.pm is an ancient module for communicating via the \s-1CGI\s0 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 \s-1CGI\s0 if you choose.
.SS "Coro"
.IX Subsection "Coro"
Coro abuses Perl internals in an unsupported way. Consider Future and
Future::AsyncAwait in combination with event loops for similar semantics.
.SS "Error"
.IX Subsection "Error"
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 Syntax::Keyword::Try are recommended for the
\&\f(CW\*(C`try\*(C'\fR/\f(CW\*(C`catch\*(C'\fR syntax.
.SS "FindBin"
.IX Subsection "FindBin"
FindBin is often used to retrieve the absolute path to the directory
containing the initially executed script, a mechanism which is not always
logically clear. Additionally, it has serious bugs on old Perls and can't be
updated from \s-1CPAN\s0 to fix them. The Path::This module provides similar
variables and constants based on the absolute path to the current source file.
The lib::relative module resolves passed relative paths to the current
source file for the common case of adding local module include directories.
Each of these documents examples of achieving the same behavior with core
modules.
.SS "File::Slurp"
.IX Subsection "File::Slurp"
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,
\&\*(L"slurp\*(R" in Path::Tiny, \*(L"slurp\*(R" in Data::Munge, or \*(L"slurp\*(R" in Mojo::File.
.SS "HTML::Template"
.IX Subsection "HTML::Template"
HTML::Template is an old and buggy module, try Template::Toolkit,
Mojo::Template, or Text::Xslate instead, or HTML::Template::Pro if you
must use the same syntax.
.SS "IO::Socket::INET6"
.IX Subsection "IO::Socket::INET6"
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.
.SS "JSON::Any"
.IX Subsection "JSON::Any"
JSON::Any is deprecated. Use JSON::MaybeXS instead.
.SS "\s-1JSON::XS\s0"
.IX Subsection "JSON::XS"
\&\s-1JSON::XS\s0'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.
.SS "Net::IRC"
.IX Subsection "Net::IRC"
Net::IRC is an ancient module implementing the \s-1IRC\s0 protocol. Use a modern
event-loop-based module instead. Choices are POE::Component::IRC (used for
Bot::BasicBot), Net::Async::IRC, and Mojo::IRC.
.SS "Switch"
.IX Subsection "Switch"
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, \*(L"The 'switch' feature\*(R" in feature (\f(CW\*(C`given\*(C'\fR/\f(CW\*(C`when\*(C'\fR). Try
Switch::Plain instead.
.SS "XML::Simple"
.IX Subsection "XML::Simple"
XML::Simple tries to coerce complex \s-1XML\s0 documents into perl data structures.
This leads to overcomplicated structures and unexpected behavior. Use a proper
\&\s-1DOM\s0 parser instead like XML::LibXML, XML::TreeBuilder, XML::Twig, or
Mojo::DOM.
.SH "AFFILIATION"
.IX Header "AFFILIATION"
This policy is part of Perl::Critic::Freenode.
.SH "CONFIGURATION"
.IX Header "CONFIGURATION"
This policy is not configurable except for the standard options.
