XML::Writer is a simple Perl module for writing XML documents: it takes care of constructing markup and escaping data correctly. By default, it also performs a significant amount of well-formedness checking on the output to make certain (for example) that start and end tags match, that there is exactly one document element, and that there are not duplicate attribute names.

Moo is an extremely light-weight Object Orientation system. It allows one to concisely define objects and roles with a convenient syntax that avoids the details of Perl's object system. Moo contains a subset of Moose and is optimised for rapid startup.

This package contains a selection of subroutines that people have expressed would be nice to have in the perl core, but the usage would not really be high enough to warrant the use of a keyword, and the size so small such that being individual extensions would be wasteful.

This module intends to be a better Text::Wrap module. This module is needed to support multibyte character encodings such as UTF-8, EUC-JP, EUC-KR, GB2312, and Big5. This module also supports characters with irregular widths, such as combining characters (which occupy zero columns on terminal, like diacritical marks in UTF-8) and fullwidth characters (which occupy two columns on terminal, like most of east Asian characters). Also, minimal handling of languages which doesn't use whitespaces between words (like Chinese and Japanese) is supported.

This module provides user-defined Unicode properties that deal with width status of East Asian characters, as specified in Unicode® Standard Annex #11.

PLS is a Perl language server that implements a subset of the Language Server Protocol for the Perl language. Features currently implemented are:

• Go to definition (for packages, subroutines, and variables)

• Listing all symbols in a document

• Hovering to show documentation

• Signature help (showing parameters for a function as you type)

• Formatting

• Range formatting

• Auto-completion

• Syntax checking

• Linting (using perlcritic)

• Sorting imports

To use this language with Emacs, you can configure Eglot like so:

(add-hook 'perl-mode-hook 'eglot-ensure)
(setq eglot-server-programs '((perl-mode . ("pls"))))

Crypt::PasswdMD5 provides various crypt()-compatible interfaces to the MD5-based crypt() function found in various *nixes. It is based on the implementation found on FreeBSD 2.2.[56]-RELEASE.

Carp::Assert is intended for a purpose like the ANSI C library assert.h.

CPAN::DistnameInfo uses heuristics to extract the distribution name and version from filenames.

The mix_class function provided by this module dynamically generates anonymous classes with specified inheritance. This is useful where an incomplete class requires use of a mixin in order to become instantiable.

Path::Class is a module for manipulation of file and directory specifications in a cross-platform manner.

This module provides a simple but extensible way of having plugins for your Perl module.

Number::Compare compiles a simple comparison to an anonymous subroutine, which you can call with a value to be tested against.

The Carp routines are useful in your own modules because they act like die() or warn(), but with a message which is more likely to be useful to a user of your module. In the case of cluck, confess, and longmess that context is a summary of every call in the call-stack. For a shorter message you can use carp or croak which report the error as being from where your module was called. There is no guarantee that that is where the error was, but it is a good educated guess.

Devel::Caller provides meatier version of caller.

This module is an implementation of the BGP-4 inter-domain routing protocol. It encapsulates all of the functionality needed to establish and maintain a BGP peering session and exchange routing update information with the peer. It aims to provide a simple API to the BGP protocol for the purposes of automation, logging, monitoring, testing, and similar tasks using the power and flexibility of perl. The module does not implement the functionality of a RIB (Routing Information Base) nor does it modify the kernel routing table of the host system. However, such operations could be implemented using the API provided by the module.

shell-quote lets you pass arbitrary strings through the shell so that they won't be changed.

This module provides functions to encode and decode UTF-8 encoding form as specified by Unicode and ISO/IEC 10646:2011.

Devel::CheckLib is a Perl module that checks whether a particular C library and its headers are available. You can also check for the presence of particular functions in a library, or even that those functions return particular results.

This module provides a facility for creating non-modifiable variables in Perl. This is useful for configuration files, headers, etc. It can also be useful as a development and debugging tool for catching updates to variables that should not be changed.

Text::Glob implements glob(3) style matching that can be used to match against text, rather than fetching names from a file system. If you want to do full file globbing use the File::Glob module instead.

PAR::Dist is a toolkit to create and manipulate PAR distributions.

Stream::Buffered is a buffer class to store arbitrary length of byte strings and then get a seekable filehandle once everything is buffered. It uses PerlIO and/or temporary file to save the buffer depending on the length of the size.

Log::Report combines three tasks which are closely related in one: logging, exceptions, and translations.
