This module is a data dumper optimized for logging of arbitrary parameters.

IO::All combines all of the best Perl IO modules into a single nifty object oriented interface to greatly simplify your everyday Perl IO idioms. It exports a single function called io, which returns a new IO::All object. And that object can do it all!

File locking in Perl is usually done using the flock function. Unfortunately, this only allows locks on whole files and is often implemented in terms of the flock(2) system function which has some shortcomings (especially concerning locks on remotely mounted file systems) and slightly different behaviour than fcntl(2).

Getopt::Long::Descriptive is yet another Getopt library. It's built atop Getopt::Long, and gets a lot of its features, but tries to avoid making you think about its huge array of options. It also provides usage (help) messages, data validation, and a few other useful features.

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"))))

Lingua::Translit can be used to convert text from one writing system to another, based on national or international transliteration tables. Where possible a reverse transliteration is supported.

Devel::Symdump provides access to the perl symbol table.

One recurring problem in modules that use Scalar::Util's weaken function is that it is not present in the pure-perl variant. If Scalar::Util is not available at all, it will issue a normal dependency on the module. However, if Scalar::Util is relatively new ( it is >= 1.19 ) and the module does not have weaken, the install will bail out altogether with a long error encouraging the user to seek support.

A String::Util module of small, handy functions for processing strings in various ways.

This module builds on MooseX::Types::DateTime to add additional custom types and coercions. Since it builds on an existing type, all coercions and constraints are inherited.

This module attempts to work around people calling UNIVERSAL::can() as a function, which it is not.

This module attempts to emulate the behavior of Class::Accessor::Fast as accurately as possible using the Moose attribute system. The public API of Class::Accessor::Fast is wholly supported, but the private methods are not.

YAML::Syck provides a Perl interface to the libsyck data serialization library. It exports the Dump and Load functions for converting Perl data structures to YAML strings, and the other way around.

This package provides a Perl module for TrueType/OpenType font hacking. It supports reading, processing and writing of the following tables: GDEF, GPOS, GSUB, LTSH, OS/2, PCLT, bsln, cmap, cvt, fdsc, feat, fpgm, glyf, hdmx, head, hhea, hmtx, kern, loca, maxp, mort, name, post, prep, prop, vhea, vmtx and the reading and writing of all other table types.

This module converts Perl data structures to JSON and vice versa.

Role::Tiny is a minimalist role composition tool.

Spiffy is a framework and methodology for doing object oriented (OO) programming in Perl. Spiffy combines the best parts of Exporter.pm, base.pm, mixin.pm and SUPER.pm into one magic foundation class. It attempts to fix all the nits and warts of traditional Perl OO, in a clean, straightforward and (perhaps someday) standard way. Spiffy borrows ideas from other OO languages like Python, Ruby, Java and Perl 6.

This package lets you declare types using short names, but behind the scenes it namespaces all your type declarations, effectively prevent name clashes between packages.

This module provides a Log::Any adapter to send log messages to screen, with colors and some other features.

Socket::MsgHdr provides advanced socket messaging operations via sendmsg and recvmsg.

It also allows manipulating ancillary data or so-called control information (cmsghdr). This ancillary data may be used for file descriptor passing, IPv6 operations, and a host of implementation-specific extensions.

This package provides tools for inspecting subroutines in Perl.

This package allows you to make the file verdict (i.e., ok, NOT OK) colorful in test outputs.

Devel::GlobalDestruction provides a function returning the equivalent of "${^GLOBAL_PHASE} eq 'DESTRUCT'" for older perls.

This class provides several methods for host name resolution. It is designed to be used with event loops. Names are resolved by your system's native getaddrinfo(3) implementation, called in a separate thread to avoid blocking the entire application. Threading overhead is limited by using system threads instead of Perl threads.
