This class lets you build groups of accessors that will call different getters and setters.

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.

Term::ProgressBar::Simple tells you how much work has been done, how much is left to do, and estimate how long it will take.

Alien::SDL can be used to detect and get configuration settings from an installed SDL and related libraries. Based on your platform it offers the possibility to download and install prebuilt binaries or to build SDL & co.: from source codes.

This is a module for computing the difference between two files, two strings, or any other two lists of things. It uses an intelligent algorithm similar to (or identical to) the one used by the Unix "diff" program. It is guaranteed to find the *smallest possible* set of differences.

This module is optionally used by Type::Tiny to provide faster, C-based implementations of some type constraints. This package has only core dependencies, and does not depend on Type::Tiny, so other data validation frameworks might also consider using it.

Authen::DecHpwd implements the SYS$HASH_PASSWORD password hashing function from VMS (also known as LGI$HPWD) and some associated VMS username and password handling functions. The password hashing function is implemented in XS with a pure Perl backup version for systems that cannot handle XS.

This module replaces the standard localtime and gmtime functions with implementations that return objects. It does so in a backwards-compatible manner, so that using these functions as documented will still work as expected.

Class::Method::Modifiers provides three modifiers: before, around, and after. before and after are run just before and after the method they modify, but can not really affect that original method. around is run in place of the original method, with a hook to easily call that original method.

This module provides two new keywords, fun and method, for defining functions and methods with parameter lists. At minimum this saves you from having to unpack @_ manually, but this module can do much more.

Log::Log4perl lets you remote-control and fine-tune the logging behaviour of your system from the outside. It implements the widely popular (Java-based) Log4j logging package in pure Perl.

This package provides procedures to get and set resource limits like getrlimit and setpriority.

"require EXPR" only accepts Class/Name.pm style module names, not Class::Name. For that, this module provides "load_class 'Class::Name'".

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).

This module handles parsing, modifying and creating configuration files of the style used by the Git version control system.

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.

This module exports two functions, nsort and ncmp; they are used in implementing a "natural sorting" algorithm. Under natural sorting, numeric substrings are compared numerically, and other word-characters are compared lexically.

IO::String is an IO::File (and IO::Handle) compatible class that reads or writes data from in-core strings.

The IPC::Run3 module allows you to run a subprocess and redirect stdin, stdout, and/or stderr to files and perl data structures. It aims to satisfy 99% of the need for using system, qx, and open3 with a simple, extremely Perlish API and none of the bloat and rarely used features of IPC::Run.

String::Format lets you define arbitrary printf-like format sequences to be expanded. This module would be most useful in configuration files and reporting tools, where the results of a query need to be formatted in a particular way. It was inspired by mutt's .

This module implements Spreadsheet::XLSX parsing Microsoft Excel 2007 xlsx files.

This module exposes interpreter threads to the Perl level.

The Term::Animation Perl module provides a framework to produce sprite animations using ASCII art. Each ASCII 'sprite' is given one or more frames, and placed into the animation as an 'animation entity'. An animation entity can have a callback routine that controls the position and frame of the entity. The module can also do collision detection between entities.

Bit::Vector is an efficient C library which allows you to handle bit vectors, sets (of integers), "big integer arithmetic" and boolean matrices, all of arbitrary sizes. The package also includes an object-oriented Perl module for accessing the C library from Perl, and optionally features overloaded operators for maximum ease of use. The C library can nevertheless be used stand-alone, without Perl.
