Non-Description This module is not for drawing or rendering any sort of *graphics* or *images*, business, visualization, or otherwise. Description Instead, this module is for creating *abstract data structures* called graphs, and for doing various op...

Perl runs on numerous operating systems. While most of them share much in common, they also have their own unique features. This document is meant to help you to find out what constitutes portable Perl code. That way once you make a decision to write...

The Storable package brings persistence to your Perl data structures containing SCALAR, ARRAY, HASH or REF objects, i.e. anything that can be conveniently stored to disk and retrieved at a later time. It can be used in the regular procedural way by c...

The "Time::HiRes" module implements a Perl interface to the "usleep", "nanosleep", "ualarm", "gettimeofday", and "setitimer"/"getitimer" system calls, in other words, high resolution time and timers. See the "EXAMPLES" section below and the test scri...

"Math::Trig" defines many trigonometric functions not defined by the core Perl which defines only the "sin()" and "cos()". The constant pi is also defined as are a few convenience functions for angle conversions, and *great circle formulas* for spher...

• Math::Complex - complex numbers and associated mathematical functions

"IO::Zlib" provides an IO:: style interface to Compress::Zlib and hence to gzip/zlib compressed files. It provides many of the same methods as the IO::Handle interface. Starting from IO::Zlib version 1.02, IO::Zlib can also use an external gzip comma...

By default, Time::PT stores time descriptions precise to 60ths- of-a-second (0.016667 seconds). The groundwork has been laid for sub-millisecond precision to be included later. This module has been adapted from the Time::Piece module written by Matt ...

• Time::Fields - abstract objects to store distinct time fields
• Time::Frame - objects to store a length of time

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 localtime/gmtime in the way documented in perlfunc will still return what you ex...

String::Approx lets you match and substitute strings approximately. With this you can emulate errors: typing errorrs, speling errors, closely related vocabularies (colour color), genetic mutations (GAG ACT), abbreviations (McScot, MacScot). NOTE: Str...

This module implements a simple bag (multiset) class. A bag may contain one or more instances of elements. One may add and delete one or more instances at a time. If one attempts to delete more instances than there are to delete from, the default beh...

"CPANPLUS::Module" creates objects from the information in the source files. These can then be used to query and perform actions on, like fetching or installing. These objects should only be created internally. For "fake" objects, there's the "CPANPL...

The Devel::CallStack is meant for code developers wondering why their code is running so slow. One possible reason is simply too many subroutine or method calls since they are not cheap in Perl. The Devel::CallStack records the calling stacks, how ma...

As described in http://www.dangermouse.net/esoteric/ook.html Since the word "ook" can convey entire ideas, emotions, and abstract thoughts depending on the nuances of inflection, Ook! has no need of comments. The code itself serves perfectly well to ...
