The first time you run a program under "use Acme::MJD", the module removes all the unsightly printable characters from your source file. The code continues to work exactly as it did before, but now it contains a profound nugget of wisdom from the man...

This module can convert a DateTime object (or any object that can be converted to a DateTime object) to the Modified Julian Day number. See DateTime::Format::Epoch::JD for a description....

• DateTime::Format::Epoch::JD - Convert DateTimes to/from Julian Days

This class assists in implementing a realisation of Terrestrial Time (TT) by interpolation using the "Time::TT::InterpolatingRealisation" class. Many such time scales are defined by tables of data giving the difference between TAI and the time scale ...

• Time::TT - Terrestrial Time and its realisations

The units program converts quantities expressed in various scales to their equivalents in other scales. The units program can only handle multiplicative or affine scale changes. It works interactively by prompting the user for input: You have: meters...

This section of the FAQ answers questions related to manipulating numbers, dates, strings, arrays, hashes, and miscellaneous data issues....

This file documents version 0.120 of EZDBI. It assumes that you already know the basics of SQL. It is not a(n) SQL tutorial. EZDBI provides a simple and convenient interface to most common SQL databases. It requires that you have installed the DBI mo...

• IT::perlreftut

DateTime is a class for the representation of date/time combinations, and is part of the Perl DateTime project. For details on this project please see <http://datetime.perl.org/>. The DateTime site has a FAQ which may help answer many "how do I do X?...

This document is an attempt to shine some light on the guts of the regex engine and how it works. The regex engine represents a significant chunk of the perl codebase, but is relatively poorly understood. This document is a meagre attempt at addressi...

• perlreftut - Mark's very short tutorial about references

This is a library for generating form letters, building HTML pages, or filling in templates generally. A `template' is a piece of text that has little Perl programs embedded in it here and there. When you `fill in' a template, you evaluate the little...

• Text::Template::Preprocess - Expand template text with embedded Perl

"Async" executes some code in a separate process and retrieves the result. Since the code is running in a separate process, your main program can continue with whatever it was doing while the separate code is executing. This separate code is called a...

This module can be used to create index files for jsFind, powerful tool for adding a search engine to a CDROM archive or catalog without requiring the user to install anything. Main difference between this module and scripts delivered with jsFind are...

`Memoizing' a function makes it faster by trading space for time. It does this by caching the return values of the function in a table. If you call the function again with the same arguments, "memoize" jumps in and gives you the value out of the tabl...

• Memoize::Expire - Plug-in module for automatic expiration of memoized values
• Memoize::ExpireTest - test for Memoize expiration semantics

Class for manipulating and transforming astronomical coordinates. Can handle the following coordinate types: + Equatorial RA/Dec, galactic (including proper motions and parallax) + Planets + Comets/Asteroids + Fixed locations in azimuth and elevation...

• Astro::Coords::Elements - Specify astronomical coordinates using orbital elements
• Astro::Coords::Interpolated - Specify astronomical coordinates using two reference positions

"FakeHash" simulates the behavior of a Perl hash variable, maintaining a synthetic data structure that mirrors the true data structure inside of Perl. This can be used to investigate hash performance or behavior. For example, see the "FakeHash::DrawH...

(The documentation is probably not up to date.) Starfish is a system for Perl-based text-embedded programming and preprocessing, which relies on a unifying regular expression rewriting methodology. If you know Perl and php, you probably know the basi...

"Tie::File" represents a regular text file as a Perl array. Each element in the array corresponds to a record in the file. The first line of the file is element 0 of the array; the second line is element 1, and so on. The file is *not* loaded into me...
