We move from making unnecessary efforts, the exertions of force, to making necessary efforts: the direction of effortlessness. In this the prime maxim is: honor necessity, honor sufficiency.
— Robert Fripp, "The Road to Graceland"
podlators contains Pod::Man and Pod::Text modules which convert POD input to *roff source output, suitable for man pages, or plain text. It also includes several subclasses of Pod::Text for formatted output to terminals with various capabilities. It is the source package for the Pod::Man and Pod::Text modules included with Perl.
POD is the Plain Old Documentation format, the documentation language used for all of Perl's documentation. I learned it to document Perl modules, started using it for Perl scripts as well, and discovered it was the most convenient way I've found to write program documentation. It's extremely simple, well-designed for writing Unix manual pages (and I'm a traditionalist who thinks that any program should have a regular manual page), and easily readable in the raw format by humans.
The translators into text and nroff (for manual pages) included in the Perl distribution had various bugs, however, and used their own ad hoc parsers, so when I started running into those bugs and when a new generic parser (Pod::Parser) was written, I decided to rewrite the two translators that I use the most and fix the bugs that were bothering me. This package is the result.
podlators contains two main modules, Pod::Man and Pod::Text. The former
converts POD into nroff/troff source and the latter into plain text (with
various options controlling some of the formatting). There are also
several subclasses of Pod::Text for generating slightly formatted text
using color or other terminal control escapes, and a general utility
module, Pod::ParseLink, for parsing the POD L<> formatting
sequences. Also included in this package are the pod2text and
pod2man driver scripts.
Both Pod::Text and Pod::Man provide a variety of options for fine-tuning their output. Pod::Man also tries to massage input text where appropriate to produce better output when run through nroff or troff, such as distinguishing between different types of hyphens.
As of Perl 5.6.0, my implementation was included in Perl core, and each release of Perl will have the at-the-time most current version of podlators included. You therefore only need to install this package yourself if you need a newer version than came with Perl (to get some bug fixes, for example).
This module requires Perl 5.10 or later and Pod::Simple 3.26 or later. (Pod::Simple 3.26 was included in Perl 5.17.10.)
The troff/nroff generated by Pod::Man should be compatible with any troff
or nroff implementation with the -man macro set, including mandoc.
It is primarily tested by me under GNU groff, but Perl users send bug
reports for a wide variety of implementations and Pod::Man is used to
generate all of Perl's own manual pages, so hopefully most of the bugs
have been weeded out.
