#NAME

Pod::LaTeX - Convert Pod data to formatted Latex

#SYNOPSIS

use Pod::LaTeX;
my $parser = Pod::LaTeX->new ( );

$parser->parse_from_filehandle;

$parser->parse_from_file ('file.pod', 'file.tex');

#DESCRIPTION

Pod::LaTeX is a module to convert documentation in the Pod format into Latex. The pod2latex command uses this module for translation.

Pod::LaTeX is a derived class from Pod::Select.

#OBJECT METHODS

The following methods are provided in this module. Methods inherited from Pod::Select are not described in the public interface.

#Data Accessors

The following methods are provided for accessing instance data. These methods should be used for accessing configuration parameters rather than assuming the object is a hash.

Default values can be supplied by using these names as keys to a hash of arguments when using the new() constructor.

#AddPreamble

Logical to control whether a latex preamble is to be written. If true, a valid latex preamble is written before the pod data is written. This is similar to:

\documentclass{article}
\begin{document}

but will be more complicated if table of contents and indexing are required. Can be used to set or retrieve the current value.

$add = $parser->AddPreamble();
$parser->AddPreamble(1);

If used in conjunction with AddPostamble a full latex document will be written that could be immediately processed by latex.

#AddPostamble

Logical to control whether a standard latex ending is written to the output file after the document has been processed. In its simplest form this is simply:

\end{document}

but can be more complicated if an index is required. Can be used to set or retrieve the current value.

$add = $parser->AddPostamble();
$parser->AddPostamble(1);

If used in conjunction with AddPreaamble a full latex document will be written that could be immediately processed by latex.

#Head1Level

The latex sectioning level that should be used to correspond to a pod =head1 directive. This can be used, for example, to turn a =head1 into a latex subsection. This should hold a number corresponding to the required position in an array containing the following elements:

[0] chapter
[1] section
[2] subsection
[3] subsubsection
[4] paragraph
[5] subparagraph

Can be used to set or retrieve the current value:

$parser->Head1Level(2);
$sect = $parser->Head1Level;

Setting this number too high can result in sections that may not be reproducible in the expected way. For example, setting this to 4 would imply that =head3 do not have a corresponding latex section (=head1 would correspond to a paragraph).

A check is made to ensure that the supplied value is an integer in the range 0 to 5.

Default is for a value of 1 (i.e. a section).

#Label

This is the label that is prefixed to all latex label and index entries to make them unique. In general, pods have similarly titled sections (NAME, DESCRIPTION etc) and a latex label will be multiply defined if more than one pod document is to be included in a single latex file. To overcome this, this label is prefixed to a label whenever a label is required (joined with an underscore) or to an index entry (joined by an exclamation mark which is the normal index separator). For example, \label{text} becomes \label{Label_text}.

Can be used to set or retrieve the current value:

$label = $parser->Label;
$parser->Label($label);

This label is only used if UniqueLabels is true. Its value is set automatically from the NAME field if ReplaceNAMEwithSection is true. If this is not the case it must be set manually before starting the parse.

Default value is undef.

#LevelNoNum

Control the point at which latex section numbering is turned off. For example, this can be used to make sure that latex sections are numbered but subsections are not.

Can be used to set or retrieve the current value:

$lev = $parser->LevelNoNum;
$parser->LevelNoNum(2);

The argument must be an integer between 0 and 5 and is the same as the number described in Head1Level method description. The number has nothing to do with the pod heading number, only the latex sectioning.

Default is 2. (i.e. latex subsections are written as subsection* but sections are numbered).

#MakeIndex

Controls whether latex commands for creating an index are to be inserted into the preamble and postamble

$makeindex = $parser->MakeIndex;
$parser->MakeIndex(0);

Irrelevant if both AddPreamble and AddPostamble are false (or equivalently, UserPreamble and UserPostamble are set).

Default is for an index to be created.

#ReplaceNAMEwithSection

This controls whether the NAME section in the pod is to be translated literally or converted to a slightly modified output where the section name is the pod name rather than "NAME".

If true, the pod segment

=head1 NAME

pod::name - purpose

=head1 SYNOPSIS

is converted to the latex

\section{pod::name\label{pod_name}\index{pod::name}}

Purpose

\subsection*{SYNOPSIS\label{pod_name_SYNOPSIS}%
             \index{pod::name!SYNOPSIS}}

(dependent on the value of Head1Level and LevelNoNum). Note that subsequent head1 directives translate to subsections rather than sections and that the labels and index now include the pod name (dependent on the value of UniqueLabels).

The Label is set from the pod name regardless of any current value of Label.

$mod = $parser->ReplaceNAMEwithSection;
$parser->ReplaceNAMEwithSection(0);

Default is to translate the pod literally.

#StartWithNewPage

If true, each pod translation will begin with a latex \clearpage.

$parser->StartWithNewPage(1);
$newpage = $parser->StartWithNewPage;

Default is false.

#TableOfContents

If true, a table of contents will be created. Irrelevant if AddPreamble is false or UserPreamble is set.

$toc = $parser->TableOfContents;
$parser->TableOfContents(1);

Default is false.

#UniqueLabels

If true, the translator will attempt to make sure that each latex label or index entry will be uniquely identified by prefixing the contents of Label. This allows multiple documents to be combined without clashing common labels such as DESCRIPTION and SYNOPSIS

$parser->UniqueLabels(1);
$unq = $parser->UniqueLabels;

Default is true.

#UserPreamble

User supplied latex preamble. Added before the pod translation data.

If set, the contents will be prepended to the output file before the translated data regardless of the value of AddPreamble. MakeIndex and TableOfContents will also be ignored.

#UserPostamble

User supplied latex postamble. Added after the pod translation data.

If set, the contents will be prepended to the output file after the translated data regardless of the value of AddPostamble. MakeIndex will also be ignored.

#NOTES

Compatible with latex2e only. Can not be used with latex v2.09 or earlier.

A subclass of Pod::Select so that specific pod sections can be converted to latex by using the select method.

Some HTML escapes are missing and many have not been tested.
