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 configura-
tion 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}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\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 pro-
cessed by "latex".
perl v5.8.8 2005-02-05 1
Pod::LaTeX(3p) Perl Programmers Reference Guide Pod::LaTeX(3p)
For some pod escapes it may be necessary to include the
amsmath package. This is not yet added to the preamble
automaatically.
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 a 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 pro-
cessed 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 follow-
ing 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 exam-
ple, 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 exclama-
tion 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
perl v5.8.8 2005-02-05 3
Pod::LaTeX(3p) Perl Programmers Reference Guide Pod::LaTeX(3p)
"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 "LevelNo-
Num"). 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
perl v5.8.8 2005-02-05 4
Pod::LaTeX(3p) Perl Programmers Reference Guide Pod::LaTeX(3p)
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 iden-
tified by prefixing the contents of "Label". This allows
multiple documents to be combined without clashing com-
mon 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.
