Pod::LaTeX(3pm)                       Perl Programmers Reference Guide                       Pod::LaTeX(3pm)



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}
             \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 processed by "latex".

           For some pod escapes it may be necessary to include the amsmath package. This is not yet added to
           the preamble automatically.

       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 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.
