=head1 NAME

HTML::GenToc - Generate a Table of Contents for HTML documents.

=head1 VERSION

version 3.20

=head1 SYNOPSIS

  use HTML::GenToc;

  # create a new object
  my $toc = new HTML::GenToc();

  my $toc = new HTML::GenToc(title=>"Table of Contents",
			  toc_entry=>{
			    H1=>1,
			    H2=>2
			  },
			  toc_end=>{
			    H1=>'/H1',
			    H2=>'/H2'
			  }
    );

  # generate a ToC from a file
  $toc->generate_toc(input=>$html_file,
		     footer=>$footer_file,
		     header=>$header_file
    );


=head1 DESCRIPTION

HTML::GenToc generates anchors and a table of contents for
HTML documents.  Depending on the arguments, it will insert
the information it generates, or output to a string, a separate file
or STDOUT.

While it defaults to taking H1 and H2 elements as the significant
elements to put into the table of contents, any tag can be defined
as a significant element.  Also, it doesn't matter if the input
HTML code is complete, pure HTML, one can input pseudo-html
or page-fragments, which makes it suitable for using on templates
and HTML meta-languages such as WML.

Also included in the distrubution is hypertoc, a script which uses the
module so that one can process files on the command-line in a
user-friendly manner.

=head1 DETAILS

The ToC generated is a multi-level level list containing links to the
significant elements. HTML::GenToc inserts the links into the ToC to
significant elements at a level specified by the user.

B

If H1s are specified as level 1, than they appear in the first
level list of the ToC. If H2s are specified as a level 2, than
they appear in a second level list in the ToC.

Information on the significant elements and what level they should occur
are passed in to the methods used by this object, or one can use the
defaults.

There are two phases to the ToC generation.  The first phase is to
put suitable anchors into the HTML documents, and the second phase
is to generate the ToC from HTML documents which have anchors
in them for the ToC to link to.

For more information on controlling the contents of the created ToC, see
L.

HTML::GenToc also supports the ability to incorporate the ToC into the HTML
document itself via the B option.  See L for more
information.

In order for HTML::GenToc to support linking to significant elements,
HTML::GenToc inserts anchors into the significant elements.  One can
use HTML::GenToc as a filter, outputing the result to another file,
or one can overwrite the original file, with the original backed
up with a suffix (default: "org") appended to the filename.
One can also output the result to a string.

=head1 METHODS

Default arguments can be set when the object is created, and overridden
by setting arguments when the generate_toc method is called.
Arguments are given as a hash of arguments.

=head2 generate_toc

    $toc->generate_toc(outfile=>"index2.html");

    my $result_str = $toc->generate_toc(to_string=>1);

Generates a table of contents for the significant elements in the HTML
documents, optionally generating anchors for them first.

B

=over

=item bak

bak => I

If the input file/files is/are being overwritten (B is on), copy
the original file to "I.I".  If the value is empty, B
backup file will be created.
(default:org)

=item debug

debug => 1

Enable verbose debugging output.  Used for debugging this module;
in other words, don't bother.
(default:off)

=item entrysep

entrysep => I

Separator string for non- item entries
(default: ", ")

=item filenames

filenames => \@filenames

The filenames to use when creating table-of-contents links.
This overrides the filenames given in the B option,
and is expected to have exactly the same number of elements.
This can also be used when passing in string-content to the B
option, to give a (fake) filename to use for the links relating
to that content.

=item footer

footer => I

Either the filename of the file containing footer text for ToC;
or a string containing the footer text.

=item header

header => I

Either the filename of the file containing header text for ToC;
or a string containing the header text.

=item ignore_only_one

ignore_only_one => 1

If there would be only one item in the ToC, don't make a ToC.

=item ignore_sole_first

ignore_sole_first => 1

If the first item in the ToC is of the highest level,
AND it is the only one of that level, ignore it.
This is useful in web-pages where there is only one H1 header
but one doesn't know beforehand whether there will be only one.

=item inline

inline => 1

Put ToC in document at a given point.
See L for more information.

=item input

input => \@filenames

input => $content

This is expected to be either a reference to an array of filenames,
or a string containing content to process.

The three main uses would be:

=over

=item (a)

you have more than one file to process, so pass in multiple filenames

=item (b)

you have one file to process, so pass in its filename as the only array item

=item (c)

you have HTML content to process, so pass in just the content as a string

=back

(default:undefined)

=item notoc_match

notoc_match => I

If there are certain individual tags you don't wish to include in the
table of contents, even though they match the "significant elements",
then if this pattern matches contents inside the tag (not the body),
then that tag will not be included, either in generating anchors nor in
generating the ToC.  (default: C)

=item ol

ol => 1

Use an ordered list for level 1 ToC entries.

=item ol_num_levels

ol_num_levels => 2

The number of levels deep the OL listing will go if B is true.
If set to zero, will use an ordered list for all levels.
(default:1)

=item overwrite

overwrite => 1

Overwrite the input file with the output.
(default:off)

=item outfile

outfile => I

File to write the output to.  This is where the modified HTML
output goes to.  Note that it doesn't make sense to use this option if you
are processing more than one file.  If you give '-' as the filename, then
output will go to STDOUT.
(default: STDOUT)

=item quiet

quiet => 1

Suppress informative messages. (default: off)

=item textonly

textonly => 1

Use only text content in significant elements.

=item title

title => I

Title for ToC page (if not using B or B or B)
(default: "Table of Contents")

=item toc_after

toc_after => \%toc_after_data

%toc_after_data = { I => I,
    I => I
    };

toc_after => { H2=>'' }

For defining layout of significant elements in the ToC.

This expects a reference to a hash of
tag=>suffix pairs.

The I is the HTML tag which marks the start of the element.  The
I is what is required to be appended to the Table of Contents
entry generated for that tag.

(default: undefined)

=item toc_before

toc_before => \%toc_before_data

%toc_before_data = { I => I,
    I => I
    };

toc_before=>{ H2=>'' }

For defining the layout of significant elements in the ToC.  The I
is the HTML tag which marks the start of the element.  The I is
what is required to be prepended to the Table of Contents entry
generated for that tag.

(default: undefined)

=item toc_end

toc_end => \%toc_end_data

%toc_end_data = { I => I,
    I => I
    };

toc_end => { H1 => '/H1', H2 => '/H2' }

For defining significant elements.  The I is the HTML tag which
marks the start of the element.  The I the HTML tag which marks
the end of the element.  When matching in the input file, case is
ignored (but make sure that all your I options referring to the
same tag are exactly the same!).

=item toc_entry

toc_entry => \%toc_entry_data

%toc_entry_data = { I => I,
    I => I
    };

toc_entry => { H1 => 1, H2 => 2 }

For defining significant elements.  The I is the HTML tag which marks
the start of the element.  The I is what level the tag is considered
to be.  The value of I must be numeric, and non-zero. If the value
is negative, consective entries represented by the significant_element will
be separated by the value set by B option.

=item toclabel

toclabel => I

HTML text that labels the ToC.  Always used.
(default: "Table of Contents")

=item toc_tag

toc_tag => I

If a ToC is to be included inline, this is the pattern which is used to
match the tag where the ToC should be put.  This can be a start-tag, an
end-tag or a comment, but the E should be left out; that is, if you
want the ToC to be placed after the BODY tag, then give "BODY".  If you
want a special comment tag to make where the ToC should go, then include
the comment marks, for example: "!--toc--" (default:BODY)

=item toc_tag_replace

toc_tag_replace => 1

In conjunction with B, this is a flag to say whether the given tag
should be replaced, or if the ToC should be put after the tag.
This can be useful if your toc_tag is a comment and you don't need it
after you have the ToC in place.
(default:false)

=item toc_only

toc_only => 1

Output only the Table of Contents, that is, the Table of Contents plus
the toclabel.  If there is a B or a B, these will also be
output.

If B is false then if there is no B, and B is
not true, then a suitable HTML page header will be output, and if there
is no B and B is not true, then a HTML page footer will
be output.

(default:false)

=item to_string

to_string => 1

Return the modified HTML output as a string.  This I override
other methods of output (unlike version 3.00).  If I is false,
the method will return 1 rather than a string.

=item use_id

use_id => 1

Use id="I" for anchors rather than  anchors.
However if an anchor already exists for a Significant Element, this
won't make an id for that particular element.

=item useorg

useorg => 1

Use pre-existing backup files as the input source; that is, files of the
form I.I  (see B and B).

With the B option, the contents of the given file (or string)
will be prepended before the generated ToC. This allows you to have
introductory text, or any other text, before the ToC.

=over

=item Note:

If you use the B option, make sure the file specified
contains the opening HTML tag, the HEAD element (containing the
TITLE element), and the opening BODY tag. However, these
tags/elements should not be in the header file if the B
option is used. See L for information on what
the header file should contain for inlining the ToC.

=back

With the B option, the contents of the given string will be
prepended before the generated ToC (but after any text taken from a
B file).

With the B option, the contents of the file will be appended
after the generated ToC.

=over

=item Note:

If you use the B, make sure it includes the closing BODY
and HTML tags (unless, of course, you are using the B option).

=back

If the B option is not specified, the appropriate starting
HTML markup will be added, unless the B option is specified.
If the B option is not specified, the appropriate closing
HTML markup will be added, unless the B option is specified.

If you do not want/need to deal with header, and footer, files, then
you are allowed to specify the title, B option, of the ToC file; </td>
