=head1 CONFIGURABLE PACKAGE VARIABLES
=over
=item C<%bisacsubjects>
A mapping of lowercase BISAC codes and text descriptions to standard
capitalized text descriptions. As BISG claims copyright on this and
does not allow the lists to be redistributed, this list must be
downloaded and cached locally via C<ebook dlbisac> before it is
available.
Running the unit tests will cause this to happen automatically.
=item C<%bisactolc>
An extremely incomplete mapping of lowercase BISAC codes and text
descriptions to Library of Congress standard subjects.
=item C<%booktypes>
A hash mapping all-lowercase terms to a standard vocabulary to be used
in <dc:type> elements.
=item C<%dcelements12>
A tied IxHash mapping an all-lowercase list of Dublin Core metadata
element names to the capitalization dictated by the OEB 1.2
specification, used by the fix_oeb12() and fix_oeb12_dcmeta() methods.
Changing the tags in this list will change the tags recognized and
placed inside the <dc-metadata> element.
Order is preserved and significant -- fix_oeb12 will output DC
metadata elements in the same order as in this hash, though order for
tags of the same name is preserved from the input file.
=item C<%dcelements20>
A tied IxHash mapping an all-lowercase list of Dublin Core metadata
element names to the all-lowercase form dictated by the OPF 2.0
specification (which means it maps the all-lowercase tags to
themselves). It is used by the fix_opf20() and fix_opf20_dcmeta()
methods. Changing the tags in this list will change the tags
recognized and placed directly under the <metadata> element.
Order is preserved and significant -- fix_opf20 will output DC
metadata elements in the same order as in this hash, though order for
tags of the same name is preserved from the input file.
=item C<%lcsubjects>
An extremely incomplete mapping of lowercase terms to Library of
Congress subject classifications. This is used for automatic
normalization of subject elements. Every value in the hash has a
lowercase representation of itself as a key in addition to any
aliases.
This MUST NOT contain mappings from BISAC codes or descriptors to
Library of Congress subjects. Use %bisactolc for that.
=item C<%nonxmlentity2char>
This is the %entity2char conversion map from HTML::Entities with the 5
pre-defined XML entities (amp, gt, lt, quot, apos) removed. This is
used during by L</init()> to sanitize the OPF file data before
parsing. This hash can be modified to allow and convert other
non-standard entities to unicode characters. See HTML::Entities for
details.
=item C<%publishermap>
A hash mapping known variants of publisher names to a canonical form,
used by L</fix_publisher()>, and thus also indirectly by
L</fix_misc()>.
Keys should be entered in lowercase. The hash can also be set empty
to prevent fix_publisher() from taking any action at all.
=item C<%referencetypes>
A hash mapping valid OPF 2.0 reference types to themselves, along with
common variants to standard types.
=item C<%relatorcodes>
A hash mapping the MARC Relator Codes (see:
http://www.loc.gov/marc/relators/relacode.html) to their descriptive
names.
=item C<%sexcodes>
A hash normalizing subject tags for erotic fiction, as used by
StoriesOnline, ASSTR, and Literotica, among others.
Unlike the other mappings, this one is *not* lowercased, and the keys
are case-sensitive. The hash maps only to the canonical base code,
but subject normalization will also add a prefix, defaulting to the
BISAC format of 'FICTION / Erotica / '.
=item C<%strangenames>
=item C<%strangefileas>
Hashes mapping mapping known incorrect outputs of name normalization
to correct format. The first handles the main name display, the
second the file-as output.
=item C<$tidycmd>
The tidy executable name. This has to be a fully qualified pathname
if tidy isn't on the path. Defaults to 'tidy'.
=item C<$tidyxhtmlerrors>
The name of the error output file from system_tidy_xhtml(). Defaults
to 'tidyxhtml-errors.txt'
=item C<$tidyxmlerrors>
The name of the error output file from system_tidy_xml(). Defaults to
'tidyxml-errors.txt'
=item C<$tidysafety>
The safety level to use when running tidy (default is 1). Potential
values are:
=over
=item C<$tidysafety < 1>:
No checks performed, no error files kept, works like a clean tidy -m
This setting is DANGEROUS!
=item C<$tidysafety == 1>:
Overwrites original file if there were no errors, but even if there
were warnings. Keeps a log of errors, but not warnings.
=item C<$tidysafety == 2>:
Overwrites original file if there were no errors, but even if there
were warnings. Keeps a log of both errors and warnings.
=item C<$tidysafety == 3>:
Overwrites original file only if there were no errors or warnings.
Keeps a log of both errors and warnings.
=item C<$tidysafety >= 4>:
Never overwrites original file. Keeps a log of both errors and
warnings.
=back
=item C<%validspecs>
A hash mapping valid specification strings to themselves, primarily
used to undefine unrecognized values. Default valid values are 'OEB12'
and 'OPF20'.

Initializes the object from an existing OPF file. If C<$filename> is
specified and exists, the OEB object will be set to read and write to
that file before attempting to initialize. Otherwise, if the object
currently points to an OPF file it will use that name. If there is no
OPF filename data, and C<$filename> was not specified, it will make a
last-ditch attempt to find an OPF file first by looking in
META-INF/container.xml, and if nothing is found there, by looking in
the current directory for a single OPF file.
If no such files or found (or more than one is found), the
initialization croaks.

Returns all of the items in the manifest as a list of hashrefs, with
one hash per manifest item in the order that they appear, where the
hash keys are 'id', 'href', and 'media-type', each returning the
appropriate attribute, if any.
In scalar context, returns the first match, not the last.
=head3 Arguments
C<manifest()> takes four optional named arguments:
=over
=item * C<id> - 'id' attribute to match
=item * C<href> - 'href' attribute to match
=item * C<mtype> - 'media-type' attribute to match
=item * C<logic> - logic to use (valid values are 'and' or 'or', default: 'and')
=back
If any of the named arguments are specified, C<manifest()> will return
only items matching the specified criteria. This is an exact
case-sensitive match, but it can (especially in the case of mtype)
still return multiple elements.
=head3 Return values
Returns undef if there is no <manifest> element directly underneath
<package>, or if <manifest> contains no items.

=head1 MODIFIER METHODS
Unless otherwise specified, all modifier methods return undef if an
error was added to the error list, and true otherwise (even if a
warning was added to the warning list).
=head2 C<add_document($href,$id,$mediatype)>
Adds a document to the OPF manifest and spine, creating <manifest> and
<spine> if necessary. To add an item only to the OPF manifest, see
add_item().
=head3 Arguments
=over
=item C<$href>
The href to the document in question. Usually, this is just a
filename (or relative path and filename) of a file in the current
working directory. If you are planning to eventually generate a .epub
book, all hrefs MUST be in or below the current working directory.
The method returns undef if $href is not defined or empty.
=item C<$id>
The XML ID to use. If not specified, defaults to the href with
invalid characters removed.
This must be unique not only to the manifest list, but to every
element in the OPF file. If a duplicate ID exists, the method sets an
error and returns undef.
=item C<$mediatype> (optional)
The mime type of the document. If not specified, will attempt to
autodetect the mime type, and if that fails, will default to
'application/xhtml+xml'.

=item C<gi>
The generic identifier (tag) of the metadata element to alter or
create. If not specified, the method sets an error and returns undef.
=item C<parent>
The generic identifier (tag) of the parent to use for any newly
created element. If not specified, defaults to 'dc-metadata' if
'dc-metadata' exists underneath 'metadata', and 'metadata' otherwise.
A newly created element will be created under the first element found
with this gi. A modified element will be moved under the first
element found with this gi.
Newly created elements will use OPF 2.0 attribute names if the parent
is 'metadata' and OEB 1.2 attribute names otherwise.
=item C<text>
This specifies the element text to set. If not specified, the method
sets an error and returns undef.
=item C<id> (optional)
This specifies the ID to set on the element. If set and the ID is
already in use, a warning is logged and the ID is removed from the
other location and assigned to the element.
=item C<fileas> (optional)
This specifies the file-as attribute to set on the element.

=head2 C<gen_ncx($filename)>
Creates a NCX-format table of contents from the package
unique-identifier, the dc:title, dc:creator, and spine elements, and
then add the NCX entry to the manifest if it is not already
referenced.
Adds an error and fails if any of those cannot be found. The first
available dc:title is taken, but will prioritize dc:creator elements
with opf:role="aut" over those with no role attribute (see
twigelt_is_author() for details).
WARNING: This method REQUIRES that the e-book be in OPF 2.0 format to
function correctly. Call fix_opf20() before calling gen_ncx().
gen_ncx() will log an error and fail if $self{spec} is not set to
OPF20.

=head2 set_metadata(%args)
Sets the text and optionally the ID of the first specified element
type found (case-insensitive). Creates the element if one did not
exist (with the exact capitalization specified).
If a <dc-metadata> element exists underneath <metadata>, the language
element will be created underneath the <dc-metadata> and any standard
attributes will be created in OEB 1.2 format, otherwise the element is
created underneath <metadata> in OPF 2.0 format.
Returns 1 on success, returns undef if no gi or if no text was specified.
=cut
=head3 Arguments
=over
=item C<gi>
The generic identifier (tag) of the metadata element to alter or
create. If not specified, the method sets an error and returns undef.
=item C<parent>
The generic identifier (tag) of the parent to use for any newly
created element. If not specified, defaults to 'dc-metadata' if
'dc-metadata' exists underneath 'metadata', and 'metadata' otherwise.
A newly created element will be created under the first element found
with this gi. A modified element will be moved under the first
element found with this gi.
Newly created elements will use OPF 2.0 attribute names if the parent
is 'metadata' and OEB 1.2 attribute names otherwise.
=item C<text>
This specifies the element text to set. If not specified, the method
sets an error and returns undef.
=item C<id> (optional)
This specifies the ID to set on the element. If set and the ID is
already in use, a warning is logged and the ID is removed from the
other location and assigned to the element.

=head2 set_primary_author(%args)
Sets the text, id, file-as, and role attributes of the primary author
element (see L</primary_author()> for details on how this is found),
or if no primary author exists, creates a new element containing the
information.
This method calls L</fix_metastructure_basic()> to enforce the
presence of the <metadata> element. When creating a new element, the
method will use the OEB 1.2 element name and create the element
underneath <dc-metadata> if an existing <dc-metadata> element is found
underneath <metadata>. If no existing <dc-metadata> element is found,
the new element will be created with the OPF 2.0 element name directly
underneath <metadata>. Regardless, it is probably a good idea to call
L</fix_oeb12()> or L</fix_opf20()> after calling this method to ensure
a consistent scheme.
=head3 Arguments
Three optional named arguments can be passed:
=over
=item * C<text>
Specifies the author text to set. If omitted and a primary author
element exists, the text will be left as is; if omitted and a primary
author element cannot be found, an error message will be generated and
the method will return undef.
=item * C<fileas>
Specifies the 'file-as' attribute to set. If omitted and a primary
author element exists, any existing attribute will be left untouched;
if omitted and a primary author element cannot be found, the newly
created element will not have this attribute.
=item * C<id>
Specifies the 'id' attribute to set. If this is specified, and the id
is already in use, a warning will be added but the method will
continue, removing the id attribute from the element that previously
contained it.
If this is omitted and a primary author element exists, any existing
id will be left untouched; if omitted and a primary author element
cannot be found, the newly created element will not have an id set.
=back
If called with no arguments, the only effect this method has is to
enforce that either an 'opf:role' or 'role' attribute is set to 'aut'
on the primary author element.
=head3 Return values
Returns 1 if successful, returns undef and sets an error message if
the author argument is missing and no primary author element was
found.

=head2 C<find_links($filename)>
Searches through a file for href and src attributes, and returns a
list of unique links with any named anchors removed
(e.g. 'myfile.html#part7' returns as just 'myfile.html'). If no links
are found, or the file does not exist, returns undef.
Does not check to see if the links are local. Requires that links be
surrounded by double quotes, not single or left bare. Assumes that
any link will not be broken across multiple lines, so it will (for
example) fail to find:
<img src=
"myfile.jpg">

Takes a date string and attempts to convert it to the limited subset
of ISO8601 allowed by the OPF standard (YYYY, YYYY-MM, or YYYY-MM-DD).
In the special case of finding MM/DD/YYYY, it assumes that it was a
Mobipocket-mangled date, and not only converts it, but will strip the
day information if the day is '01', and both the month and day
information if both month and day are '01'. This is because
Mobipocket Creator enforces a complete MM/DD/YYYY even if the month
and day aren't known, and it is common practice to use 01 for an
unknown value.

########## END CODE ##########
=head1 BUGS AND LIMITATIONS
=over
=item * fix_links() could be improved to download remote URIs instead
of ignoring them.
=item * fix_links() needs to check the <reference> links under <guide>
=item * fix_links() needs to be redone with HTML::TreeBuilder or
Mojo::DOM to avoid the weakness with newlines between attribute names
and values
=item * Need to implement fix_tours() that should collect the related
elements and delete the parent if none are found. Empty <tours>
elements aren't allowed.
=item * fix_languages() needs to convert language names into IANA
language codes.
=item * set_language() should add a warning if the text isn't a valid
IANA language code.
=item * NCX generation only generates from the spine. It should be
possible to use a TOC html file for generation instead. In the long
term, it should be possible to generate one from the headers and
anchors in arbitrary HTML files.
=item * It might be better to use sysread / index / substr / syswrite in
&split_metadata to handle the split in 10k chunks, to avoid massive
memory usage on large files.
This may not be worth the effort, since the average size for most
books is less than 500k, and the largest books are rarely over 10M.
=item * The only generator is currently for .epub books. PDF,
PalmDoc, Mobipocket, Plucker, and iSiloX are eventually planned.
=item * Although I like keeping warnings associated with the ebook
object, it may be better to throw exceptions on errors and catch them
later. This probably won't be implemented until it bites someone who
complains, though.
=item * Unit tests are incomplete
