+Revision history for Perl extension HTML-CalendarMonth.
+
+1.16 Fri Oct 21 16:23:48 EDT 2005
+ - Polished tests
+ - Fixed a Date::Calc testing procedure
+
+1.15 Fri Apr 1 12:43:09 EST 2005
+ - Split out tests
+ - Version roll hopefully ironed out some cpan tester
+ dependency issues
+
+1.14 Mon Mar 28 15:32:54 EST 2005
+ - forced dependency on HTML::ElementTable 1.13 or greater
+ - minor brush ups
+
+1.13 Mon Feb 28 16:02:31 EST 2005
+ - Streamlined accessor/mutator logic. Uses Class::Accessor now.
+ - Fixed a week of year bug introduced in the recent changes.
+ - General cleanup
+ - Added more tests (including one i8n test)
+
+1.12 Mon Feb 28 00:31:16 EST 2005
+ - Fixed auto-select bug that slipped through tests. :(
+ - Fixed tests.
+
+1.11 Sun Feb 27 23:58:04 EST 2005
+ - No reason to reinvent the wheel. Language support has now been
+ entirely replaced with full locale support as provided by
+ DateTime::Locale (does not require installation of entire
+ DateTime suite, if that's an issue)
+ - Calendrical calculations have now been fully abstracted out to
+ a back end interface. Calendars can be generated given the
+ presence of any one of the following and subject to the
+ circumstances of the request:
+
+ * native Time::Local (but limited to dates between 1970 and
+ 2038)
+ * Date::Calc
+ * DateTime
+ * Date::Manip
+ * unix 'cal' command
+
+1.10 Sat Feb 26 00:47:37 EST 2005
+ - Added more robust language support. Currently supports en,
+ de, and fr.
+
+1.09 Tue Mar 26 05:21:59 CST 2002
+ - Fixed obscure bug that caused March 31 2002
+ to be dropped; related to a localtime/gmtime
+ issue with DST effects.
+ - Added tests for calendars over 1-year span
+ plus special cases such as the aforementioned
+ March 31 2002 instance.
+
+1.08 Mon Jan 8 19:15:16 CST 2001
+ - Added Date::Manip fallback from Date::Calc,
+ so a C compiler is not strictly necessary
+ for folks wanting week-of-year numbering
+ or exotic dates.
+
+1.07 Wed Nov 8 01:42:40 CST 2000
+ - Day-of-week bug REALLY fixed. Should now work
+ properly with all perumutations of calendar
+ pecularities and concepts of what the first
+ day of the week should be.
+
+1.06 Wed Oct 4 13:37:31 CDT 2000
+ - Day-of-week bug fixed for cases where Sunday is
+ the first day of the month (such as Oct, 2000),
+ or last day of the month (such as Dec, 2000),
+ over various configurations of what is considered
+ the first day of the week.
+
+1.04 Sun Sep 17 12:13:40 CDT 2000
+ - Documentation tweaks and corrections.
+
+1.03 Wed Apr 26 12:06:23 CDT 2000
+ - Added HTML::ElementTable dependency check in Makefile.PL
+ - Various bug fixes, under less common circumstances.
+ - Code syntax tweaks.
+
+1.02 Tue Jan 25 20:05:05 CST 2000
+ - Cleaned up -w noise
+ - Added mailing list information
+
+1.01 Thu Sep 16 15:33:41 CDT 1999
+ - Distribution patch
+ - Purged erroneus Date::Manip references
+
+1.00 Tue Jul 27 21:55:43 CDT 1999
+ - abstracted item/coord translations to cell refs
+ rather than redundant coord lookups
+ - initial release
+
+0.09 Thu Jul 8 19:02:39 CDT 1999
+ - added week counts and arbitrary 1st DOW
+
+0.08 Fri Jul 10 19:58:28 1998
+ - first public version

+HTML-CalendarMonth
+-------------------
+
+HTML::CalendarMonth is a module that simplifies the rendering of a
+calendar month in HTML. It is NOT a scheduling system.
+
+Calendars are represented as HTML::Element based structures, derived
+from the HTML::ElementTable class.
+
+The module includes support for 'week of the year' numbering, arbitrary
+1st day of the week definitions, and aliasing so that you can express
+any element in any language HTML can handle.
+
+If you wish to use 'week of the year' numbering, or want to explore
+dates beyond the capability of the internal perl time functions, then
+you will need Date::Calc or Date::Manip.
+
+INSTALLATION
+
+You install HTML-Calendar, as you would install any perl module library,
+by running these commands:
+
+ perl Makefile.PL
+ make
+ make test
+ make install
+
+DOCUMENTATION
+
+See HTML/CalendarMonth.pm for the code. See Changes for recent changes.
+POD style documentation is included in the module. This is normally
+converted to a manual page and installed as part of the "make install"
+process. You should also be able to use the 'perldoc' utility to extract
+and read documentation from the module directly.
+
+Some examples can be found here:
+
+ http://www.mojotoad.com/sisk/projects/HTML-CalendarMonth/examples.html
+
+SUPPORT
+
+There is a mailing list for HTML::Calendar. To subscribe or view past
+messages, please visit the following URL:

+=head1 DESCRIPTION
+
+HTML::CalendarMonth is a subclass of HTML::ElementTable. See
+L<HTML::ElementTable(3)> for how that class works, for it affects this
+module on many levels. Like HTML::ElementTable, HTML::CalendarMonth
+behaves as if it were an HTML::ElementSuper, which is a regular
+HTML::Element with methods added to easily manipulate the appearance of
+the HTML table containing the calendar.
+
+The primary interaction with HTML::CalendarMonth is through I<items>. An
+I<item> is merely a symbol that represents the content of the cell of
+interest within the calendar. For instance, the element representing the
+14th day of the month would be returned by C<$c-E<gt>item(14)>.
+Similarly, the element representing the header for Monday would be
+returned by C<$c-E<gt>item('Mo')>. If the year happened to by 1984, then
+C<$c-E<gt>item(1984)> would return the cell representing the year. Since
+years and particular months change frequently, it is probably more
+useful to take advantage of the C<month()> and C<year()> methods, which
+return the respective item symbol for the current calendar. In the prior
+example, using 1984, the following is equivalent: C<$c-E<gt>item($c-
+E<gt>year())>.
+
+Multiple cells of the calendar can be manipulated as if they were a
+single element. For instance, C<$c-E<gt>item(15)-E<gt>attr(bgcolor
+=E<gt> 'cyan')> would alter the background color of the cell
+representing the 15th. By the same token, C<$c-E<gt>item(15, 16, 17,
+23)-E<gt>attr(bgcolor =E<gt> 'cyan')> would do the same thing for all
+cells containing the item symbols passed to the C<item()> method.
+
+The calendar structure is still nothing more than a table structure; the
+same table structure provided by the HTML::ElementTable class. In
+addition to the I<item> based access methods above, calendar cells can
+still be accessed using row and column grid coordinates using the
+C<cell()> method provided by the table class. All coordinate-based
+methods in the table class are accessible to the calendar class.
+
+The module includes support for week-of-the-year numbering, arbitrary
+1st day of the week definitions, and aliasing so that you can express
+any element in any language HTML can handle.
+
+Dates that are beyond the range of the built-in time functions of perl
+are handled either by the 'cal' command, Date::Calc, or Date::Manip. The
+presence of any one of these utilities and modules will suffice for
+these far flung date calculations. If you want to use week-of-year
+numbering, then either one of the date modules is required.
+
+Full locale support is offered via DateTime::Locale. For a full list of
+supported locale id's, look at HTML::CalendarMonth::Locale->locales() or
+DateTime::Locale->ids().
+
+=head1 METHODS
+
+All arguments appearing in [brackets] are optional, and do not represent
+anonymous array references.
+
+=over
+
+B<Constructor>
+
+=item new()
+
+With no arguments, the constructor will return a calendar object
+representing the current month with a default appearance. The initial
+configuration of the calendar is controlled by special attributes. Non-
+calendar related attributes are passed along to HTML::ElementTable. Any
+non-table related attributes left after that are passed to HTML::Element
+while constructing the E<lt>tableE<gt> tag. See L<HTML::ElementTable> if
+you are interested in attributes that can be passed along to that class.
+
+Special Attributes for HTML::CalendarMonth:
+
+=over
+
+=item month
+
+1-12, or Jan-Dec. Defaults to current month.
+
+=item year
+
+Four digit representation. Defaults to current year.
+
+=item head_m
+
+Specifies whether to display the month header. Default 1.
+
+=item head_y
+
+Specifies whether to display the year header. Default 1.
+
+=item head_dow
+
+Specifies whether to display days of the week header. Default 1.
+
+=item locale
+
+Specifies a locale in which to render the calendar. Default is 'en_US'.
+See L<HTML::CalendarMonth::Locale> for more information. If for some
+reason you prefer to use different labels than those provided by
+C<locale>, see the C<alias> attribute below.
+
+=item full_days
+
+Specifies whether or not to use full day names or their abbreviated
+names. Default is 0, use abbreviated names.
+
+=item full_months
+
+Specifies whether or not to use full month names or their abbriviated
+names. Default is 1, use full names.
+
+=item alias
+
+Takes a hash reference mapping labels provided by C<locale> to any
+custom label you prefer. Lookups, such as C<day('Sun')>, will still use
+the locale string, but when the calendar is rendered the aliased value
+will appear.
+
+=item head_week
+
+Specifies whether to display the week-of-year numbering. Default 0.
+
+=item week_begin
+
+Specify first day of the week, which can be 1..7, starting with Sunday.
+Defaults to 1, or Sunday. In order to specify Monday, set this to 2,
+and so on.
+
+=item row_offset
+
+Specifies the offset of the first calendar row within the table
+containing the calendar. This is 0 by default, making the first row of
+the table the same as the first row of the calendar.
+
+=item col_offset
+
+Specifies the offset of the first calendar column within the table
+containing the calendar. This is 0 by default, making the first column
+of the table the same as the first row of the calendar.
+
+=item historic
+
+This option is ignored for dates that do not exceed the range of the built-
+in perl time functions. For dates that B<do> exceed these ranges, this
+option specifies the default calculation method. When set, if the 'cal'
+utility is available on your system, that will be used rather than the
+Date::Calc or Date::Manip modules. This can be an issue since the date
+modules blindly extrapolate the Gregorian calendar, whereas 'cal' takes
+some of these quirks into account. If 'cal' is not available on your
+system, this attribute is meaningless. Defaults to 1.

+
+B<Item Query Methods>
+
+The following methods return lists of item symbols that are related in
+some way to the provided list of items. The returned symbols may then
+be used as arguments to the glob methods detailed further below. When
+these methods deal with 'rows' and 'columns', they are only concerned
+with the cells in the calendar -- not the cells that might be present
+in the surrounding table if you have extended it. If you have not set
+row or column offsets, or extended the span of the containing table,
+then these rows and columns are functionally equivalent to the table
+rows and columns.
+
+=over
+
+=item row_items(item1, [item2, ...])
+
+Returns all item symbols in rows shared by the provided item symbols.
+
+=item col_items(item1, [item2, ...])
+
+Returns all item symbols in columns shared by the provided item symbols.
+
+=item daycol_items(col_item1, [col_item2, ...])
+
+Same as col_items(), but the returned item symbols are limited to those
+that are not header items (month, year, day-of-week).
+
+=item row_of(item1, [item2, ...])
+
+Returns the row numbers of rows containing the provided item symbols.
+
+=item col_of(item1, [item2, ...])
+
+Returns the column numbers of columns containing the provided
+item symbols.
+
+=item lastday()
+
+Returns the number of the last day of the month.
+
+=item dow1st()
+
+Returns the column number for the first day of the month.
+
+=item days()
+
+Returns a list of all days of the month.
+
+=item dayheaders()
+
+Returns a list of all day headers (Su..Sa)
+
+=item headers()
+
+Returns a list of all headers (month, year, dayheaders)
+
+=item items()
+
+Returns a list of all item symbols in the calendar.
+
+=item first_col()
+
+Returns the number of the first column of the calendar. This could be
+different from that of the surrounding table if the table was extended,
+but otherwise should be identical.
+
+=item last_col()
+
+Returns the number of the last column of the calendar. This could be
+different from that of the surrounding table if the table was extended,
+but should otherwise be identical.
+
+=item first_row()
+
+Returns the number of the first row of the calendar. This could be
+different from that of the surrounding table if offsets were made.
+
+=item first_week_row()
+
+Returns the number of the first row of the calendar containing day items
+(ie, the first week). This could vary depending on table offsets and
+header modes.
+
+=item last_row()
+
+Returns the number of the last row of the calendar. This could be
+different from that of the surrounding table if the table was extended,
+but should otherwise be identical.
+
+=back
+
+B<Glob Methods>
+
+Glob methods return references that are functionally equivalent to an
+individual calendar cell. Mostly, they provide item based analogues to
+the glob methods provided in HTML::ElementTable. In methods dealing with
+rows, columns, and boxes, the globs include empty calendar cells (which
+would otherwise need to be accessed through native HTML::ElementTable
+methods). The row and column numbers returned by the item methods above
+are compatible with the grid based methods in HTML::ElementTable.
+
+For details on how these globs work, check out L<HTML::ElementTable> and
+L<HTML::ElementGlob>.
+
+=over
+
+=item item(item1, [item2, ...])
+
+Returns all cells containing the provided item symbols.
+
+=item item_row(item1, [item2, ...])
+
+Returns all cells in all rows occupied by the provided item symbols.
+
+=item item_col(item1, [item2, ...])
+
+Returns all cells in all columns occupied by the provided item symbols.
+
+=item item_daycol(item1, [item2, ...])
+
+Same as item_col(), except limits the cells to non header cells.
+
+=item item_box(item1a, item1b, [item2a, item2b, ...])
+
+Returns all cells in the boxes defined by the item pairs provided.
+
+=item allheaders()
+
+Returns all header cells.
+
+=item alldays()
+
+Returns all non header cells, including empty cells.
+
+=item all()
+
+Returns all cells in the calendar, including empty cells.
+
+=back
+
+B<Transformation Methods>
+
+The following methods provide ways of translating between various item
+symbols, coordinates, and other representations.
+
+=over
+
+=item coords_of(item)
+
+Returns the row and column of the provided item symbol, for use with the
+grid based methods in HTML::ElementTable.
+
+=item item_at(row,column)
+
+Returns the item symbol of the item at the provided coordinates, for use
+with the item based methods of HTML::CalendarMonth.
+
+=item monthname(monthnum)
+
+Returns the name (item symbol) of the month number provided, where
+I<monthnum> can be 1..12.
+
+=item monthnum(monthname)
+
+Returns the number (1..12) of the month name provided. Only a minimal
+case-insensitive match on the month name is necessary; the proper item
+symbol for the month will be determined from this match.
+
+=item dayname(daynum)
+
+Returns the name (item symbol) of the day of week header for a number of
+a day of the week, where I<daynum> is 1..7.
+
+=item daynum(dayname)
+
+Returns the number of the day of the week given the symbolic name for
+that day (Su..Sa).
+
+=item daytime(day)
+
+Returns the number in seconds since the epoch for a given day. The day
+must be present in the current calendar.
+
+=back
+
+=head1 Notes On Dates And Spatial Relationships
+
+One of the nice things about having a calendar represented as a table
+accessible with grid coordinates is that some of the trickier date
+calculations become trivial. You can use packages such as I<Date::Manip>
+or I<Date::Calc> for these sort of things, but the algorithms are often
+derived from a common human activity: looking at a calendar on a wall.
+Say, for instance, that you are interested in "the third Friday of every
+month". If you are using a calendar with Sunday as the first day of the
+week, then Fridays will always be in column 5, starting from 0.
+Likewise, due to the fact that supressed headers are merely I<masked> in
+the actual table, the first row with dates in a calendar structure will
+B<always> be 2, even if the month, year, or day headers are disabled.
+The third friday of every month therefore becomes C<$c-E<gt>cell(2,5)>,
+regardless of the particular month. Likewise, the "nth dayname/week of
+the month" can always be mapped to table coordinates.
+
+The particulars of this grid mapping are affected if you have redefined
+what the first day of the week is, or if you have tweaked the table
+beyond the bounds of the calendar itself. There are methods that can
+help under these circumstances, though. For instance, in our example
+where we are interested in the 3rd Friday of the month, the row number
+is accessed with C<$c-E<gt>first_week_row + 2>, whereas the column
+number could be derived with C<$c-E<gt>last_col - 1>.

+=head1 NAME
+
+HTML::CalendarMonth::DateTool - Base class for determining which date package to use for calendrical calculations.
+
+=head1 SYNOPSIS
+
+ my $date_tool = HTML::CalendarMonth::DateTool->new(
+ year => $YYYY_year,
+ month => $one_thru_12_month,
+ weeknum => $weeknum_mode,
+ historic => $historic_mode,
+ datetool => $specific_datetool_if_desired,
+ );
+
+=head1 DESCRIPTION
+
+This module attempts to utilize the best date calculation package
+available on the current system. For most contemporary dates this
+usually ends up being the internal Time::Local package of perl. For more
+exotic dates, or when week number of the years are desired, other
+methods are attempted including DateTime, Date::Calc, Date::Manip, and
+the unix 'cal' command. Each of these has a specific subclass of this
+module offering the same utility methods needed by HTML::CalendarMonth.
+
+=head1 METHODS
+
+=over
+
+=item new()
+
+Constructor. Takes the following parameters:
+
+=over
+
+=item year
+
+Year of calendar in question (required). If you are rendering exotic
+dates (i.e. dates outside of 1970 to 2038) then something besides
+Time::Local will be used for calendrical calculations.
+
+=item month
+
+Month of calendar in question (required). 1 through 12.
+
+=item weeknum
+
+Optional. When specified, will limit class excursions to those that are
+currently set up for week of year calculations.
+
+=item historic
+
+Optional. If the 'cal' command is available, use it rather than other available
+date modules since the 'cal' command accurately handles some specific
+historical artifacts such as the transition from Julian to Gregorian.
+
+=item datetool
+
+Optional. Mostly for debugging, this option can be used to indicate a
+specific HTML::CalendarMonth::DateTool subclass for instantiation. The
+value can be either the actual utility class, e.g., Date::Calc, or the
+name of the CalendarMonth handler leaf class, e.g. DateCalc. For the
+'cal' command, use 'cal'.
+
+=back
+
+=back
+
+There are number of methods automatically available:
+
+=over
+
+=item month()
+
+=item year()
+
+=item weeknum()
+
+=item historical()
+
+=item datetool()
+
+Accessors for the parameters provided to C<new()> above.
+
+=item dow1st()
+
+Returns the day of week number for the 1st of the C<year> and C<month>
+specified during the call to C<new()>. Relies on the presence of
+C<dow1st_and_lastday()>.
+
+=item lastday()
+
+Returns the last day of the month for the C<year> and C<month> specified
+during the call to C<new()>. Relies on the presence of
+C<dow1st_and_lastday()>.
+
+=back
+
+=head1 Overridden methods
+
+Subclasses of this module must provide at least the C<day_epoch()> and
+C<dow1st_and_lastday()> methods.
+
+=over
+
+=item dow1st_and_lastday()
+
+Required. Provides a list containing the day of the week of the first day of the
+month along with the last day of the month.
+
+=item day_epoch()
+
+Optional unless interested in epoch values for wacky dates. For a given
+day, and optionally C<month> and C<year> if they are different from
+those specified in C<new()>, provide the unix epoch in seconds for that
+day at midnight.
+
+=back
+
+If the subclass is expected to provide week of year numbers, three more
+methods are necessary:
+
+=over
+
+=item dow()
+
+For a given day, and optionally C<month> and C<year> if they are
+different from those specified in C<new()>, provide the day of week
+number. (1=Sunday, 6=Saturday).
+
+=item add_days($days, $delta, $day, [$month], [$year])
+
+For a given day, and optionally C<month> and C<year> if they are
+different from those specified in C<new()>, provide a list of year,
+month, and day once C<delta> days have been added.
+
+=item week_of_year($day, [$month], [$year])
+
+For a given day, and optionally C<month> and C<year> if they are
+different from those specified in C<new()>, provide a list with the week
+number of the year along with the year. (some days of a particular year
+can end up belonging to the prior or following years).

+=head1 NAME
+
+HTML::CalendarMonth::Locale - Front end class for DateTime::Locale
+
+=head1 SYNOPSIS
+
+ use HTML::CalendarMonth::Locale;
+
+ my $loc = HTML::CalendarMonth::Locale->new( id => 'en_US' );
+
+ # list of days of the week for locale
+ my @days = $loc->days;
+
+ # list of months of the year for locale
+ my @months = $loc->months;
+
+ # the name of the current locale, as supplied the id parameter to
+ # new()
+ my $locale_name = $loc->id;
+
+ # the actual DateTime::Locale object
+ my $loc = $loc->loc;
+

+
+=head1 DESCRIPTION
+
+HTML::CalendarMonth utilizes the powerful locale capabilities of
+DateTime::Locale for rendering its calendars. The default locale is
+'en_US' but many others are available. To see this list, invoke the
+class method HTML::CalendarMonth::Locale->locales() which in turn
+invokes DateTime::Locale::ids().
+
+This module is mostly intended for internal usage within
+HTML::CalendarMonth, but some of its functionality may be of use for
+developers:
+
+=head1 METHODS
+
+=item new()
+
+Constructor. Takes the following parameters:
+
+=over
+
+=item id
+
+Locale id, e.g. 'en_US'.
+
+=item full_days
+
+Specifies whether full day names or their abbreviations are desired.
+Default 0, use abbreviated days.
+
+=item full_months
+
+Specifies whether full month names or their abbreviations are desired.
+Default 1, use full months.
+
+=back
+
+=item id()
+
+Returns the locale id used during object construction.
+
+=item locale()
+
+Accessor method for the DateTime::Locale class, which in turn offers
+several class methods of specific interest. See L<DateTime::Locale>.
+
+=item loc()
+
+Accessor method for the DateTime::Locale instance as specified by C<id>.
+See L<DateTime::Locale>.
+
+=item locales()
+
+Lists all available locale ids. Equivalent to locale()->ids(), or
+DateTime::Locale->ids().
+
+=item days()
+
+Returns a list of days of the week, Sunday first. These are the actual
+days used for rendering the calendars, so depending on which attributes
+were provided to C<new()>, this list will either be abbreviations or
+full names. The default uses abbreviated day names. Returns a list in
+list context or an array ref in scalar context.
+
+=item months()
+
+Returns a list of months of the year, beginning with January. Depending
+on which attributes were provided to C<new()>, this list will either be
+full names or abbreviations. The default uses full names. Returns a list
+in list context or an array ref in scalar context.
+
+=item minmatch()
+
+Provides a hash reference containing minimal match strings for each
+month of the year, e.g., 'N' for November, 'Ja' for January, 'Jul' for
+July, 'Jun' for June, etc.
+
+=item daynums()
+
+Provides a hash reference containing day of week numbers for each day
+name.
+
+=item daynum($day)
+
+Provides the day of week number for a particular day name.
+
+=item monthnums()
+
+Provides a hash reference containing month of year numbers for each
+month name.
+
+=item monthnum($month)
+
+Provides the month of year number for a particular month name.
+
+=item minmatch_hash(@list)
+
+This is the method used to generate the minimal match hash referenced
+above. Given an arbitrary list, a hash reference will be returned with
+minimal match strings as keys and full names as values.
