---++ Summary of Contents
This module packages the [[http://dynarch.com/mishoo/calendar.epl][Mishoo JSCalendar]] Javascript in a form suitable for use with Foswiki.

---++ Detailed Documentation

Read [[%ATTACHURL%/doc/html/reference.html][the Mishoo documentation]] or
[[%ATTACHURL%][visit the demo page]] for detailed information on using the
calendar widget.

This package also includes a small Perl module to make using the calendar
easier from Foswiki plugins. This module includes the functions:


---+++ Foswiki::Contrib::JSCalendarContrib::renderDateForEdit($name, $value, $format [, \%cssClass]) -> $html

This is the simplest way to use calendars from a plugin.
   * =$name= is the name of the CGI parameter for the calendar
     (it should be unique),
   * =$value= is the current value of the parameter (may be undef)
   * =$format= is the format to use (optional; the default is set
     in =configure=). The HTML returned will display a date field
     and a drop-down calendar.
   * =\%options= is an optional hash containing base options for
     the textfield.
Example:
<verbatim>
use Foswiki::Contrib::JSCalendarContrib ();
...
my $fromDate = Foswiki::Contrib::JSCalendarContrib::renderDateForEdit(
   'from', '1 April 1999');
my $toDate = Foswiki::Contrib::JSCalendarContrib::renderDateForEdit(
   'to', undef, '%Y');
</verbatim>


---+++ Foswiki::Contrib::JSCalendarContrib::addHEAD($setup)

This function will automatically add the headers for the calendar to the page
being rendered. It's intended for use when you want more control over the
formatting of your calendars than =renderDateForEdit= affords. =$setup= is
the name of
the calendar setup module; it can either be omitted, in which case the method
described in the Mishoo documentation can be used to create calendars, or it
can be ='foswiki'=, in which case a Javascript helper function called
'showCalendar' is added that simplifies using calendars to set a value in a
text field. For example, say we wanted to display the date with the calendar
icon _before_ the text field, using the format =%Y %b %e=
<verbatim>
# Add styles and javascript for the calendar
use Foswiki::Contrib::JSCalendarContrib ();
...

sub commonTagsHandler {
  ....
  # Enable 'showCalendar'
  Foswiki::Contrib::JSCalendarContrib::addHEAD( 'foswiki' );

  my $cal = CGI::image_button(
      -name => 'img_datefield',
      -onclick =>
       "return showCalendar('id_datefield','%Y %b %e')",
      -src=> Foswiki::Func::getPubUrlPath() . '/' .
             $Foswiki::cfg{SystemWebName} .
             '/JSCalendarContrib/img.gif',
      -alt => 'Calendar',
      -align => 'middle' )
    . CGI::textfield(
      { name => 'date', id => "id_datefield" });
  ....
}
</verbatim>
The first parameter to =showCalendar= is the id of the textfield, and the second parameter is the date format. Default format is '%e %B %Y'.

#FormatSpecifiers
All available date specifiers:
<verbatim>
%a - abbreviated weekday name 
%A - full weekday name 
%b - abbreviated month name 
%B - full month name 
%C - century number 
%d - the day of the month ( 00 .. 31 ) 
%e - the day of the month ( 0 .. 31 ) 
%H - hour ( 00 .. 23 ) 
%I - hour ( 01 .. 12 ) 
%j - day of the year ( 000 .. 366 ) 
%k - hour ( 0 .. 23 ) 
%l - hour ( 1 .. 12 ) 
%m - month ( 01 .. 12 ) 
%M - minute ( 00 .. 59 ) 
%n - a newline character 
%p - "PM" or "AM"
%P - "pm" or "am"
%S - second ( 00 .. 59 ) 
%s - number of seconds since Epoch (since Jan 01 1970 00:00:00 UTC) 
%t - a tab character 
%U, %W, %V - the week number
   The week 01 is the week that has the Thursday in the current year,
   which is equivalent to the week that contains the fourth day of January. 
   Weeks start on Monday.
%u - the day of the week ( 1 .. 7, 1 = MON ) 
%w - the day of the week ( 0 .. 6, 0 = SUN ) 
%y - year without the century ( 00 .. 99 ) 
%Y - year including the century ( ex. 1979 ) 
%% - a literal % character 
</verbatim>

=addHEAD= can be called from =commonTagsHandler= for adding the header to all pages, or from =beforeEditHandler= just for edit pages etc.

An alternative to =commonTagsHandler= is =postRenderingHandler= which is more efficient since it is called less often.



---+++ Using the Calendar for picking dates only or picking times and dates

The calendar is able to display a time-picker, in addition to the default date-picker, depending on the optional date format passed.

   * the calendar displays the built-in time picker when the passed format descriptions includes hours, minutes or am or pm specifiers (i.e.: =%H, %I, %k, %l, %M, %p, %P=),
   * otherwise the calendar is displayed normally with only dates if anything else or no format description is passed.

---+++ Using the Calendar in user forms
You can also use the calendar directly in your own hand-built forms, without
having to write any code. Just add this inline in the topic text:
<verbatim class="tml">
%INCLUDE{"%SYSTEMWEB%/JSCalendarContribInline"}%
</verbatim>
Then, to display a calendar icon next to a text input field:
<verbatim class="tml">
<input type="text" id="cal_val_here" />
<input type="image" src="%PUBURL%/%SYSTEMWEB%/JSCalendarContrib/img.gif"\
       onclick="javascript: return showCalendar('cal_val_here','%e %B %Y')" />
</verbatim>
If the contrib is installed, you will see such a field here:
%INCLUDE{"%SYSTEMWEB%/JSCalendarContribInline"}%
<input type="text" id="cal_val_here" />
<input type="image" src="%PUBURL%/%SYSTEMWEB%/JSCalendarContrib/img.gif"\
       onclick="javascript: return showCalendar('cal_val_here','%e %B %Y')" />

<!--
   * Set SHORTDESCRIPTION = [[http://dynarch.com/mishoo/calendar.epl][Mishoo JSCalendar]], packaged for use by plugins, skins and add-ons
-->

---+++ Installation Instructions
You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

If you have any problems, or if the extension isn't available in =configure=, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.


---+++ Customizing the appearance of the calendar

   * An administrator can customize the default appearance of the calendar using the =configure= interface to set the style, language and time format options.
   * Users can customize the appearance of the calendar, overriding the administrator's choices, either system-wide (at %LOCALSITEPREFS%), by web (at the !WebPreferences topic), and even or per-topic basis. To do that they need to define the following settings: 
      | *Setting* | *Default value* |
      | JSCALENDARCONTRIB_FORMAT | %e %b %Y |
      | JSCALENDARCONTRIB_STYLE | blue |
      | JSCALENDARCONTRIB_LANG | en |
