[OpenAjaxIDE] date formatting

Besides YUI, what formats do we need to support?  I'd still like to hear
more examples, not just to justify this but to help isolate the range of
formats needed.  Specifically, which other widgets are known not to support
ISO dates?  Does it follow that Unix epoch timestamps need to be supported

Also, Steve, do your format chars follow any existing library?  The common
ones I know of are PHP, Unix, and Java.  iirc, PHP and Unix are similar but
not identical.

Here’s currently what my 40 lines supports:

formatstr = [string] formatting string with embedded instructions
            on how to format the current date and/or time. If no
            value is specified returns the date with the default
            date formatting, "mm-dd-yy".

            The format string can consist of any combination of
            literal characters and special characters, which

            mm   = current month as "1"
            MM   = current month as "01"
            MMM  = current month as "Jan"
            MMMM = current month as "January"

            dd   = current day as "1"
            DD   = current day as "01"
            DDD  = current day as "1st"
            DDDD = current day as "Saturday"

            YY   = current day as "01"
            YYYY = current day as "2001"

            hh   = current hour as "05" (12-hour clock)
            HH   = current hour as "17" (24-hour clock)

            MN   = current minutes as "01"

            SS   = current seconds as "01"

            ap   = current am/pm as "am"
            AP   = current am/pm as "AM"

I think a lightweight solution that supports a very small set of legacy
formats would be all we need.  Sounds like Steve’s 40+ lines of DateFormat
code could handle this.

I like a simple approach of adding an additional formatString=”” attribute
or maybe call it formatPattern that enables you to format in the value that
is replaced using the @@variableName@@ notation in either the <javascript>
or <content> sections.  Here is an example.

<property datatype=”date” format=”date” formatString=”YYYY-MM-DD” />

     YYYY = four-digit year
     MM   = two-digit month (01=January, etc.)
     DD   = two-digit day of month (01 through 31)
     hh   = two digits of hour (00 through 23) (am/pm NOT allowed)
     mm   = two digits of minute (00 through 59)
     ss   = two digits of second (00 through 59)

The formats from YUI Calendar takes Javascript Date Object or a string
formatted as “mm/yyyy” and “mm/dd/yyyy”.  The selected property can only be
specified with a string not a Javascript date object and it does not
support ISO 8601 format.  See this link


Here is an example of how we could support YUI Calendar date strings using

var cal1 = new YAHOO.widget.Calendar("cal1",
                                       { pagedate:"5/2007",
                                         selected:"5/5/2007-5/27/2007" });

This would look like the following in the oam.xml file:

var cal1 = new YAHOO.widget.Calendar("cal1",
                                       { pagedate:"@@pageDate@@",

selected:"@@selectDateStart@@-@@selectDateEnd@@" });

      <property name=”pageDate” datatype=”date” format=”date”
      formatString=”MM/YYYY” />
      <property name=” selectDateStart” datatype=”date” format=”date”
      formatString=”MM/DD/YYYY” />
      <property name=” selectDateEnd” datatype=”date” format=”date”
      formatString=”MM/DD/YYYY” />

Not sure if we should support dropping out leading 0’s, do we need to
support this?  We could do with just M or D. But the YUI calendar works
specifying dates with or without leading 0’s. So this may be unnecessary.

Here is the link for jQuery Date formats.  They support multiple formats
including iso 8601.  So with  could support it as follows:


Here are some examples from jQuery

$('.selector').datepicker({ appendText: '(YYYY-MM-DD)' });

Here is what this would like in the oam.xml file:

      $('.selector').datepicker({ appendText: '(@@appendText@@)' });

      <property name=”appendText” datatype=”date” format=”date”
      formatString=” YYYY-MM-DD” />

Just wanted to remind you that the 40+/- lines of code from my dateFormat()
function would handle your example as follows:

dateFormat( “MM/YYYY” )
dateFormat( “MM/DD/YYYY” )
dateFormat( “MM/DD” )
the above renders the current date in the desired formats. Alternatively,
you could specify have specified a specific date as the first parameter.

Please note, that dateFormat( ) has very little internationalization other
than inherited from JS, but again if you are interested I would be happy to
dinate the code base.

I want to make sure I understand the use case for date formatting.

One of the target scenarios mentioned during yesterday's phone call was the
YUI calendar widget:

* http://developer.yahoo.com/yui/calendar/

which takes a few parameters (pagedate, selected, mindate, maxdate) which
are expected to look like:


Am I understanding the YUI documentation correctly?

I believe the target workflow is that an IDE (e.g., Dreamweaver) recognizes
that a particular property is a date (e.g., due to format="date") and posts
a date picker widget, and after the user picks a date, then the IDE needs
to format the date value into a format that is compatible with what the
widget's constructor expects. Correct?

Kin or Scott: do you have an OAM file for the YUI date picker widget? I
would like to see how the OAM file is set up, particularly how the data
parameters are set up, and what aspects of the OAM file are a mismatch with

Below I have copied an OAM file that I found on the Dreamweaver extensions
site for a YUI tooltip widget. If the OAM file for the YUI calendar widget
uses similar approaches (e.g., <javascript location="afterContent">), then
it seems to me that the transformation of the date value into MM/DD/YYYY
format would be easy to do via JavaScript that is included with the logic
in the <javascript> element.



<?xml version="1.0" encoding="utf-8"?>

<widget xmlns:dw="http://ns.adobe.com/dreamweaver"

<javascript location="afterContent">

var cn = document.body.className.toString();
if (cn.indexOf('yui-skin-sam') == -1) {
document.body.className += " yui-skin-sam";

var @@yuitooltip@@ = new YAHOO.widget.Tooltip("@@yuitooltip@@",
text:"You are hovering over the Lorem Ipsum paragraph."

<p>The Tooltip Control is analogous to popup tooltips within common
operating systems. The standard tooltip interaction pattern involves a
small overlay that is displayed when the mouse hovers over a context
element for a specified amount of time. Tooltip is designed to be simple to
implement with easily-accessed configuration options and visual styling
handled entirely via CSS.</p>
<p>The Yahoo! User Interface (YUI) Library is a set of components, written

techniques such as DOM scripting, DHTML and AJAX. The YUI Library also
includes several core CSS resources. All components in the YUI Library are
available under the BSD license and are free for all uses. More information
