Bug 97633 – [Forms] Adding localization texts for multiple fields date/time input UI

• Component: Forms
• Status: RESOLVED FIXED

To implement multiple fields date/time input UI, we would like to have:
  1. month format in LDML, e.g. "MM/yyyy"
  2. week format in LDML, e.g. "W/yyyy"
  3. date format indicates letters, e.g. "ymd" to display "dd-mm-yyyy"

Why don't you rename it before this patch?

Because we have no call sites of these functions yet, none except you can understand what the functions should return.
Please explain what they are and why they are needed concretely.

threeletters -> three letters?
Is "年" one letter? Should we count a character of which code point is greater than U+FFFF as one letter? How about Unicode composition?

still unclear.  In what situation a user will see this text? What text is expected?

Each letter should have same width to "-" in monospace font-family. This function may return empty string if there are no such letters in locale or order of day, month and year is well-known in locale.

This doesn't resolve my previous question.  is a sequence of 'A' and U+0300 (COMBINING GRAVE ACCENT) one letter?  Why don't you support at most two letters for one field though a day/month/year field has at least two digits?

BTW, these explanation should be in LocalizedStrings.h and WebCore/ChangeLog, not WebKit/chromium/ChangeLog.

This string will be displayed bubble when the input element is focused and dateFormatHelpLetters() returns empty string. This function may return empty string if order of day, month, and year is well-known in locale.

We already have WebCore::localizedDateFormatText().  Also, a date format depends on a local machine setting, and we need some code to build this text.  Such text is not suitable for LocalizedStrings.
