Feature: #58621 - FormatCaseViewHelper 

See forge#58621

Description 

Add a format case view helper to change casing of strings.

Possible modes are:

  • upper Transforms the input string to its uppercase representation
  • lower Transforms the input string to its lowercase representation
  • capital Transforms the input string to its first letter upper-cased
  • uncapital Transforms the input string to its first letter lower-cased
<f:format.case>Some Text with miXed case</f:format.case> renders "SOME TEXT WITH MIXED CASE"

<f:format.case mode="capital">someString</f:format.case> renders "SomeString"
Copied!

Impact 

The new ViewHelper can be used in all new projects. There is no interference with any part of existing code.
