Feature: #86422 - TypoScript getText property site

See Issue #86422

Description

Site configuration can now be accessed via the getText property in TypoScript.

Example:

page.10 = TEXT
page.10.data = site:base
page.10.wrap = This is your base URL: |

Where site is the keyword for accessing an aspect, and the following parts are the configuration key(s) to access.

data = site:customConfigKey.nested.value

Impact

Accessing site configuration is now possible in TypoScript, which enables to store site specific configuration options in one central place and allows usage of that configuration from different contexts. While this sounds similar to using TypoScript, with using site configuration this may also be used from backend or CLI context as long as the rootPageId of the site is known. To avoid duplicating configuration options, TypoScript can now access these properties, too.
