TYPO3 Core

The feature config.sys_language_softMergeIfNotBlank sets the "mergeIfNotBlank" for a field in the frontend context through TypoScript. It can be useful to have the same for "exclude" localization mode so a field is always overlaid in the frontend output. This patch simply copies the code from "softMergeIfNotBlank" and does the same for "exclude".

See Additional below for documentation snipped for TSref.

TSref documentation, CONFIG object:
Property: sys_language_softMergeIfNotBlank
Data Type: string
Description: Setting additional "exclude" flags for l10n_mode in TCA for frontend rendering. Works exactly like sys_language_softMergeIfNotBlank (see that for details - same Syntax!).
Fields set in this property will override if the same field is set for "sys_language_softMergeIfNotBlank"
