# htmlviewer-directediting installer
# Applies the HTML-in-iOS-App patches to a Nextcloud container.
# Usage: ./install.sh <container-name>
#   default container: nextcloud1-app-1
# Idempotent: safe to re-run after app updates.
#
# This version is CORE-CLEAN: the Nextcloud text app is NOT patched.
# The htmlviewer app registers its editor under the hard-coded app
# editor id "eurooffice" ("Öffnen mit Office" via long press). Plain
# tap on an HTML file still opens the source view (iOS default) —
# single-tap auto-open would require patching the text app, see
# README.md "Varianten".
