customizer.sh

#!/bin/bash
#
# Kotlin Multiplatform Project Customizer
#
# Usage:
#   bash customizer.sh <package_id> <project_name> [app_display_name] [ios_team_id] [--keep-demo]
#   bash customizer.sh --clean [--apply]            # standalone demo removal (no identity change)
#
# Example:
#   bash customizer.sh com.mybank.app MyBankApp "My Bank" ABCDE12345
#   bash customizer.sh com.mybank.app MyBankApp "My Bank" ABCDE12345 --keep-demo
#
# What this does (identity mode):
#   1. Writes fork identity into gradle/libs.versions.toml (the single source of truth)
#   2. Runs ./gradlew syncForkConfig to propagate to iOS Config.xcconfig,
#      local.properties (Fastlane), and gradle.properties (rootProject.name)
#   3. Removes the demo showcase (scripts/remove-demo.sh) so the fork starts from a
#      clean, branded framework shell — this is the DEFAULT. Pass --keep-demo to retain
#      the Money-Toolkit demo (for exploring the framework's reference features).
#
# No source file scanning, no package renaming, no sync-dirs conflicts. The convention
# plugin derives all module namespaces from baseNamespace automatically. baseNamespace and
# fork identity are never touched by the demo removal.
