# desktop-only-prep.sh — Prepare source tree for a desktop-only (JVM) build.
#
# Usage:
# ./scripts/desktop-only-prep.sh
# DESKTOP_ONLY=true ./gradlew :desktop:packageUberJarForCurrentOS
#
# This script comments out Android-specific blocks in module build scripts so
# Gradle can configure without the Android SDK. It is designed for Flatpak and
# other sandboxed Linux packaging environments.
#
# Prerequisites:
# npm install -g @ast-grep/cli
# OR
# pipx install ast-grep-cli
#
# The companion in-code guards in build-logic convention plugins handle:
# - Skipping Android/iOS plugin application (KmpLibraryConventionPlugin)
# - Skipping iOS targets (configureKotlinMultiplatform)
# - Creating a placeholder androidMain source set
# - Excluding Android-only modules from settings.gradle.kts
#
# This script handles what can't be done in-code:
# - `kotlin { android { ... } }` blocks in module build.gradle.kts files
# - `androidMain.dependencies { ... }` blocks with project dependencies to
# excluded modules (e.g., projects.core.barcode, projects.core.api)
#
# To reverse: `git checkout -- .` or rebuild from clean source.
