# @author Dominik Hadl
# @dependencies This script requires that you have p7zip package installed, prefferably through Homebrew.
#
# @description   This script will automatically find all .json files in your $BUILT_PRODUCTS_DIR and will compress them to the LZMA (7z) format.
# 				In the process it will also delete the original .json files - but only in the build folder.
#
# @usage
# 				1. Create a new build phase (Run script) in your target in Xcode
# 				2. Copy the script below
# 				3. Add a preprocessor macro to both Debug and Release called "LZMA_7ZIP_SUPPORT" to enable
#---------------------------------------------------------------------------------------------------------

# Get preprocessor macros
MACROS="${GCC_PREPROCESSOR_DEFINITIONS}";

# Check if LZMA_7ZIP_SUPPORT is set
if [[ $MACROS == *LZMA_7ZIP_SUPPORT* ]]; then
	echo "Compressing JSON files into 7z."

	# Path to P7ZIP (modify if needed)
	P7ZIP="/usr/local/bin/7z"

	# Check if command exists
	command -v ${P7ZIP} > /dev/null || exit 0

	# Disable spacing by space for a while
	oIFS=$IFS
	IFS=$'\n'

	# Find the .jsons, compress them and delete the .json files
	find "$BUILT_PRODUCTS_DIR" -name '*.json' | while read -r i; do
	JSON_NO_EXT=${i%\.*n}
	${P7ZIP} a "${JSON_NO_EXT}.7z" "$i"
	rm -rf "$i"
	done

	# Set back the spacing
	IFS=$oIFS
else
	echo "7z compression is disabled. Please set the preprocessor macro to enable."
