# Created by Gautier Pelloux-Prayer on 2014/10/09.
# This script will search for resources contained in Resources/ folder but not
# present in xcode build project project.pbxproj. Since we do not use folder
# references (because of http://vocaro.com/trevor/blog/2012/10/21/xcode-groups-vs-folder-references/),
# it helps keeping resources synced.
# Basically, the script will set a red tag to every files not added in the xcode project. User will then
# have to drag&drop these into xcode project. Red tags are automatically reset by the script on execution


if [ $# != 0 ]; then
	echo "Usage: $0"
	exit 0
fi

if ! which tag &>/dev/null; then
	echo "Please install tag: port install tag or brew install tag"
	exit 1
fi

# quit on first error
set -e

# go where the script is
cd $(dirname $0)

echo "**********************
Done. Created red tags for non-synced files:
${non_synced_files}.

Drag and drop these files into your xcode project. You can go to the folder using:
	open $PWD/../Resources
Then use search feature and type 'red', select the red tag and go!
