xcode.sh

# Base function:
# Takes two arguments: a directory and a name for Xcode.
function open_with_xcode {
	targetDirectory=$1
	xcodeApp=$2
	# If there's a workspace file, open that.
	didFindXCWorkspace=`find $targetDirectory -depth 1 | grep -i .xcworkspace | wc -l | sed -e 's/^ *//g' -e 's/ *$//g'`

	# Testing a glob with -d, like
	# if [ -d *.xcworkspace ];
	# just yields errors when it doesn't.
	# Stupid shell.
	if [ $didFindXCWorkspace != 0 ]; then
		open -a $xcodeApp $targetDirectory/*.xcworkspace([1])
		return
	fi
	didFindXcodeproj=`find $targetDirectory -depth 1 | grep -i .xcodeproj | wc -l | sed -e 's/^ *//g' -e 's/ *$//g'`
	if [ $didFindXcodeproj != 0 ]; then
		open -a $xcodeApp $targetDirectory/*.xcodeproj([1])
		return
	fi
	echo "No .xcworkspace or .xcodeproj found."
	return 1
}
