未实现的方法

function get_declare_array(){
//声明 declare_array 名的数组
	declare -a declare_array
    

	git diff --cached --name-only | while read line;
	do
    file_name=`echo $line | awk '{print $0 }'`
    if [[ $file_name == *.h ]]; then
    	declare_array[${#declare_array[@]}]=`echo $file_name`
    	echo $file_name
	fi
	done
	return ${declare_array[@]}
}

1.声明 declare_array 名的数组 declare -a declare_array 2 .git diff --cached --name-only | while read line; do

    git diff --cached --name-only | while read line; do
     echo "暂存区中有差异的文件: $line"
   done

function get_impl_array(){
	declare -a declare_array
	git diff --cached --name-only | while read line;
	do
    file_name=`echo $line | awk '{print $0 }'`
    if [[ $file_name == *.m ]]; then
    	declare_array[${#declare_array[@]}]=`echo $file_name`
    	echo $file_name
	fi
	done
	return ${declare_array[@]}
}
