编辑单个YAML值而不更新其余YAML的格式（YAML CPP）[重复]

Question

# Config file 
package_name: "auto_mapping_ros"

csv_filepath: "/csv/sequence"

# Non ROS Map Values
non_ros_map_width : 1000

package_name: !<!> auto_mapping_ros
non_ros_map_height: 1355
csv_filepath: !<!> /csv/sequence

YAML::Node node, _baseNode = YAML::LoadFile(auto_mapping_yaml_path); // gets the root node
_baseNode["non_ros_map_width"] = 1355; // edit one of the nodes
std::ofstream fout(auto_mapping_yaml_path);
fout << _baseNode; // dump it back into the file

Answer 1

从YAML文档https://YAML.org/spec/1.2/spec.html#ID2767100:

注释是演示文稿的详细信息，不能对序列化树或表示图产生任何影响。

YAML将按设计删除注释。
