empty String Serializing to nothing

[dashwang]

yamlbeans version: 1.09, 1.11

----- 

Here's my code:

public class MockUser {
    public String name;
    public String sex;
}

MockUser user = new MockUser();
user.name = "";
user.sex = "man";

YamlWriter writer = new YamlWriter(new FileWriter("/tmp/output.yml"));
writer.write(user);
writer.close();

----

dashwang@MBP ~# cat /tmp/output.yml

name:
sex: man

But what I want is:

name: ""

sex: man

---

When I use C++ yaml-cpp library to parse /tmp/output.yml, I got bad conversion exception.

I wonder whether YamlBeans's output is YAML standard or not.

Seems you are right. I've pushed a fix.

The YAML standard is an absolute mess. :)

Cheers,

static public class MockUser {

    public String name;
    public String sex;
}

static public void main (String[] args) throws Exception {

    MockUser user = new MockUser();
    user.name = "";

    StringWriter w = new StringWriter();
    YamlConfig config = new YamlConfig();
    config.writeConfig.setWriteDefaultValues(true);

    YamlWriter writer = new YamlWriter(w, config);
    writer.write(user);
    writer.close();
    System.out.println(w);

    YamlReader reader = new YamlReader(w.toString());
    MockUser user2 = reader.read(MockUser.class);
    System.out.println("---");
    System.out.println("name: '" + user.name + "' -> '" + user2.name + "'");
    System.out.println("sex: '" + user.sex + "' -> '" + user2.sex + "'");
}
