Adding multiline string to a Yaml-cpp node

Question

How to add a multi line string as value to key using node ? I don't want to use emitter.

I want something like below code

Iphone: blah ... blah \n blah .... blah \n

I want to create the data similar to above programitically using a YAML::Node object.

Just set the string in your node:

YAML::Node node;
node["iphone"] = "blah ... blah \n blah .... blah \n"
std::cout << node;

If you're looking to have it output with multiple lines, instead of \n, you'll have to use an emitter; yaml-cpp doesn't support formatting output with basic node dumping. (Feel free to file an issue on the project page if you think it's worthwhile.)

Yes, I am looking a way to add multi line string to a node directly rather than using emitter. Is it possible to get convert a emitter to node ? – Bhanu Vanka Mar 07 '14 at 09:39
@user3389312, what do you mean? – Jesse Beder Mar 08 '14 at 01:55
I mean creating a YAML::Emitter with string literal data, so that the new lines are retained and final pass that emitter to node. – Bhanu Vanka Mar 08 '14 at 07:36
What do you mean "final pass that emitter to node"? – Jesse Beder Mar 09 '14 at 22:21
I meant to convert the emitter as a node – Bhanu Vanka Mar 10 '14 at 13:36
You can't convert an emitter to a node (this wouldn't make sense). What do you mean "as" a node? – Jesse Beder Mar 11 '14 at 13:55
Sorry for bad english :) – Bhanu Vanka Mar 12 '14 at 13:16
I meant to emitter to node conversion, which you said it is not possible at the moment. – Bhanu Vanka Mar 12 '14 at 13:17
Is it possible to sequence of nodes to a node using node object ? – Bhanu Vanka Mar 12 '14 at 13:18
Sorry, the language barrier is making this a bit difficult :) – Jesse Beder Mar 12 '14 at 15:29
I still am not sure what you're saying, but I'm guessing what you want isn't possible - you'll just have to use an `Emitter`. – Jesse Beder Mar 12 '14 at 15:29
