Extra blank line with doc.toString

[srishina]

Hi,

Many thanks for the excellent library.

I have a YAML document that I need to modify and later use toString to get the YAML representation. However for the following

forecast: "How is the weather today?\nIs it good?"

after toString

    forecast: "How is the weather today?
--> there is an extra blank line here
      Is it good?"

Is it expected? or is there an option that I can use to remove the extra blank line?

In YAML, a double-quoted string needs to use \n\n to represent a newline, as a single \n would effectively get parsed as a space.

Thank you!

        const yamlData = `name: me\nforecast: "How is the weather today?\\nIs it good?"`;
        console.log("yamldata: ", yamlData)
        const yamlDoc = YAML.parseDocument(yamlData);
        console.log(yamlDoc.toString())

should result in:

`name: me
forecast: "How is the weather today?

Is it good?"`

Is my understanding right?

I'm not really sure what you're asking me. The library's output is valid YAML.

I think, I understand now. I was asking about the blank line , but I think as YAML needs \n\n it gets inserted in Document.toString function.
