emit multi-line string scalars

[g-pechorin]

IIRC there are ways to emit multi-line strings as "not just a really long string"

is this something that fkYAML can be told to do? I can parse existing documents, but, I want fkYAML to emit my really long strings across multiple lines if possible

Unfortunately fkYAML currently doesn't support emit multi-line strings from a long string, but there are ways to achieve that using line folding or block literal style.
The major reason of fkYAML not having the feature is, multi-line strings is much of presentation details. One may split a long line more frequently. Or another may want to emit some scalars across multiple lines but keep the others in a singe line.

Maybe we can start with the block literal style which is simpler but with which a long string can still be emitted across multiple lines as follows:

--- # single-line, long version
single line: "Assume this is a loooooong string.\nWe might want to emit this line across multiple lines.\nThere are some ways but not yet implemented in fkYAML."

---
multiple lines using block literal style: |-
  Assume this is a loooooong string.
  We might want to separate this line across multiple lines.
  There are some ways but not yet implemented in fkYAML.

Due to its simplicity, there are some downsides:

• A long string can only be split at line breaks.
• Contents are limited to a plain text, i.e., no escapes.

Is that going to help you?
