Strings with newlines should be encoded as multiline literals #405
Closed
Description
This code:
let testYaml = #"""
script:
- |
if [[ some test ]]; then
echo "Hello world!"
fi
"""#
let loaded = try Yams.load(yaml: testYaml) as? [String: Any]
print(loaded as Any)
prints
Optional(["script": ["if [[ some test ]]; then\n echo \"Hello world!\"\nfi"]])
But when I try to encode something with newlines:
let dump = try Yams.dump(object: loaded)
print(dump)
prints
script:
- "if [[ some test ]]; then\n echo \"Hello world!\"\nfi"
instead of using a multiline literal, it instead encodes them as \n. This is confusing, since Yams handles parsing these fine, but is unable to handle encoding them. If you'd like to maintain the current behaviour, I'd suggested adding something like this to Emitter.Options:
enum NewLineHandlingStrategy {
/// Encode newlines in strings as \n
case escapeNewlines
/// Encode newlines in strings with a literal block, ie |
case literal
/// Encode newlines in strings with a foided block, ie >
case folded
}Here's a reference on these
