Add toLines() trait

[sormuras]

Interested in adding a trait for a multi-line toString() variant that indents each nested component on a best-effort basis?

Something similar to https://sormuras.github.io/blog/2020-05-06-records-to-text-block.html

Hi Christian,
yes, maybe with a syntax closer to JSON, with the record name in comment ?

[sormuras]

Ho! 🤓

Sure, will create a PR later. Perhaps one with taking arguments for the style and indentation strings...

.toLines(Style.JSON, " ") {...}

Return type?

• String (with configurable new line character, of course)
• List<String>
• Stream<String>

I wonder if a String is not enough.
I'm not a fan of toLines(JSON), i would prefer two methods, one toJSON() and one toHumanReadableJSONLike() which uses JSON + comment + several lines as format

see https://github.com/forax/record-util/blob/master/src/main/java/com/github/forax/recordutil/JSONTrait.java for a skeleton implementation (no recursion, etc)

I've implemented a version that generates a human readable JSON
