There was a problem hiding this comment.
Would you mind reverting this, and creating a separate test for the roll group syntax?
Got to make sure that the other syntax still works, and that the group roll syntax works / throws the correct errors 😄

If you export a
DiceRollwith roll groups, like with notation{d20}and then import the result, you will get an errorTypeError: value must be one of ResultGroup, RollResults, string, or number.This PR solves it by modifying
ResultGroup.addResultto accept a POJO, doing some very rudimentary validation, and instantiate the rich classes.Full JSON validation on import might be nice, but it would bloat the library. Perhaps it could be separated out into multiple packages, (Core, Import?) but that's quite an undertaking.
I also made a small repo that shows the bug: https://github.com/aarku/rpg-dice-roller-import-bug/blob/main/index.js
For testing, I decided to simply make the notation that gets exported/imported contain
{}.Hope it helps
