Hi @eapyl Indeed you are right. I'm following pyyaml behaviour here but, as pointed out in this bug, the yaml spec says keys should be unique.
The problem should probably be caught earlier, in the parsing step (e.g. https://github.com/MaybeJustJames/yaml/blob/2.1.0/src/Yaml/Parser.elm#L454) since, at decode time, we no longer know there are duplicate keys.
I would gladly accept a PR for this because I probably won't be able to fix this in the near term
Hello @MaybeJustJames, thank you for pointing out the source code where it can be fixed. I have prepared a small PR. Could you please check it and comment? thanks
Hello,
It seems like the library ignores duplicated keys silently
and it seems like cause
Dict.fromList
is used on the list without duplication check. Is it expected behavior? It feels for me that it should produce an error in such cases. Or am I wrong? Thanks
