Elm upgrade placing broken version number in elm.json

[Muzz]

Finally getting around to seeing if i can update an old project of mine. And for some reason the elm.json that is getting generated has a carriage return in it. This is on windows 10 with the latest elm-format, and elm, with the latest elm-upgrade.

Assistance would be appreciated.

-- PROBLEM WITH VERSION ----------------------------------------------- elm.json

I got stuck while reading your elm.json file. I was expecting a version number
here:

8| "elm-version": "0.19.1\r",
^
I need something like "1.0.0" or "2.0.4" that explicitly states all three
numbers!

Huh, that's interesting. I'm guessing it's due to nodejs automatic newline conversion? I'd think it'd have to be this line where things go wrong https://github.com/avh4/elm-upgrade/blob/master/upgrade.js#L130 Does fs.writeFileSync and/or JSON.stringify insert \r on Windows? If we could update that function to not do that, I'd think that should fix things.

Ah, I realized what I just wrote is probably wrong. It's more likely that the problem is here https://github.com/avh4/elm-upgrade/blob/master/upgrade.js#L175 we need to strip out the \r when parsing the version number from elm --version.

Thanks for looking into that so quickly!
