Add Scalafmt

[laughedelic]

• no more moving code around, same formatting for everyone: clearer diffs, easier to review PRs
• Scalafmt released v1.0 some time ago and is now v1.1, so it's considered quite stable
• Sbt has recently adopted Scalafmt for it's (quite big) codebase
• There's an ongoing community discussion about creating a standard style guide, which is very good

[laughedelic]

@eparejatobes do you have anything against it?

[eparejatobes]

Nothing against scalafmt per se, a lot against the "official" style guide(s).

[laughedelic]

I read it as you're fine with using it with certain adjustments to the formatter configuration.

If certain means wiping out defaults completely, yes.

[laughedelic]

I guess, you meant to reply instead of editing my message.

wiping out defaults completely

I don't get it. You want to write your own formatting config from scratch and maintain it?

[eparejatobes]

I don't get it. You want to write your own formatting config from scratch and maintain it?

If I'm using scalafmt, yes.

[eparejatobes]

Yes, I wanted to reply, sorry :laughing:

[laughedelic]

If I'm using scalafmt, yes.

Why? Is the default one so bad and unappealing to you? (did you check it?) Why wasting time doing it from scratch instead of reusing the default and tweaking a couple of things that you don't like? (I don't like it either)

Anyway, if you are really going to do it, it's fine with me. I just want to have a unified automatic formatting and simplify diffs in PR reviews..
