    You will also need a formatter that uses that style. Brittany for example. The default formattingProvider for HLS is ormolu, which I believe doesn't use this style, so you will have to change this setting.

    For Haskell I use Brittany with this config:

    Yeah I couldn't find anything at all which is really unfortunate. You could check out the config source code

    Turns out I prefer Brittany to Ormolu, I edited it so it hopefully looks less verbose all on one line

    I use Brittany and prefer it to Ormolu, because it aligns more things and it break lines that are too long automatically. I have recently tried to figure out how I could implement a solution to, but it is quite hard to figure out which parts of the code would be involved in such a change. And I don't really have enough time to make steady contributions, but I will probably try to make a few contributions sometime.

    I would say that development has stalled:
