Format multiline imports in hls (emacs)
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.

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

[ANN] Fourmolu 0.7.0.0
If I could nitpick here a bit, fourmolu is primarily a fork that is ormolu + configuration. It also happens to have a default configuration different from ormolu (https://github.com/fourmolu/fourmolu/issue/128), but it's not the primary motivation for fourmolu
That github link is broken: https://github.com/fourmolu/fourmolu/issues/128.
