[Beginner] Commas are poorly formatted in records

[alexandru-calinoiu]

Hi,

Just working at setting up my work env for haskell, been working with elm for some time now and I love the way records are formatted with a starting comma. Can't figure out how to turn

data Employee = Employee
  { employeeFirstName :: String,
    employeeLastName :: String,
    employeeAge :: Int,
    company :: String,
    email :: String,
    salary :: Int
  }

into

data Employee = Employee
  { employeeFirstName :: String
    , employeeLastName :: String
    , employeeAge :: Int
    , company :: String
    , email :: String
    , salary :: Int
  }

I know that the current formater used by the extension is stylish-haskell at least I hope it is.

Hi, this question is generally more related to the different haskell formatters than the VsCode plugin.

HLS supports a number of formatters, you will probably have to pick your poison as none of them quite feel like elm-format.

I think what would tick your box for record formatting is brittany, you can try it out online here. You can change your formatters via File > Preferences > Settings > Extensions: Haskell > Formatting Provder : Brittany.

If you want something quite similar to elm-format in spirit, I think (really just opinion, nothing official) ormolu is a nice alternative as it is a zero configuration formatter with strong opinions on your formatting and once you are used to it, feels similar to elm-format. Alternatively, fourmolu is quite the same but with a little more configuration options.

OK, figured it out, thanks a lot for your help!
