Smart linebreak printer for pipe chains

[amiralies]

They are currently being formatted based on line width.
it would be good to allow user decide whether to break line on pipes or not.

for example this code gets formatted to a single line with default line width

let bazz = foo.bars->OptionEx.arrayValues->Map.String.fromArray

I found this more readable

let bazz =
  foo.bars
  ->OptionEx.arrayValue
  ->Map.String.fromArray

Yes, that’s something I’ve also been thinking about. As the line width gets longer, the width algorithm becomes less and less “nice”. There’s definitely an opportunity for improvement here.

There's a balance to be had, because for some pipes (e.g. if the above used local functions and was foo.bars->arrayValues->fromArray I'd rather it stay on one line. Perhaps trigger wrap based on the number of pipes (e.g. 3) rather than line width?
