Weird indentation of fun body about fantomas HOT 4 CLOSED

This is a dup of #40.

As an aside, an option to disable alignment of code (except multi-line lists, records etc) would be fantastic :).

Can you elaborate? What kind of alignment are you referring to?

from fantomas.

Sorry, didn't find that one. Regarding alignment, the example given causes some kind of alignment, apart from the indentation. Alignment of code is a maintenance problem. The convention for lists etc is to align the items, for example

let x =
    [ "foo"
      "bar"
      "baz" ]

and it looks nice even though it's dangerous -- dedent code like that with VS and everything explodes. One example where Fantomas aligns is

[] |> List.choose (function
    | Some _ as x -> x
    | None -> None)

where it aligns the pipes under the function keyword.

Even more problematic would be inline alignment such as

let x =
    { some =   "foo"
      record = "bar"
      here =   "baz" }

but that doesn't seem to have caught on in the F# world, thankfully :).

So, the option I'd love would be to use plain indentation for everything but [, { and [| constructs (might've missed a case or two where alignment is canon).

However, it looks like #40 will solve my immediate problem.

Thanks for the explanation.

I understand your reason, but we cannot anticipate users' indentation behaviours. Fantomas can only ensure that at current situation indentation is correct.

I have to disagree. Although users can easily misalign elements inside [, {, [|, their alignments are canonical in F#. You can always set semiColonAtEndOfLine option to insert ; in the end of each element. Then you don't have to worry about misalignment anymore, the code can be parsed even if indentation among elements is off.

We're in agreement – I said plain indentation for everything but [, { and [|, where alignment is canonical.

As a closing comment, perhaps, thank you for this important and useful project!
