Code and result

let a =
    Html.button [ prop.style [ style.marginLeft 5 ]
                  prop.onClick (fun _ -> setCount (count - 1))
                  prop.text "Decrement" ]

Problem description

Violation of the new "avoid name sensitive alignments" stuff in the F# formatting guidelines. Should be something like this:

let a =
    Html.button
        [ prop.style [ style.marginLeft 5 ]
          prop.onClick (fun _ -> setCount (count - 1))
          prop.text "Decrement" ]

Extra information

• The formatted result breaks by code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.

Default Fantomas configuration

Please use fsharp_disable_elmish_syntax=true.

[cmeeren]

Thanks! To be compliant with the style guide by default, will that be made true by default in an upcoming version? (This also goes for fsharp_alternative_long_member_definitions=true.)

Also, do you know when you plan on releasing these name-sensitive alignment changes in a non-alpha version? (I'm using the F# formatting VS plugin, and I think it only uses non-alpha versions.)

[nojaf]

Yes, I'm considering changing the default value to true and have people enable Elmish instead of having it out of the box.
Sorta, inversing the setting.
However, this requires a major version.

Could you please point why fsharp_alternative_long_member_definitions should be enabled? (separate isssue please)
fsharp_alternative_long_member_definitions matches the GR style guide and the current default should match the update MS style guide.

Also, do you know when you plan on releasing these name-sensitive alignment changes in a non-alpha version?

There still are some issues with the changes of the style guide. See #1341
