Class parameters expands unit for long lines

[dbrattli]

Issue created from fantomas-online

Code

type ISingleExpressionValue<'p, 'o, 'v when 'p :> IProperty and 'o :> IOperator and 'p: equality and 'o: equality and 'v: equality> () =
    abstract Property: 'p
    abstract Operator: 'o
    abstract Value: 'v

Result

type ISingleExpressionValue<'p, 'o, 'v when 'p :> IProperty and 'o :> IOperator and 'p: equality and 'o: equality and 'v: equality>
    (

    ) =
    abstract Property : 'p
    abstract Operator : 'o
    abstract Value : 'v

Problem description

Looks like class parameters are expanded into multiple lines where e.g unit will be written as:

(

) =

instead of

() =

Note that this seems to happen only for longer lines. Shorter lines will write () =.

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.

_{Did you know that you can ignore files when formatting from fantomas-tool or the FAKE targets by using a .fantomasignore file?}

Thanks for the report, this is a bit silly indeed.

@dbrattli I also noticed that the generic part and the constraints lead to not respecting the max_line_length.
If this bothers you, I would ask you to open an issue with the F# style guide and ask for clarification on how to deal with this.
