Issue created from fantomas-online

Code

type andSeq<'t> =
    | AndSeq of 't seq
    
    interface IEnumerable<'t> with
        member this.GetEnumerator(): Collections.IEnumerator =
            match this with
            | AndSeq xs -> xs.GetEnumerator() :> _

Result

type andSeq<'t> =
    | AndSeq of 't seq


    interface IEnumerable<'t> with
        member this.GetEnumerator(): Collections.IEnumerator =
            match this with
            | AndSeq xs -> xs.GetEnumerator() :> _

Problem description

Fantomas will add an extra newline every time formatter runs. In the online tools you will only see one extra newline, but if you copy the output back to the input it will keep adding newlines.

Fantomas should consider running formatter twice in tests to see that the output is stable and will not change every time the formatter runs.

Fantomas v4.4.0-alpha-007

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?}
