Long function definition should put equals and body on a newline

Issue created from fantomas-ui

The = and Http.main ... should be on the next line.

If the return type is declared, the behaviour is correct.

module FormatCode =

    open System.Net.Http

    let private format filename code config =
        let checker = Fantomas.FakeHelpers.sharedChecker.Force()
        let options = Fantomas.FakeHelpers.createParsingOptionsFromFile filename
        let source = SourceOrigin.SourceString code
        CodeFormatter.FormatDocumentAsync("tmp.fsx", source, config, options, checker)


    [<FunctionName("FormatCode")>]
    let run
        ([<HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = "{*any}")>] req: HttpRequest)
        (log: ILogger)
        : Async<HttpResponseMessage>
        = Http.main CodeFormatter.GetVersion format FormatConfig.FormatConfig.Default log req

Code

module FormatCode =

    let private format filename code config =
        let checker = Fantomas.FakeHelpers.sharedChecker.Force()
        let options = Fantomas.FakeHelpers.createParsingOptionsFromFile filename
        let source = SourceOrigin.SourceString code
        CodeFormatter.FormatDocumentAsync("tmp.fsx", source, config, options, checker)


    [<FunctionName("FormatCode")>]
    let run ([<HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = "{*any}")>] req: HttpRequest) (log: ILogger) = Http.main CodeFormatter.GetVersion format FormatConfig.FormatConfig.Default log req

Result

module FormatCode =

    let private format filename code config =
        let checker = Fantomas.FakeHelpers.sharedChecker.Force()
        let options = Fantomas.FakeHelpers.createParsingOptionsFromFile filename
        let source = SourceOrigin.SourceString code
        CodeFormatter.FormatDocumentAsync("tmp.fsx", source, config, options, checker)


    [<FunctionName("FormatCode")>]
    let run
        ([<HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = "{*any}")>] req: HttpRequest)
        (log: ILogger) = Http.main CodeFormatter.GetVersion format FormatConfig.FormatConfig.Default log req
