Generics error when breaking line

[fc1943s]

Issue created from fantomas-online

Code

module Services =
    /// Builds a Stream Resolve function appropriate to the store being used
    type StreamResolver(storage: Storage.Instance) =
        member __.Resolve
            (
                codec: FsCodec.IEventCodec<'event, byte [], _>,
                fold: ('state -> 'event seq -> 'state),
                initial: 'state,
                snapshot: (('event -> bool) * ('state -> 'event))
            )
            =
            match storage with
            | Storage.MemoryStore store ->
                Equinox.MemoryStore.Resolver(store, FsCodec.Box.Codec.Create(), fold, initial).Resolve
            | Storage.EventStore (gateway, cache) ->
                let accessStrategy =
                    Equinox.EventStore.AccessStrategy.RollingSnapshots snapshot

                let cacheStrategy =
                    Equinox.EventStore.CachingStrategy.SlidingWindow(cache, TimeSpan.FromMinutes 20.)

                Equinox.EventStore.Resolver<'event, 'state, _>(gateway, codec, fold, initial, cacheStrategy, accessStrategy).Resolve

Result

Problem description

Please describe here fantomas problem you encountered.

Before:

After:

Source code:
https://github.com/jet/dotnet-templates/blob/master/equinox-web/Web/Startup.fs
(dotnet new -i Equinox.Templates --> dotnet new eqxweb -t -e)

EDIT:
If I remove the generic type alias the formatting stops breaking the line, but still crossing the configured 120 limit

Does the configuration options support something like this?

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.

Hey, thanks for reporting this issue. It rings a bell 😅.

Does the configuration options support something like this?

No, please upvote #501 for this.

Lastly, you might be interested in the fsharp_alternative_long_member_definitions setting.
