[FR] Opening a new connection to an existing nREPL server

[arrdem]

I've found it convenient in the past to have severan nREPL connections to a single nREPL server. Especially when messing with expressions that take a while to evaluate. At present it's easy enough to start a new nREPL server (C-c M-j) but without inspecting the resulting nREPL server buffer for a host/port it's not trivial to open a new REPL buffer connected to the same server.

Obviously something I'm fully capable of working around, but it'd be a nice addition.

So, the auto-completion you get in cider-connect is not enough and you'd like a new command to "clone" a connection? I'm just trying to figure what exactly do you have in mind.

The auto completion has always been enough for me to connect to a previously started server. Is there anything you think it lacks?

[arrdem]

@bbatsov - That's exactly what I had in mind.

@Malabarba - In my experience which is now a few weeks stale, server/port auto complete only works on localhost. The context in which I would find a "clone" command interesting would be duplicating a connection (including reusing the SSH tunnel if possible) to another machine.

[Malabarba]

I see, then it's certainly a worthy feature. I didn't know it only works with localhost.
Instead of a whole new command, we could build this into cider-connect. For instance, it could offer to clone the current connection if invoked directly from a repl buffer.
Another option is to include currently active connections during host completion.

If we do this the command will end up doing too much IMO. Finding the balance is always hard. Btw, this is related to the portscanner feature request as well.
