How to use running Docker swift container as REPL

[stardiviner]

My Linux installed swift binary failed many times. So I give up. Until it is easy to install on my Arch Linux. I use Swift Docker image to get a running Swift REPL. and other swift binaries. But I don't know how to use running Docker swift container as swift REPL and binary path.

• for container Swift REPL, Emacs has an package docker.el can attach started container. so I can get an REPL buffer in Emacs. But if I want to make the REPL buffer work with swift-mode. I don't know how to set it up.
• for container binary path to be available for Emacs's swift-mode. I don't know how to do this.

To change the command temporary:

1. C-u M-x run-swift.
2. Enter docker run --rm --privileged -it swift swift.

To save the command for future sessions:

1. M-x customize-group.
2. Enter swift-mode:repl.
3. Change Swift Mode:Repl Executable to docker run --rm --privileged -it swift swift.
4. Click State and Save for Future Sessions.
5. M-x run-swift.

Thanks, this works even send code to REPL. But the repl buffer name is same with command. Can you add code to always rename REPL buffer to a specific name like *swift* as other REPL buffer does.

It is intentional to distinguish multiple processes with different command line parameters like iOS app debugger and Swift module debugger processes. How about *Swift [docker run --rm --privileged -it swift swift]*?

I see. Thanks

How about Swift [docker run --rm --privileged -it swift swift]?

That's better. so that other Emacs packages like ob-swift can match it simpler. Thanks
