How to connect to a remote running Lisp

[vindarel]

Asked again in https://stackoverflow.com/questions/46499463/hot-debug-and-swap-in-common-lisp/46501704 I agree there should be a tutorial somewhere and it's a good fit for the cookbook.

Some notes I took for myself. I largely agree we should have a tutorial out there. In the CL Cookbook ?

Reading http://readevalprint.tumblr.com/post/101841449553/its-alive-the-path-from-library-to-web-app :

Another option is hot swapping all the changes. For this purpose my hunchentoot server also starts a swank server like this:

(defun start-app (&optional (port 8080))
  (handler-case (swank:create-server :dont-close t)
    (error ()))
    …

Swank is, of course, the server-side component of SLIME. It runs on a port that is not accessible remotely and can only be connected to locally or via SSH tunnel. I use the latter to connect SLIME on my PC to Swank running on my server, which allows me to apply various fixes without restarting, either from the REPL or by using C-c C-c to recompile some function.

Connect to a remote Slime server:

• Install a Common Lisp implementation on the server. (E.g. sbcl, clisp, etc...)
• Install quicklisp on the server.
• Load SWANK with (ql:quickload :swank)
• Start the server with (swank:create-server). The default port is 4005. [On your local machine] Create a SSH tunnel with ssh -L4005:127.0.0.1:4005 [remote machine]
• Connect to the running remote swank server with M-x slime-connect.
• The host should be 127.0.0.1 and the port 4005.

That's a good idea. I am currently using a docker setup to connect to a remote lisp (resp. dockerized lisp) Maybe it would be useful to describe this setup? (it's not perfect though, I could not get filename translation working.)

Sure! Can you present as "A Recipe for connecting to a remote lisp"? Love to take that PR.
