I have trouble running a remote REPL session via Tramp.

Recent CIDER gives the following error, and it is caused by some weird escaping:

[nREPL] Starting server via clojure -A:cider -Sdeps '{:deps {nrepl {:mvn/version "0.5.3"} org.clojure/tools.nrepl {:mvn/version "0.2.13"} refactor-nrepl {:mvn/version "2.4.0"} cider/cider-nrepl {:mvn/version "0.20.0-SNAPSHOT"}}}' -e '(require (quote cider-nrepl.main)) (cider-nrepl.main/init ["refactor-nrepl.middleware/wrap-refactor", "cider.nrepl/cider-middleware"])'...

The command line at the remote host is the following: bash /home/dottedmag/bin/clojure -A:cider -Sdeps {:deps {nrepl {:mvn/version "0.5.3"} org.clojure/tools.nrepl {:mvn/version "0.2.13"} refactor-nrepl {:mvn/version "2.4.0"} cider/cider-nrepl {:mvn/version "0.20.0-SNAPSHOT"}}} -e (require (quote cider-nrepl.main)) (cider-nrepl.main/init \ ["refactor-nrepl.middleware/wrap-refactor", "cider.nrepl/cider-middleware"]) — note the \ in cider-nrepl.main/init

Before I upgraded there was another \ added, before second middleware in the list of middleware passed to init, and it produced different error message.

@dottedmag Recent CIDER versions don’t use cider-nrepl.main/init at all. They directly delegate the init to nREPL.

@bozhidar Thanks, apparently I had old CIDER loaded even after el-get-upgrade, restart of Emacs fixed it.

@bozhidar Is there a non-hackish way to set an environment variable for a remote clojure instance?

Nevermind. I only need to set it for a .so I'm loading, so I can as well do (jna/invoke Void c/setenv "WHATEVER" "i need"), as I'm going to use JNA for invoking native code anyway.
