clj -m works from shell but not as alias

Question

Running the following at the command line:

clj -Acider -m "nrepl.cmdline" "--middleware" "[refactor-nrepl.middleware/wrap-refactor cider.nrepl/cider-middleware]"

Given:

:cider {:extra-deps {nrepl {:mvn/version "0.6.0"}
                                refactor-nrepl {:mvn/version "2.5.0-SNAPSHOT"}
                                cider/cider-nrepl {:mvn/version "0.23.0-SNAPSHOT"}}}

Works. But moving it to a :main-opts:

:cider {:extra-deps {nrepl {:mvn/version "0.6.0"}
                                refactor-nrepl {:mvn/version "2.5.0-SNAPSHOT"}
                                cider/cider-nrepl {:mvn/version "0.23.0-SNAPSHOT"}}
                   :main-opts ["-m" "nrepl.cmdline" "--middleware" "[refactor-nrepl.middleware/wrap-refactor cider.nrepl/cider-middleware]"]}

And running:

clj -Acider

Fails with:

Answer 1

I believe this is a known issue. The problem is the space between the middlewares. At the shell escaping is fine via "" but in the config file it is passed as a plain arg which then gets split into 2 since it is no longer escaped.

The common workarround for this is using a , instead of a space, since clojure treats it as a whitespace anyway.

:main-opts ["-m" "nrepl.cmdline" "--middleware" "[refactor-nrepl.middleware/wrap-refactor,cider.nrepl/cider-middleware]"]
