I came up with a working PoC for injections using NREPL. Is there a more straight-forward way to accomplish this?

The injection in this case is requiring pprint.

The code is easily referenced in a deps.edn alias:

:inject {:extra-deps {waffletower/repl-eval {:local/root "../repl-eval/"}
                      nrepl/nrepl {:mvn/version "0.7.0"}
                      refactor-nrepl/refactor-nrepl {:mvn/version "2.5.0"}
                      cider/cider-nrepl {:mvn/version "0.25.1"}}
         :main-opts ["-m" "repl-eval.nrepl"]}

While I could refactor this to instrument variable middleware and injection forms, is there some hook I am missing here? It was much much easier and cleaner to accomplish REPL initialization with leiningen.

I'm assuming by "injection" here you mean "evaluate some code on nREPL startup", right?

There's nothing in the existing CLI UI, although it'd be easy to add something like --init or whatever. CIDER itself injects a bit of code via cider-repl-require-repl-utils-code.

Usually when I write a defn form in emacs, the docstring is rendered in a nicer style (italics, in my case). What should I modify if I want to get that when I use macros that replace the defn form, like >defn from guardrails?
