I kind of disagree with including user specific REPL tools in the project configuration.
Usually, cider-nrepl middleware is added by the editor when launching the REPL process. With lein tools like hashp were easy to add to the
~/.lein/profiles.cljbut I guess it isn't as easy with~/.clojure/deps.ednbecause you'd still need to refer to a alias created there to enable those deps... hmm.There was a problem hiding this comment.

Yeah, agree too, was just for my own convenience here.
Use specific aliases need to be activated, so if a project has say a
bb devtask bundled for easy startup, maybe there could be options in the task to specify those aliases, or actually, I wonder if babashka supports user-specific task files, since this user-specific customization needs kind of two things 1) deps.edn 2) starting with custom arguments...
