does customizing a repl consist of having an alternate (different from clj) executable for starting the repl, or is there a facility in tools.deps to customize it? e.g., customize the printing function, or ensure that certain code is run before the repl starts

Once you have a repl, you can start a nested repl within it with whatever customizations you want. But I think this an area ripe for better options.

looks like I can't put a system-global user.clj file on the classpath automatically, is that correct?

(due to "only the last :paths is kept and others are dropped")

you can certainly start a different main method rather than clojure.main and give yourself a souped up repl @gfredericks

@ghadi but that requires passing args each time, right?

si

alias repl='java $(cat jopts) -cp $(clojure -Spath) clojure.main -m gfredericks.fave.repl'
