for clj I use C-c C-k to invoke (do (load-file "filepath")(in-ns 'namespace)) to reload a file and switch to its' namespace. I'm having difficulty figuring out an equivalent thing for cljs. If I run load-file and then in-ns it works but it leaves an extra []\n in the repl output so I've been trying to sort it out. In the meantime I was wondering why inf-clojure has these as separate commands, do people usually load and set-ns as different commands or is there a different common workflow?

I just require the namespace. I’m not sure that clojurescript has a notion of load file?

and using load-file means each form is essentially fed into a repl so you don't get line number metadata and source therefore won't work

it seems cljs does have load-file. Interesting that you see extra input. If you just type in (load-file "whatever") in the repl do you see the extra input?

the great thing about inf-clojure is that there's not much it does on top of a repl. So if you are seeing that output it is highly likely that that is just what the repl itself is returning
