I have two questions, but only one here (companion question is on #clojurescript channel). When I run clj -M --main cljs.main , Clojure on the JVM creates a repl in a firefox browser instance, but does not present a repl prompt at the terminal. I mention this only to show the minimum necessary to get a browser repl loaded whether or not accessible. Calva uses cider.piggieback middleware on a JVM repl. Once cider.piggieback establishes the browser repl, when I send say (+ 1 1) from the repl prompt, does it go to the cider.piggieback middleware first and then get passed to the browser repl, or does it go direct to the browser repl?

@brandon.ringe: I think this should be added to Clava docs? WDYT? I do have a question (probably more VSCode related) : Can these settings be done on a per project ? I would like to have debugging and logging options enabled only for project-x when I open it, not all projects.

    },

(I found it in a reply form @pez on this channel). I needed it to be able to debug a clojure app that used some Java libraries. In the above, I change slf4j logging and also enable VM debug mode
