Clojurians Log v2

Is there any specific requirement that I need to get Jack in Running? I’m trying to start a project whose deps.edn file is not in the root directory but nothing happens. It works if I open VSCode in a way that deps.edn is in the root. Is there a way to change this?

A believe a deps.edn file is required at the root of the opened project. CC @pez

That seems to be the case; I was wondering if there’s a workaround for this

I don't think so. There's a note about that requirement here: https://calva.io/connect/#jack-in-let-calva-start-the-repl-for-you

Quick question: is there a way to specify a namespace to be auto-loaded on jack-in? I’ve been having to manually eval my user.clj file and can’t seem to find a setting for that. Maybe it’s deps.edn specific?

You could specify with afterCLJReplJackInCode

Yeah, just tested it and it would work. Inside of settings.json 👉 calva.replConnectSequences create/edit a sequence and in the object add: "afterCLJReplJackInCode": "(ns my-ns.core)"

Full object was…

{
            "name": "Leiningen Ex",
            "projectType": "Leiningen",
            "cljsType": "none",
            "afterCLJReplJackInCode": "(ns my-ns.core)",
            "menuSelections": {
                "leinAlias": null,
                "leinProfiles": [
                    "dev",
                    "repl",
                    "user"
                ]
            }
        }

Hm that doesn’t seem to work for my deps.edn project. I see (ns user) get evaluated resulting in nil, but it doesn’t seem to actually load the namespace (all of the symbols are still unresolved)

I keep having trouble with shadow-cljs — I start my shadow app with: npx shadow-cljs watch frontend and connect to an existing repl and use the :frontend option — When I try to evaluate something I get: No available JS runtime.

Try having a Clojure file from the project opened when you Jack in.

I tried that already, but it did not make any difference

It’s not a big deal — I have essentially some openfaas functions and each of them has its own directory and deps.end file

If I have a file, dev/user.clj, and in my deps.edn I have {:paths ["src" "dev"]}, after I jack-in the vars I define in the user namespace exist.

By default, tools.deps includes the "src" path, so if you have src/user.clj that file will be loaded even if your deps.edn is just {}

So, you don't need to use a repl connect sequence, this is built in to tools.deps and I think leiningen. The file just needs to be on your classpath.

I'm guessing it's a browser app. Do you have the app loaded in the browser?

If it's a browser app, the browser is used as the runtime, so it needs to be loaded in order for evaluations to work in the editor/repl.

At least, I think I'm understanding that correctly 😄 . I've had a similar issue in the past when doing browser-based cljs dev.
