Luminus + Calva = Smooth Getting Started w/ Clojure development

Showcase Your Projects and Libraries

I’ll write a guide about using Calva with Duct, as well as file a PR on the Duct template so that things are as streamlined as they are with Calva+Luminus.

Until then. These are the steps for using Calva with a fresh Duct project w/ ClojureScript frontend adding the custom cljs settings yourself (w/o frontend, it is not much to write about :smile:):

  1. Create the project:
    lein new duct my-duct-cljs +site +example +cljs
  2. Open the project in VS Code:
    code my-duct-cljs/
  3. Create a VS Code project folder settings file .vscode/settings.json, and paste this:
    {
    "calva.replConnectSequences": [
        {
            "name": "Server only",
            "projectType": "Leiningen",
            "afterCLJReplJackInCode": "(do (dev) (go))",
            "cljsType": "none"
        },
        {
            "name": "Server + Client",
            "projectType": "Leiningen",
            "cljsType": {
                "dependsOn": "lein-figwheel",
                "connectCode": "(do (dev) (go) (println \"Server started\") (cljs-repl))",
                "isReadyToStartRegExp": "Server started",
                "printThisLineRegExp": ":duct.server.http.jetty/starting-server"
            },
            "menuSelections": {
                "leinProfiles": [
                    "dev",
                    "repl"
                ]
            }
        }
    ]
}
    See Calva docs about Custom Connect Sequences if you are curious about the settings.
  4. Issue the command Start a Project REPL and Connect (aka Jack-in),
    ctrl+alt+c ctrl+alt+j
  5. Wait for the Calva says output channel to say CLJS REPL ready to connect. Please, start your ClojureScript app.
  6. Open your web browser, pointing it to 127.0.0.1:3000/example.
  7. Hack away on your project!

If anyone tries this, please let me know how the instructions worked. It’ll help me get the Calva docs right. :heart:
