Issue starting application from lein template

[tjb]

Hello everyone! I recently created a new lein template and I have received the following error in the new repl window

clj::shadow.user=> 
; Debugger initialized
; Evaluating 'afterCLJReplJackInCode'
clj::shadow.user=> 
(start)
; Syntax error compiling at (.calva/output-window/output.repl-file:14:1).
; Unable to resolve symbol: start in this context

I noticed in the settings.json file that this is the configuration

    "calva.replConnectSequences": [
                {
            "name": "Server only - test-app",
            "projectType": "Leiningen",
            "afterCLJReplJackInCode": "(start)",
            "cljsType": "none",
            "menuSelections": {
                "leinProfiles": [
                    "dev"
                ]
            }
        },
        {
            "name": "Server + Client – test-app",
            "projectType": "lein-shadow",
            "afterCLJReplJackInCode": "(start)",
            "cljsType": "shadow-cljs",
            "menuSelections": {
                "leinProfiles": [
                    "dev"
                ],
                "cljsLaunchBuilds": [
                    "app",
                    "test"
                ],
                "cljsDefaultBuild": "app"
            }
        }
    ]
}

However, the (start) function is not found. Prior to the new repl window the application had no problem starting up. I apologize if this is not enough information as I am new to Clojure and unsure what else to add for this bug.

The command I used to generate the template is lein new luminus test-app +cljs +shadow-cljs +re-frame +postgres.

I am selecting Server + Client for the repl.

I seems the fix is to modify this settings file to be "afterCLJReplJackInCode": "(user/start)",

I think we need to make calva require (refer-all / use?) the user namespace before running the afterCLJReplJackInCode.

[bpringe]

@PEZ Do you think we should change the template instead of changing Calva for this? It seems when choosing the server + client connect sequence with this template, at this line:

calva/src/connector.ts

Line 55 in 5817cb4

if (connectSequence.afterCLJReplJackInCode) {

the outputWindow ns is shadow.user, but start is defined in user, hence the error. I'm not sure if Calva should modify what ns the client has after connection, so it might be wise to change the template as @tjb pointed out.

This was an issue in the template and has been fixed. luminus-framework/luminus-template#520
