Answer edited: How can I make Calva use a relative path when loading a file in cljs?

Hello. I don't think there is a way to configure that currently. You are welcome to file an issue about it. We can probably make this work.

Meanwhile.

Is shadow-cljs or Figwheel managing the loading of the project? If so, saving the file should load it .

Also, I think you most often get away with selecting the whole file and evaluate selection. You can configure a keyboard shortcut like this to give yourself something quite similar to the command that doesn't work:

  {
    "command": "runCommands",
    "key": "ctrl+alt+c ctrl+alt+enter",
    "args": {
      "commands": [
        "editor.action.selectAll",
        "calva.evaluateSelection",
        "cursorUndo"
      ]
    }
  },

You can add a when clause to it to only operate on cljs files. I think it would be resourceExtName == .cljs. See https://code.visualstudio.com/api/references/when-clause-contexts

That said, it's probably fine to let it load Clojure files this way as well. You can copy the existing when clause from the command in the in Keyboard Shortcuts UI.

Commented: Refresh/Reload deps.edn changes in Calva + VS Code in WSL Ubuntu

There is no command in Calva for reloading the project. With Clojure 1.12, add-libs can be used for loading a library into the project dynamically. Generally it is what you tried to do, restarting the REPL. But of course, the project files need to be fine . I see that you found the issue there.

Calva has a command Calva: Replace Current Form (or Selection) with Pretty Printed Form that does this. Your pretty printer settings need to have a narrow print width.

Calva does not have configuration designed for setting Java options. That doesn't mean you don't have options, though. First some general background:

You can provide these via :jvm-opts on an alias in deps.edn, or via the environment variable JAVA_TOOL_OPTIONS. Something like this would be an equivalent command line invokation (assuming something Unix-like):

JAVA_TOOL_OPTIONS='-Dtrace -Dguardrails.enabled=true' clj -A:dev

You then can use the command Calva: Copy Jack-in Command Line to Clipboard, to get the REPL started in a Calva compliant way, then use Calva: Connect to a Running REPL in your Project, to connect to it.

However, you can also use Jack-in. Calva has a settings calva.jackInEnv, where you can provide this environment variable, and Jack-in should work.

Yet another, Jack-in compatible, option is to add this in your deps.edn. Something like:

:aliases {:dev {:jvm-opts ["-Dtrace" "-Dguardrails.enabled=true"]}}

You could then specify the :dev alias at Calva Jack-in.

I think I would go with the last one, as it makes the project config portable and easy for others to use.

Hoping this helps! Here is an article about Calva Jack-in that probably is good to read.

Recategorized: Calva: Is there a way to evaluate a whole file?

Beside selecting the whole file and then evaluating the selection, can I evaluate the whole file in a more convenient way?
