serverReadyAction doesn't work when output is sent to the debug console (ie useTerminal is false)

[rockorequin]

In version 0.1.0, output is sent by default to the debug console (it used to only go to a new terminal, but now you can choose where it goes via the useTerminal setting).

I'm running a Rails server and the serverReadyAction doesn't execute when output goes to the debug console. However, if I specify "useTerminal": true in launch.json, serverReadyAction works, ie the webpage http://localhost:3000 opens in a browser window.

My launch.json configuration is:

      "name": "rdbg",
      "type": "rdbg",
      "request": "launch",
      "script": "${workspaceRoot}/bin/rails",
      "cwd": "${workspaceRoot}",
      "args": [
        "server"
      ],
      "serverReadyAction": {
        "pattern": "Listening on http://127.0.0.1:([0-9]+)",
        "uriFormat": "http://localhost:%s",
        "action": "openExternally"
      }

what is "serverReadyAction"?

[rockorequin]

serverReadyAction instructs VSCode to scan the log for a pattern and then take an action once it's seen (openExternally tells it to open the uriFormat string in a browser). See https://code.visualstudio.com/docs/editor/debugging#_automatically-open-a-uri-when-debugging-a-server-program.

Thank you for the information. This is first time to see.

Do you know other debuggers (on other languages) support it on the debug console?

[rockorequin]

Excellent question! I'm not sure about other languages, but serverReadyAction works with output going to the debug console in the "Ruby" extension by Peng Lv (I think it's this one: https://marketplace.visualstudio.com/items?itemName=rebornix.Ruby). It uses the ruby-debug-ide and debase gems.

I just ran it to confirm that a new browser window opens once the Rails server writes "* Listening on http://127.0.0.1:3000" to the debug console. My launch.json contains:

    {
      "name": "rdebug-ide",
      "type": "Ruby",
      "request": "launch",
      "program": "${workspaceRoot}/bin/rails",
      "cwd": "${workspaceRoot}",
      "args": [
        "server"
      ],
      "serverReadyAction": {
        "pattern": "listening on http://127.0.0.1:([0-9]+)",
        "uriFormat": "http://localhost:%s",
        "action": "openExternally"
      }
    },

Thank you so there is a way to support it on the debug console...
