What is the best way to show the current values of predefined variables in VS Code, like "${workspaceFolder}" or "${fileWorkspaceFolder}"?

My current challenge involves debugging some Angular TypeScript source code in VS Code, and I suspect that the issue lies in the incorrect values of certain VS Code Variables - as mentioned here.

I want to address this by checking the values of the VS Code variables (like displaying the current values for my project), but I am unsure how to proceed.

One such variable is

${workspaceFolder}

These variables are utilized in the configuration files of VS Code, such as the launch.json file.

Is there a way to access these values? Even something simple like logging or displaying them in an alert window would help me troubleshoot the issue.

Answer №1

Original Response:

One potential solution is to add the following configuration to your debug launch settings:

//  "preLaunchTask": "Echo vars" in your debug launch like:

{
    "name": "Chrome : Launch with sourcemaps",
    "type": "chrome",
    "request": "launch",
    "url": "http://localhost:3000",
    "webRoot": "${workspaceRoot}",
    "sourceMaps": true,
    "runtimeArgs": [
    "--remote-debugging-port=9222"
    ],
    "preLaunchTask": "Echo vars"
},

You can then define the "Echo vars" task in your tasks.json file as follows:

{
   "label": "Echo vars",
   "command": "echo",
   "args": [
     "${env:USERNAME}",
     "workspaceFolder = ${workspaceFolder}"
   ],
   "type": "shell"
},

These values will be displayed in the terminal.

UPDATE:

With the latest version of vscode supporting variable input in the terminal, a simpler keybinding can now be used to print out values:

[
    {
        "key":  "alt+q",
        "command": "workbench.action.terminal.sendSequence",
        "args": {
            // "text": "echo ${env:USERNAME}",  // this works
            "text" : "echo file = '${file}' : workspaceFolder = '${workspaceFolder}'\u000D"
        }
    }
]

Pressing Alt-q will now display the values in the terminal.

The \u000D at the end represents a return.

Navigate to C:\Users\your user name\AppData\Roaming\Code\User\keybindings.json

Insert the following code snippet into keybindings.json. Feel free to customize with any predefined variables.

{
    "key":  "ctrl+shift+f",
    "command": "editor.action.formatDocument",
    "when": "editorFocus"
}

Press ctrl+shift+f to automatically format the document.
