如何显示 VS Code 的预定义变量(例如“${workspaceFolder}"或“${fileWorkspaceFolder}")的当前值? [英] How to display current values of VS Code's predefined variables (such as "${workspaceFolder}" or "${fileWorkspaceFolder}")?

问题描述

我在尝试调试一些有角度的打字稿源代码时遇到了 VS 代码调试器的问题，我认为原因是其中一些 VS Code 变量 有错误的值 - 如此处的建议.

我想遵循该建议，但我看不到如何查询 VS 代码变量(例如，显示我的项目的这些变量的当前值).

这些变量之一是

<块引用>

${workspaceFolder}

它们用于 VS 代码的配置文件中，例如在 launch.json 文件中.

你知道有没有办法显示这些值?例如，记录这些值或在警报窗口中显示它们就足以让我进行故障排除.

解决方案

旧答案:

可能有更好的方法，但您可以运行

//"preLaunchTask": "Echo vars";在您的调试启动中，例如:{名称":Chrome : Launch with sourcemaps",类型":铬"，请求":启动"，url":http://localhost:3000"，webRoot":${workspaceRoot}"，sourceMaps":真，运行时参数":[--remote-debugging-port=9222"],preLaunchTask":Echo vars"},

在您的启动任务中，然后在 tasks.json 添加:

<代码>{标签":回声变量"，命令":回声"，参数":[${env:USERNAME}"，workspaceFolder = ${workspaceFolder}"],类型":外壳"},

这些值将被回显到终端.

编辑:

因为更高版本的 vscode 现在支持向终端发送变量，这个更简单的键绑定将在终端中打印出值:

<预><代码>[{键":alt+q"，命令":workbench.action.terminal.sendSequence"，参数":{//"text": "echo ${env:USERNAME}",//这有效文本":echo file = '${file}':workspaceFolder = '${workspaceFolder}'\u000D"}}]

然后 Alt-q 打印出值.

最后的 \u000D 只是一个返回.

I am facing an issue with VS code debugger while trying to debug some angular typescript source code, and I think the reason is that some of those VS Code Variables have the wrong value - as suggested here.

I'd like to follow that advice, but I see no way how to query the VS code variables (e.g. display the current values of these variables for my project).

One of these variables is

${workspaceFolder}

They are used in VS code's config files, for this example in the launch.json file.

Do you know if there is a way to display those values? For example, log the values or show them in an alert window would just be sufficient for me to troubleshoot it.

解决方案

Old answer:

There may be a better way but you could run a

//  "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"
},

in your launch task and then in tasks.json add:

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

Those values will be echoed to the terminal.

EDIT:

Because a later version of vscode now supports sending variables to the terminal this simpler keybinding will print out values in the terminal:

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

then Alt-q prints out the values.

The \u000D at the end is just a return.
