在Visual Studio Code中，使用launch.json中的“input”选择来用于preLaunchTask。

Question

在项目中有许多辅助工具。在启动和任务的json文件中，它们被配置为允许用户选择要构建或调试的特定工具。我想做的是让来自启动的选择传递到任务，并让任务使用该选择。launch.json配置文件如下所示：

launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug: <Utility App>",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/apps/${input:utility}/${input:utility}",
            "args": ["--notimeout", "--pit"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}/apps/${input:utility}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "preLaunchTask": "make utility",
        },
    "inputs": [
        {
          "type": "pickString",
          "id": "utility",
          "description": "Which utility app do you want to run?",
          "options": [
            "utility_1",
            "utility_2",
            "utility_3",
            "utility_4",
          ]
        },
    ]
}

tasks.json配置文件的格式如下：

tasks.json
{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "make utility",
            "type": "process",
            "command": "make",
            "args": [ "${input:BuildUtility}" ],
            "group": "build",
            "problemMatcher": "$gcc"
        },
    ],
    "inputs": [
        {
            "type": "pickString",
            "id": "BuildUtility",
            "description": "Which utility do you want to build?",
            "options": [
                "utility_1",
                "utility_2",
                "utility_3",
                "utility_4",
            ]
        }
    ]
}

我该如何通过从launch中选择的preLaunchTask来传递选择，从而有效地覆盖"${input:BuildUtility}"，以便用户不需要为"args"字段做出选择？如果没有向任务传递任何内容，任务仍会要求进行选择。谢谢。

在撰写本文时，似乎还不支持此功能。已提出请求以添加此功能。现在只需要等待并观察社区是否会投票赞同足够多的人来添加它。 - lordhog

我为此进行了很多搜索，最终来到了这里。根据@lordhog提到的功能请求，我猜测是指这个链接：https://github.com/microsoft/vscode/issues/95158 不幸的是，由于缺乏赞同票数，该请求已被关闭。所以看起来仍然不可能实现。 - danielorn

现在，通过新的pickString输入类型，Visual Studio Code已经支持此功能。

文档中的参考链接：

pickString: 显示一个快速选择下拉菜单，让用户从几个选项中选择。

这里是一个创建选择输入的示例：

{
  "inputs": [
    {
      "type": "pickString",
      "id": "myString",
      "description": "Pick an option:",
      "options": [
        "foo",
        "bar",
        "baz"
      ],
      "default": "foo"
    }
  ]
}
