如何将输入变量从launch.json传递到vscode中的tasks.json答案

【问题标题】：How to pass input variable from launch.json to tasks.json in vscode如何将输入变量从launch.json传递到vscode中的tasks.json

【问题描述】：

我可以在launch.json 中使用来自launch.json 的输入变量。

"configurations": [
  {
    ...
    "args": [${input:file_no}]
    "preLanuchTask": "runPreTasks"
    ...
  }
],
"inputs": [
  {
    "id": "file_no",
    "type": "promptString"
  }
]

现在，我想访问同一个变量，而无需在tasks.json 中再次输入。

{
  "version": "2.0.0",
  "tasks":[
    {
      "label": "runPreTasks",
      "type": "shell",
      "command": sh,
      "args": [
        "/path2script/scriptName.sh",
        "${input:file_no}"    // This does not work, without defining input again
      ]
    }
  ]
}

有没有办法在 vscode 中将输入变量从launch.json 传递到tasks.json？

【解决方案1】：

您可以使用扩展名Command Variable v1.21.0

它有一个命令extension.commandvariable.promptStringRemember，其行为与${input:name} promptString 变量相同。通过添加key 属性，结果将保存在此键下，您可以使用extension.commandvariable.rememberPick 命令检索它。

extension.commandvariable.rememberPick 命令可用于与extension.commandvariable.promptStringRemember 命令不同的任务/启动

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Task 1",
      "type": "shell",
      "command": "dostuff1",
      "args": ["-p", "${input:promptPath}"]
    },
    {
      "label": "Task 2",
      "type": "shell",
      "command": "dostuff2",
      "args": ["-p", "${input:rememberPath}"]
    },
    {
      "label": "Do Task 1 and 2",
      "dependsOrder": "sequence",
      "dependsOn": ["Task 1", "Task 2"],
      "problemMatcher": []
    }
  ],
  "inputs": [
    {
      "id": "promptPath",
      "type": "command",
      "command": "extension.commandvariable.promptStringRemember",
      "args": {
        "key": "path",
        "description": "Enter a path"
      }
    },
    {
      "id": "rememberPath",
      "type": "command",
      "command": "extension.commandvariable.rememberPick",
      "args": { "key": "path" }
    }
  ]
}

您好，感谢您的回答和扩展。您展示的示例与我的问题不匹配。我想从lauch.json 获取输入，这些输入将用于lauch.json 和tasks.json。此外，从给定的示例中，promptStringRemember 和 rememberPick 之间的区别对我来说并不清楚。与我的问题相关的示例将非常有帮助。再次感谢。

根据@rioV8 的回答，我编辑了我的json 文件，如下所示：

launch.json:

"configurations": [
  {
    ...
    "args": [${input:file_no}]
    "preLanuchTask": "runPreTasks"
    ...
  }
],
"inputs": [
  {
    "id": "file_no",
    "type": "command",
    "command": "extension.commandvariable.promptStringRemember",
    "args": {
      "key": "lastnumber",
      "description": "Enter the number"
    }
  }
]

tasks.json:

{
  "version": "2.0.0",
  "tasks":[
    {
      "label": "runPreTasks",
      "type": "shell",
      "command": sh,
      "args": [
        "/path2script/scriptName.sh",
        "${input:file_no}"    
      ]
    }
  ]
  "inputs": [
    {
      "id": "file_no",
      "type": "command",
      "command": "extension.commandvariable.rememberPick",
      "args": { "key": "lastnumber" }
    }
  ]
}
