我正在使用 Nordic NRF52 为嵌入式开发设置 VSCode。我注意到在 nrf_sdk 中有几个板和几个软设备的示例。我已经看到可以引用先前在任务、启动和扩展属性中定义的环境变量，例如：c_cpp、stm32-for-vscode。但是在工作区文件中有一个部分定义为 my_vars 以使工作区文件看起来像这样呢？

{
"my_vars": {
    "BOARD_NAME": "NRF52840_MDK_USB_DONGLE",
    "MCU_NAME": "NRF52840",

    "BOARD_VARIANT_PATH": "/pca10059/mbr"

},

    {

            "problemMatcher": [],

            {
            "label": "nRF52 sdk_config",
            "type": "shell",
            "command": "make sdk_config",
            "options": {
                "cwd": "${workspaceFolder}${my_vars:BOARD_VARIANT_PATH}/armgcc"
            },
            "problemMatcher": []
            },
            {
            "label": "nRF52 erase",
            "type": "shell",
            "command": "make erase",
            "options": {
                "cwd": "${workspaceFolder}${my_vars:BOARD_VARIANT_PATH}/armgcc"
            },
            "problemMatcher": [],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            }
        ]
}
}

我尝试了一个 set_env 任务，在我的情况下，因为我在 Windows 中，所以运行一个批处理脚本：

set BOARD_NAME=NRF52840_MDK_USB_DONGLE
set MCU_NAME=NRF52840
set SOFT_DEVICE=S140
set BOARD_VARIANT_PATH=/pca10059/mbr

这将大大简化 SDK 示例的使用，并且可能是 NRF52 VSCode 扩展的潜在工作，如https://marketplace.visualstudio.com/items?itemName=bmd.stm32-for-vscode所做的那样。

看看扩展命令变量。

它可以将文件的内容用作键值对。
