VSCode，定义在任务中使用的自定义变量，lauch和cpp属性

Question

我正在为使用北欧NRF52的嵌入式开发设置VSCode。我注意到在nrf_sdk中有几个板和几个软设备的例子。我已经看到可以引用之前在tasks，launch和extension属性中定义的环境变量，例如: c_cpp，stm32-for-vscode。但是，如果在工作区文件中定义一个节为my_vars，那么工作区文件看起来像这样呢？

{
"my_vars": {
    "BOARD_NAME": "NRF52840_MDK_USB_DONGLE",
    "MCU_NAME": "NRF52840",
    "SOFT_DEVICE": "S140",
    "BOARD_VARIANT_PATH": "/pca10059/mbr"

},
"launch": {

    {

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

            },
            },
            {
            "label": "nRF52 sdk_config",
            "type": "shell",
            "command": "make sdk_config",
            "options": {

            },
            "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，在我的例子中，因为我在Windows中，所以运行一个批处理脚本，它执行以下操作：

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

这将大大简化开发工具包示例，并可能成为NRF52 VSCode扩展的潜在工作，就像https://marketplace.visualstudio.com/items?itemName=bmd.stm32-for-vscode一样。

Answer 1

请看一下扩展Command Variable。

它可以使用文件的内容作为key-value pairs。
