如何使用 launch.json 定位平台

Question

omnisharp ReadMe 是这样说的：

Operating System Specific Configurations

If there specific commands that need to be changed per operating system, you can use the fields: 'windows', 'osx', or 'linux'. You can replace any of the fields mentioned above for the specific operating system.

这是我的 launch.json 文件：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch (console)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceFolder}/TestConsole/bin/Debug/netcoreapp2.1/TestConsole.dll",
            "args": [
                "c:\git\core\XunitTestLib\Steps\",
                // "~/../../XunitTestLib/Steps"
            ],
            "cwd": "${workspaceFolder}/TestConsole",
            "console": "internalConsole",
            "stopAtEntry": false,
            "internalConsoleOptions": "openOnSessionStart"
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach",
            "processId": "${command:pickProcess}"
        },
    ]
}

调试时我想在 Windows 上构建以从未注释的 "args" 条目开始，但是在 mac os 上我希望它从被注释掉的行。

我假设我会复制配置，一次用于 Windows 和 mac，但是这个陈述令人困惑：

You can replace any of the fields mentioned above for the specific operating system.

似乎是说我可以用 "osx" 替换 "args" 但这显然行不通。

如何为目标平台创建配置？

Answer 1

事实证明，针对多个平台比我预期的要容易得多，并且 explained here 关于 tasks.json 文件（但对 launch.json 的工作原理相同）。

我的 launch.json 文件针对 osx 和 windows 调整后如下所示：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch (console)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceFolder}/TestConsole/bin/Debug/netcoreapp2.1/TestConsole.dll",
            "windows": {
                "args": [
                    "c:\git\core\XunitTestLib\Steps\"
                ]
            },
            "osx": {
                "args": [
                    "~/../../XunitTestLib/Steps"
                ]
            },
            "cwd": "${workspaceFolder}/TestConsole",
            "console": "internalConsole",
            "stopAtEntry": false,
            "internalConsoleOptions": "openOnSessionStart"
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach",
            "processId": "${command:pickProcess}"
        },
    ]
}
