用于xmake-vscode 在windows下debug Qt application的launch.json文件分享

[whhxp]

launch.json

{
    "configurations": [
        {
            "name": "qt5natvis_launcher",
            "type": "cppdbg",
            "request": "launch",
            "visualizerFile": "${workspaceFolder}/.vscode/qt5.natvis.xml",
            "showDisplayString": true,
            "program": "${workspaceFolder}/build/mingw/x86_64/debug/qtWidgetTest.exe",
            "args": [],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false,
            "windows": {
                "environment": [
                    {
                        "name": "Path",
                        "value": "D:/Qt/Tools/mingw810_64/bin;D:/Qt/5.15.2/mingw81_64/lib;D:/Qt/5.15.2/mingw81_64/bin"
                    }
                ],
                "externalConsole": false,
                "MIMode": "gdb",
                "miDebuggerPath": "D:/Qt/Tools/mingw810_64/bin/gdb.exe",
            },
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                },
                {
                    "description": "Fix pretty-printing for gdb",
                    "text": "set charset UTF-8"
                }
            ]
        },
    ]
}

有两个问题

• 问题1： 在windows平台，vscode debug中正确显示qt的数据结构

  解决方案：
  
  一开始找资料时发现需要qt的visualizeFile，例如qt5.natvis或者qt6.natvis文件，在github中找了一个，参考链接为：
  https://github.com/qt-labs/vstools/blob/dev/QtVsTools.Package/qt5.natvis.xml
  https://github.com/qt-labs/vstools/blob/dev/QtVsTools.Package/qt6.natvis.xml
  

• 问题2： debug的时候显示u<error reading variable>

  解决方案：
  
  Because pretty-printer is not displaying utf-8 char correctly. To display utf-8 char, edit the setupCommands in launch.json。
