为 JsonCpp 寻找 Visual Studio 可视化工具（natvis）

Posted 2023-02-22

【中文标题】为 JsonCpp 寻找 Visual Studio 可视化工具（natvis）

【英文标题】：Looking for a visual studio visualizer (natvis) for JsonCpp

【发布时间】：2015-02-11 14:38:50

【问题描述】：

我正在寻找JsonCpp 的natvis 文件，但我找不到任何文件。

有人知道这样的文件吗？

【参考方案1】：

编辑：我已将此文件添加到visualstudio-debugger repository on GitHub。

Edit2： 此问题的另外两个答案已链接到其他 github 存储库（我尚未签出）。出于某种原因，它们被管理员删除了（我不知道为什么），所以它们在这里：

由于没有人给出答案（有些人认为由于某种原因这在 *** 上是题外话）我自己写了，就在这里。使用风险自负。
