Is there an online name demangler for C++?
提问by Roman Starkov
I'm getting a fairly long and confusing link error, and would love it if I could just paste it into some textbox on some website and have the names un-mangled for me.
我收到了一个相当长且令人困惑的链接错误，如果我可以将它粘贴到某个网站上的某个文本框中并为我取消名称，我会很高兴的。
Does anyone know of such a service?
有人知道有这样的服务吗？

I have created such an online serivice: https://demangler.com
我创建了这样一个在线服务： https://demangler.com
This is a gcc c++ symbol demangler. You just copy a stack trace, or the output of nm into a text box, and it will return the output with the names demangled.
这是一个 gcc c++ 符号 demangler。您只需将堆栈跟踪或 nm 的输出复制到文本框中，它就会返回名称已取消的输出。
@Update: It now demangles MSVC and Java symbols also.
@Update：它现在也对 MSVC 和 Java 符号进行了解码。

This might be a bit late, but I created one, based on this question. It works with the inputs I tried on, supports g++ and msvc++ via __cxa_demangle and __unDName, compiled to Javascript via Emscripten. Hope this helps someone: c++filtjs
这可能有点晚了，但我根据这个问题创建了一个。它适用于我尝试过的输入，通过 __cxa_demangle 和 __unDName 支持 g++ 和 msvc++，通过 Emscripten 编译为 Javascript。希望这对某人有所帮助：c++filtjs
Edit: Fixed escaping problem
编辑：固定转义问题

Most (if not all) C++ compilers come with c++filttool which does precisely what you apparently looking for.
大多数（如果不是全部）C++ 编译器都带有c++filt工具，它可以准确地完成您显然在寻找的内容。
If you want it at the mouse click... well write a GUI for it ;)
如果你想通过鼠标点击它......为它编写一个 GUI ;)

There are two copy-and-paste online solutions:
有两种复制粘贴在线解决方案：
- demangler.com, which supports GCC, Visual Studio, or Java symbols
- c++filtjs, which supports GCC and Visual Studio but has problems with template parameters
- demangler.com，支持 GCC、Visual Studio 或 Java 符号
- c++filtjs，支持 GCC 和 Visual Studio 但模板参数有问题
If you only need support for GCC and Clang, you also have the option of using Coliru, which is probably the most versatile online C++ compiler.
如果您只需要支持 GCC 和 Clang，您还可以选择使用Coliru，它可能是最通用的在线 C++ 编译器。
This is not quite as simple as cut, paste, and click - but not too much harder - and it looks like there are no issues with template parameters as was noted above. You just need to modify the command line to run something like this:
这并不像剪切、粘贴和单击那么简单——但也不会太难——而且看起来模板参数没有上面提到的问题。你只需要修改命令行来运行这样的东西：
cat main.cpp | c++filt -t
See it live with this examplewhich demangles:
_Z6kernelIfLj3EEvPT_5arrayIPKS0_XT0_EES5_S2_IjXT0_EES6_S0_
to:
到：
void kernel<float, 3u>(float*, array<float const*, 3u>, array<float const*, 3u>, array<unsigned int, 3u>, array<unsigned int, 3u>, float)
^^^^^^^^^^^
