  "github_readme_excerpt": "# demumble\n\n`demumble` demangles both Itanium and Visual Studio symbols. It runs on\nboth POSIX and Windows.\n\n    $ demumble _Z4funcPci\n    func(char*, int)\n    $ demumble \u0027?Fx_i@@YAHP6AHH@Z@Z\u0027\n    int __cdecl Fx_i(int (__cdecl *)(int))\n\nIt can also demangle D, Rust, and Swift symbols.\n\n## Download\n\nThere are prebuilt x64 binaries for Linux, Mac (10.9+), and Windows on the\n[releases page](https://github.com/nico/demumble/releases).\n\n## But why\n\nIt has several nice features that c++filt lacks (and lacks many of c++filt\u0027s\nfeatures I never use).\n\nSmart about underscores: C++ symbols have an additional leading underscore on\nmacOS. `operator new` is mangled as `_Znw` on Linux but `__Znw` on Mac. macOS\u0027s\nc++filt automatically strips one leading underscore, but Linux\u0027s c++filt\ndoesn\u0027t. So if you want to demangle a Linux symbol on macOS, you need to pass\n`-n` to tell it to not strip the underscore, and if you want to demangle an OS\nX symbol on Linux you likewise need to pass `-_`. demumble just does the right\nthing:\n\n    $ c++filt _Znw\n    _Znw\n    $ c++filt __Znw\n    operator new\n    $ demumble _Znw\n    operator new\n    $ demumble __Znw\n    operator new\n\nSmart about filtering: Both c++filt and demumble can work as a stdin filter.\ndemumble only demangles function symbols (which never look like other words),\nwhile c++filt on macOS defaults to demangling type names too, which are likely\nto look like regular words. demumble does demangle types when they\u0027re passed\nas args without requiring the `--types` switch that c++filt needs on Linux:\n\n    # on macOS:\n    $ echo \u0027I like Pi and _Znw\u0027 | c++filt\n    I like int* and _Znw\n    $ echo \u0027I like Pi and _Znw\u0027 | demumble\n    I like Pi and operator new\n    $ c++filt Pi\n    int*\n    $ demumble Pi\n    int*\n    # on Linux:\n    $ c++filt Pi\n    Pi\n\nCross-platform: demumble runs on Windows. demumble can demangle Windows-style\nsymbols (also when running on non-Windows).\n\n    $ demumble \u0027??2@YAPEAX_K@Z\u0027\n    void * __cdecl operator new(unsigned ",
