Mac使用vimspector调试c++


vimspector安装

vim配置文件加入一下内容

1
2
Plug 'puremourning/vimspector'
let g:vimspector_enable_mappings = 'HUMAN'

:PlugInstall安装插件即可。

上面的HUMAN是插件配置的一套快捷命令。具体如下

Key Function API
F5 When debugging, continue. Otherwise start debugging. vimspector#Continue()
F3 Stop debugging. vimspector#Stop()
F4 Restart debugging with the same configuration. vimspector#Restart()
F6 Pause debugee. vimspector#Pause()
F9 Toggle line breakpoint on the current line. vimspector#ToggleBreakpoint()
F9 Toggle conditional line breakpoint on the current line. vimspector#ToggleBreakpoint( { trigger expr, hit count expr } )
F8 Add a function breakpoint for the expression under cursor vimspector#AddFunctionBreakpoint('')
F10 Step Over vimspector#StepOver()
F11 Step Into vimspector#StepInto()
F12 Step out of current function scope vimspector#StepOut()

在vimspector目录运行 以上按照你本所需调试语言的命令即可。这里我只需调试C++代码。在我本地~/.vim/plugged/vimspector/下执行

1
./install.py --enable-c

这里会去下载一个cpptools-osx.vsix文件 可以挂vpn运行安装。或者下好放到对应的文件加即可。

在~/.vim/plugged/vimspector/gadgets/macos下添加.gadgets.json文件

            "${gadgetDir}/vscode-cpptools/debugAdapters/OpenDebugAD7"
        ],
        "name": "cppdbg"
        }
    }
}

新建文件夹~/.vim/plugged/vimspector/gadgets/macos/.gadgets.d 添加lldb-vscode.json文件

}

项目配置

在项目下添加.vimspector.json

        "MIMode": "lldb",
        "logging": {

      }
    }
  }
}

其中program是本地的项目编译后的文件。这的mac下需要使用clang进行编译，使用gcc无法调试。

编辑a.cpp文件

#include<stdio.h>
int main(){
    int a = 1;
    int b = 2;
    int c = a + b;
    printf("%d", c);
    return 0;
}

vim打开a.cpp文件 F9添加断点 F5进入调试。结果如下图所示

F11逐步调试即可。
