Mac使用vimspector调试c++

vimspector安装

vim配置文件加入一下内容

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()
<leader>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('<cexpr>')
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

./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

{
    "adapters": {
        "vscode-cpptools": {
            "attach": {
                "pidProperty": "processId",
                "pidSelect": "ask"
            },
        "command": [
            "${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

{
    "adapters": {
        "lldb-vscode": {
            "variables": {
                "LLVM": {
                    "shell": "brew --prefix llvm"
                }
            },
        "attach": {
            "pidProperty": "pid",
            "pidSelect": "ask"
        },
        "command": [
            "${LLVM}/bin/lldb-vscode"
        ],
        "env": {
            "LLDB_LAUNCH_FLAG_LAUNCH_IN_TTY":
            "YES"
        },
        "name":"lldb"
        }
    }
}

项目配置

在项目下添加.vimspector.json

{
  "configurations": {
    "cpp:launch": {
      "adapter": "vscode-cpptools",
      "configuration": {
        "name": "cpp",
        "type": "cppdbg",
        "request": "launch",
        "program": "${fileDirname}/a.out",
        "args": ["*${ProgramArgs}"],
        "cwd": "${workspaceRoot}",
        "environment": [],
        "externalConsole": false,
        "stopAtEntry": true,
        "MIMode": "lldb",
        "logging": {
          "engineLogging": true
        }
      }
    }
  }
}

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。
