Mac下 vscode c/c++ 自动编译配置，macvscode

本人mac版本10.12.5 ，vscode版本为 1.13

步骤很简单，添加好各种与c++有关的插件后，reload一次，重启vscode。

在helloworld.cpp所在文件夹下创建.vscode文件夹，在.vscode中创建2个文件：tasks.json , launch.json

接着是各个文件的内容：

tasks.json:(编译配置，也就是用cpp生成a.out的过程)

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    ”version”: ”0.1.0”,
    ”command”: ”g++”,  //command 和 args 组合为编译c++命令，即 g++ -g xxx.cpp -o a.out
    ”isShellCommand”: true,
    ”args”: [”-g”,”${file}</span></span></span><span class="hljs-string">"</span></span>,<span class="hljs-string"><span class="hljs-string">"-o"</span></span>,<span class="hljs-string"><span class="hljs-string">"a.out"</span></span>],  <span class="hljs-comment"><span class="hljs-comment">//${file}代表着任意文件名，代替了helloworld.cpp
    ”showOutput”: ”always”,
    ”problemMatcher”: {  //正则匹配，删除无用符号
        ”owner”: ”cpp”,
        ”fileLocation”: [”relative”, ”${workspaceRoot}</span></span></span><span class="hljs-string">"</span></span>],</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="12"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">        <span class="hljs-string"><span class="hljs-string">"pattern"</span></span>: {</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="13"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">            <span class="hljs-string"><span class="hljs-string">"regexp"</span></span>: <span class="hljs-string"><span class="hljs-string">"^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$”,
            ”file”: 1,
            ”line”: 2,
            ”column”: 3,
            ”severity”: 4,
            ”message”: 5
        }
    }
}

launch.json:(调试配置，也就是运行a.out的过程)

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(lldb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceRoot}</span></span></span><span class="hljs-string">/a.out"</span></span>, <span class="hljs-comment"><span class="hljs-comment">//调试，也就是运行a.out文件</span></span></div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="9"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">            <span class="hljs-string"><span class="hljs-string">"args"</span></span>: [],</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="10"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">            <span class="hljs-string"><span class="hljs-string">"stopAtEntry"</span></span>: <span class="hljs-literal"><span class="hljs-literal">false</span></span>,</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="11"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">            <span class="hljs-string"><span class="hljs-string">"cwd"</span></span>: <span class="hljs-string"><span class="hljs-string">"</span><span class="hljs-subst"><span class="hljs-string"><span class="hljs-subst">${workspaceRoot}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "lldb",
            "preLaunchTask": "g++" //代表执行launch.json前先执行tasks.json中的g++指令
        }
    ]
}

配置完之后，按f5就能对任意在工作目录下的cpp文件进行一键编译运行调试了
