最近開始使用Vs codel,真的方便,能夠和git結合。下面總結一下如何調試程序,ios
我寫了一個實例程序(不重要)git
#include <iostream> #include <fstream> #include <string> #include <vector> #include <algorithm> using namespace std; int main(void) { fstream iofile("test.txt"); vector<string> strs(20); int i=0; if(!iofile){ cerr<<"open file failed"<<endl; }else{ while(iofile>>strs[i++]); } for(int j=0;j<i-1;j++) { cout<<strs[j]<<endl; } // cout<<endl; cout<<"after sort"<<endl; cout<<*(strs.begin())<<endl; sort(strs.begin(),strs.begin()+i-1); cout<<"i:"<<i<<" "<<strs[1]<<endl; for(int j=0;j<i;j++) { cout<<strs[j]<<" "; } cout<<endl; return 0; }
這個時候,咱們按F5,發現不能運行,它提示須要一個Launch.json文件,OK,這是一個啓動文件,咱們來配置它。shell
{ // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "(gdb) Launch", "type": "cppdbg", "request": "launch", "program": "${workspaceFolder}/build", "preLaunchTask": "build", "args": [], "stopAtEntry": false, "cwd": "${workspaceFolder}", "environment": [], "externalConsole": true, "MIMode": "gdb", "setupCommands": [ { "description": "Enable pretty-printing for gdb", "text": "-enable-pretty-printing", "ignoreFailures": true } ] } ] }
注意,這裏須要修改的部分主要是program那一行,僅需修改成本身編譯後產生的文件名,不如g++ -g 1.7.cpp -o build,因此這裏我就取了build這個名字。json
還有,就是要添加preLaunchTask這一行,名字與下面的task要對應。ui
這裏,它還須要一個task.json文件,配置以下,spa
{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "build", "type": "shell", "command": "g++", "args": [ "-g", "${workspaceFolder}/chapter01/1.7.cpp", "-o", "build" ] } ] }
你們能夠看到,這裏只須要將label的值要與上面的preLaunchTask相對應,其餘的就是命令行部分,完成這個文件後,咱們ctrl+shift+b,這是會執行task。命令行
以後,咱們打開main文件,設置斷點,F5便可開始調試代碼。debug
關於Launch.json:調試
官方是這樣說的:However, for most debugging scenarios, creating a launch configuration file is beneficial because it allows you to configure and save debugging setup details. VS Code keeps debugging configuration information in a launch.json file located in a .vscode folder in your workspace (project root folder) or in your user settings or workspace settings.可是,對於大多數調試方案,建立啓動配置文件是有益的,由於它容許您配置和保存調試設置詳細信息。 VS Code將配置信息保存在位於工做區(項目根文件夾)的.vscode文件夾或用戶設置或工做區設置中的launch.json文件中。code
我的感受多是項目比較簡單因此看不來它的好處。
