Visual Studio Code Tutorial (WSL/windows + mingw)

設定 VSCode 環境 (WSL)

NOTE: 安裝教學影片 WSL Tutorial

安裝 WSL & GCC

Install WSL: https://docs.microsoft.com/en-us/windows/wsl/install

啟動 WSL Ubuntu

start ubuntu

在 WSL Ubuntu 輸入以下指令：

sudo apt update
sudo apt install -y build-essential g++ gdb
g++ -v

Wrong:

g++ wrong

Correct:

g++ correct

安裝 VSCode & Remote - WSL plugin

Install VSCode: https://code.visualstudio.com/docs/setup/windows

Install the Remote - WSL extension for VSCode: https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-wsl

新增專案 (Hello world!)

重新打開 WSL Ubuntu 並輸入以下指令：

$ mkdir projects
$ cd projects
$ code .

Correct:

wsl correct 2

安裝 WSL C++ plugin

Install the C++ extension for VSCode: https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools

Correct:

c++ in wsl

In VSCode: Exploer -> New File

輸入 test.cpp

new file icon

在文字輸入區輸入以下程式碼

#include <iostream>
#include <vector>
#include <string>

using namespace std;

int main()
{
    vector<string> msg {"Hello", "C++", "World", "from", "VS Code", "and the C++ extension!"};

    for (const string& word : msg)
    {
        cout << word << " ";
    }
    cout << endl;
}

input cpp code

編譯 & 執行 Hello world!

In VSCode: Terminal -> New Terminal

create terminal

In VSCode Terminal:

$ g++ test.cpp
$ ./a.out
Hello C++ World from VS Code and the C++ extension! 
$

Debugger

可以設置中斷點，方便程式除錯。

`launch.json`

In VSCode: Exploer -> New Folder

輸入 .vscode

new folder icon

In VSCode: Exploer -> New File

輸入 launch.json

在文字輸入區輸入以下設定檔

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/a.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

編譯 & 執行 Debugger

In VSCode Terminal:

$ g++ -g test.cpp
$

插入中斷點

在要中斷的程式碼行號左邊點一下

insert breakpoint

In VSCode: Run -> Start Debugging F5

start debugging

run gdb

安裝步驟

下載vscode-all-in-one.zip
解壓縮縮後，將檔案放到路徑%USERPROFILE%
將%USERPROFILE%\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin加入到環境變數Path
完成

圖解說明

%USERPROFILE% 是windows的環境變數，指的是該電腦使用者的目錄。概念同linux底下的${HOME}。以本台測試電腦為例，該電腦使用者為WDAGUtilityAccount，則%USERPROFILE%=C:\Users\WDAGUtilityAccount。正常請況下在檔案總管上的路徑列輸入%USERPROFILE%後會自動跳轉。如下圖示範：

windows_var
