vscode的3個配置文件說明。
VS需要為每一個文件夾做單獨配置，所以建議把.vscode文件夾放到你常用的文件夾的頂層，這樣就不用重復配置了。
不用每個新cpp文件就要一套配置。這些配置在你配置好的文件夾內的所有子文件夾和文件都能使用。
-
task.json
task.json文件告訴VS Code如何構建(編譯)程序。這個任務將調用g++編譯器來創建一個基於源代碼的可執行文件。
Terminal > Configure Default Build Task.
{
"version": "2.0.0",
"command": "g++", // label，可任取
"args": [ // g++命令行參數
"-g",
"${workspaceFolder}\\*.cpp",
"-I",
"--std=c++11",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"

"file": 1,

}
}
}
-
launch.json
launch.json文件配置VS Code啟動GDB調試器。
通過智能提示查看有那些屬性可以設置, 如果要查看屬性的具體含義, 可以把鼠標懸停在屬性上面, 會屬性的使用說明.
{
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch", // 配置名稱，將會在啟動配置的下拉菜單中顯示
"type": "cppdbg", // 配置類型，這里只能為cppdbg
"request": "launch", // 請求配置類型，可以為launch（啟動）或attach（附加）
"program": "${fileDirname}/${fileBasenameNoExtension}.exe", // 將要進行調試的程序的路徑
"args": [], // 程序調試時傳遞給程序的命令行參數，一般設為空即可
"stopAtEntry": false, // 設為true時程序將暫停在程序入口處，一般設置為false
"cwd": "${workspaceFolder}", // 調試程序時的工作目錄，一般為${workspaceRoot}即代碼所在目錄
"environment": [],
"externalConsole": true, // 調試時是否顯示控制台窗口，一般設置為true顯示控制台
"MIMode": "gdb",
"miDebuggerPath": "C:/Program Files/mingw-w64/x86_64-8.1.0-win32-seh-rt_v6-rev0/mingw64/bin/gdb.exe", // miDebugger的路徑，注意這里要與MinGw的路徑對應
"preLaunchTask": "g++", // 調試開始前執行的任務，要與task.json里的label/command值一樣
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": false
}
]
}
]
}

c_cpp_properties.json
c_cpp_properties.json 對C/ C++擴展進行更多控制，允許相關改變設置，例如編譯器的路徑，包括路徑，c++標准(默認是c++ 17)，等等。

{

vscode預定義的變量
e.g.: 1. vscode編輯器打開的文件：/home/your-username/your-project/folder/file.ext 2. vscode打開的根工作區：/home/your-username/your-project ${workspaceFolder} - 在VS Code中打開的文件夾路徑 - /home/your-username/your-project ${workspaceFolderBasename} - 在VS Code中打開的文件夾名稱沒有任何斜杠(/) - your-project ${file} - 當前打開的文件 - /home/your-username/your-project/folder/file.ext ${fileWorkspaceFolder} - 當前打開的文件所在的文件夾 - /home/your-username/your-project ${relativeFile} - 相對於workspaceFolder，當前打開的文件 - folder/file.ext ${relativeFileDirname} - 相對於workspaceFolder，當前打開的文件的目錄名 - folder ${fileBasename} - 當前打開的文件的基名 - file.ext ${fileBasenameNoExtension} - 當前打開的文件的基名沒有文件擴展名 - file ${fileDirname} - 當前打開文件的目錄名 - /home/your-username/your-project/folder ${fileExtname} - 當前打開的文件的擴展名 - ext ${cwd} - 任務運行器啟動時的當前工作目錄 ${lineNumber} - 活動文件中當前選定的行號 ${selectedText} - 活動文件中當前選定的文本 ${execPath} - 運行VS Code可執行文件的路徑 ${defaultBuildTask} - 默認生成任務的名稱 ${pathSeparator} - 操作系統用於分隔文件路徑中的組件的字符 - / on macOS or linux, \\ on Windows
