Where can I find settings-variable-reference visual studio code documentation ? (e.g : $fileName, $fileNameWithoutExt)

Question

I'm using the Code Runner extension in vs code,

I want to change the output directory of compiled-cpp (.exe) files but I don't know what variable-name I will type in

my "settings.json" file :

"code-runner.executorMap": {
    
        "javascript": "node",
        "java": "cd $dir && javac $fileName && java $fileNameWithoutExt",
        "c": "cd $dir && gcc $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
        "cpp": "cd $dir && g++ $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt", // <- this

Is anyone know where the variable-name documentation for this case ? anyway sorry for my bad english

I've tried to implement from https://code.visualstudio.com/docs/editor/variables-reference like this :

"cpp": "cd $dir && g++ $file -o $workspaceFolder\\C++\\bin\\$fileNameWithoutExt && $workspaceFolder\\C++\\bin\\$fileNameWithoutExt",

and I got : Unexpected token '\C++\bin\stringComparison' in expression or statement

formulahendry/vscode-code-runner: Code Runner for Visual Studio Code (github.com)

Supported customized parameters

$workspaceRoot: The path of the folder opened in VS Code

$dir: The directory of the code file being run

$dirWithoutTrailingSlash: The directory of the code file being run without a trailing slash

$fullFileName: The full name of the code file being run

$fileName: The base name of the code file being run, that is the file without the directory

$fileNameWithoutExt: The base name of the code file being run without its extension

$driveLetter: The drive letter of the code file being run (Windows only)

$pythonPath: The path of Python interpreter (set by Python: Select Interpreter command)

Please take care of the back slash and the space in file path of the executor

Back slash: please use \\

If there ares spaces in file path, please use \" to surround your file path

Open Visual Studio Code -> Setting -> Upper right corner -> Press open setting.json and then edit the code runner executorMap "cpp" with this command.

"code-runner.executorMap": {
        "cpp": "cd $dir && g++ -std=c++17 \"$fileName\" -o \"$fileNameWithoutExt.o\" && $dir\"$fileNameWithoutExt.o\"",
}

Let's say your path is - /home/your-username/your-project/folder/file.cpp Now you make a "build" directory in which you can output your compiled files with path - /home/your-username/your-project/folder/build

So you change your setting.json to this

OLD: "cpp": "cd $dir && g++ $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",

NEW: "cpp": "cd $dir && g++ $fileName -o $dir/build/$fileNameWithoutExt && $dir/build/$fileNameWithoutExt",
