Usages

• To run code:
  • use shortcut Ctrl+Alt+N
  • or press F1 and then select/type Run Code,
  • or right click the Text Editor and then click Run Code in editor context menu

• To run custom command, then use shortcut Ctrl+Alt+K, or press F1 and then select/type Run Custom Command

Configuration

Make sure the executor PATH of each language is set in the environment variable. You could also add entry into code-runner.executorMap to set the executor PATH. e.g. To set the executor PATH for ruby, php and html:

{
    "code-runner.executorMap": {
        "javascript": "node",
        "php": "C:\\php\\php.exe",
        "python": "python",
        "perl": "perl",
        "ruby": "C:\\Ruby23-x64\\bin\\ruby.exe",
        "go": "go run",
        "html": "\"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe\"",
        "java": "cd $dir && javac $fileName && java $fileNameWithoutExt",
        "c": "cd $dir && gcc $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt"
    }
}

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

You could set the executor per filename glob:

{
    "code-runner.executorMapByGlob": {
        "pom.xml": "cd $dir && mvn clean package",
        "*.test.js": "tap",
        "*.js": "node"
    }
}

Besides, you could set the default language to run:

{
    "code-runner.defaultLanguage": "javascript"
}

For the default language: It should be set with language id defined in VS Code. The languages you could set are java, c, cpp, javascript, php, python, perl, ruby, go, lua, groovy, powershell, bat, shellscript, fsharp, csharp, vbscript, typescript, coffeescript, swift, r, clojure, haxe, objective-c, rust, racket, ahk, autoit, kotlin, dart, pascal, haskell, nim, d, lisp

Also, you could set the executor per file extension:

{
    "code-runner.executorMapByFileExtension": {
        ".vbs": "cscript //Nologo"
    }
}

To set the custom command to run:

{
    "code-runner.customCommand": "echo Hello"
}

To set the the working directory:

{
    "code-runner.cwd": "path/to/working/directory"
}

To set whether to clear previous output before each run (default is false):

{
    "code-runner.clearPreviousOutput": false
}

To set whether to save all files before running (default is false):

{
    "code-runner.saveAllFilesBeforeRun": false
}

To set whether to save the current file before running (default is false):

{
    "code-runner.saveFileBeforeRun": false
}

To set whether to show extra execution message like [Running] ... and [Done] ... (default is true):

{
    "code-runner.showExecutionMessage": true
}

[REPL support] To set whether to run code in Integrated Terminal (only support to run whole file in Integrated Terminal, neither untitled file nor code snippet) (default is false):

{
    "code-runner.runInTerminal": false
}

To set whether to preserve focus on code editor after code run is triggered (default is true, the code editor will keep focus; when it is false, Terminal or Output Channel will take focus):

{
    "code-runner.preserveFocus": true

About CWD Setting (current working directory)

1. By default, use the code-runner.cwd setting
2. If code-runner.cwd is not set and code-runner.fileDirectoryAsCwd is true, use the directory of the file to be executed
3. If code-runner.cwd is not set and code-runner.fileDirectoryAsCwd is false, use the path of root folder that is open in VS Code
4. If no folder is open, use the os temp folder

• For Objective-C, it is only supported on macOS
• To run C# script, you need to install scriptcs
