    Yo Code - Extension and Customization Generator

    Build Status

    We have written a Yeoman generator to help get you started. We plan to add templates for most extension/customization types into this.

    Install the Generator

    Install Yeoman and the VS Code Extension generator:

    npm install -g yo generator-code

    Run Yo Code

    The Yeoman generator will walk you through the steps required to create your customization or extension prompting for the required information.

    To launch the generator simply type:

    yo code

    The command generator

    Generator Output

    These templates will:

    • Create a base folder structure
    • Template out a rough package.json
    • Import any assets required for your extension e.g. tmBundles or the VS Code Library
    • For Extensions: Set-up launch.json for running your extension and attaching to a process

    Command line

      yo code [<destination>] [options]
    Argument (optional):
      The destination to create the extension in, absolute or relative to the current working
      directory. Use '.' for the current folder.
      If not provided, defaults to a folder in the current working directory with the extension
      display name.
      -h,   --help                  # Print the generator's options and usage
      -i,   --insiders              # Show the insiders options for the generator
      -q,   --quick                 # Quick mode, skip all optional prompts and use defaults
      -o,   --open                  # Open the generated extension in Visual Studio Code
      -O,   --openInInsiders        # Open the generated extension in Visual Studio Code Insiders
      -t,   --extensionType         # ts, js, colortheme, language, snippets, keymap...
            --extensionId           # Id of the extension
            --extensionDescription  # Description of the extension
            --pkgManager            # 'npm', 'yarn' or 'pnpm'
            --webpack               # Bundle the extension with webpack
            --gitInit               # Initialize a git repo
    Example usages:
      yo code                       # Create an extension in a folder with the extension's name.
      yo code . -O                  # Create an extension in current folder and open with code-insiders
      yo code Hello -t=ts -q        # Create an TypeScript extension in './Hello', skip prompts, use defaults.
      yo code --insiders            # Show the insiders options for the generator

    Run Generator using Docker

    If you don't want to install nodejs or any node packages, use this method to containerize the generator.

    Go into your project directory.

    cd <project directory>

    Build the docker image from the docker file.

    docker build -t vscode-generator-code .

    Create a docker container with volumes.

    docker run -v $(pwd):/usr/src/app vscode-generator-code

    Local development

    After making necessary changes, run npm link before running yo code to test the local version.

    You can learn more about Yeoman generator development on its documentation website.
