This repository includes configuration for a development container for working with Code - OSS in an isolated local container or using [GitHub Codespaces](https://github.com/features/codespaces).
> **Tip:** The default VNC password is `vscode`. The VNC server runs on port `5901` with a web client at `6080`. For better performance, we recommend using a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/). Applications like the macOS Screen Sharing app will not perform as well.
1. Install Docker Desktop or Docker for Linux on your local machine. (See [docs](https://aka.ms/vscode-remote/containers/getting-started) for additional details.)
2.**Important**: Docker needs at least **4 Cores and 6 GB of RAM (8 GB recommended)** to run full build. If you on macOS, or using the old Hyper-V engine for Windows, update these values for Docker Desktop by right-clicking on the Docker status bar item, going to **Preferences/Settings > Resources > Advanced**.
> **Note:** The [Resource Monitor](https://marketplace.visualstudio.com/items?itemName=mutantdino.resourcemonitor) extension is included in the container so you can keep an eye on CPU/Memory in the status bar.
3. Install [Visual Studio Code Stable](https://code.visualstudio.com/) or [Insiders](https://code.visualstudio.com/insiders/) and the [Remote - Containers](https://aka.ms/vscode-remote/download/containers) extension.
> Note that the Remote - Containers extension requires the Visual Studio Code distribution of Code - OSS. See the [FAQ](https://aka.ms/vscode-remote/faq/license) for details.
> **Tip:** While you can use your local source tree instead, operations like `yarn install` can be slow on macOS or using the Hyper-V engine on Windows. We recommend the "clone repository in container" approach instead since it uses "named volume" rather than the local filesystem.
6. After the container is running, open a web browser and go to [http://localhost:6080](http://localhost:6080) or use a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/) to connect to `localhost:5901` and enter `vscode` as the password.
> **IMPORTANT:** The current free user beta for GitHub Codespaces uses a "Basic" sized codespace which does not have enough RAM to run a full build of VS Code and will be considerably slower during codespace start and running VS Code. You'll soon be able to use a "Standard" sized codespace (4-core, 8GB) that will be better suited for this purpose (along with even larger sizes should you need it).
1. From the [microsoft/vscode GitHub repository](https://github.com/microsoft/vscode), click on the **Code** dropdown, select **Open with Codespaces**, and the **New codespace**
2. After the codespace is up and running in your browser, press <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> and select **View: Show Remote Explorer**.
Anything you start in VS Code or the integrated terminal will appear here.

### Using VS Code with GitHub Codespaces
You will likely see better performance when accessing the codespace you created from VS Code since you can use a[VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/). Here's how to do it.
1. [Create a codespace](#quick-start---github-codespaces) if you have not already.
2. Set up [VS Code for use with GitHub Codespaces](https://docs.github.com/github/developing-online-with-codespaces/using-codespaces-in-visual-studio-code)
3. After the VS Code is up and running, press <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd>, choose **Codespaces: Connect to Codespace**, and select the codespace you created.
4. After you've connected to the codespace, use a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/) to connect to `localhost:5901` and enter `vscode` as the password.
5. Anything you start in VS Code or the integrated terminal will appear here.
This container uses the [Fluxbox](http://fluxbox.org/) window manager to keep things lean. **Right-click on the desktop** to see menu options. It works with GNOME and GTK applications, so other tools can be installed if needed.
Note that a previous run of `yarn install` will already be cached, so this step should simply pick up any recent differences.
2. After the build is complete, open a web browser or a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/) to the desktop environnement as described in the quick start and enter `vscode` as the password.
2. Go to your local VS Code client, and use Run / Debug view to launch the **VS Code** configuration. (Typically the default, so you can likely just press <kbd>F5</kbd>).
> **Note:** If launching times out, you can increase the value of `timeout` in the "VS Code", "Attach Main Process", "Attach Extension Host", and "Attach to Shared Process" configurations in [launch.json](../.vscode/launch.json). However, running `scripts/code.sh` first will set up Electron which will usually solve timeout issues.
