# Code - OSS Development Container

This repository includes configuration for a development container for working with Code - OSS in a 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` and a web client is available on port `6080`.

## Quick start - local

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 a full build. If you are on macOS, or are using the old Hyper-V engine for Windows, update these values for Docker Desktop by right-clicking on the Docker status bar item and 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:** 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.

4. Press <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> or <kbd>F1</kbd> and select **Remote-Containers: Clone Repository in Container Volume...**.

    > **Tip:** While you can use your local source tree instead, operations like `yarn install` can be slow on macOS or when 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.

5. Type `https://github.com/microsoft/vscode` (or a branch or PR URL) in the input box and press <kbd>Enter</kbd>.

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.

Anything you start in VS Code, or the integrated terminal, will appear here.

## Quick start - GitHub Codespaces

1. From the [microsoft/vscode GitHub repository](https://github.com/microsoft/vscode), click on the **Code** dropdown, select **Open with Codespaces**, and then click on **New codespace**. If prompted, select the **Standard** machine size (which is also the default).

   > **Note:** You will not see these options within GitHub if you are not in the Codespaces beta.

2. After the codespace is up and running in your browser, press <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> or <kbd>F1</kbd> and select **Ports: Focus on Ports View**.

3. You should see **VNC web client (6080)** under in the list of ports. Select the line and click on the globe icon to open it in a browser tab.

    > **Tip:** If you do not see the port, <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> or <kbd>F1</kbd>, select **Forward a Port** and enter port `6080`.

4. In the new tab, you should see noVNC. Click **Connect** and enter `vscode` as the password.

Anything you start in VS Code, or the integrated terminal, will appear here.

### Using VS Code with GitHub Codespaces

You may see improved VNC responsiveness when accessing a codespace from VS Code client since you can use a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/). Here's how to do it.

1.  Install [Visual Studio Code Stable](https://code.visualstudio.com/) or [Insiders](https://code.visualstudio.com/insiders/) and the the [GitHub Codespaces extension](https://marketplace.visualstudio.com/items?itemName=GitHub.codespaces).

	> **Note:** The GitHub Codespaces extension requires the Visual Studio Code distribution of Code - OSS.

2. After the VS Code is up and running, press <kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd> or <kbd>F1</kbd>, choose **Codespaces: Create New Codespace**, and use the following settings:
    - `microsoft/vscode` for the repository.
	- Select any branch (e.g. **main**) - you select a different one later.
	- Choose **Standard** (4-core, 8GB) as the size.

4. After you have connected to the codespace, you can use a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/) to connect to `localhost:5901` and enter `vscode` as the password.

    > **Tip:** You may also need change your VNC client's **Picture Quaility** setting to **High** to get a full color desktop.

5. Anything you start in VS Code, or the integrated terminal, will appear here.

## Try it!

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:** You can also set the resolution from the command line by typing `set-resolution`.

To start working with Code - OSS, follow these steps:

1. In your local VS Code client, open a terminal (<kbd>Ctrl/Cmd</kbd> + <kbd>Shift</kbd> + <kbd>\`</kbd>) and type the following commands:

    ```bash
    yarn install
    bash scripts/code.sh
    ```

2. After the build is complete, open a web browser or a [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/) to connect to the desktop environment as described in the quick start and enter `vscode` as the password.

3. You should now see Code - OSS!

Next, let's try debugging.

1. Shut down Code - OSS by clicking the box in the upper right corner of the Code - OSS window through your browser or VNC viewer.

2. Go to your local VS Code client, and use the **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.

3. After a bit, Code - OSS will appear with the debugger attached!

Enjoy!
