-# This file defines the global default configuration for docker deployments.
-# It is tracked in source control. For temporary modifications, please create
-# a separate file called ".env.local" (it's in .gitignore, so won't be tracked).
-# If a variable is defined in both files, the value in .env.local will be used.
-#
-# About the deployment procedure:
-#   We use Docker Compose to build images and launch containers for various services
-#   that make up our software suite:
-#     - sparkd
-#     - TODO: pubsub
-#     - TODO: md-publisher
-#     - TODO: webapp (DSQA on the web)
-#     - TODO: api-server (websocket based)
-#   From inside a devcontainer, you can launch all services in separate containers
-#   on your machine by running:
-#
-#     tools/deploy.sh
-#
-#   This script builds release versions for each service, packaged (generally) in
-#   self-contained directories. Next, it runs a few "docker compose" commands to
-#   build docker images loaded with the self-contained binaries from the previous
-#   step, and start containers with those images to run each service. To view the
-#   commands that deploy.sh runs internally (without actually running them), run:
-#
-#     tools/deploy.sh --dry-run
-#
-#   For additional information/help, run:
-#
-#     tools/deploy.sh --help
-#

-# C++ Intellisense for Spark on Windows (VS Code)
-**Steps**
-1. Install the **[C++ extension][cpp ext]**
-2. Install the **[CMake extension][cmake ext]**
-3. Copy `c_cpp_properties.json` from this folder to `$workspaceFolder/.vscode/`
-4. In the VS Code Command Palette, run **CMake: Select Configure Preset**, then
-   select '**spark**' from the dropdown
-
-**Notes**
-* Intellisense won't work for generated files/types until you build libspark
-
-# C++ Intellisense for Sparkd on Linux (VS Code)
-1. Install the **[CMake extension][cmake ext]**
-2. Install the **[Clangd extension][clangd ext]**
-3. (Optional) Install the **[C++ extension][cpp ext]** (*needed for debugging,
-   but intellisense should work without it*).
-4. If the **[C++ extension][cpp ext]** is installed, disable its intellisense in
-  your workspace settings (*Clangd intellisense is better*)
-   ```
-   "C_Cpp.intelliSenseEngine": "disabled"
-   ```
-5. In the VS Code Command Palette, run **CMake: Select Configure Preset**, then select the
-  **[preset][cmake presets]** you wish to build from the dropdown
-   * *The **Clang** presets may work best with the **Clangd** extension*
-   * *Intellisense won't work for generated files/types until you build libspark*

-# Sparkd Dev Container
-## How to create a VS Code [Dev Container][dev containers]
-
-1. Make sure the **[Dev Containers][dev containers ext]** extension is installed
-1. Make sure your Docker image is up to date
-   ```
-   docker pull bluetradingsystems/sparkd-dev:latest
-   ```
-1. Copy **devcontainer.json** from this folder to **$workspaceFolder/.devcontainer/**.
-
-1. In the VS Code Command Palette, run **Dev Containers: Reopen in Container**

-## How to create a Sparkd Container in the terminal (without VS Code)
-
-1. Make sure your Docker image is up to date
-   ```
-   docker pull bluetradingsystems/sparkd-dev:latest
-   ```
-2. Start the container
-   ```
-   # Replace <cont_name> with a name for the container. The container's
-   # "$HOME" dir will be mounted to "$HOME/.sparkd-dev/mounts/<cont_name> on
-   # the host
-   
-   ./start_docker.sh --container <cont_name> --mount-existing
-   ```
-   * *Replace <cont_name> with a name for the container*
-   * *The container's `$HOME` dir will be mounted to
-   `$HOME/.sparkd-dev/mounts<cont_name>` on the host*<br>
-   * *Run: `./start_docker.sh --help` to see additional options*
-3. *(Optional) Attach VS Code to the running container.*<br>
-Run **Dev Containers: Attach to Running Container** from the command palette,
-then select your container in the dropdown
-
---
-## How to update the Docker image
-
-1. Change the image by modifying the Dockerfile (don't tag arbitrary
-  images on your machine and push them to our repo on Docker Hub)
-
-1. After modifying the Dockerfile, (re)build the image
-   ```
-   # Run in this dir
-   docker build -t bluetradingsystems/sparkd-dev:latest .
-   ```
-   ***Note:** Your docker login must have write permissions to push to the
-   [sparkd-dev][docker repo sparkd-dev] repository*
-
-2. Commit the changes to Dockerfile in git
-
-3. Push the new image to Docker Hub
-
-   ```
-   docker push bluetradingsystems/sparkd-dev:latest
-   ```
-   ***Note:** The image doesn't have to be on Docker Hub, we can simply build
-   it from scratch on our local machines (with the Dockerfile). However, this
-   takes time. It is significantly quicker to download a prebuilt image, so we
-   store it on a remote repository to save time when setting up a new dev
-   machine.*

-        //                    TECHNICAL EXPLANATION.
-        //   Why the next two fields are not exposed via properties.
-        // ==============================================================
-        // These fields are of the generic parameter types, and are
-        // frequently instantiated as struct types in derived classes.
-        // Semantic actions are defined in the derived classes and refer
-        // to instance fields of these structs.  In such cases the code
-        // "get_CurrentSemanticValue().myField = blah;" will fail since
-        // the getter pushes the value of the field, not the reference.
-        // So, in the presence of properties, gppg would need to encode
-        // such field accesses as ... 
-        //  "tmp = get_CurrentSemanticValue(); // Fetch value
-        //   tmp.myField = blah;               // update
-        //   set_CurrentSemanticValue(tmp); "  // Write update back.
-        // There is no issue if TValue is restricted to be a ref type.
-        // The same explanation applies to scanner.yylval.
