-# 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*

-2. Start the container
-   ```
-   # Replace <cont_name> with a name for the container. The container's

-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.

-        //                    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.
