Setting up Visual Studio Code

These instructions cover setting up Visual Studio Code to build the CMake project.

A working knowledge of using and configuring Visual Studio Code is assumed.

Requirements

You'll need to install:

Then open the cloned repository with "Open folder...".

Windows specific setup

Windows needs a little help to find the required dependencies for local builds.

  • First download SDL as described in the Visual Studio docs.
  • Add "SDL2_DIR": "${workspaceRoot}/vs/sdl/" to configureSettings (See "CMake Arguments" below)

Mac specific setup

If you are running Catalina or higher, you may find difficulty in debugging local builds. To fix this, you need to install the CodeLLDB extension. Add a 'Build and attach' configuration like so:

  • Add a configuration with Debug > Add Configuration
  • Paste in the following
{
   "name": "Launch and Debug",
   "type": "lldb",
   "request": "launch",
   "program": "${command:cmake.launchTargetPath}"
}

Now, when you want to attach the debugger, run with that configuration and now your breakpoints will be respected 🎉

Initial setup for local builds

You should get a notification asking if you want to configure the project. Click "Yes" and select "[Unspecified]" from the "Select a Kit" dropdown for a local build with the default compiler.

You should now be able to build by pressing the "⚙ Build:" button, or F7. You can also run an example by pressing Shift + F5 and debug by pressing the "Debug" button or Ctrl + F5.

IntelliSense

After configuring the project a "CMake Tools would like to configure IntelliSense for this folder." notification should appear, click "Allow" to configure IntelliSense. If the notification does not appear, open the command palette (Ctrl/Cmd + Shift + P) run "C/C++: Change Configuration Provider..." and select "CMake Tools".

CMake Arguments

To set CMake arguments (like -D32BLIT_PATH for out-of-tree builds), you need to add them to .vscode/settings.json:

{
  // other options...
  "cmake.configureSettings": {
    "32BLIT_PATH": "/path/to/32blit-beta"
  },
}

Debugger configuration

You will need to create a launch.json file for debugging on some platforms, you should set program to ${command:cmake.launchTargetPath} and cwd to ${workspaceFolder}/build. See the CMake Tools documentation for more details.

Building for 32Blit

Open the command palette (Ctrl/Cmd + Shift + P) and run "CMake: Edit User-Local CMake Kits".

Add this to the list:

  {
    "name": "32Blit",
    "toolchainFile": "/path/to/32blit-beta/32blit.toolchain"
  },

(Replacing /path/to/32blit-beta, with the actual path.)

You should now be able to select "32Blit" as a kit. ("CMake: Change Kit" from the command palette or the button displaying the current kit at the bottom of the window). If you select a target ending with .flash from the list next to the "⚙ Build:" button, that example will be flashed to your device when you build.
