This sample extension shows how a vscode.DebugAdapterTracker can be used to augment a debug session with additional information.
The following screencast shows a new scope "GPU" in the VARIABLES view that is fed by the extension. The underlying C++ debugger is unmodified and completely unaware of this.
The complete source is here.
- run
git clone https://github.com/weinand/augmented-debug.git - run
cd augmented-debug - run
npm install - run
code . - install the C++ extension
- F5 -> new window opens
- in new window press F5 -> debugger breaks on line 4 and VARIABLES view shows a "GPU" scope
- expand GPU scope -> 3 registers are shown
- continue stepping -> registers under GPU update their values
The vscode.DebugAdapterTracker API was designed to tap the communication between VS Code and debug adapters. It was not designed to modify messages in transit. So this example actually shows a use case that is not officially supported.
However, we are currently working on another (similar) API that supports intercepting and modifying DAP messages. And as long as this API is not a part of the official VS Code extension API (i.e. vscode.d.ts), we will continue to support the "unofficial" use case.
Initial release.
