@vscode/dwarf-debugging

This repository publishes an npm module which is used by js-debug to better debug WebAssembly code when DWARF debugging information is present. You can use this in two ways:

  • For VS Code users, you will be prompted to install the appropriate extension that contains this module when you first step into a WebAssembly file.
  • For users of the js-debug standalone DAP server, you can install the @vscode/dwarf-debugging alongside js-debug or somewhere in your NODE_PATH.

This project works by compiling the Chrome C/C++ Debugging Extension in a way that is usable by Node.js programs. Fortunately, the extension is architected such that most work is done inside a WebWorker, and making this instead run in a Node worker_thread is not terribly difficult. Appropriate TypeScript types are exposed, and this module is then shimmed into js-debug which 'pretends' to be Devtools.

Contributing

Building

  1. Clone this repo, and have Docker or Podman installed.
  2. Run npm run build. This will take a while (~1hr depending on how fast your computer is.) Note that for developing you can run individual build steps in their appropriate scripts.
  3. You then have a built module. Run npm run test to run some basic tests.
