@probe-web/dap

A Debug Adapter Protocol adapter for probe-rs that runs in the page, a worker, or Node, on top of @probe-web/client's Debugger. ProbeDebugAdapter takes DAP requests through handleMessage() and sends responses and events to onDidSendMessage() listeners, the shape VS Code web's DebugAdapterInlineImplementation expects, so an editor can debug firmware without a native adapter process.

npm install @probe-web/dap

import type { DebugProtocol as DP } from '@vscode/debugprotocol';
import { ProbeDebugAdapter } from '@probe-web/dap';

const adapter = new ProbeDebugAdapter(); // connects with connectProbeRs by default
adapter.onDidSendMessage((m) => console.log(m)); // responses and events
let seq = 1;
const send = (command: string, args?: unknown) =>
  adapter.handleMessage({ seq: seq++, type: 'request', command, arguments: args } as DP.Request);

send('initialize', { adapterID: 'probe-rs', linesStartAt1: true, columnsStartAt1: true });
send('launch', { url: 'ws://127.0.0.1:3000', token: 'secret', chip: 'MCXA153', program: '/firmware/app.elf' });
// On the `initialized` event: setBreakpoints, then configurationDone to run.

• launch / attach connect to probe-rs serve over WebSocket by default; transport: 'webusb' runs probe-rs in a worker instead (Chromium only, the probe must already be granted, and there is no disassembly).
• launch flashes program and resets the target; attach leaves it as it is.
• One core, reported as thread 1. Pass connect to supply your own debugger.

See examples/monaco-ide and examples/node-ci/dap.ts for complete clients.
