dbg Debugger
dbg is a CLI debugger that supports Node.js (V8/CDP), Bun (WebKit/JSC), Python (via debugpy/DAP), Java (via JDWP/DAP) and native code (C/C++/Rust/Swift via LLDB/DAP). It uses short @refs for all entities -- use them instead of long IDs.
Supported Runtimes
| Runtime | Language | Launch example |
|---|---|---|
| Node.js | JavaScript | dbg launch --brk node app.js |
| tsx / ts-node | TypeScript | dbg launch --brk tsx src/app.ts |
| Bun | JavaScript / TypeScript | dbg launch --brk bun app.ts |
| debugpy | Python | dbg launch --brk python3 app.py (or attach -- see Python section) |
| LLDB | C / C++ / Rust / Swift | dbg launch --brk --runtime lldb ./program |
| JDWP | Java | dbg launch --brk --runtime java ./program |
The runtime is auto-detected from the launch command for JS and Python runtimes. For native code, use --runtime lldb. Python can also attach to a running debugpy listener over TCP (--runtime python).
