v2.7.1

Stateless nREPL Port Auto-Discovery

brepl now automatically discovers running nREPL servers when no .nrepl-port file, -p flag, or BREPL_PORT env var is found. Zero configuration required.

How it works

• Scans for Java/Clojure/Babashka processes listening on TCP ports via lsof
• Checks all candidate ports in parallel using pmap
• Validates each port with a single TCP connection (describe + CWD eval)
• Returns the first port whose working directory matches yours

Port resolution order

1. -p <port> CLI argument
2. .nrepl-port file
3. BREPL_PORT environment variable
4. Process scanning ← new

Performance

Discovery completes in ~100-200ms even with many Java processes running. Real nREPL servers respond in <5ms on localhost; non-nREPL ports are rejected within 100ms.
