omq 0.6.4

Pure Ruby implementation of the ZMTP 3.1 wire protocol (ZeroMQ) with all socket types (REQ/REP, PUB/SUB, PUSH/PULL, DEALER/ROUTER, and draft types) and TCP/IPC/inproc transports. Includes an `omq` CLI for composable message pipelines — pipe, filter, and transform across processes with Ruby eval, multiple formats (JSON, msgpack, marshal), Ractor parallelism, and compression. No native libraries required.
