CLI to pipe data through Redis Pub/Sub

rp - Redis Pipe

Install

go get github.com/whee/rp/cmd/rp

Usage

rp      read  <name>...
rp [-p] write <name>...
rp      -n <network> -a <address> read  <name>...
rp [-p] -n <network> -a <address> write <name>...

Options:
  -p, --passthrough  Pass written data to standard output.
  -n, --network <network>  Network of the Redis server [default: tcp]
  -a, --address <address>  Address of the Redis server [default: :6379]

Basics

rp converts standard input and output to networked pipes via Redis Pub/Sub. This allows trivial construction of MIMO data flows for processing and analysis.

For example:

Terminal 1> $ rp read foo | jq --unbuffered '.c' | rp write cs
Terminal 2> $ rp read foo | jq '.'
Terminal 3> $ rp read cs
Terminal 4> $ echo '{"a":1,"b":2,"c":"foo"}' | rp write foo
Terminal 2> {
Terminal 2>     "a": 1,
Terminal 2>     "b": 2,
Terminal 2>     "c": "foo"
Terminal 2> }
Terminal 3> "foo"
