The `pub` utility publishes input from stdin to a redis channel and the `sub`

utility consumes from a redis channel, writing to stdout.

## Quickstart

Publishing to Redis from `stdin` is easy with the `pub` utility:

```shell

$ pub --help

Pipe stdin to a redis pub/sub channel

Usage: pub --channel TEXT [--host STRING] [--port INTEGER] [--db INTEGER]

           [--version]

Available options:

  -h,--help                Show this help text

  --channel TEXT           Redis channel to publish to

  --host STRING            Redis host (default: localhost)

  --port INTEGER           Redis post (default: 6379)

  --db INTEGER             Redis db (default: 0)

$ journalctl -f nginx.service | pub --channel "nginx-loglines"

```

and subscribing to Redis channels and piping to `stdout` is also easy with the

`sub` utility:

```shell

$ sub --help

Subscribe to redis channels and pipe to stdout

Usage: sub [--channel TEXT]... [--host STRING] [--port INTEGER] [--db INTEGER]

           [--version]

Available options:

  -h,--help                Show this help text

  --channel TEXT...        Redis channel(s) to subscribe to

  --host STRING            Redis host (default: localhost)

  --port INTEGER           Redis post (default: 6379)

  --db INTEGER             Redis db (default: 0)

$ sub --channel "nginx-loglines" --channel "haproxy-loglines" # This subscribes to both redis channels

```

## Building

You can build multiple ways:

- `stack build`

- `cabal build`

- `nix-build --not-out-link -A pub release.nix`

- `nix-shell -A pub.env release.nix`
