This screen shot shows the behavior when you use following config.

- match: 'personal-.+'
    - personal-timeline
- match: '.*'
    - public-timeline

Quick start

🔧 Pre-built binary

You can download a pre-built binary from the GitHub release page for Linux and macOS. The binary for only Linux version is linked statically.

🌱 Build on your environment

If you are Rust programmer, you can isntall with cargo command,

$ cargo install telescreen

or also can build manually,

$ git clone git@github.com:mozamimy/telescreen.git
$ cd telescreen
$ cargo build --release
$ ./target/release/telescreen --help
Usage: ./target/debug/telescreen [options]

    -a, --api-key API_KEY
                        Slack API key for bot integration
    -c, --config FILE   Path to config file
    -h, --help          Print this help menu

In addition, you can build a static linked binary with muslrust Docker image.

$ docker pull clux/muslrust
$ ./exec_with_muslrust cargo build --release

📃 Create a config file

Routing rules are configurable with a file formatted as YAML. The file consits an array contains hashes like { match: regex, destinations: [channel1, channel2, ... ] }.

For example, following config sends all messages to #public-timeline channel.

- match: '.*'
    - public-timeline

On the other hand, following example also sends all messages to #public-timeline channel and sends messages posted to channels that has personal- prefix to #personal-timeline channel.

- match: 'personal-.+'
    - personal-timeline
- match: '.*'
    - public-timeline

🚀 Run

You can run telescreen like following command,

$ telescreen --api-key=[API_KEY] --config=/path/to/your/config

🐳 Run with Docker

The image is hosted in Docker Hub mozamimy/telescreen.

$ git clone git@github.com:mozamimy/telescreen.git
$ cd telescreen
$ API_KEY=[API_KEY] DEST_CHANNEL=your-channel docker-compose up
$ docker-compose down
