castit

Post Multiple Message to Multiple Channel with single command.

castit is a tool to send slack message to multiple channel with only single command.

Think of situation like working remotely and you belong to multiple teams. If you need to send Good Morning! Stated Working! to multiple team's channel, this tool is for you.

Just write config like below

token: "<MY-TOKEN>"
casts:
  - channel: "#teamA"
    content: "good morning"
  - channel: "#teamB"
    content: "Started Working"
  - channel: "#teamC"
    content: "Office Hour Stared. Just ask me anything."

and run

java -jar castit.jar --config=/path/to/config.yml

Supported Command

Usage: cast [OPTIONS]

Options:
  --config PATH
  --cast TEXT    cast name
  -h, --help     Show this message and exit

Quick Start

You can install via Homebrew

$ brew tap omuomugin/tap

$ brew install castit

Getting your token for Slack

TBD

You need to create an app to your slack channel as a user.

see https://api.slack.com/apps

Writing Yaml

You need a config file written in yaml. (other type will be supported in near future maybe).

token: "<MY-TOKEN>"
casts:
  - name: "start"
    messages:
      - channel: "#teamA"
        content: "good morning"
      - channel: "#teamB"
        content: "Started Working"
      - channel: "#teamC"
        content: "Office Hour Stared. Just ask me anything."

Ofcourse you can create multiple cast type. You might want to write another cast type like below.

token: MY TOKEN
casts:
  - name: "start"
    messages:
      - channel: "#teamA"
        content: "good morning"
      - channel: "#teamB"
        content: "Started Working"
      - channel: "#teamC"
        content: "Office Hour Stared. Just ask me anything."
  - name: "end"
    messages:
      - channel: "#teamA"
        content: "good night"
      - channel: "#teamB"
        content: "Finished Working. Have a good evening"
      - channel: "#teamC"
        content: "Office Hour Ended. Please talk to me tomorrow."

Run and cast (like multi cast) your messages

castit --config=path/to/your/config.yaml --cast=start

Technical Things

Whole CLI tool is written in Kotlin.

And I want to thank all of the great libraries out there.

ajalt/clikt for basic CLI implementation
kittinunf/fuel for Http Request
charleskorn/kaml for serializing, desirializing YAML

How to start it locally

Thanks to johnrengelman/shadow , it is easy to build fat jar which can use it from command line.

./gradlew clean shadowjar

and you just run jar with command.

java -jar build/libs/castit-x.y.z-all.jar --help
