Public Service Announcer

PSA can multiplex annoucements, important or otherwise.

It's a single binary that works as a CLI for sending messages from a console, and can provide announcements as a service via e.g. a webhook.

Usage

Usage of ./psa:
  -dryrun
    	validate and log but don't send anything
  -message string
    	the message to announce
  -v	verbose logging

Configuration

For information on how to prepare your Discord server or Slack workspace for receiving announcements, see the Discord webhooks intro or Slack webhooks API guide.

All configuration is optional, but without any there will be nowhere to announce messages.

export PSA_DISCORD_WEBHOOK="https://discord.com/api/webhooks/.../..."
export PSA_SLACK_WEBHOOK="https://hooks.slack.com/services/.../.../..."

If you want to customize the way announcements are presented, you can set PSA_MSG_TEMPLATE in your environment:

export PSA_MSG_TEMPLATE="📣 {{.Message}}"

.Message is (currently) the only field available to the template. If your template does not use it, psa will not send anything.

TODO

• CLI for sending
• Discord announce
• Slack announce
• incoming webhook (HMAC verification)
• Twitter announce
• configuration by simple file in ~/.config (simplifying CLI use)
• more configurable announcement sinks (e.g. multiple Discord hooks)

Maybe TODO

• Structured logging
• RBAC (users authenticated by e.g. Slack can be authorized to announce)
• Announce from Slack or Discord
• More integrations
  • IRC, email, text messages, Signal, Telegram, Cabal
