# telegram_actor

A proxy for communicating with [TDLib](https://core.telegram.org/tdlib/docs/td__json__client_8h.html) over Syndicate using the JSON-serialized object API.

## Do not use Telegram.

Probably a front for gathering metadata, like Signal, except FSB.

## Example config
```
#!/usr/bin/env -S syndicate-server --config

<require-service <daemon telegram_actor>>

<daemon telegram_actor {
  argv: [ "/bin/telegram_actor" ]
  restart: never
  protocol: application/syndicate
}>

let ?ds = dataspace

? <service-object <daemon telegram_actor> ?cap> [
  $cap ? <telegram-recv-error ?err> [ $log ! <log "-" { telegram-recv-error: $err }> ]
  $cap <telegram-client { dataspace: $ds }>
