gram

Gram is an executable that utilizes the Telegram Database Library & Bot API to make your life easier.

Usage

Prerequisites

• Nix
• A .env file with the following fields:
  • API_ID: App api_id field under My Telegram > App Configuration
  • API_HASH: App api_hash field under My Telegram > App Configuration
  • API_PHONE_NUMBER: This will be used for phone verification of Telegram API, enter in international format

Running

user@machine:~/src/gram$ nix-build
> [2 built, 0.0 MiB DL]
user@machine:~/src/gram$ nix-shell
> gram.cabal is up-to-date
[nix-shell:~/src/gram]$ gram -c <CHAT_ID>

Once gram starts running you'll receive a verification code on the Telegram app, insert that into /tmp/code.

Deployment

Prerequisites

• Nixops (Install using nix-env -i nixops)
• Have your DigitalOcean token in env variable: export DIGITAL_OCEAN_AUTH_TOKEN=<token>

Create Deployment

$ nixops create nix/trivial.nix nix/trivial-digital-ocean.nix

$ nixops deploy

This will create a new Droplet in DigitalOcean & create the gram as a systemd service.
