Task Force Beta Bot

General-purpose Telegram bot with modular handler architecture.

Build & Run

cargo build --release

Usage

task_force_beta_bot <token_file> <allowed_chats_file>

Both arguments are required:

token_file - Path to file containing the Telegram bot token
allowed_chats_file - Path to file containing allowed chat IDs

Example:

cargo run -- /path/to/token /path/to/allowed_chats

Allowed Chats File

One chat ID per line. Lines starting with # are comments.

# My group
-100123456789

The bot ignores messages from chats not in this list.

Architecture

src/main.rs - Entry point, dispatcher setup
src/config.rs - Token and allowed chats loading from CLI arguments
src/handlers/ - Message handlers (modular, each feature in own file)
src/utils/ - Shared utilities

NixOS Deployment

Module location: /home/fabian/nix/sys/modules/task-force-beta-bot.nix

local.sys.task-force-beta-bot = {
  enable = true;
  tokenFile = "/var/trust/task_force_beta_bot/telegram_token";
  allowedChats = [ (-1001234567890) ];  # Negative IDs for groups
};

The module:

Fetches and builds the package from git
Generates the allowed chats file in the nix store
Runs as a hardened systemd service (task-force-beta-bot.service)

After code changes: update rev and hash in the module's fetchgit block.

Adding New Handlers

Create src/handlers/new_feature.rs
Export in src/handlers/mod.rs
Add handler branch in handlers::schema()
