VHTG - Valheim to Telegram Message Processor

VHTG is a command-line application written in Go that reads text messages from the standard input or a Docker container with the Valheim server, matches them using regular expressions, and sends formatted messages to a specified Telegram chat using the Telegram Bot API.

Features

• Automatically process Valheim server logs
• Support for reading logs from standard input or a Docker container
• Send formatted messages to a specified Telegram chat
• Test mode for outputting formatted messages without sending them to Telegram

Prerequisites

• Go 1.18 or higher
• A Telegram bot token (you can create a new bot by talking to the BotFather)
• A Telegram chat ID to send messages to (you can use a personal chat, group chat, or channel)

Installation

Clone the repository and navigate to the project directory:

git clone https://github.com/ffix/vhtg.git
cd vhtg

Build

Use the provided Makefile to build the application for your platform:

make vhtg # For your current platform
make all  # For all supported platforms

Usage

1. Set the TELEGRAM_BOT_TOKEN, TELEGRAM_CHAT_ID, and SERVER_PASS environment variables:

export TELEGRAM_BOT_TOKEN="your-telegram-bot-token"
export TELEGRAM_CHAT_ID="your-telegram-chat-id"
export SERVER_PASS="your-server-password"

2. In standard mode, pipe the application from the Valheim server:

./valheim-server | ./vhtg

3. To enable test mode and only output the formatted message to the standard output without sending it to Telegram, add the --test flag:

./valheim-server | ./vhtg --test

4. To integrate with Docker and poll the logs internally, add the --docker flag:

./vhtg --docker
