Ruby Telegram Bot Message Script

send_message.rb

# TelegramMessenger Usage

# Replace 'YOUR_BOT_API_TOKEN' and 'CHAT_ID' with your actual bot token and chat ID
bot_token = 'your-bot-token'
chat_id = 'your-chat-id'

# Create an instance of the TelegramMessenger class
telegramer = TelegramMessenger.new(bot_token, chat_id)

# Create a multi-line string for the message
message = <<~MESSAGE
    Check out *this* ruby method:

    ```ruby
    def foo 
        puts "bar"
    end    
    ```

    Now you can see the code in a code block.

    This is a test message.
MESSAGE

# Find the chat_id by running (look in the output for the chat_id). 
# You will need to have sent a message recently to the bot to get the chat_id.
telegramer.get_updates

# Once you have a chat_id, update the file with the chat_id and run the following to send a message:
#telegramer.send_message(message)
