Support /start@fooBot command format

[betzerra]

From Telegram's Bot page:

If multiple bots are in a group, it is possible to add bot usernames to commands in order to avoid confusion:

/start@TriviaBot
/start@ApocalypseBot

This is done automatically when commands are selected via the list of suggestions. Please remember that your bot needs to be able to process commands that are followed by its username.

Is there a way to handle these automatically?
It seems that def start!(data = nil, *) only handles /start and not /start@fooBot

Hi! There is username option for a bot, or if you use Rails see this section https://github.com/telegram-bot-rb/telegram-bot#configuration-in-rails-app

For some reason I'm not able to run the bot with credentials (maybe I'm having same issue as #74 )

so my workaround was adding this code at initializers/telegram.rb

require 'telegram/bot'

Telegram.bots_config = {
  default: ENV['TELEGRAM_TOKEN']
}

Is there a way to set a username in that method?

Ok, this works:

Telegram.bots_config = {
  default: {
    token: ENV['TELEGRAM_TOKEN'],
    username: ENV['TELEGRAM_USERNAME']
  }
}
