Create a Telegram bot quote bot in Ruby

Source: Dev.to

Requirements

• Must have an IDE
• Project structure:

project_folder/
├── bot.rb
├── quote.rb
├── help.rb
├── start.rb
└── Gemfile

Note: No .env file is committed to git.

start.rb

# start.rb
class Start
  def initialize(bot)
    @bot = bot
    start_handler
  end

  def start_handler
    @bot.command("start") do |ctx|
      ctx.reply("welcome to quote_bot use /quote to get astonishing quotes")
    end
  end
end

telegem provides the .command method for handling / commands (e.g., /help, /start, /quote).
ctx.reply sends a reply to the current chat and accepts options such as reply_markup and parse_mode.

help.rb

# help.rb
class Help
  def initialize(bot)
    @bot = bot
    send_help_message
  end

  def send_help_message
    @bot.command("help") do |ctx|
      help_message =  3.0.4"

Gemfile

gem "httparty", "~> 0.21.0"
gem "dotenv", "~> 2.8"

Create a .env file (do not commit it) with your token:

BOT_TOKEN=
