Create a Telegram bot quote bot in Ruby

#ruby #telegem #telegram

Create a bot quote bot to be precise

Requirements

Must have an ide
Basic or advanced knowledge in Ruby

project_folder/
├── bot.rb
├── quote.rb
├── help.rb
├── start.rb
└── Gemfile
Enter fullscreen mode Exit fullscreen mode

Note: no .env here cause it’s meant to be secure and not to be commited to git

  • Let’s start with 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
Enter fullscreen mode Exit fullscreen mode 
this file uses telegem two methods one .command this helps you with handling / commands e.g /help /start /quote and so on 
second is the ctx.reply method this is used to send a reply back to the current chat it automatically adds the id and it can take **options e.g reply_markup, parse_mode and so on with time you will eventually see how they are been used
Enter fullscreen mode Exit fullscreen 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 = <<~TEXT 
     use /quote to get quotes 
   use /help to show this help message 
   TEXT
    ctx.reply(help_message, parse_mode: 'Markdown') 
    end 
  end 
end
Enter fullscreen mode Exit fullscreen mode

-quote.rb

this is where knowledge in some gems is required in this special case we using httparty

require 'httparty'
require 'json'

class Quote
  def initialize(bot)
    @bot = bot 
     find_quotes
   end 
   def find_quotes
    @bot.command("quote") do |ctx| 
     response = HTTParty.get("https://zenquotes.io/api/random")
    if response.success?
      data = JSON.parse(response.body)
      quote_data = data.first 
       quote = quote_data['q'] 
       author = quote_data['a']
    message = <<~TEXT
    QUOTE OF THE DAY 
    quote: #{quote}
     author: #{author}
     credit: zenquotes
    TEXT 
    ctx.reply(message, parse_mode: 'Markdown')
  else 
     ctx.reply("failed to fetch code")
     end 
   end 
 end 
end
Enter fullscreen mode Exit fullscreen mode

-bot.rb the main file

#bot.rb
require 'telegem'
require 'dotenv/load'

require_relative 'help'
require_relative 'start'
require_relative 'quote'

bot = Telegem.new(ENV['BOT_TOKEN'])

Start.new(bot)
Help.new(bot)
Quote.new(bot)

bot.start_polling 
puts "bot has started")
Enter fullscreen mode Exit fullscreen mode
  • now we need our Gemfile 
source 'https://rubygems.org' 

gem "telegem", "~>3.0.4"
gem "httparty", "~>0.21.0"
gem "dotenv", "~>2.8"
Enter fullscreen mode Exit fullscreen mode

important don’t forget your .env

BOT_TOKEN=<your token here>
Enter fullscreen mode Exit fullscreen mode

Now we need to install and run using bundle

-if you don’t have bundle gem still works or run

$ gem install bundle
Enter fullscreen mode Exit fullscreen mode
  • now you can run using bundle but first let’s install all gems we need 
$ bundle install
Enter fullscreen mode Exit fullscreen mode

Then now we run our code

$ bundle exec ruby bot.rb
Enter fullscreen mode Exit fullscreen mode
