touch Gemfile touch bot.rb atom .
This produces two blank documents, one for specifying the gems you’ll need and one in which the bot’s laws will live. The past demand opens both of these data in Atom.
Click the Gemfile in Atom’s sidebar, and paste the following in:
This tells Bundler to grab the Ruby software to the Telegram API from rubygems.
To complete the gem create, get back to their terminal and type package . Here’s what you should read:
That’s it your gem build, now we’re eventually obtaining on the code.
Programming the first Telegram robot
The signal that is going to feel operating continuously regarding the servers try inside bot.rb. It’s unused immediately, but here we’re browsing link when you look at the Telegram gem we just bundled and create a bot.
It’s very little code to write. By the point you are really completed, https://hookupwebsites.org/naughtydate-review/ this is exactly what you’ll need:
