Install

Add to your gemfile:

gem 'tdlib-ruby'

and run bundle install.

Or just run gem install tdlib-ruby

Basic authentication example

require 'tdlib-ruby'

TD.configure do |config|
  config.lib_path = 'path_to_dir_containing_tdlibjson'

  config.client.api_id = your_api_id
  config.client.api_hash = 'your_api_hash'
end

TD::Api.set_log_verbosity_level(1)

client = TD::Client.new

begin
  state = nil

  client.on(TD::Types::Update::AuthorizationState) do |update|
    state = case update.authorization_state
            when TD::Types::AuthorizationState::WaitPhoneNumber
              :wait_phone_number
            when TD::Types::AuthorizationState::WaitCode
              :wait_code
            when TD::Types::AuthorizationState::WaitPassword
              :wait_password
            when TD::Types::AuthorizationState::Ready
              :ready
            else
              nil
            end
  end

  client.connect

  loop do
    case state
    when :wait_phone_number
      puts 'Please, enter your phone number:'
      phone = STDIN.gets.strip
      client.set_authentication_phone_number(phone, nil).wait
    when :wait_code
      puts 'Please, enter code from SMS:'
      code = STDIN.gets.strip
      client.check_authentication_code(code).wait
    when :wait_password
      puts 'Please, enter 2FA password:'
      password = STDIN.gets.strip
      client.check_authentication_password(password).wait
    when :ready
      client.get_me.then { |user| @me = user }.rescue { |err| puts "error: #{err}" }.wait
      break
    end
    sleep 0.1
  end

ensure
  client.dispose
end

p @me

Client methods are being executed asynchronously and return Concurrent::Promises::Future (see: https://github.com/ruby-concurrency/concurrent-ruby/blob/master/docs-source/promises.in.md).

Configuration

TD.configure do |config|
  config.lib_path = 'path/to/dir_containing_libtdjson' # libtdson will be searched in this directory (*.so, *.dylib, *.dll are valid extensions). For Rails projects, if not set, will be considered as project_root_path/vendor. If not set and file doesn't exist in vendor, it will try to find lib by ldconfig (only on Linux).
  config.encryption_key = 'your_encryption_key' # it's not required

  config.client.api_id = 12345
  config.client.api_hash = 'your_api_hash'
  config.client.use_test_dc = true # default: false
  config.client.database_directory = 'path/to/db/dir' # default: "#{Dir.home}/.tdlib-ruby/db"
  config.client.files_directory = 'path/to/files/dir' # default: "#{Dir.home}/.tdlib-ruby/files"
  config.client.use_file_database = true # default: true
  config.client.use_chat_info_database = true # default: true
  config.client.use_secret_chats = true # default: true
  config.client.use_message_database = true # default: true
  config.client.system_language_code = 'ru' # default: 'en'
  config.client.device_model = 'Some device model' # default: 'Ruby TD client'
  config.client.system_version = '42' # default: 'Unknown'
  config.client.application_version = '1.0' # default: '1.0'
  config.client.enable_storage_optimizer = true # default: true
  config.client.ignore_file_names = true # default: false
end

Advanced

You can get rid of large tdlib log with

TD::Api.set_log_verbosity_level(1)

You can also set log file path:

TD::Api.set_log_file_path('path/to/log_file')

Additional options can be passed to client:

TD::Client.new(database_directory: 'will override value from config',
               files_directory: 'will override value from config')

If the tdlib schema changes, then ./bin/parse can be run to synchronize the Ruby types with the new schema. Please look through lib/tdlib/client_methods.rb carefully, especially the set_password method!
