Vk chat bot

Bot follow scenario for ordering tickets through vk.com.

Demonstration

Bot supports commands:

• '/t', '/ticket', 'заказ', 'регистрация', '1' — start scenario;
• '/h', '/help', 'помощь', '2' — instruction about the work of the bot.

Script steps:

1. Entering the city of departure. Checking a city using regular expression, suggest a city where we can fly
2. Entering the destination city. Checking a city using regular expression, suggest a city where we can fly
   * If there is no flight between the selected cities, we text about it and complete the scenario.
3. Entering the date: we ask the user for the departure date in the YYYY-mm-dd format.
4. Selecting a flight. With the help of the dispatcher, we offer 5 flights closest to the selected date, indicating their numbers and ask enter the number you like.
5. Specify the number of places (from 1 to 5).
6. Suggest writing a comment in any form.
7. Clarify the entered data.
8. Request a phone number.
9. Inform user that he will be contacted by the entered number.

If a command (/ ticket or / help) is entered during a script, the script stops and the command is executed.
