Go Conference Ticket Booker CLI

A simple command-line interface (CLI) application built in Go for booking tickets to the "Go Conference".

Description

This application simulates a ticket booking system. Users can input their details to book a certain number of tickets for the "Go Conference". The system validates the input, manages available ticket inventory, and simulates sending a confirmation ticket asynchronously.

Features

• Command-Line Interface: All interactions happen through the terminal.
• User Input: Collects first name, last name, email address, and the number of tickets to book.
• Input Validation:
  • Checks if first and last names are at least 2 characters long.
  • Checks if the email address contains an "@" symbol.
  • Checks if the requested number of tickets is positive and does not exceed the remaining available tickets.
• Ticket Booking:
  • Stores booking information (name, email, tickets booked).
  • Decrements the count of remaining tickets.
• Inventory Management: Tracks the total and remaining tickets for the conference.
• Sold Out Notification: Informs the user when the conference is fully booked.
• Asynchronous Ticket Sending: Simulates sending tickets in the background using goroutines (with a 5-second delay for demonstration).
• Display Bookings: Shows a list of first names of users who have booked tickets.

Prerequisites

• Go (version 1.x or higher) installed on your system.

How to Run

1. Clone or Download: If this project were in a repository, you would clone it. For now, ensure you have main.go and helper.go in the same directory.

2. Navigate to the Directory: Open your terminal or command prompt and navigate to the directory where you saved the Go files.

   cd path/to/your/CLI-ticket-booking-Go

3. Run the Application: You can run the application directly using:

   go run main.go helper.go

   Alternatively, you can build an executable:

   go build -o ticket-booker main.go helper.go

   And then run the executable:

   ./ticket-booker  # On Linux/macOS
   .\ticket-booker.exe # On Windows

4. Interact with the Application: The application will greet you and prompt for your details:

   • Enter your first name
   • Enter your last name
   • Enter your email address
   • Enter the number of tickets you want to book

   Follow the on-screen prompts. If your input is valid, your booking will be confirmed, and a simulated ticket-sending process will begin.

Project Structure

• main.go: Contains the main application logic, user interaction, booking functions, and goroutine management.
• helper.go: Contains helper functions, primarily for input validation.

Potential Future Enhancements

• More robust error handling for user input (e.g., non-integer input for tickets).
• Persistent storage for bookings (e.g., saving to a file like CSV or JSON, or a database).
• Option to view all booking details (not just first names).
• Option to cancel bookings.
• Improved UI/UX for error messages (e.g., consolidating all validation errors).
