How hugoarco/powershell-payment-discount-manager works
1. Repo shape
- This is a very small, script-first repository: one PowerShell entrypoint (descuentos.ps1) plus documentation and license.
- Architecturally, it is a single executable CLI tool, not a multi-module app or service.
2. Primary runtime
- The whole system runs in PowerShell 5.0+ on Windows 10/11.
- There is no backend, database, or external API dependency shown in the repo; all behavior appears local and interactive.
3. User interaction boundary
- The main boundary is the interactive console session.
- The script collects a user name, presents a colored menu, and drives all features through prompts and selections.
4. Identity / role handling
- The README says users are identified as students / teachers, with names omitted for privacy except the author example.
- This implies a lightweight in-memory user identity step used to personalize output rather than a persistent account system.
5. Discount calculation subsystem
- One core function is discount computation with validation from 0–100%.
- This subsystem likely takes an original price and discount percent, validates the range, and returns a discounted total for comparison.
6. Payment processing subsystem
- Another key branch is payment method handling for Visa, PayPal, and Mastercard.
- Since no external integration is documented, treat this as an internal decision/validation layer rather than real gateway connectivity.
7. Security-sensitive input
- The script uses SecureString for password handling.
- This is the only explicitly security-oriented mechanism mentioned, so the architecture includes a protected input path for credentials separate from normal text prompts.
8. Ticket generation output
- After processing, the script can generate a .txt ticket.
- That makes file output a distinct terminal step in the flow: user input → calculation/payment logic → text receipt generation on disk.
9. Control flow model
- The application is organized around a menu-driven dispatcher.
- The menu likely routes into a few isolated operations: identify user, calculate discount, compare prices, process payment, and emit a ticket.
10. Data flow summary
- Input comes from the console, is validated and transformed in-memory, and then exits in two forms:
- on-screen feedback with colorized messages
- persisted ticket text files
- There is no evidence of long-lived state, so the data flow is ephemeral and session-based.
11. Operational constraints
- The README notes administrator rights are optional, which suggests the script mostly uses standard user-level file and console capabilities.
- The only probable environmental dependency is the Windows PowerShell host itself.
12. How to diagram it
- Draw this as a single-node CLI application with four internal areas:
- interactive UI/menu
- validation and calculation
- payment method branch
- ticket/file writer
- Keep external boundaries minimal: just the Windows PowerShell runtime and the local filesystem for ticket export.
