> Regex Validate GUI Userform

A GUI user form with Tkinter that uses Regex to validate the user inputs. Also, it saves the records in a database to be able to log in and see the user information.

Project for the second-semester course "Programming Languages" (ST0244) taught at EAFIT University by prof Edison Valencia.

Features

• 🔍 Checks valid syntax of user inputs, according to certain parameters.

• 🧬 Analyzes the expressions with a regex process.

• 🗝 Saves your information in a database, to be accessed for you at any time with your username and password.

Motivation

The main aim of this project was to use regular expressions in a useful situation and go further with the project, creating something user-friendly with a GUI.

In other words, learn how to use the Python Regex Library (re) and one of the Python GUI libraries (Tkinter).

Documentation

Note: Please read the Input Instructions.

In the following documentation, we specified, some questions proposed by the prof for the presentation of this and how to use correctly the program.

Questions

Input Instructions

We used the Python Regex Library (re) to analyze the expressions according to certain patterns, created from Regular Expressions theory.

• username: Must have a minimum length of 8 characters and a maximum of 16 characters.
• name: Must contain only letters in upper or lower case.

• email: Must contain characters as letters or numbers, followed of an @ and finally a correct subdomain.

  hello@gmail.com
  

• Date of Birth: You can enter your birth date in the following formats:

  - 10/10/2015 (dd/mm/yyyy)
  - 10-10-2015 (dd-mm-yyyy)
  - 10 NOV 2010 (dd [English Abbreviation for Month] yyyy)
  - 10 NOVIEMBRE 2010 (dd [Spanish Month] yyyy)
  

  You must be 18 years or older in order to create an account

• Credit Card: The credit card number must be only American Express, Visa or Mastercard. The ExpDate must have one of the following formats (mm/yy) or (mm--yy). And the CVV must contain 3 digits.

• Password: The password to be accpeted, must have at least, upper and lower case letters, special symbols and a length of 8 characters. Remember the special symbols allowed are the following:

  --> '$'  '@'  '_'  '*'  '!'  '¡'  '-'  '#'
  

Caveats

• The database is a .txt file, the data contained there is not protected. See Contribute.

• The program has some bugs that are not solved because of its complexity and the time of development of the project. See Contribute.

• Take into account to create your development environment to run correctly the program. This program is not compiled.

• Save your credetials in a Password Manager to access your information. At the moment, the program has not a Password Recovery system.

Install

We designed the project to be able to run either on a GUI or your terminal.

GUI

1. Clone the project on your machine.

   bash git clone git@github.com:alejoriosm04/regex-validate-gui-userform.git

2. Go to the project directory (or wherever you stored it).

   bash cd regex-validate-gui-userform/src/

3. Install the dependencies using pip

   bash pip install -r requirements.txt

4. Run the program.

   bash python3 main.py

   Terminal

If you have problems running the GUI program with Tkinter, you will be able to use the user form in your terminal. At the moment, the CLI program is not linked with the database.

1. Go to the project directory (or wherever you stored it).

   bash cd regex-validate-gui-userform/cli/

2. Run the program.

   bash python3 main.py

Since this is the authors' coursework, we will not review pull requests. However, this project can be used as a basis for developing new features.

Authors in the future might add new features like link the program to a MongoDB Database in the cloud, add new features and solve some bugs.
