Regex Generator

A Python tool for dynamically generating regex patterns from strings and bytes.

RegexGen

RegexGen is a versatile Python tool designed to automatically generate regular expression (regex) patterns from given input data, which works with strings and bytes. This tool simplifies the process of creating regex patterns for various applications, including data validation, parsing, and extraction tasks.

Features

• Dynamic Regex Generation: Automatically generates regex patterns for strings and byte sequences.
• Custom Character Support: Allows customization of regex patterns for specific characters.
• Testing Utility: Includes a method for testing generated regex patterns against provided or auto-generated data.

Installation

To use RegexGen, clone this repository or download the source code. No external dependencies are required beyond the Python standard library.

git clone https://github.com/memoryapi/RegexGen/tree/main

Usage

Basic Usage

Text Data

from RegexGenerator import RegexGenerator

dataText = "Hello123 World!"
rgText = RegexGenerator(dataText)
regexText = rgText.generate()
print(f"Generated Regex Pattern: {regexText}")

Byte Data

from RegexGenerator import RegexGenerator

dataBytes = b'\x00\x00\x00N\x00\t$\x93\x8d\x86S-|\xd94\xa2\x99@\x00\x00\x00'
rgBytes = RegexGenerator(dataBytes)
regexBytes = rgBytes.generate()
print(f"Generated Regex Pattern: {regexBytes}")

Custom Character Mapping

customChars = {'H': '[Hh]', 'e': '[eE]', '!': '[!1]'}
rgCustom = RegexGenerator("Hello World!", customChars)
regexCustom = rgCustom.generate()
print(f"Generated Regex Pattern with Custom Characters: {regexCustom}")

Testing Regex Patterns

extractedText = rgText.test(regexText)
print(f"Extracted Text: {extractedText}")

[!} see main.py for test cases.
