exrex_variant_generator

exrex_variant_generator is a Python package that leverages regular expressions to generate all possible string variants. It can handle standard regex patterns by expanding them into all matching strings, or it can interpret custom string formats with bracketed options to generate combinations.

Installation

To install exrex_variant_generator, use pip:

pip install exrex_variant_generator

Usage

Using exrex_variant_generator is straightforward.

Generating variants from a custom string with options:

This mode interprets strings like 'a[bc]d' to generate combinations.

from exrex_variant_generator import generate_variants

custom_pattern = 'user[123]_pref[a|b]'
variants = generate_variants(custom_pattern)
print(variants)
# Output: ['user1_prefa', 'user1_pref b', 'user2_prefa', 'user2_pref b', 'user3_prefa', 'user3_pref b']

Generating variants from a strict regex pattern:

This mode uses the exrex library to generate all strings matching a given regex.

from exrex_variant_generator import generate_variants

regex_pattern = '[a-c]{2}'
variants = generate_variants(regex_pattern)
print(variants)
# Output: ['aa', 'ab', 'ac', 'ba', 'bb', 'bc', 'ca', 'cb', 'cc']
