About:
Regldg is a specialized tool that generates dictionary files for use with regular expression engines. It allows developers to create comprehensive word lists based on specific grammatical rules, which can then be used to test or break regex patterns. This is invaluable for security professionals and developers needing to validate complex regex logic against exhaustive inputs.

Key Features:

Generates dictionary files based on regex grammar
Supports custom character sets and repetition rules
Outputs compatible with standard regex testing tools
Command-line interface for automation
Helps identify regex vulnerabilities

Use Cases:

Security auditing of regex patterns
Generating test data for regex validation
Creating wordlists for password cracking simulations
Learning regex behavior with concrete examples

Alternatives:

crunch – Crunch generates wordlists based on character sets, while regldg generates based on regex grammar patterns
regex101 – Regex101 is a visual debugger, while regldg generates actual dictionary data for testing
