About:
abnfgen is a command-line utility that generates random text strings based on a given Augmented Backus-Naur Form (ABNF) grammar definition. It is designed for robustness testing of parsers, protocol implementations, and text processing tools by creating valid and edge-case inputs. This helps developers identify parsing errors and boundary conditions in their software.

Key Features:

Generates random documents from ABNF grammar specifications
Supports recursive and complex grammar structures
Useful for fuzzing and stress-testing parsers
Lightweight and fast command-line interface

Use Cases:

Fuzzing network protocol parsers for security vulnerabilities
Generating test data for custom file format readers
Validating the robustness of ABNF-compliant text processors

Alternatives:

yacc/bison – Generators for LALR parsers, whereas abnfgen focuses on generating input data rather than parsing logic.
Python 'hypothesis' library – A property-based testing framework that can generate data, but abnfgen is specialized for ABNF grammars specifically.
