About:
Gpp is a general-purpose preprocessor that allows users to define their own macro syntax and delimiters. It processes text files by expanding macros and handling conditional inclusions, making it highly adaptable for various markup languages and custom build pipelines. Its main value proposition is providing a flexible, lightweight preprocessing tool independent of any specific programming language or framework.

Key Features:

Fully customizable macro syntax and delimiters
Supports conditional compilation and file inclusion
Lightweight and standalone with no external dependencies
Suitable for preprocessing arbitrary text formats

Use Cases:

Generating configuration files from templates
Preprocessing custom markup or documentation
Managing conditional code in language-agnostic projects

Alternatives:

m4 – Standard UNIX macro processor with fixed syntax, less flexible than Gpp
cpp – C preprocessor tied to C/C++ syntax, not easily adaptable for other formats
