ModularApp

A modular C++17 software project demonstrating clean module separation, CMake build system, and Doxygen-style API documentation.

Features

• Logger Module — Hierarchical log output (DEBUG / INFO / WARN / ERROR)
• ConfigManager Module — Parse and manage key=value configuration files
• DataManager Module — In-memory data caching and lifecycle management
• Utils Module — String trimming, splitting, time formatting, file path helpers
• Processor Module — Core business logic processing with dependency injection
• Adapter Module — CLI argument parsing (--config, --help, --version)
