Detailed Description

This header defines a comprehensive configuration management system that handles loading, parsing, validation, and access to configuration settings from files and command-line overrides. The system supports hierarchical configuration with defaults, user preferences, and runtime overrides.

Sources

Configuration values are loaded from multiple sources in priority order:

1. Built-in defaults (lowest priority)

2. System-wide configuration files

3. User-specific configuration files

4. Command-line overrides (highest priority)

Sources

Settings are organized into logical categories:

• GENERAL: Basic application behavior

• EXTRACT: Data extraction parameters

• JOB_CHECKER: Job status checking options

• PERFORMANCE: Threading and resource limits

• OUTPUT: Formatting and display preferences

Organization

Configuration files use a simple key=value format with:

• Comments starting with # character

• Section headers for organization

• Type-safe value conversion and validation

• Support for various data types (string, int, double, bool)

Safety

The configuration system is designed for single-threaded initialization followed by read-only access from multiple threads. Write operations during runtime are supported but should be used carefully in multi-threaded environments.
