About:
Indicators is a header-only C++ library for creating flexible and customizable progress bars and activity indicators in terminal applications. It provides a rich set of configurable components like progress bars, spinners, and dynamic displays that can be easily integrated into any C++ project. The library is designed with a modern, non-blocking API to provide clear visual feedback for long-running operations without hindering application performance.

Key Features:

Header-only library for easy integration
Highly customizable with various styles and themes
Thread-safe and non-blocking operations
Supports multiple indicator types (progress bars, spinners, etc.)

Use Cases:

Adding progress bars to command-line tools
Visualizing long-running computations or data processing
Providing real-time feedback in server applications

Alternatives:

indicators-cpp – This is the primary and most popular library for this purpose in modern C++.
ncurses – A much lower-level library for terminal manipulation, requiring more boilerplate for simple indicators.
