ccstatusline is a CLI status bar framework and ANSI terminal UI library used to render dynamic, multi-line interfaces within terminal emulators. It functions as a customizable system for displaying real-time metrics, system data, and configuration settings through a widget-based composition model.
The framework specializes in Powerline-style status lines, utilizing arrow separators and columnar alignment to create structured headers. It includes specialized dashboards for monitoring Git repository metadata, such as branch names and commit IDs, as well as LLM usage monitors that track API token consumption, session costs, and prompt cache hit rates.
The library handles visual styling via hex colors and ANSI gradients, while managing responsive layouts through dynamic terminal width detection. It employs a state-driven layout system to organize, reorder, or hide modular widgets based on active data and periodic poll-based refreshes.
