This project is a framework for composing terminal interfaces through declarative styling and a grid-based layout engine. It provides a comprehensive toolkit for building responsive command-line applications by managing ANSI escape sequences, color profiles, and text rendering to ensure consistent visual output across different terminal environments.
The library distinguishes itself through its ability to automatically detect terminal capabilities and background themes, allowing it to adjust color schemes and downsample profiles for optimal readability. It utilizes a layered composition model that supports z-indexing and relative positioning, enabling the construction of complex, nested interfaces from individual styled components.
Beyond core styling, the toolkit includes utilities for rendering structured data such as tables and trees, as well as spatial hit testing for interactive elements. It handles the complexities of terminal display by calculating the visual width of multi-byte characters, managing text wrapping, and providing support for decorative borders and color gradients.
The library is designed for integration into Go-based command-line projects, offering a fluent API for defining immutable style objects and managing terminal output. It includes built-in support for legacy Windows console environments and provides tools for inspecting and debugging visual configurations.
