Tview
tview is a library for building interactive text-based user interfaces in Go. It functions as a toolkit for managing event loops, user input, and screen rendering, providing a framework of pre-built widgets and an integrated layout engine for creating command-line applications.
The project distinguishes itself through a comprehensive layout system that uses grid and flexbox models to create responsive designs. It also supports UI layer stacking to manage multiple screens and modal overlays.
The framework includes a diverse suite of interactive components for data display, such as tables and hierarchical tree views, as well as input forms featuring text fields, checkboxes, and autocomplete suggestions. Visual capabilities extend to Unicode box-drawing, inline text styling for colors and attributes, and the rendering of images via pixel approximation and dithering.
