Overview ¶
Package fluint is a TUI engine for Go, built from scratch with focus on smooth animations, VFX, and a built-in UI kit.
This is the root package. See sub-packages for the actual implementation:
- internal/term: raw terminal I/O and escape sequence parsing
- internal/platform: OS-specific abstractions
- core/buffer: cell grid and double buffering (planned)
- core/diff: minimal changeset computation (planned)
- render/ansi: ANSI escape output (planned)
- anim: animation and easing (planned)
- layout: flexbox-like layout system (planned)
- widgets: UI kit with functional options API (planned)
