letui

demo.mp4

Simple TUI library written using Rust and TypeScript

Core dependencies:

• crossterm - cross-platform terminal manipulation library
• taffy - UI layout engine

TODO:

• Hover support
• Try to optimizatize the shit out of everything
• Add logging and debugging utilities
• Improve overall architecture ("make it work" is done, now "make it right, make it fast" is left)
• Refactor flush function with BatchWriter pattern to reduce nesting
  • BatchWriter struct holds stdout ref, char_seq, batch_start_x/y, prev_fg/bg
  • new() initializes with sentinel colors (u64::MAX) to force first color emit
  • push(x, y, ch, fg, bg) handles gap detection, color changes, and accumulates chars
  • flush_pending() emits MoveTo + Print for accumulated batch
  • Encapsulates all batching logic, main loop just calls push() for changed cells
• Add scrollable containers
• Add performance stats overlay that update independently from rest of the app (can i use a separate thread?)
