Crates License Tag Docs

A (very experimental) plugin for the Bevy engine which allows for rendering to a terminal window.

WARNING: I highly recommend using the kitty terminal emulator with this, not only due to the gpu-accelerated rendering, but also the implementation of the kitty protocol which enables the advanced input detection.

Features Include:

  • TerminalDisplay automatically sets up a correctly-formatted render texture
  • Post-process dithers colors to pure black and white, which are then printed as braille characters to the terminal
  • Responsiveness to terminal window resizing
  • TerminalInput resource which keeps track of pressed & released keys
  • Widget component for rendering ratatui TUI widgets
  • TerminalWidget trait for creating custom TUI widget components
  • Log redirection
