vtcode-ghostty-core

Pure-Rust VT terminal emulator core for VT Code, inspired by Ghostty's terminal design.

vtcode-ghostty-core processes VT byte streams incrementally via Terminal::write, maintaining a cell-based screen buffer with cursor state, styling, and terminal modes.

Modules

Module	Purpose
`cell`	`Cell` type representing a single character cell with style and content
`color`	`AnsiColor` and `Color` types for terminal color representation
`cursor`	`Cursor` type tracking position, shape, and visibility
`mode`	`CursorShape` and `MouseTracking` enums for terminal mode flags
`screen`	`ScreenKind` enum and screen buffer management
`style`	`Style` type for cell-level styling (fg, bg, effects)
`parser` (private)	VT escape sequence parser
`region` (private)	Scroll region management
`terminal` (private)	`Terminal` implementation orchestrating parser, screen, and cursor

Public entrypoints

Terminal — main terminal emulator; call write(bytes) to process VT input
Cell — character cell with content and style
Cursor — cursor position and shape state
Color / AnsiColor — terminal color types
Style — cell styling (foreground, background, effects)
CursorShape / MouseTracking — terminal mode enums
ScreenKind — screen buffer type

Usage

use vtcode_ghostty_core::Terminal;

let mut terminal = Terminal::new(80, 24);
terminal.write(b"Hello, World!\r\n");
terminal.write(b"\x1b[1;31mBold Red\x1b[0m");
