Components

vt-parser/

VT100/xterm escape sequence parser. Handles:

• CSI (Control Sequence Introducer) — cursor movement, erase, scroll, SGR attributes
• OSC (Operating System Command) — window title, clipboard, hyperlinks
• DCS (Device Control String) — device-specific sequences

pty/

PTY management with platform-specific backends:

• Unix (macOS/Linux) — POSIX PTY via openpty/forkpty
• Windows — ConPTY for modern terminal support

Spawns shell processes and manages bidirectional I/O between the emulator and the child process.

input/

Input encoding layer:

• Key encoder — maps keyboard events to VT escape sequences
• Mouse encoder — translates mouse events to xterm mouse reporting sequences

emulator.ts

Terminal emulator core. Ties together the parser, screen buffer, and input handler into a unified terminal instance. Manages:

• Screen buffer (primary and alternate)
• Cursor state and attributes
• Scroll region and scrollback
• Character set handling

Rendering

Cross-platform rendering via Rust FFI, following the same pattern as hone-editor’s native layer. The TypeScript emulator owns the terminal state; Rust handles platform-specific drawing.
