Module shell 

Interactive PTY bridge: the local terminal driven against a pty exec.

The exec RPC, output ring, and resize/stdin calls live in crate::exec; this module owns the terminal-facing half: putting the local TTY in raw mode, forwarding raw keystrokes (so the guest’s line discipline turns Ctrl-C/Ctrl-D into signals), pumping merged output, propagating SIGWINCH as a resize, and restoring the terminal on exit.

Sailbox::shell is the high-level entry; the CLI drives run_interactive directly for its --tty flows. Unix-only: on other platforms the calls return an unsupported error and the build still succeeds.

Functions

run_interactive

Drive the local terminal against a PTY exec until the remote process exits, returning its exit code. Raw mode and the SIGWINCH handler are always restored, even on error.

stdio_is_tty

True when stdin and stdout are both TTYs, required for an interactive PTY.

terminal_size

The local terminal size as (cols, rows), defaulting to 80x24.
