Add the X/Open Curses SCREEN API for driving more than one terminal: newterm() and set_term(), plus the ncurses extension new_prescr(). A new screen object wraps the C SCREEN. It exposes the terminal's standard window as screen.stdscr. Each window keeps a reference to its screen (like a subwindow does to its parent window), so the screen is deleted automatically once it and all of its windows are unreferenced. The ncurses use_screen()/use_window() locking helpers are exposed as the screen.use() and window.use() methods. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Add the X/Open Curses SCREEN API for driving more than one terminal:
curses.newterm()andcurses.set_term(), plus the ncurses extensioncurses.new_prescr().A new
screenobject wraps the CSCREENand exposes the terminal's standard window asscreen.stdscr. Each window keeps a reference to its screen (like a subwindow does to its parent window), so a screen is freed automatically once it and all of its windows are unreferenced.delscreen()is deferred to the screen object's deallocation rather than itstp_clear, so it runs only after the screen's windows — and any panels built on them — are gone.The ncurses
use_screen()/use_window()locking helpers are exposed as thescreen.use()andwindow.use()methods, forwarding*argsand**kwargsto the callable.ScreenTestsnow run in-process over pseudo-terminals instead of subprocesses, andTestCursesdrives anewterm()screen, so the new API is exercised without needing a second real terminal.🤖 Generated with Claude Code
