Add window methods and module functions that report curses state which could previously only be set: the window getters is_cleared(), is_idcok(), is_idlok(), is_immedok(), is_keypad(), is_leaveok(), is_nodelay(), is_notimeout(), is_pad(), is_scrollok(), is_subwin(), is_syncok(), getdelay(), getparent() and getscrreg(), and the functions is_cbreak(), is_echo(), is_nl() and is_raw(). They are available when built against an ncurses with NCURSES_EXT_FUNCS. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

These four functions were added in ncurses 6.5; guarding them with the same NCURSES_EXT_FUNCS >= 20110404 as the window getters broke the build on older ncurses (e.g. macOS, which ships 6.0). Require NCURSES_EXT_FUNCS >= 20240427. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The new window state-query methods grew PyCursesWindow_methods[] past the default 200-line limit, crashing check-c-globals. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Thank you for noticing. They are terminal depending. I forgot to run these tests on different terminals. #152304 should fix the test. |

Wrap the ncurses "opaque" accessors that report curses state which the standard API can only set, never read back.
New window methods:
is_cleared,is_idcok,is_idlok,is_immedok,is_keypad,is_leaveok,is_nodelay,is_notimeout,is_scrollokandis_syncokreturn the value set by the matching setter.is_padandis_subwinreport the kind of window.getdelay()returns the read timeout in milliseconds (as set bynodelay()/timeout()).getscrreg()returns the current scrolling region as a(top, bottom)tuple.getparent()returns the parent window, orNoneif the window is not a subwindow.New module functions:
is_cbreak,is_echo,is_nlandis_rawreport the current terminal mode set bycbreak,echo,nlandraw.All of these are available only when Python is built against an ncurses with
NCURSES_EXT_FUNCS(ncurses 5.9 and later).🤖 Generated with Claude Code
