Use init_extended_pair/init_extended_color/extended_color_content/ extended_pair_content when available (ncurses 6+), removing the 256 color pair limitation. Window#color_set is upgraded to use wattr_set internally when available, allowing pair numbers > 255. New methods: - Curses.support_extended_colors? — runtime check for extended support - Curses.reset_color_pairs — reset all pairs to undefined (ncurses 6.1+) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
When Curses.support_extended_colors? returns true, display up to 512 color pairs (capped at color_pairs) using stdscr.color_set instead of attrset(color_pair()), since COLOR_PAIR() cannot encode pair numbers > 255. Pairs 256-511 use a dark grey background to distinguish them from the first 256. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- curses_color_content, curses_pair_content: check return value of extended_color_content/color_content/extended_pair_content/pair_content and return nil on ERR instead of returning uninitialized values - curses_reset_color_pairs: add curses_stdscr() call for consistency with other color APIs - window_color_set: use wattr_get to preserve existing window attributes when calling wattr_set; use NCURSES_PAIRS_T for the pair argument to match the ncurses header type in both standard and extended modes; fall back to wattr_set without attr preservation if wattr_get is unavailable, and to wcolor_set if wattr_set is also unavailable - extconf.rb: add have_func check for wattr_get - sample/colors.rb: skip pair 0 (cannot be redefined); use i%colors instead of i%256 to handle terminals with fewer than 256 colors Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
NCURSES_PAIRS_T is ncurses-specific and not defined in PDCurses. Fall back to short when it is not available. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Support ncurses extended colors API
These wrap wattr_set() and wattr_get() respectively, exposing the full extended color pair number (> 255) that attrset/color_set cannot represent. attr_set(attrs, pair) sets both attributes and color pair; attr_get returns [attrs, pair] as a 2-element Array. Both are guarded by HAVE_WATTR_SET / HAVE_WATTR_GET and fall back to rb_f_notimplement when unavailable. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- attr_set: NUM2ULONG -> NUM2UINT to match attr_t (unsigned int) - attr_get: ULONG2NUM -> UINT2NUM for attr_t; INT2FIX -> INT2NUM for pair number to safely handle extended pair values on all platforms Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add Window#attr_set and Window#attr_get
Do not use wattr_set() if wattr_get() is unavailable
To check easily whether these functions are available.
Do not use rb_f_notimplement for attr_set/attr_get
