From fe51f65be393161da81d6db6144418c97a8e0fe7 Mon Sep 17 00:00:00 2001 From: user Date: Thu, 16 Jul 2026 16:30:33 +0200 Subject: term/osk: scroll region so the OSK never hides the input line The terminal now has a variable usable height (wTermRows). term_scroll and cursor_down operate within [0 .. wTermRows-1], and term_set_rows(n) shrinks or grows that region, scrolling the cursor up into view when it would fall outside. osk_toggle shrinks the terminal to the rows above the keyboard on show (18 - OSK_ROWS = 15) and restores full height on hide, so the active line is always visible just above the docked keyboard, and hiding the OSK reclaims all 18 rows. Also add c/count.c ("count [n]", default 25): prints n numbered lines to observe/debug scrolling and the scroll-region behavior. Registered as program id 21 / bank 23. Fixed the arg to read argv[0] (getargs returns the string after the command name). Verified: filling the screen then opening the OSK scrolls the latest line to row 14 (visible) with the keyboard at 15-17; closing it restores rows 15-17; count N prints exactly N lines. --- c/count.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 c/count.c (limited to 'c/count.c') diff --git a/c/count.c b/c/count.c new file mode 100644 index 0000000..37cdcce --- /dev/null +++ b/c/count.c @@ -0,0 +1,16 @@ +#include "gbos.h" +/* count [n]: print n numbered lines (default 25) to observe terminal scrolling + and the OSK scroll-region.
