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. --- Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index b7fe95d..62401b3 100644 --- a/Makefile +++ b/Makefile @@ -20,7 +20,7 @@ $(BUILD)/%.o: src/%.asm | $(BUILD) # C programs: compiled with SDCC into ROM-bank blobs and INCBIN'd by programs.asm CBLOBS := c/chello.bin c/echo.bin c/true.bin c/false.bin c/uname.bin \ c/pid.bin c/cat.bin c/wc.bin c/head.bin c/args.bin \ - c/ls.bin c/save.bin c/rm.bin c/sh.bin c/ps.bin c/kill.bin c/spin.bin c/blk.bin c/mkdir.bin + c/ls.bin c/save.bin c/rm.bin c/sh.bin c/ps.bin c/kill.bin c/spin.bin c/blk.bin c/mkdir.bin c/count.bin $(BUILD)/programs.o: $(CBLOBS) # C programs also depend on the shared libc sources -- cgit v1.3.1-sl0p
