gbos.git/c/count.c, branch mastergbos - a tiny Unix-flavored OS for the Game Boy Color (kernel, shell, coreutils in C, RAM filesystem)https://git.sl0p.foo/gbos.git/atom/c/count.c?h=master2026-07-17T22:38:38Zrefactor: c/ -> usr/, compiled program blobs out of the source tree2026-07-17T22:38:38Zuseruser@clank2026-07-17T22:38:38Zurn:sha1:ba2d7ae1d7b319645b10aaa31a7f664f9f80c25c
Userland sources live in usr/ (fits the Unix theme better than 'c').
SDCC output .bin blobs land in build/usr/ with the other build artifacts
instead of littering the source dir; programs.asm INCBINs them from there.
Byte-identical ROM.
term/osk: scroll region so the OSK never hides the input line2026-07-16T14:30:33Zuseruser@clank2026-07-16T14:30:33Zurn:sha1:fe51f65be393161da81d6db6144418c97a8e0fe7
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.
