gbos.git/c/false.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/false.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.
libc + CLI tools: a small C userland2026-07-16T05:21:40Zuseruser@clank2026-07-16T05:21:40Zurn:sha1:4335d248d18987a050d8ac26965c90718eef7562
- libc: add putc, puts, strlen, getargs (args string), EOF (=4) for readc.
- args: shell splits the command line at the first space ("cmd\0args\0" at
$A000, inherited by the child via fork); getargs() returns the arg string.
- shell: exit on Ctrl-D/EOF; $ prompt over a clean read loop.
- tools (c/): echo (argv), cat (stdin->stdout to EOF), uname, pid (decimal
print), true, false. Each built to a ROM-bank blob and registered.
- Makefile: CBLOBS list builds all C programs.
- README: document libc + the tool set.
