From e9a910b33c7837b4b868e3abda18eb4810df7f02 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 4 Oct 2025 09:14:33 +0100 Subject: config/git: import suckless sbase i currently use the output of sha512sum in several places of xbmk, which is a bit unreliable in case output changes. other cases where i use util outputs in variables are probably reliable, because i'm using mostly posix utilities in those. to mitigate this, i now import suckless sbase, which has a reasonable sha512sum implementation. *every* binary it builds is being placed in build.list, because i'll probably start using more of them. for example, i may start modifying the "date" implementation, adding the GNU-specific options that i need as mentioned on init.sh i'm importing it in util/ because the sha512sum util is needed for verifying project sources, so if sbase itself is a "project source", that means we can into a chicken and egg bootstrapping problem. this is sbase at revision: 055cc1ae1b3a13c3d8f25af0a4a3316590efcd48 Signed-off-by: Leah Rowe --- util/sbase/libutil/eprintf.c | 57 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 util/sbase/libutil/eprintf.c (limited to 'util/sbase/libutil/eprintf.c') diff --git a/util/sbase/libutil/eprintf.c b/util/sbase/libutil/eprintf.c new file mode 100644 index 00000000..7197fbb9 --- /dev/null +++ b/util/sbase/libutil/eprintf.c @@ -0,0 +1,57 @@ +/* See LICENSE file for copyright and license details. */ +#include +#include +#include +#include + +#include "../util.h" + +char *argv0; + +void +eprintf(const char *fmt, ...) +{ + va_list ap; + + va_start(ap, fmt); + xvprintf(fmt, ap); + va_end(ap); + + exit(1); +} + +void +enprintf(int status, const char *fmt, ...) +{ + va_list ap; + + va_start(ap, fmt); + xvprintf(fmt, ap); + va_end(ap); + + exit(status); +} + +void +weprintf(const char *fmt, ...) +{ + va_list ap; + + va_start(ap, fmt); + xvprintf(fmt, ap); + va_end(ap); +} + +void +xvprintf(const char *fmt, va_list ap) +{ + if (argv0 && strncmp(fmt, "usage", strlen("usage"))) + fprintf(stderr, "%s: ", argv0); + + vfprintf(stderr, fmt, ap); + + if (fmt[0] && fmt[strlen(fmt)-1] == ':') { + fputc(' ', stderr); + perror(NULL); + } +} -- cgit v1.2.1
