Mmm, I thought it was well-known, but apparently not :/
I mean using this (see terminfo(5) for the details):
#include <term.h>
#include <stdio.h>
#include <unistd.h>
int main(void) {
int my_bg_color = 0;
int my_fg_color = 4;
setupterm(NULL, STDOUT_FILENO, NULL);
tputs(enter_bold_mode, 1, putchar);
tputs(enter_italics_mode, 1, putchar);
tputs(enter_underline_mode, 1, putchar);
tputs(enter_blink_mode, 1, putchar);
tputs(enter_reverse_mode, 1, putchar);
tputs(tparm(set_a_foreground, my_fg_color), 1, putchar);
tputs(tparm(set_a_background, my_bg_color), 1, putchar);
printf("Hello, world!\n");
tputs(exit_attribute_mode, 1, putchar);
return 0;
}
On terminals which support it, you can even get rgb colors by using
initialize_color or initialize_pair. If you want a more complete
example, see lstopo-text.c inside the hwloc package, we include ncurses,
but we don't actually need it for this kind of code. Try with
lstopo -.txt
Doing it really properly as exampled above doesn't look terribly
overengineered to me.
