	the terminal's foreground or background colour as 0xRRGGBB, asked with OSC 10/11 and read back from the answer; 0 where nothing answers within 150 ms
static bool	dark ()
	the terminal's background, probed once at the first themed output

Member Data Documentation

headless

bool dx::tty::headless {}

inlinestatic

nobody attends the process (dx::process::headless()): no terminal is queried - its reply would never come
