Number of colors the terminal supports
num_colors(forget = FALSE)
forget |
Whether to forget the cached result of the color check. |
We use the tput shell command to detect the
number of colors. If tput is not available,
but we think that the terminal supports colors, then
eigth colors are assumed.
For efficiency, num_colors caches its result. To
re-check the number of colors, set the forget argument to
TRUE.
Numeric scalar, the number of colors the terminal supports.
