num_colors {crayon} | R Documentation |
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.
