DESCRIPTION

CONFIGURATION

stderr

Bool, default 1. Whether to print to STDERR (the default) or STDOUT.

use_color

Bool. The default is to look at the NO_COLOR and COLOR environment variables, or 1 when in interactive mode and 0 when not in interactive mode.

color_depth

Integer, either 0, 16, 256, or 16777216. If unset, will use the following heuristic to guess color depth of terminal. First, if "use_color" is false then 0. Otherwise, check if COLORTERM environment variable is defined and has the value of truecolor; if yes then use 16777216. Otherwise, check if TERM environment variable contains the string 256color; if yes then 256. Otherwise 16.

formatter

Coderef. When defined, will pass the formatted message (but being applied with colors) to this custom formatter.

ENVIRONMENT

NO_COLOR

Can be set (to anything) to disable color by default, if /use_color is not set. Consulted before "COLOR".

COLOR

Can be set to disable/enable color by default, if /use_color is not set.
