COLOR.4TH(7) Standards, Environments, and Macros COLOR.4TH(7)

NAME


color.4th - loader color-detection boot module

DESCRIPTION


The file that goes by the name of color.4th is a set of commands designed
to simplify color logic. The commands of color.4th by themselves are not
enough for most uses. Please refer to the examples below for the most
common situations, and to loader(7) for additional commands.

Before using any of the commands provided in color.4th, it must be included
through the command:

include color.4th

This line is present in /boot/forth/loader.4th file, so it is not needed
(and should not be re-issued) in a normal setup.

The commands provided by it are:

loader_color? Returns FALSE if the loader_color environment
variable is set to "NO" (case-insensitive) or
"0". Otherwise returns TRUE (unless booting
serial).

The environment variables that effect its behavior are:

loader_color
If set to "NO" (case-insensitive) or "0", causes
loader_color? to return FALSE, indicating to many modules
that color should not be used.

FILES


/boot/loader The loader(7).
/boot/forth/color.4th color.4th itself.
/boot/loader.rc loader(7) bootstrapping script.

EXAMPLES


Standard i386 /boot/loader.conf:

Use color where applicable:

loader_color="YES"
