TERM ¶ The environment variable TERM contains a identifier for the text
window’s capabilities. You can get a detailed list of these cababilities
by using the ‘infocmp’ command (for example: infocmp -L1 xterm),
using ‘man 5 terminfo’ as a reference.
When producing text with embedded color directives, a
libtextstyle-enabled program looks at the TERM variable.
Text windows today typically support at least 8 colors. Often, however,
the text window supports 16 or more colors, even though the TERM
variable is set to a identifier denoting only 8 supported colors. It
can be worth setting the TERM variable to a different value in
these cases.
After setting TERM, you can verify how well it works by invoking
‘program --color=test’, where program is any
libtextstyle-enabled program, and seeing whether the output looks
like a reasonable color map.
