NAME

Acme::CPANModules::COLOR - Modules that follow the COLOR & NO_COLOR convention

VERSION

This document describes version 0.003 of Acme::CPANModules::COLOR (from Perl distribution Acme-CPANModules-COLOR), released on 2021-03-27.

DESCRIPTION

The NO_COLOR convention (see https://no-color.org) lets user disable color output of console programs by defining an environment variable called NO_COLOR. The existence of said environment variable, regardless of its value (including empty string, undef, or 0), signals that programs should not use colored output.

Another similar convention is the use of the COLOR environment variable. False value (empty string or the value 0) means that programs should disable colored output, while true value (values other than the mentioned false values) means that programs should enable colored output. This convention allows force-enabling colored output instead of just force-disabling it, although programs supporting it need to add a line of code or two to check the value of the environment variable.

If you know of other modules that should be listed here, please contact me.
