NAME

Term::ANSIColor::Conditional - Colorize text only if color is enabled

VERSION

This document describes version 0.009 of Term::ANSIColor::Conditional (from Perl distribution Term-ANSIColor-Conditional), released on 2021-06-01.

SYNOPSIS

Use as you would Term::ANSIColor.

DESCRIPTION

This module is a wrapper for Term::ANSIColor. If color is enabled then everything is the same as Term::ANSIColor. If color is disabled, then color() will emit empty string and colored() will not colorize input text.

How to determine "color is enabled":

  • If package variable $Term::ANSIColor::Conditional::COLOR is defined, use that.

  • Otherwise, check if NO_COLOR environment variable exists. If yes, color is disabled.

  • Otherwise, check if COLOR environment variable is defined and use that.

  • Otherwise, check if (-t STDOUT) is true (interactive terminal). If yes, color is enabled.

  • Otherwise, color is disabled.

Note that Term::ANSIColor already supports conditional color via the ANSI_COLORS_DISABLED and NO_COLOR environment variables, but it does not check for interactive terminal or the COLOR environment variable.
