print ANSI_escape(31, 'Hello World');     # 31 is red

strip_ANSI_escapes($text)

Top Close Open

This function removes any ANSI escapes from the text passed as an argument.

ANSI

Top Close Open

This is an export hook which allows you to import subroutines which apply the correct ANSI escape codes to render text in colour on compatible terminals.

use Badger::Rainbox ANSI => 'red green blue';

print red("This is red");
print green("This is green");
print blue("This is blue");

Available colours are: black, red, green, yellow, blue, magenta, cyan and white. The bold and dark styles can also be specified.

use Badger::Rainbox ANSI => 'dark bold red green blue';

print bold red "Hello World\n";
print dark blue "Hello Badger\n";

Colours and styles can be specified as a single whitespace-delimited string or as a reference to a list of individual items.

use Badger::Rainbox ANSI => 'red green blue';
use Badger::Rainbox ANSI => ['red', 'green', 'blue'];
