NAME

Terminal::ANSIColor - Color screen output using ANSI escape sequences

SYNOPSIS

use Terminal::ANSIColor;

say color('bold'), "this is in bold", color('reset');
say colored('what a lovely colours!', 'underline red on_green');
say BOLD, 'good to be fat!', BOLD_OFF;
say 'ok' if colorvalid('magenta', 'on_black', 'inverse');
say '\e[36m is ', uncolor('\e36m');
say colorstrip("\e[1mThis is bold\e[0m");

DESCRIPTION

Terminal::ANSIColor provides an interface for using colored output in terminals. The following functions are available:

color

Given a string with color names, the output produced by color() sets the terminal output so the text printed after it will be colored as specified. The following color names are recognised:

reset bold italic underline inverse
bold_off italic_off underline_off inverse_off
black red green yellow blue magenta cyan white
default on_black on_red on_green on_yellow
on_blue on_magenta on_cyan on_white on_default

The on_* family of colors correspond to the background colors. One or three numeric color values in the range 0..255 may also be specified:

N     # 256-color map: 8 default + 8 bright + 216 rgb cube + 24 gray
on_N  # Same, but background

N,N,N     # 24-bit r,g,b foreground color
on_N,N,N  # 24-bit r,g,b background color

colored

colored() is similar to color(). It takes two Str arguments, where the first is the string to be colored, and the second is the (space-separated) colors to be used. The reset sequence is automagically placed after the string.

colorvalid

colorvalid() gets an array of color specifications (like those passed to color()) and returns true if all of them are valid, false otherwise.

colorstrip

colorstrip, given a string, removes all the color escape sequences in it, leaving the plain text without color effects.

uncolor

Given escape sequences, uncolor() returns a string with readable color names. E.g. passing "\e[36;44m" will result in "cyan on_blue".

Constants

Terminal::ANSIColor provides constants which are just strings of appropriate escape sequences. The following constants are available:

RESET BOLD ITALIC UNDERLINE INVERSE
BOLD_OFF ITALIC_OFF UNDERLINE_OFF INVERSE_OFF
