NAME
Term::ExtendedColor - Color screen output using 256 colors
SYNOPSIS
use Term::ExtendedColor qw(:all);
# Or use the 'attributes' tag to only import the functions for setting
# attributes.
# This will import the following functions:
# fg(), bg(), bold(), underline(), inverse(), italic(), clear()
use Term::ExtendedColor ':attributes';
## Foreground colors
my $red_text = fg('red2', 'this is in red');
my $spring = fg('springgreen3', 'this is green');
## Background colors
print bg('red5', "Default foreground text on dark red background"), "\n";
my $red_on_green = fg('red3', bg('green12', 'Red text on green background'));
print "$red_on_green\n";
## Fall-through attributes
Term::ExtendedColor::autoreset(0);
my $bold = fg('bold', 'This is bold');
my $red = fg('red2', 'This is red... and bold');
my $green = bg('green28', 'This is bold red on green background');
# Make sure to clear all attributes when autoreset turned OFF,
# or else the users shell will be messed up
my $clear = clear();
print "$bold\n";
print "$red\n";
print "$green $clear\n";
## Non-color attributes
# Turn on autoreset again
Term::ExtendedColor::autoreset(1);
for(qw(italic underline blink reverse bold)) {
print fg($_, $_), "\n";
}
# For convenience
my $bolded = bold("Bold text!");
my $italic = italic("Text in italics!");
## Remove all attributes from input data
my @colored;
push(@colored, fg('bold', fg('red2', 'Bold and red')));
push(@colored, fg('green13', fg('italic', 'Green, italic')));
print "$_\n" for @colored;
print "$_\n" for uncolor(@colored);
DESCRIPTION
Term::ExtendedColor provides functions for sending so called extended escape sequences to
the terminal. This ought to be used with a 256-color compatible terminal; see the NOTES
section for a matrix of terminal emulators currently supporting this.
EXPORTS
None by default.
Two tags are provided for convience:
# Import all functions
use Term::ExtendedColor qw(:all);
# Import functions for setting attributes
# fg(), bg(), bold(), italic(), underline(), inverse(), clear()
use Term::ExtendedColor qw(:attributes);
FUNCTIONS
fg($color, $string)
my $green = fg('green2', 'green foreground');
my @blue = fg('blue4', ['takes arrayrefs as well']);
my $x_color = fg('mediumorchid1', 'Using mappings from the X11 rgb.txt');
my $arbitary_color = fg(4, 'This is colored in the fifth ANSI color');
Set foreground colors and attributes.
See "COLORS AND ATTRIBUTES" for valid first arguments. Additionally, colors can be
specified using their index value:
my $yellow = fg(220, 'Yellow');
If the internal $AUTORESET variable is non-zero (default), every element in the list of
strings will be wrapped in escape sequences in such a way that the requested attributes
will be set before the string and reset to defaults after the string.
Fall-through attributes can be enabled by setting $AUTORESET to a false value.
Term::ExtendedColor::autoreset( 0 );
my $red = fg('red1', 'Red');
my $green = fg('green1', 'Green');
print "Text after $red is red until $green\n";
print "Text is still green, ", bold('and now bold as well!');
# If you exit now without resetting the colors and attributes, chances are
# your prompt will be messed up.
clear(); # All back to normal
If an invalid attribute is passed, the original data will be returned unmodified.
bg($color, $string)
my $green_bg = bg('green4', 'green background');
my @blue_bg = bg('blue6', ['blue background']);
Like "fg()", but sets background colors.
uncolor($string)
my $stripped = uncolor($colored_data);
my @no_color = uncolor(\@colored);
Remove all attribute and color escape sequences from the input.
See uncolor for a command-line utility using this function.
get_colors()
my $colors = get_colors();
Returns a hash reference with all available attributes and colors.
clear()
When called in scalar context, returns the escape sequence that resets all attributes to
their defaults.
When called in void context, prints it directly.
autoreset()
Turn autoreset on/off. Enabled by default.
Term::ExtendedColor::autoreset( 0 ); # Turn off autoreset
bold(@data)
Convenience function that might be used in place of "fg('bold', @data)";
italic(@data)
Convenience function that might be used in place of "fg('italic', @data)";
underline(@data)
Convenience function that might be used in place of "fg('underline', @data)";
inverse(@data)
Reverse video / inverse. Convenience function that might be used in place of
"fg('inverse', @data)";
NOTES
The codes generated by this module complies to the extension of the ANSI colors standard
first implemented in xterm in 1999. The first 16 color indexes (0 - 15) is the regular
ANSI colors, while index 16 - 255 is the extension. Not all terminal emulators support
this extension, though I've had a hard time finding one that doesn't. :)

* Previously needed a patch. Full support was added in version 9.09.
There's no way to give these extended colors meaningful names.
Our first thought was to map them against some standard color names, like those in the
HTML 4.0 specification or the SVG one. They didn't match.
Therefore, they are named by their base color (red, green, magenta) plus index; The first
index (always 1) is the brightest shade of that particular color, while the last index is
the darkest.
It's also possible to use some X color names, as defined in "rgb.txt". Do note that the
color values do not match exactly; it's just an approximation.
A full list of available colors can be retrieved with "get_colors()". See "COLORS AND
ATTRIBUTES" for full list. All mapped colors can also be retrieved programmatically with
"get_colors()".
