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($string) | uncolour($string)
      my $stripped = uncolor($colored_data);
      my @no_color = uncolor(\@colored);
      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() | get_colours()
      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()".
