6. Usage

6.1. Basic Usage

• Import composer's autoload.php at first.

  <?php
  
  require_once __DIR__ . '/../vendor/autoload.php';

• Displaying messages:

  static calls:

  use Macocci7\BashColorizer\Colorizer;
  
  Colorizer::echo("Hi, there!");
  Colorizer::echo(" How's it going with you?", PHP_EOL);

  method chains:

  Colorizer::echo("Hi, there!");
      ->echo(" How's it going with you?", PHP_EOL);

  creating an instance:

  $colorizer = new Colorizer;
  $colorizer->echo("Hi, there!")
      ->echo(" How's it going with you?", PHP_EOL);

• Configuration:

  static call:

  $config = [
      'attributes' => ['italic', 'bold'],
      'foreground' => 'black',
      'background' => 'green',
  ];
  
  Colorizer::config($config);
  Colorizer::echo("Hi, there!");

  method chain:

  Colorizer::config($config)
      ->echo("Hi, there!");

  creating an instance:

  // several ways
  $colorizer = new Colorizer;
  $colorizer = new Colorizer($config);
  $colorizer = Colorizer::config($config);
  
  $colorizer->config($config)
      ->echo("Hi, there!")
      ->echo(" How's it going with you?", PHP_EOL);

• Setting attributes:

  Colorizer::attributes(['underline', 'strike'])
      ->echo("Hi, there!", PHP_EOL);

  See more: Available Attributes

• Setting foreground color:

  by name:

  Colorizer::foreground('green')
      ->echo("Hi, there!", PHP_EOL);

  by hex code:

  Colorizer::foreground('#ffcc00')  // or #fc0
      ->echo("Hi, there!", PHP_EOL);

  by number [0 - 255] (256 colors):

  Colorizer::foreground(2)
      ->echo("Hi, there!", PHP_EOL);

  by (RGB) array (24bit 16777216 colors):

  Colorizer::foreground([0, 255, 0])
      ->echo("Hi, there!", PHP_EOL);

  See more: Available Colors

• Setting background color:

  by name:

  Colorizer::background("red")
      ->echo("Hi, there!", PHP_EOL);

  by hex code:

  Colorizer::background("#ffcc00")  // or #fc0
      ->echo("Hi, there!", PHP_EOL);

  by number [0 - 255] (256 colors):

  Colorizer::background(1)
      ->echo("Hi, there!", PHP_EOL);

  by (RGB) array (24bit 16777216 colors):

  Colorizer::background([255, 0, 0])
      ->echo("Hi, there!", PHP_EOL);

  See more: Available Colors

• Equivalent to config():

  Colorizer::attributes(['double-underline', 'italic'])
      ->foreground("yellow")
      ->background("blue")
      ->echo("Hi, there!", PHP_EOL);

• Setting underline color:

  by hex code:

  Colorizer::underline("#ffcc00")  // or #fc0
      ->echo("Hi, there!", PHP_EOL);

  by number [0 - 255] (256 colors):

  Colorizer::underline(1)
      ->echo("Hi, there!", PHP_EOL);

  by (RGB) array (24bit 16777216 colors):

  Colorizer::underline([255, 0, 0])
      ->echo("Hi, there!", PHP_EOL);

  See more: Available Colors

• Returning colorized string:

  As an argument of echo:

  echo Colorizer::config($config)
      ->encode("Hi, there!") . PHP_EOL;

  This is also effective:

  echo sprintf(
      "%s: %s%s",
      $name,
      Colorizer::config($config)
          ->encode("Hi, there!"),
      PHP_EOL
  );

• Returning human readable encoded string:

  echo Colorizer::attributes(["bold"])
      ->background([255, 255, 0])
      ->foreground([0, 128, 255])
      ->readable('Hi, There!', PHP_EOL);

  This code outputs the following string:

  \033[1;38;2;0;128;255;48;2;255;255;0mHi, there!\033[m

  Running bash command echo with -e option on this string takes colorizing effect:

  bash-$ echo -e '\033[1;38;2;0;128;255;48;2;255;255;0mHi, there!\033[m'
