ANSI Escape Code support library for Dart

Use ANSI Escape Codes to apply some formatting to your text.

Can easily be globally disabled, by setting AnsiColorizer.enableColorizers to false.

Example

import "package:ansi_colorizer/ansi_colorizer.dart";

void main() {
  // Create an AnsiColorizer object with your specific formatting options.
  const colorizer = AnsiColorizer(
    foreground: Ansi24BitColor.fromRGB(210, 200, 0),
    modifiers: {
      AnsiModifier.bold,
      AnsiModifier.italic,
    },
  );

  // Apply the formatting to the string representation of an object
  // by calling using the colorizer variable like a function.
  //
  // Alternatively you can also use:
  // final result = colorizer.colorize("Hello World");
  final result = colorizer("Hello World");

  // Prints "Hello World", but the text color is yellow and the
  // text is bold and cursive.
  print(result);
}

Colors

This library supports 8 bit and 24 bit colors.

8 Bit

This table represents all available colors.

table

...
// The standard color for red (see the color table).
final color = Ansi8BitColor(1);
...

24 Bit

Create a color from a red, green and blue component.

...
final red = Ansi24BitColor(0xFF0000);
final green = Ansi24BitColor.fromRGB(0, 0xFF, 0);
...

Modifiers

You can also apply a modifier from the AnsiModifier enum to make your text bold for example.
