console 4.1.0

A library for common features required by console applications, including color formatting, keyboard input, and progress bars.

Console

A high-level console library.

Features

• Console Colors (ANSI)
• Icons (UTF-8)
• Keyboard Capture
• Experimental Clipboard Support
• Progress Bars
• Flexible Prompts
• Shell Prompts
• Choosers
• Fancy Formatting
• Loading Bars
• Timer (like pub's timer)
• Fancy Trees (like the npm dependency trees)
• Simple Unit Testing

Usage

This library does not work in browsers (for a hopefully obvious reason).

import "package:console/console.dart";

void main() {
  // Initialize the Console. Throws an exception if advanced terminal features are not supported.
  Console.init();
  
  // Use the library...
}

Unit Testing

You can test the output produced by this library (and thus your own project that uses this library). Here is an example:

import "package:test/test.dart";
import "package:console/console.dart";

void main() {
  final output = new BufferConsoleAdapter();

  setUpAll(() => Console.adapter = output);

  // Clear output between test runs
  setUp(() => output.clear());

  group('base functions', () {
    test('centerCursor', () {
      Console.centerCursor();
      expect(output.toString(), '${Console.ANSI_ESCAPE}10;40H');
    });
  });
}
