neoansi

ANSI escape sequences and styling micro-library written in fluent/modern Dart.

This library provides minimal ANSI escape sequences and helpers for
working with ANSI text terminals and terminal emulators, in which
escape characters and embedded values are interpreted as commands.

For example, for terminals with 16-bit (256) color support:

Usage

import 'dart:io';

import 'package:neoansi/neoansi.dart';

void main() {
  AnsiSink.from(stdout)
    ..setForegroundColor(Ansi1BitColors.red)
    ..write('Hello ')
    ..setForegroundColor(Ansi1BitColors.green)
    ..setUnderlined()
    ..write('World')
    ..resetStyles()
    ..writeln('!');
}

Contributing

This package welcomes new issues and pull requests.

Changes or requests that do not match the following criteria will be rejected:

1. Common decency as described by the Contributor Covenant.

3. Adding platform-specific functionality.
4. A somewhat arbitrary bar of “complexity”, everything should be easy to use.

Inspiration

Some inspiration/motivational sources elsewhere in pub (Dart) packages:

• ansicolor
• ansi_escapes
• ansi_styles
• dart_console

Note from Matan: Many of these packages do an adequate job, but none of
them had quite the API I wanted, so like many before them, this library was
created. Use whatever makes the most sense to you!
