More Dart  Literally
Various extensions that make Dart a better place:
bit_list.dart
is a space efficient list storing boolean values.char_matcher.dart
is a model for character classes, their composition and operations on strings.fraction.dart
provides exact rational number arithmetic.int_math.dart
is a collection of common mathematical functions on integers.iterable.dart
is a collection of iterables and iterators.multiset.data
a data structure where elements might appear more than once.ordering.dart
a fluent interface for building comparator functions.range.dart
is a function to create lists of arithmetic progressions.
And there is more to come ...
This library is open source, stable and well tested. Development happens on GitHub. Feel free to report issues or create a pullrequest there. General questions are best asked on StackOverflow.
Continuous build results are available from Jenkins. Uptodate documentation is created automatically with every new push.
Basic Usage
Installation
Add the dependency to your package's pubspec.yaml file:
dependencies:
more: ">=1.0.0 <2.0.0"
Then on the command line run:
$ pub get
To use one or more of the packages in your Dart code write:
import 'package:more/bit_list.dart';
import 'package:more/char_matcher.dart';
import 'package:more/fraction.dart';
import 'package:more/int_math.dart';
import 'package:more/iterable.dart';
import 'package:more/multiset.dart';
import 'package:more/ordering.dart';
import 'package:more/range.dart';
Misc
History
This library started in April 2013 as I was working through the puzzles of Project Euler and encountered some missing features in Dart. Over time the library grew and became more useful in many other places, so I created this reusable library.
