diff v0.5.0...v0.6.0

This major update of kt.dart add 10+ extension methods for KtMap and makes working with maps even easier.

Behavior Changes #

The properties KtList.list: List,KtSet.set: Set are now deprecated and KtMap.map: Map was removed. Those properties where used to convert kt.dart collections to dart collections. Instead use the new KtList.asList(): List, KtSet.asSet(): Set, KtMa.asMap(): Map methods. The old properties returned copies of the collections. The new as-methods return views of the original collections and reflect changes of the original data.

This breaking change was necessary because the property KtMap.map: Map<K, V> was conflicting with KtMap.map(MapEntry<K, V> -> R) : KtList<R> to map the entries to items of a KtList. Read about further details here.

If you have used properties to iterate over the collections using a for-loop you should now always use iter which is available for all kt.dart collections.

for (final element in listOf("a", "b", "c").iter) {
  print(element); 
}
for (final element in setOf("a", "b", "c").iter) {
  print(element); 
}
for (final p in mapFrom({1: "Bulbasaur", 2: "Ivysaur"}).iter) {
  print("${p.key} -> ${p.value}"); 
}

Breaking Changes #

#64 The class prefix of all collections has been changed from K to Kt (KList -> KtList)
#60 listOf now accepts up to 10 non-null arguments instead of an Iterable. Use listFrom to create KtLists from an dart Iterables
#60 Collections can now be created with factory constructors i.e. KtList.of(1, 2 ,3). Both APIs, factory constructor and function based one, are equally supported. It only depends on your personal taste.

Here is a list of all collection creation APIs.

Kotlin like, function based syntax

  /// List
  // Create immutable lists
  emptyList<int>();
  listOf(1, 2, 3, 4, 5);
  listFrom([1, 2, 3, 4, 5]);
  // Create mutable lists
  mutableListOf(1, 2, 3, 4, 5);
  mutableListFrom([1, 2, 3, 4, 5]);
  
  /// Set
  // Create immutable sets
  emptySet<int>();
  setOf(1, 2, 3, 4, 5);
  setFrom([1, 2, 3, 4, 5]);
  // Create a mutable set which keeps the order of the items
  linkedSetOf(1, 2, 3, 4, 5);
  linkedSetFrom([1, 2, 3, 4, 5]);
  // Create mutable, unordered hash-table based set
  hashSetOf(1, 2, 3, 4, 5);
  hashSetFrom([1, 2, 3, 4, 5]);
  
  /// Map
  // Create immutable maps
  emptyMap<int, String>();
  mapFrom({1: "a", 2: "b"});
  // Create mutable maps
  mutableMapFrom({1: "a", 2: "b"});
  // Create mutable maps without specified order when iterating over items
  hashMapFrom({1: "a", 2: "b"});
  // Create mutable maps which keep the order of the items
  linkedMapFrom({1: "a", 2: "b"});

Dart like, constructor based syntax

  /// List
  // Create immutable lists
  KList<int>.empty();
  KList.of(1, 2, 3, 4, 5);
  KList.from([1, 2, 3, 4, 5]);
  // Create mutable lists
  KMutableList<int>.empty();
  KMutableList.of(1, 2, 3, 4, 5);
  KMutableList.from([1, 2, 3, 4, 5]);
  
  /// Set
  // Create immutable sets
  KSet<int>.empty();
  KSet.of(1, 2, 3, 4, 5);
  KSet.from([1, 2, 3, 4, 5]);
  // Create a mutable set which keeps the order of the items
  KMutableSet<int>.empty();
  KMutableSet.of(1, 2, 3, 4, 5);
  KMutableSet.from([1, 2, 3, 4, 5]);
  // Create mutable, unordered hash-table based set
  KHashSet<int>.empty();
  KHashSet.of(1, 2, 3, 4, 5);
  KHashSet.from([1, 2, 3, 4, 5]);
  // Create a mutable set which keeps the order of the items
  KLinkedSet<int>.empty();
  KLinkedSet.of(1, 2, 3, 4, 5);
  KLinkedSet.from([1, 2, 3, 4, 5]);
  
  /// Map
  // Create mutable maps
  KMutableMap<int, String>.empty();
  KMutableMap.from({1: "a", 2: "b"});
  // Create mutable maps without specified order when iterating over items
  KHashMap<int, String>.empty();
  KHashMap.from({1: "a", 2: "b"});
  // Create mutable maps which keep the order of the items
  KLinkedMap<int, String>.empty();
  KLinkedMap.from({1: "a", 2: "b"});

Summary #

This release of Kollection fully covers the project with unit tests, from 52% to 99% 🎉. By doing that bugs where discovered and fixed.

Because Dart doesn't support non-nullable types yet, this update manually checks all method arguments at runtime. Passing null in any method will throw ArgumentError unless documented otherwise.

Behavior changes #

#36 All method arguments are now validated for nullability. If a argument isn't documented as "nullable" the method will throw ArgumentError (when asserts are enabled)
#51, #46 KIterable<T>.associateWithTo, Kiterable<T>.filterTo, KIterable<T>.filterIndexedTo, KIterable<T>.filterNotTo, KIterable<T>.filterNotNullTo , KIterable<T>.groupByTo ,KMap<T>.mapKeysTo ,KMap<T>.mapValuesTo, KIterable.toCollection did not compile when called directly due to dart-lang/sdk/issues/35518. The type of destination of those methods has been changed to a dynamic type (i.e. KMutableList<T> -> KMutableList<dynamic>). Those methods will now be checked at runtime. This has one advantage: It allows to pass in contravariant types.

final KIterable<int> iterable = listOf([4, 25, -12, 10]);
final result = mutableListOf<num>(); // covariant!
final filtered = iterable.filterIndexedTo(result, (i, it) => it < 10);
expect(identical(result, filtered), isTrue);
expect(result, listOf([4, -12]));

#56 KMutableEntry.setValue now throws UnimplementedError because of bug #55. It anyways never worked.
#58 KSet doesn't allow mutation of its elements with via set getter. It is now really immutable.

API changes #

#38 Breaking: Removed hashMapFrom(KIterable<KPair>) because, unlike Kotlin, it feels unnatural in Dart. Instead use hashMapOf to construct a KMutableMap
#17 Breaking: KMap.associateBy now takes only a single parameter (K Function(T) keySelector). If you used valueTransform use KMap.associateByTransform as replacement
#23 New KMutableList.[]= operator. Example: list[4] = "Hello"
#47 New KMap methods filter, filterTo, filterNot, filterNotTo,
#37 KCollection.random now optionally accepts a Random as argument which can be seeded
#39 KMutableList.removeAt now throws IndexOutOfBoundsException when index exceeds length or is negative
#18 KMutableCollection: addAll, removeAll and retainAll now receive KIterable as parameter, was KCollection

Bug fixes #

#18 Fixed KList.first stackoverflow
#44 Fixed Klist.single stackoverflow
#24 Fixed KList.last which returned first
#20 Fixed KIterable.firstOrNull which threw NoSuchElementException for empty lists, now returns null
#22 Fixed KIterable.mapIndexedTo, KIterable.mapIndexedNotNullTo couldn't be called due to a generic compilation error
#26 Fixed KList.containsAll returned false when all elements ar in list
#28 Fixed KListIterator.nextIndex was off by one, now returns the index of the element which will be returned by next()
#30 Fixed KMutableList.sortBy and sortByDescending not sorting the KMutableList but a copy
#31 Fixed KIterable.none always returned true (Was always working for KCollection)
#51 Fixed KSet.==() returns false for setOf<int>([1, 2, 3]) == setOf<num>([1, 2, 3])

Documentation changes #

#57 Document hashSetOf and linkedSetOf
#19 KIterable.any document return value when called without predicate
#51 Document expected type of now dynamically typed KIterable<T>.associateWithTo, Kiterable<T>.filterTo, KIterable<T>.filterIndexedTo, KIterable<T>.filterNotTo, KIterable<T>.filterNotNullTo , KIterable<T>.groupByTo ,KMap<T>.mapKeysTo ,KMap<T>.mapValuesTo, KIterable.toCollection

Other changes #

Added a lot of tests #19, #27, #32, #33, #34, #35, #39, #40, #41, #42, #43, #45, #53, #54, #58,
#48, #49, #50, #59 Activated many lint checks
#25 tool/run_coverage_locally.sh now installs deps only when not installed and prints resulting HTML report path
