interlook-commons

Another library of daily basis tools, one could wish to be included in .NET

Supporting .Net Core 2.2, .NET 4.5.1 and .NET 4.7.2

Description

This package provides several helper classes and extension methods, which try to support general to specific tasks.

It contains:

• Collections
  • CompositeObservableEnumerable - an observable sequence, that automatically merges several observable sequences
  • ObservableDictionary - an observable generic dictionary
  • NullEntryDictionary - a generic dictionary with an optional default value, whose key is null
  • NullEntryObservableDictionary - a combination of the two above
• versatile components
  • ChainOfResponsibility<> and AsyncChainOfResponsibility<> - dispatching objects for items, to be processed by different handlers, depending on their status
  • DelegateComparer - an implementation for IEqualityComparer<T> using delegates
  • DisposableToken - base class for objects implementing IDisposable to easily perform actions when disposing
  • DelegateDisposableToken - helper object for actions to execute when leaving an using block
  • MethodResult and MethodResult<T> - classes for return values of methods supporting status
• Eventing
  • EventBus - implements right this, an event bus, offering methods for subcribing and publishing events, supporting filtering, subscription tokens and UI context
  • interfaces and classes to customize/extend EventBus
• LINQ and Functional Programming
  • FunctionalExtensions - extension methods for currying and partial applying functions/actions
  • DictionaryExtensions - helper methods for generic dictionaries (e.g. getting values safely)
  • EnumerationExtensions - helper methods for enumerators and Linq2Objects
  • Classical monads from FP, namely Maybe,Either,Try as well as their lazy versions MaybeLazy,EitherLazy and TryLazy. Notice, that the lazy types are often the counterparts of the native pendants in functional languages (Haskell, F# etc.).
  • Additionally: Reader, Writer and State, which are lazy by default.
• String and text handling
  • checking and comparing string
  • constraining strings
  • encrypt/decrypt text
  • applying (crypto-)hash functions to text
  • multi-strings (indexed alternate contents)
  • parsing strings
  • secure string equality check mitigating timing-attacks
