A small framework for managing settings.

• XmlRepository is a baseclass for managing xml files.
• BinaryRepository is a baseclass for managing binary files.
• JsonRepository is a baseclass for managing json files.
• AutoSaver is a baseclass for saving files on changes.

Features:

• T Clone(T item); deep clone by serializing and then deserializing an instance.
• bool IsDirty(T item, IEqualityComparer comparer); check if an instance is dirty after last save.
• Repository manages a singleton reference for each file.
• EqualityComparers that checks structural equality by serializing and comparing bytes. If performance is an issue overloads with IEqualityComparer are exposed.
• Saves to .tmp file, on success it is renamed to .cfg extensions are configurable via settings.
• Creates backups on save. Backurules configurable via setting.
  • Extension
  • Directory
  • Number of backups
  • Max age backups.

Sample:

[Test]
public void XmlSample()
{
    var repository = new XmlRepository(); // Uses %AppData%/Settings. 
    var setting = repository.ReadOrCreate(() => new DummySerializable()); // Uses typeof(T).Name as filename
    setting.Value ++;
    Assert.IsTrue(repository.IsDirty(setting));
    repository.Save(setting);
    Assert.IsFalse(repository.IsDirty(setting));
