An abstracted library for interacting with the file system, registry, etc.
We all know the .NET Framework APIs for dealing with the file system are not designed with testability in mind. Also, I wasn't happy with the existing libraries for providing an abstraction for such things. I wanted one that was:
Enumerate*
methods for example.Rothko is this library. It provides abstractions for:
The starting point for Rothko is the OperatingSystemFacade
class. From there
you can get to the other abstractions.
IFileSystem
IEnvironment
IRegistry
The goal is to use this in GitHub for Windows as well as any other applications where testability is important.
A secondary goal is to make it very easy to port code using the core .NET
Framework APIs to port over to Rothko. The interfaces map closely to the
.NET Framework's, except in a few places where I wouldn't be able to live with
myself if I didn't modernize the library. For example, I updated methods
that return arrays to return IEnumerable
(or derived interface) instead.
Once these low level abstractions are implemented, I plan to add a set of Facade classes that provide a more usable API that we all wished had been there all along. These Facade classes will simply delegate to the lower-level abstractions.
