Nile is a complete reimplementation of the squeak stream hierarchy.
It's based on traits.
You can find it on Universe, SqueakMap, and SqueakSource
A new class diagram is available at:
* Only one class for collection-based streams (0 trait)
* Only one class for file-based streams (0 trait)
* Three new traits to put common behavior (6 traits in the core now)
We did these simplifications following Andreas Raab suggestions. It
proved to be a very good idea as a lot of entities (either class or
trait) has been removed. We are not ANSI compatible anymore but we
don't think it's a real problem in our case.
There is also a backward compatibility package (not loaded by default)
which contains collection-based stream classes to mimic ANSI
behavior: NSReadableCollectionStream, NSWriteableCollectionStream and
NSReadWriteableCollectionStream. They are using the new core. Please
see package NileBackwardCompatibility on SqueakSource.
If you want to experiment ideas with Streams, you can do that on Nile
(for example, using a StreamAtEnd exception to avoid testing for
