This is a subset of the Buttercoin.com codebase for performing order matching, reporting market status, and generating notification resulting from trade execution. The project uses SBT and is composed of several sub-projects:

• common contains code that is or likely will be shared by other systems.
• core provides most of the engine functionality.
• models provides some data models and the notion of an engine snapshot. Parts of core should probably be moved here.
• perf-testing has a set of ScalaMeter micro-benchmarks.

This repo doesn't yet include mechanisims for handling user accounts, processing external transactions, connecting over HTTP, or many other things, since those are largely separable concerns.

• A demo container application that starts up the engine and accepts external connections
• akka-persistence support for write-ahead journaling
• Performance tuning

To run all unit tests (but not performance tests), simply run sbt test.

To run performance tests without the "GC detected." spew use:

sbt "project perf-testing" "test-only -- -silent" | grep -v "GC detected."

There are a couple of Typesafe Config files under resources which control currencies available in a locale and fee structure.

This project will be maintained under the Semantic Versioning guidelines as much as possible.

Releases will be numbered with the follow format:

<major>.<minor>.<patch>

And constructed with the following guidelines:

• Breaking backward compatibility bumps the major (and resets the minor and patch)
• New additions without breaking backward compatibility bumps the minor (and resets the patch)
• Bug fixes and misc changes bumps the patch
