SynapseGrid is an original approach to implement functional reactive programming paradigm in Scala. The library is based on a solid foundation of Petri nets.
A few words about what SynapseGrid is:
- framework for constructing systems that are:
- reactive
- event-driven
- resilent
- it resembles other modern event-driven architectures (ScalaRx, Akka Streams, Spark, etc.).
- SynapseGrid allows function composition of "multifunctions" (functions with a few inputs and outputs). It is more flexible than monads composition of Kleisli Arrows.
- Strictly typed message handling in Akka actors (more natural than in Typed actors or Typed Channels).
- Multi input/multi output functions (multifunctions).
- Systems process portions of information ASAP. The grid can be the base of real time systems.
- It is possible to nest subsystems (like matreshkas) creating modular systems.
- Declarative composition in the form of DataFlow diagram.
- Easy to use DSL:
val a = contact[String]("a")
val b = contact[String]("b")
val c = contact[Char]("c")
a -> b flatMap (_.split("\\s+"))
a -> c flatMap (_.toCharArray)
inputs(a)
outputs(b,c)
- Dependency injection replacement (accompanied with Scala traits).
- DataFlow diagram for a system can be created easily — system.toDot():
