LuaCSP

Communicating Sequential Processes in Lua: an extension.

LuaCSP library is a framework that allows you to create pseudo-concurrent programming language embeddable in your application.

Why?

The world is parallel. Typical simulation and robotics projects deal with many entities acting and interacting concurrently.
Event-oriented systems (command+callback, finite state machines - FSMs) can be implemented very efficiently but the resulting model logic is quite fragmented, as the scheduling and the evaluation of conditions are scattered throughout the event routines.
Callbacks and FSMs are way too low-level. FSMs are non-composable.
Asyncronous "push" multi-threaded systems are hard to program and understand. Whould be nice to orchestrate them at a higher level in synchronous way: back to natural control flow - stack and sequence are very powerful abstractions.

We should resolve these complexity and maintainability issues.

How?

We introduce next level you model in: embeddable Lua-based programming language with concurrent control-flow semantics.

So, LuaCSP:

Uses the Occam programming language ideas by Tony Hoare (the author of Quicksort).
Follows the principle of compositionality.
Introduces restrictions and rules, how entities behave and interact.
Extends Lua in standard way, includes it as a subset.
