Maya Flow-Based Toy Robot Engine

This language engine has been adapted from the language-agnostic flow-based language Cascades in order to create a toy sandbox to experiment with dynamic generation of DAGs (Directed Acyclic Graphs). It has a limited dictionary of components that can be wired together to do various complicated tasks.

Cascades - Language-Agnostic Programming Framework for Data-Driven Applications

Cascades is language-agnostic dataflow programming framework that implements a number of the Flow-Based Programming (FBP) concepts. Although we consider Cascades to be a general-purpose programming framework we have created it having a, as J. P. Morrison described: a data factory mental image in mind, where the application is expressed as a series of transforms on data streams - which requires fundamental changes from the old von Neumann thinking in the way programmers build applications.

Features of Cascades

• Cascades is cross-platform (can be used on OSX/Linux/Windows, tested also on Raspberry PI and Beagleboard Black) and completely written in Go programming language.
• Uses ZeroMQ for connections between the components.
• The core components are also written in Go, but you are free to choose any programming language of your choice as long as there are bindings for it (currently it supports: C, C++, C#, CL, Delphi, Erlang, F#, Felix, Haskell, Java, Objective-C, PHP, Python, Lua, Ruby, Ada, Basic, Clojure, Go, Haxe, Node.js, ooc, Perl, and Scala)
• Supports flows defined using NoFlo's JSON format or FBP DSL language.

Usage

General usage is described below:

NAME:
   cascades - A Cascades FBP runtime/scheduler for the FBP applications.

USAGE:
   cascades [global options] command [command options] [arguments...]

VERSION:
   0.1.0

COMMANDS:
   run      Runs a given graph defined in the .fbp or .json formats
   library  Manages a library of components
   help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --file, -f 'library.json'  components library file
   --debug, -d       enable extra output for debug purposes
   --help, -h        show help
   --version, -v     print the version

Get Dependencies

go get github.com/mayahq/maya-toy-engine/cmd/cascades

Building Binary

Building the binary:

go build ./cmd/cascades

Adding new components

Building new components

go build -o components_built/maya/click ./components/maya/click
./cascades library add ./components_built/

Build in bulk :

./build.sh

Add components to library, will be added to library.json :

./cascades library add ./components_built/
OR 
./addToLibrary.sh

Run FBP file

To test that everything is working as expected, run this test.

./cascades --debug run ./examples/maya_test.fbp
