Consistency Script

Consistency script (CS) is a DSL targeting the development of IoT applications. It is as superset of Javascript, containing built-in constructs for data replication and consistency.

A CS application is a collection of services, where a service is a container for distributed data and operations on that data. Programmers are provided with language constructs for various consistency models, including strong consistency and strong eventual consistency (SEC).

Installation

Consistency Script is a Node.js module available through the npm registry. Node.js is required in order to install Consistency Script. Install Consistency Script using the npm install command:

$ npm install cscript

How To Run

Since ConsistencyScript is a DSL built on top of javascript, one first needs to compile his application to javascript before it can be ran. ConsistencyScript files must use the .cs extension and can be compiled using the following command:

# Compile project
$ "$(npm bin)"/csc "$PWD" <main_file> <out_directory>
# e.g : "$(npm bin)"/csc "$PWD" ./Examples/cs/distributedDNS/distributedDNS.cs ./Examples/cs/distributedDNS/compiled

# Run project
node ./compiled/<main_file>

The above csc command compiles the main file as well as all CS files in the same directory and any of its subdirectories. After the compilation we run the project as a regular Node.js project.
