CommandEvents

JS file to allow cross extension function calls

This script allows you to send commands to other extensions also using it. Access to functions is granted based on a whitelist. You can whitelist a function by adding its path to eventCmd.whitelist. For example, lets say you have a function Model.getContacts();, to expose this function you would add 'Model.getContacts' to eventCmd.whitelist.

Lets say that an extension called UserTagger has a function like: Model.getUsertag('Username');. If they have added this function to their whitelist, you can call the function as follows:

eventCmd.send('UserTagger', ['Model', 'getUsertag'], ['Username'], function(usertag){
    console.log("Received usertag:" usertag);
});

The arguments for eventCmd.send() are as follows:
TargetExtension, Path(Array), Arguments(Array), Success(Callback), Error(Callback).

Functions that are called can either return their value immediately or return a Promise object.

If your function is passed a callback as an argument, you can call this function as follows:

var successCallback = function(){
    // Successful!
    console.log(arguments);
}
var errorCallback = function(){
    // Something went wrong!
    console.error(arguments);
}

eventCmd.send('ExtName', ['Async', 'get'], [eventCmd.eventCmd.successCallback, eventCmd.errorCallback], successCallback, errorCallback);
