vnls-promise v0.0.2

vnls-promise

Cross platform Promise.

Install:

Nodejs:

On node nodejs

npm install vnls
npm install vnls-event
npm install vnls-promise

Then, somewhere at the top of your code

require('vnls');
require('vnls-event');
require('vnls-promise');

There is no need to bind it to a var because var VNLS is made global to the nodejs process so it's behavior is exactly like in a browser environment. All-though this IS a kind of pollution on nodejs.

Browser

In a browser (you may also download the file first):

 <script type="text/javascript" src="https://raw.githubusercontent.com/jorritd/vnls/master/lib/vnls.min.js"></script>
 <script type="text/javascript" src="https://raw.githubusercontent.com/jorritd/vnls-event/master/lib/vnls-event.min.js"></script>
 <script type="text/javascript" src="https://raw.githubusercontent.com/jorritd/vnls-promise/master/lib/vnls-promise.min.js"></script>

Usage:

var promise = VNLS.getObject('event',"Promise");
promise.Do('set a timeOut and 2 increments',
  // Can we pass something
  // extra to 'this' promise
  function(promise){
    callback_counter ++;
    
    setTimeout(function(){
      // promise.done();
      setTimeout(function(){
        
        promise.done();
        
      },100);
    },100);
    
  },
  
  function(promise){
    callback_counter ++;
    promise.done();
  },
  
  function(promise){
    callback_counter ++;
    promise.done();
  }

).whenDone( function(){
  success_called = true;
}).whenFail( function(){
  error_called = true;
});

or:

promise.Do(
  function(promise){
    callback_counter ++;
    promise.done();
  },
  function(promise){
    callback_counter ++;
    // This block is causing an error
    // So the next block will be valid
    promise.fail();
  },
  function(promise){
    callback_counter ++;
    promise.done();
  } 
).orDo(
  function(promise){
    callback_counter ++;
    promise.done();
  },
  function(promise){
    callback_counter ++;
    promise.done();
  },
  function(promise){
    callback_counter ++;
    promise.done();
  } 
).whenDone( function(){
  success_called = true;
}).whenFail( function(){
  error_called = true;
});

or:

promise.Do(

  function(promise){
    promise.done();
  }
    
).thenDo(
    
  function(promise){
    // console.log('Then called');
    setTimeout(function(){
        // console.log('READY');
        // self.pOptions.current_level == 2 at this position
        // console.log(u.inspect(promise),true);
      promise.done();
    },100);
  }

).orDo(

  function(promise){
    // console.log('Or called');
     // console.log('ERROR');
     // console.log(u.inspect(promise),true);
    promise.fail();
  }
  
).whenDone( function(){
  success_called = true;
}).whenFail( function(){
  error_called = true;
});

Dependencies:

vnls vnls-event

Development:

• jasmine-node Testing npm install jasmine-node
• nodewatch Autotesting TDD npm install nodewatch
• uglify-js Building npm install uglify-js
• jake rake, make, ant substitute (Java-script all the way) npm install -g jake

For jake these are the commands:

• jake compress : build minified version in './lib/*'
• jake test : run the specs
• jake autotest : run the specs on a filechange for TDD

For testing in a browser environment just point your browser to 'specs/index.html'. It should run the same specs as jake test does. (The tests cover both browser and server)
