Creating and Using a Local Module with WebIDE

Setting up a project in WebIDE
In the upper right click on the gear icon and then select project.
Click on Select Directory for Sandbox.
I created a directory called EP1.

If you use Windows Explorer to examine the EP1 directory you will find several sub directories created by WebIDE named:
EP1
Projects
Modules
Binary
Firmware
Snippets
Testing
Testinglog
All are empty except for one txt file in snippets.

Copy the attached file testAdd.js into the projects folder.
Copy the attached file Add.js into the modules folder.
Load the file testAdd.js from EP1/Projects into the right side of the WebIDE.
Connect to the Espruino device and the run the program.
The testAdd.js code:

/*Playing with modules

Comments

Example of use of local module in code
*/
var r = new (require("Add"))(1,2);
  console.log(r.read());

The output:

>echo(0);
3
=undefined
> 

The module code in Add.js

/* Copyright (c) 2016 MyName See the file LICENSE for copying permission. */
/*Playing with modules

Comments: Demo of a simple local module.
Dependencies: no other modules are required 
Example of use code
var r = new (require("Add"))(1,2);
  console.log(r.read());
*/
function Add(a,b) {
  this.A=a;
  this.B=b;
}
exports = Add;
/* Returns sum of A and B*/
Add.prototype.read = function() { return this.A+this.B; };

For you to try:
Also attached is an upgraded module timeobj.js and a project file testTimeObj.js.

The output of testTimeObj.js

The code in TestTimeObj.js

//Code to test TimeObj
function Testit(){
//Create an instance of TimeObj from module file
var T= new (require("TimeObj"))();
//Get current time
 T.updateTime();

//Start stopwatch
 T.SWstart();

//Day of week
 console.log(T.getDay());

//Formats for Date
var aa=[['D','/','M','/','Y'],
        ['M','/','D','/','Y'],
        ['Y','/','M','/','D'],
        ['D','/','m','/','Y'],
        ['m','/','D','/','Y'],
        ['Y','/','m','/','D'],
        ['D'],['M'],['m'],['Y'],
        ['D','-','M'],['m',' ','D']
        ];

//Display the different Date formats
  for(var i=0;i in aa;i++)
  console.log(T.getDate(aa[i]));

//Formats for time
var bb=[['H','/','M','/','S'],
        ['H',':','M',':','S'],
        ['M','/','S',':','H'],
        ['M',':','S'],
        ['S']
       ];

//Display the different Time formats
  for(i=0;i in bb;i++)
  console.log(T.getTime(bb[i]));

//Stop and display stopwatch
 console.log(T.SWstop().toFixed(3)," ms");
}//end Testit

Testit();

Great - thanks! It's good to have some nice examples of using local modules...

Is there a simple example of how to make and use snippets when using the webIDE?

Load WebIDE and connect to a board.
Click on the gear icon
Click on projects
Take the snippets tour

Just what I needed. Thank you very much.
