Support ~ path syntax in require

[slavchev]

Support ~ path syntax in require. For example

var mymodule = require('~/path1/path2/mymodule');

See:

• Support ~ path syntax in require android#177
• Require with tilde (~) should resolve to the app folder ios-jsc#254

What do you think of:

var mymodule = global.require('./path1/path2/mymodule');

as an alternative? This is already implemented in the master branch of NativeScript for iOS.

Or there's always require.main.require('./my-top-level-module') which I think is the node.js way to do it. It isn't implemented either but seems more logical to me than some string convention.

The string convention seems easier to use to me and is tied with less implicit logic underneath. Additionally, we may provide a property at the file-system module that returns the app root. This will enable a more verbose way to do something like:

var fs = require("file-system");
var appRoot = fs.path.appRoot;
var myModulePath = fs.path.join(appRoot, "my-module");
var myModule = require(myModulePath);

Tilde (require('/path1/path2/mymodule')) is more logical and clean approach to my taste.
It is also consistent with xml layout, e.g.:
<Image src="/res/ctlArrangements1.png"/>

@atanasovg: I would advise against tightly coupling the application assets, including any JavaScript files, to a filesystem idiom. Whether we load assets from a filesystem or something like android.res.AssetManager or NSAssetData is an implementation detail, and as we transition towards ES6 modules this rule should hold even more so.

In general I am against this change. I would much rather we reverted to simpler times when absolute paths passed to require resolved to the app folder in the application package, which would in turn obviate the need for the tilde character entirely.

I tend to agree agree with fealeaenpae.

If the concept of a "root" path is in the system then you should be able to use '/' as the first character to resolve to root.

var mymodule = require('/path1/path2/mymodule');

This is consistent with both the web definition of the "root"

and linux/unix
