Instead of
myemitter.emit("event", [arg1, arg2, arg3]);
the API is now
myemitter.emit("event", arg1, arg2, arg3);
This change saves the creation of an extra array object for each event.
The implementation is also slightly more simple.
`include` and `require now` call `promise.wait` on their retrieval functions
making them synchronous. Introduce `include_async` and `require_async` to
do asynchronous retrievals.
`include_async` and `require_async` need testing and documentation.
Update documentation for include, require(). I am mostly removing
information about onLoad(). onLoad is to be depreciated.
There are some issues with loading modules from shebang-executed scripts
that will still need to be addressed, but this works for simple single
script situations.
onExit() is similar to the onLoad() callback. onExit() is called on each
module just before the process exits. This can be used to check state in
unit tests, but not to perform I/O. The process will forcibly exit as soon
as all of the onExit callbacks are made.
There is one major API change in the refactor: filename extensions are now
required when requiring or including modules.
Added extra test to test-module-loading.js.
All the c++ code is now reduced to simple wrappers. The node.fs.File object
is defined entirely in javascript now. As is the actionQueue methods.
This makes the boundaries much cleaner. There is still some thought that
needs to go into how exactly the API should behave but this simplification
is a first step.
