Thanks for the thoughtful response. My question was a bit "tongue in
cheek." I'm an experienced programmer and
I've worked with a lot of languages and environments for over 25 years. I
started out my post saying that I was working
on a program that is fairly unusual because the system I'm building is
creating objects with code that gets executed
and the loading and unloading of the modules is managed by the master
program.
I ran across "bind" and thought it might be a solution, but I hadn't
experimented with it yet.
In more detail, my scenario is this:
Master program:
Reads a directory containing JavaScript looping through each one and doing
this:
var myobj = require( the-file );
eval( 'myobjs.' + file-name = myobj;');
So, now I have an object 'myobjs' that has a reference to each object I've
loaded.
each file I'm loading looks something like this:
module.exports = {
data1: "blah",
data2: "blah",
initialize: function(ctx, self) {
//your code here that can't access data1 or
data2 without self :-)
}
};
When I want to run one of the myobj.initialize functions, I'm currently
doing this:
var self = eval(myobjs.filename);
eval(myobjs.filename.initialize)(myctx, self);
This solution appears to work.
