I would like to add some custom rules for use with the Mozilla codebase.
One of the first I have chosen is to deal with is Cu.import:
Cu.import("resource://gre/modules/XPCOMUtils.jsm");; // Should produce a
global XPCOMUtils... the right thing to do in 99% of our cases.
Picking out XPCOMUtils from the code is simple enough but I don't see how
to add XPCOMUtils as a global.
This is what I have so far:
```
module.exports = function(context) {
return {
ExpressionStatement: function(node) {
var source = context.getSource(node);
var matches =
source.match(/^(?:Cu|Components\.utils)\.import\(".*\/(\w+)\.\w+"\);?$/);
if (matches) {
var imported = matches[1];
var scope = context.getScope();
var variables = scope.variables;
variables.push(imported); // Obviously does not work... how
the heck do I add XPCOMUtils as a global?
}
}
};
};
```
