669486 - Both the Style Inspctor and GCLI use the same template engine, but different copies of it

Status: VERIFIED FIXED

Here's what I think we need to do:
- Tweak it so the implementation is static
  (i.e. a single function or set of functions)
- Move it out into a JSM
- Have the Style Inspector import it
- For GCLI:
  - Tweak dryice to allow several implementation of the same module
  - Create a new templater module that just defers to a JSM
  - Ensure that we can package a built in templater for html
    and the proxied one for firefox
- Ensure the in-tree version is commented to point out the other
  versions of the same code

In my naivety I thought that once the templater was in a JSM both tools could import and use it. I guess the GCLI is a special case :o/

If only we had Harmony modules, this would be easy ....

why can't you use the JSM?

Because gcli is also used in other web apps (such as ace).

Or just have the Firefox dryice build ignore the templater requirement, and have a check in the code like this:

var DomTemplate = require('path/to/dom-template');
if (!DomTemplate) {
  if (typeof Components === 'object'
      && typeof Components.utils === 'object'
      && typeof Components.utils.import === 'funciton') {
    Components.utils.import('resource:///path/to/dom-template');
  } else {
    throw new Error('blah blah blah');
  }
}

Not sure if that is cleaner though...

Or half way:
- Have dryice ignore the templater requirement
- Add to prefix-gcli.jsm:

var x = {};
Components.utils.import('resource:///path/to/dom-template', x);
define('path/to/dom-template', [], function(exports) {
  exports.DomTemplate = x.DomTemplate;
});

That way all the client code can just import and be done.

That seems best to me, for sure.

Joe: I have already moved DOM Templater into a jsm as part of bug 582596. I will submit the new patch in the next couple of days.

Okay ... I will move it to devtools/shared and let you know when Dolske approves the patch.
