I realize that if objects is empty…
i.e. nothing is return from $(selector) when you do a $(selector).myplugin();

result = result[0]; // result[0] is undefined here. which means result.$ = objects; will throw an error..

so i added a check right in the beginning to return nothing…

(function ($) {
    $.fn.encapsulatedPlugin = function (plugin, Definition, objects, options) {
       
        // steal this from Jörn Zaefferer’s Validation plugin http://bassistance.de/jquery-plugins/jquery-plugin-validation/

        if (!objects.length) {
            options && options.debug && window.console && console.warn(“nothing selected, can’t create, returning nothing”);
            return;
        }

Let me know your thoughts/opinions… =D

That’s good to know, thanks!

I had 10 GB (!) in the ~/Library/Mail/V2/IMAP-[accountname]@gmail.com@imap
.gmail.com/[Gmail].mbox/All Mail.mbox folder. (Where [accountname], obviously, is replaced by my Gmail account name.)

(Note: Starting with Lion, the ~/Library folder is hidden by default in Finder. In order to make it visible, you have to enter the appropriate incantation at the command line. Instructions here: http://lifehacker.com/188892/show-hidden-files-in-finder)

I followed the Mail configuration instructions posted here, so the “All Mail” folder no longer appeared in Mail. However, the All Mail.mbox folder whose path is given above remained on my hard drive, still taking up 10 GB.

Since I had a current backup, I decided to take the plunge and delete that All Mail.mbox folder. Once it was gone, I opened Mail again. All my messages was still where they had been before.

I also signed into Gmail’s web interface just to make sure, and everything was still where it had been there, too.

So it looks like Mail doesn’t automatically remove the .mbox folder for a Gmail label when you stop showing it in IMAP, but it also looks like you can remove it manually if you want to, and free up the hard drive space.

I was declaring my plugin definition like this:
MyPluginDefinition = function() {
   /* stuff goes here */
}

So I was ignoring the “element” and “option” variables that you pass in.

But if I modify it to actually use what you pass in, then I can pick up the element and use it with the normal jQuery calling convention. For example…

MyPluginDefinition = function(element, options) {
    function _storeWidth() { var width = $(element).width(); }
}

In other words, if I call $(#foo).myplugin().publicMethod() and inside of public method I want to do something to the jQuery object selected by $(#foo), how would I do that?

I was thinking it would be, e.g., this.$.width(). However, that doesn’t work…
