I've managed to enable jQuery support using this tutorial How to enable jQuery support in Aptana Studio 3 and using code completion with:
$. or $("p").add( ...
works. But in my projects I need to use the nonconflict Version. So I added this:
<aliases>
<alias name="$" type="jQuery"/>
<alias name="jQuery" type="jQuery"/>
</aliases>
but this doesn't seem to work.
This tutorial http://wiki.appcelerator.org/display/tis/Using+JavaScript+Libraries says
Save it to your disk, and then drag it into your project. It does not matter where in the project it sits, so you can create a new folder for files like this if you like.
so I added a folder /source/support to fit my structure and add .sdocml files there.... but nothing seems to happen. So I'm not really sure if adding the file actually does something. Tried adding it a couple of times, but this doesn't seem to trigger anything.
Any clues?
