Hi, this is Robin again, and we'll be going over Code Assist profiles in this presentation.

First of all, what is Code Assist exactly? Well, much like it sounds, it's the ability to get insight onto your code as you're typing. For example, here we have a function declared and if we invoke it here or later in the program, you can see, first of all, we have a proposal window here that tells us all the properties or functions that are available. Then, if we open the paren, it'll tell us what Args we need to us and what type they are. So, for example, here we can say that's a string, we know it, and now we're on the second paren, we can see it, it's highlighted in bold and that's a number. Alright. So that's was Arg Assist is.

But very quickly you may find that in JavaScript and HTML especially, you'll be working with multiple files at once. So what we need is a way of grouping these files together, so it's not all the JavaScript files in our entire hard drive, but a subset of those.

The first thing we have here is what's called the Code Assist profiles window. As you can see from the text in there, you can drag any HTML or JavaScript file into the window, and it will become part of a profile. We call this the default profile. Just like before, we can open it up and get Code Assist against it. You can see here, this comes from file1.js and it's myFunction, just like before.

Well, the second thing we can do is drag a second file into that profile. Now if we open it, we can see that this second file also has insight into the first file. If we spell that correctly, we can see we have myFunction from file1 and the currently declared myFunction2 from file2. If we chose myFunction1 just like before, we get Argument Assist. We know this is supposed to be a string and this is supposed to be a number. We can go to the other file.

One of the things we can do now, we can hover over myFunction. We can tell where that's coming from and we can also navigate or press the F3 key and go right to that declaration. Now we're back in file1. From file1, because these are both in the same profile, of course, we can see myFunction2 from file2. So these now become a set. Of course, we get Arg Assist on this as well, if we like. We can close this profile out now and close these files. We won't save them.

Next, we can look at HTML Code Assist. Here we have an HTML file. You notice automatically there was a Code Assist profile created. It added file1.js and file2.js automatically. If you look at the script tags in the demo.html, you can see there's file1 and file2. As we add and remove script tags here, you can see that they're added and removed from the profile. We can also reorder these and they'll be reordered in the profile. Of course, now that we have Code Assist on these two files, if we type myFunction here, we get file1.js and, just like before, we can add a string parameter and we can add a number parameter.

The last thing you might want to do is if you right click, you can make this profile permanent. That means the next time you start up the editor, it will automatically open demo.html profile and that will include these files. Thank you. That concludes this presentation and I hope you enjoy the new Aptana IDE.
