That looks like a good way of doing things if I were using a heavier IDE, but Sublime Text 2 is a text editor so it doesn't scan your projects in that way (or if it does, I've missed something big style). There are plug-ins which can do that, but I've found they don't work properly, and I use Sublime Text because it is lightweight and I don't need that extra functionality - I first and foremost need speed.
So for me it was easier to write a script to scrape the CI User guide and then pile the functions into a single file and slot it into the PHP folder.
