Ever get sick of typing things like $this->load->view or $this->security->sanitize_filename when building your CI sites and apps? Well I've gathered together all the functions from the CodeIgniter User Guide Class Reference so you no longer have to.
I'm guessing you've already got a copy of Sublime Text 2.
Linux
Download the PHP-Codeigniter.sublime_completions file up above, and drop it in your ~/.config/sublime-text-2/Packages/PHP/ folder. Should work immediately.
Windows & Mac
You're going to need to drop it into wherever your Sublime Text Packages/PHP folder is. I haven't used either OS for a couple of months, but seeing as you're clever enough to understand Git and code in PHP, I don't think you'll have too much trouble,
Just start typing and up will pop the CodeIgniter functions in question.
I've included every CodeIgniter function I could find, but if I've missed anything out, I'd appreciate it if you let me know.
