Dwoo is a simple templating engine similar to Smarty but written entirky in PHP 5 OOP, making it much quicker and lighter.
There is already a implementation for CodeIgniter packaged with the Dwoo download which is pretty sweet, but I am very against the way in which it was done. I don't want to write $this->dwootemplate->load() or anything similar, as if I change parsers (which I have done once or twice) then ALL of my controllers need to change and that's no fun at all.
Instead I decided that extending and replacing the Parser library logic was a better idea, so here is the code to get Dwoo working for you. You of course need to download and install Dwoo, this is just the wrapper library.
It all works EXACTLY the same way as views/parser does in core CodeIgniter, with the addition of adding string_parse() which accepts a HTML string instead of the "view" name.
Code:
