First of all, I would like to extend a special thank-you to the team at FastSpot for keeping BigTree an open-source project. I was in love as soon as I downloaded my first copy and am currently using it for a client project. So thank you for taking the extra time it takes to develop for the open-source community. You're awesome.

If it wasn't clear, this is my first post, so bear with me.

My question is as the title says: has anyone had a need to implement a WordPress-like shortcode parser for the content pieces of their site? I don't exactly feel like writing my own library for a few shortcodes just for buttons and some special image styles. I'm sure someone has found a solution to this problem before.

Has anyone used a PHP library for this in the past that they would recommend? Would it be easier accomplished by modifying the TinyMCE editor?

What I have in mind is just something basic like:
[button url="http://google.com" color="red"]Click Me![/button] would transform into <a href="http://google.com" class="btn btn--red">Click Me!</a>

Thanks guys!
