Okay, I guessed I missed that when browsing the code. Is mimetype a
property of Document? (I don't have the code in front of me)

Yeah, "smart" indentation is what I was thinking of.

That's one heck of an upstream dependency just to get a text editor :-)

I'd like to have an integrated text editor that will allow for
scripting extensibility in my application (mainly Boo, but ideally
Python or Ruby also). In Windows, I can use the ScintillaNET
(http://www.codeplex.com/ScintillaNET) bindings that give me an easy
to use editor with the following features:
 - syntax highlighting
 - code folding
 - code completion API

I was hoping to be able to use the MD component as it seems (correct
me if I'm wrong) that GtkSourceView lacks the last two. And, as far as
I know, there is no way to use Scintilla with Gtk# without writing my
own bindings.
