Custom Indentation, ICSharpCode.TextEditor?

[Easelm]

I'm creating a Lua program using ICSharpCode. Now, what I'm asking is how would I code the Indentation? My friends and the community I'm in were asking if I could add this for them, but I wouldn't know where to start.

Only things I have seen is people using 'Trim', etc. So, if anyone could post an example, that would be nice.

Example of what I'm talking about:

Incorrect:

function Action(Event)
end

Correct:

function Action(Event)
end

Or with multiple statements:

function Action(Event)
  if(a < b)
  end
end

Basically, I want it to make the 'end' join with 'function', 'if', etc; when they aren't in the correct position.
