What is this dashed line called that aligns function blocks in my IDE?

Question

The SPE IDE that I use for my Python code uses this "visual cue" that looks like a vertical dashed line for alignment of (what I would call) function blocks. How can I get this option in Visual Studio 2008?

Here is what it looks like:

Answer 1

I've seen it called structural highlighting or code outlining.

There's a Visual Studio plug-in called CodeRush from Developer Express that supports this (bottom of the page) and a lot more.

update:

As divo mentioned, there is a free lite version of CodeRush. I confirmed that it includes structural highlighting.

Answer 2

Unfortunately, Visual Studio does not support indentation lines out of the box.

Answer 3

These lines are arguably more useful in Python where indentation denotes nesting. In C#, nesting is explicitly marked by curly braces. I feel as though curly braces provide the visual cues I need to see this kind of thing, so you might just try to persevere -- in time the cognitive load associated with glimpses of C# versus glimpses of Python will reach equilibrium.

VS2010 implements the text editor in WPF and there are some examples online of creating plug-ins that augment the text editor area. This could be a fun project without being too difficult.

I am envious of Python's indentation-centric nesting. I wish that the C# compiler supported something like that. I wish that white space was part of the language. It would make tooling support for the language better as well.
