I'm looking for a way in vim to easily visualize the various indent levels of python code. It would help if there was always a vertical rule at the beginning of the current line. That way I can scan down the code to see where the current block ends. Are there any plugins out there that do this?
You could simply emulate indentation guides. It's simpler and more effective, in my opinion. Please, take a look at my answer to the question about indentation guides.
