How to display source code in a Cocoa app

Question

I like the way Kaleidescope does it in its "Text Scope". Anyone know how they did it or what they used? NSTableView, NSTextView?

Answer 1

The Blame view in Versions (also made by Sofa) uses an NSTableView. I'd guess that they're doing the same thing here. Create an NSTableView with a column for the line numbers, a column for the code, use a monospaced font and tweak the formatting. That will get you pretty close to what they're doing there.
