Research direction
Start by inspecting the existing STTextView ruler implementation and the CodeEditTextView entry point to understand the current ruler behavior. Encapsulate an NSRulerView subclass in CodeEditTextView and preserve the basic ruler functionality that exists today; the listed preference, line-number, folding, and comparison enhancements are explicitly out of scope.

Description
Description
The vertical ruler (NSRulerView) has a number of requirements that no longer can be efficiently met by STTextView's implementation.
The recommendation is for an NSRulerView subclass to instead be encapsulated within CodeEditTextView, to provide easier workflows for contributors to customize and enhance it. See the bottom of this description for a list of proposed enhancements after this port is complete.
The goal of this enhancement should be to provide basic RulerView functionality aligned with what exists today in the project. It is not to implement the enhancements listed below!
Future enhancements will likely include
- support for the same preferences available in Xcode's preferences:
- toggle line numbers on/off without hiding other RulerView features
- A code folding ribbon
- Code comparison controls
- Dominant language
- Swift
- Stars
- 720
- Forks
- 162
- PR merge metrics
- No merged PRs in 30d
