Vim Kill Ring and Yank Support

What

Full vim-style kill ring (yank ring) implementation for the terminal text editor, supporting kill accumulation, yank, and yank-pop cycling.

Details
  • New killRing data structure with push(), getLastKill(), yankPop(), recordYank(), and canYankPop() operations
  • Kill accumulation: consecutive kills are merged into a single ring entry
  • Yank-pop (Ctrl+Y then Alt+Y in emacs-style) cycles through the kill ring history
  • Ring size is bounded to prevent unbounded memory growth
Evidence

Kill ring implementation (search for "getLastKill" and "yankPop")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
