Defined in:
lib/pwn/plugins/repl.rb

Overview

Custom input handler for pwn-ai to support multi-line submissions:

  • SHIFT+ENTER (common terminal sequences) or Ctrl+J / Alt+Enter inserts a newline (continue editing)

  • plain ENTER submits the full prompt (possibly multi-line) to the AI

  • Multi-line pastes are supported (Reline handles n in buffer; submit with ENTER)
