Research direction

Reproduce the issue by entering binding.break, then running list and list - in both the default debugger console and IRB. Compare how the command is parsed; done means predecessor-line listing works in IRB, either with list - or a documented alias.

Written by the indexing model from the issue text.

Description

Your environment

  • ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux]
  • rdbg -v:rdbg 1.9.2

Describe the bug

Here is the list - command to see predecessor lines (useful after regular list usage).

It works in a default console, but not in IRB: it considers - as an operator, I suppose.

To Reproduce

  1. binding.break in a code.
  2. list in IRB console.
  3. list - in IRB console.

Expected behavior

Working list - command (or an alias).
