Issue #21454 has been updated by ko1 (Koichi Sasada). Status changed from Open to Feedback In today's dev meeting, we emphasized that it's important to ensure `binding.break` (or `debugger`) is removed before release, so having it as a no-op is a bad idea. ---- BTW debug.gem supports specifying breakpoints by adding environment variables for example, and you can ignore them without `rdbg`. However, specifying file and line number is tough, so I think good editor supports makes it better. ---------------------------------------- Feature #21454: "undefined method 'break' for an instance of Binding" https://bugs.ruby-lang.org/issues/21454#change-113993 * Author: vo.x (Vit Ondruch) * Status: Feedback ---------------------------------------- Running my code with `rdbg` and using `binding.break`, it is a bit unfortunate that subsequently running the code without `rdbg`, it fails with error such as: ~~~ NoMethodError: undefined method 'break' for an instance of Binding ~~~ Could this method become no-op if the `rdbg` is not loaded? If there was some concern about this, then it could print some helpful warning or what not. -- https://bugs.ruby-lang.org/
