[ruby-core:122610] [Ruby Feature#21454] "undefined method 'break' for an instance of Binding"

[vo.x (Vit Ondruch) via ruby-core]

Issue #21454 has been reported by vo.x (Vit Ondruch).

----------------------------------------
Feature #21454: "undefined method 'break' for an instance of Binding"
https://bugs.ruby-lang.org/issues/21454

* Author: vo.x (Vit Ondruch)
* Status: Open
----------------------------------------
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.

Issue #21454 has been updated by nobu (Nobuyoshi Nakada).


Use no-dbg.rb with `RUBYOPT=-rno-dbg` when you run without `rdbg`.

```ruby
class Binding
  def break = nil
end
```

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.

Interesting idea. Assuming that I should request this feature in rdbg project.

Sorry, could you please elaborate? Maybe share some example?
