Bug #18389
closed`binding.irb` can fail in some classes that implement `context` and `print` methods.
Description
class Foo
def boop
binding.irb
end
def context
end
def print
end
end
Foo.new.boop
It fails with:
> ruby ./test.rb
From: ./test.rb @ line 3 :
1: class Foo
2: def boop
=> 3: binding.irb
4: end
5:
6: def context
7: end
8:
./test.rb:9:in `print': wrong number of arguments (given 1, expected 0) (ArgumentError)

I suggest that binding.irb
should be a little bit less invasive to avoid these kinds of issues.

[ruby/irb] Changed to call Kernel.print
If you call binding.irb
on a class defined #print
, it will crash, so call Kernel.print
.
Fix [Bug #18389] binding.irb
can fail in some classes that implement context
and print
methods.
