Error message, hide class name

[Trans]

irb(main):005:0> class X
irb(main):006:1> def inspect
irb(main):007:2> "hey"
irb(main):008:2> end
irb(main):009:1> end
=> nil
irb(main):010:0> x = X.new.nomethod
NoMethodError: undefined method `nomethod' for hey:X
from (irb):10

Anyone know how I can get rid of the ':X' after 'hey'? I've tried:

class X
def self.name; ''; end
def self.to_s; ''; end
def class; ''; end
end

Where is it getting the class name?

Thanks,
T.

FYI, I decided to just chomp off everything after the 'for', so no big
deal. But I still don't understand where the error message was getting
the class name.

But I still don't understand where the error message was getting
the class name.

Tom, the so-called class path seems to be buried deep inside
unaccessible instance variables of the class. For a workaround use a
"#" as the first character of the inspect result:

class X
def inspect
"#hey"
end
end

X.new.x # => undefined method `x' for #hey (NoMethodError)

Anyone know how I can get rid of the ':X' after 'hey'? I've tried:

the problem isn't inspect or anything else to do with X, it is
method_missing. the default method_missing is raising with a message
like:

"undefined method `#{msg}' for #{self.inspect}:#{self.class}"

So you can attack the 'problem' at the source:

method_missing. the default method_missing is raising with a message =A0
like:

"undefined method `#{msg}' for #{self.inspect}:#{self.class}"

^^^^^^^^^^
Which is why I thought I should be able to override #class. And was
surprised that it did not work. Nevertheless...

So you can attack the 'problem' at the source:

That's a better approach --at least in the case of NoMethodError.

Thanks, Ryan.

That's interesting!

Thanks Pit. I think I can use that.
