You are always welcome, Jack!

I've actually have discovered this option quite recently myself. RSpec is an endless well of goodness.

Thanks, Phil. That’s exactly what I was looking for. I never knew that additional configuration objects existed!

I think you're looking for this option:

```
RSpec.configure do |config|
config.expect_with :rspec do |expectations|
expectations.max_formatted_output_length = 1000
end
end
```

I am comparing some complex array/hash structures for “eq”, and I would like to display the **entire** object if the comparison fails, without replacing the middle with ellipses to shorten the output. I know some work was done in this area in Issue #2535 in rspec-core, but looking at configuration the only setting I see that looks like it **might** have an effect is #max_displayed_failure_line_count, and setting that to 100 had no effect on the output.

If there is solution within the realm of custom matchers, I could do that since I am using a custom matcher I wrote in order to “customize" the rules of “eq” on these structures.

If the solution is something that must be applied to specific example groups, that would also be more than acceptable.
