There is a minor change to how backtraces are formatted. It’s now the same as what rspec shows when ran from directly:

I am waiting for review and merge from owner

Sorry that this hasn't had attention in a while, @jasoncodes.

I really like this idea, but I'm very concerned that the parsing code seems to be a bit brittle and may break if future rspecs change output formats slightly. I'm not sure what the best answer here, which is why I haven't really jumped into it. 🤔

[jasoncodes]

What if I made the guards less strict so instead of raising on an unexpected format, they instead silently continue? This should at worst output a bit of duplication instead of erroring.

I’m not sure how to best add coverage for that though. Conditionally stub out fully_formatted_lines so it does something different than expected? Not sure if it’d be worth the effort.

@sj26 Sorry to bother, but do you have any further opinion on this?

[taylorthurlow]

@sj26 Any chance of an update?

[dschweisguth]

Right now we're running on a fork based on this PR. I too would appreciate any opinions on a way forward. Thanks!

[dimitarizpitaime]

Any updates on this guys, would really love to see it going in ?

[krasnoukhov]

This would be a great addition to merge and then cut a release...

[Drowze]

@sj26 any chance we can get this one on a new release? :)
