Feature request: --verbose flag

[diamond-lizard]

It would be great if the buttercup executable had a --verbose flag (ideally with selectable levels of verbosity) that would report in detail what buttercup was doing.

This would be very helpful in troubleshooting.

What would you like to know?
Could you give some examples of what problems you had and how a verbose flag would have helped you?

From memory, it was things like exactly what files buttercup was loading, in what order, whether it encountered any errors in them and what those errors were.

I don't remember exactly what the issue was, but I spent hours troubleshooting it only to finally realize that buttercup wasn't showing errors in some of the files it was loading. If it had just shown me what it was doing and what it was finding, it could have saved a lot of time.

But, in general (as this is not limited to the particular issue I was having at the time), I think it would be useful to know exactly what buttercup is up to when doing troubleshooting. Ideally, how much of this information is reported would vary depending on verbosity settings.

@diamond-lizard Maybe verbose/trace mode in Eldev could be useful? E.g. it prints names of test files as it loads them.

It is a build tool that supports Buttercup among other stuff.
