All my Casks were removed at TAP_MIGRATION

[rcmdnk]

Recently I upgraded cask and changed to the new repository.
In this time, all my Casks were removed because they were in previous repository location.

Fortunately, I have my Casks in different place, too, and can recover.

But I think it is better to warn it in TAP_MIGRATION.md before brew upgrade brew-cask.

Hi!

We can certainly put more warnings in the doc and/or code more defensively to make the changes easier on the user.

But I don't quite follow what happened in your case. No state about which Casks are installed is stored in the Tap. In fact very little state about which Casks are installed is stored anywhere. The only info we have to track installed Casks is the directory names under /opt/homebrew-cask/Caskroom. That directory didn't change.

Maybe it would help me understand the specifics if you give me an exact command that gives you a surprising response.

Sorry you had trouble with the migration!

Hi,

What I did is creating my Cask with brew cask create simplefloatingclock command.
So, my Cask files were directly in
/usr/local/Library/Taps/phinze/homebrew-cask/Casks/
which was deleted during the migration (it is actually expected behavior, but I could not be careful on it...).

Applications themselves were kept and I could use them w/o any changes.

In this case, cask show like:

$ brew cask list
alfread bettertouchtool ... simplefloatingclock (!) ...

These applications were shown with (!), then I realized that Cask files were not there.

Actually, it was not a big matter for me, but I think it is more safe if there is one comment on it.

Anyway, thank you for such a useful tool, and extensions such create command are also greatly working!
