cask lost track of some installed casks

$ brew cask info eclipse-ide
eclipse-ide: 4.3
http://eclipse.org
Not installed
https://github.com/phinze/homebrew-cask/commits/master/Casks/eclipse-ide.rb

$ ls -d /opt/homebrew-cask/Caskroom/eclipse/4.3/eclipse/Eclipse.app
/opt/homebrew-cask/Caskroom/eclipse/4.3/eclipse/Eclipse.app

$ brew cask info vlc
vlc: 2.0.8
http://www.videolan.org/vlc/
Not installed
https://github.com/phinze/homebrew-cask/commits/master/Casks/vlc.rb

$ ls -d /opt/homebrew-cask/Caskroom/vlc/2.0.7/VLC.app
/opt/homebrew-cask/Caskroom/vlc/2.0.7/VLC.app

How can I get cask to remember it really did install these casks?

Thanks for the great work on brew cask, it's awesome.

There's two different things here:

$ brew cask info eclipse-ide
eclipse-ide: 4.3
http://eclipse.org
Not installed
https://github.com/phinze/homebrew-cask/commits/master/Casks/eclipse-ide.rb

$ ls -d /opt/homebrew-cask/Caskroom/eclipse/4.3/eclipse/Eclipse.app
/opt/homebrew-cask/Caskroom/eclipse/4.3/eclipse/Eclipse.app

This is the cask eclipse that changed name into eclipse-ide, therefore it didn't forget eclipse is there, it's really reporting (correctly!) that eclipse-ide isn't. You can "fix" it by moving /opt/homebrew-cask/Caskroom/eclipse to /opt/homebrew-cask/Caskroom/eclipse-ide.

$ brew cask info vlc
vlc: 2.0.8
http://www.videolan.org/vlc/
Not installed
https://github.com/phinze/homebrew-cask/commits/master/Casks/vlc.rb

$ ls -d /opt/homebrew-cask/Caskroom/vlc/2.0.7/VLC.app
/opt/homebrew-cask/Caskroom/vlc/2.0.7/VLC.app

This is correct behaviour (although it could be improved): vlc 2.0.8 isn't installed, vlc 2.0.7 is. You should update vlc.

Closing, discussion on behaviour in these situations can be done on #316.

Thanks for the help, @passcod. As for eclipse, I renamed /opt/homebrew-cask/Caskroom/eclipse to /opt/homebrew-cask/Caskroom/eclipse-ide and that problem is fixed. I wonder if there's a way we could handle casks whose names have changed better for users.

As for vlc, I ran brew cask install vlc and now have the latest. Looking in /opt/homebrew-cask/Caskroom/vlc/ I see it's sitting alongside the outdated version. I see there is no e.g. brew cask cleanup command to automatically remove old versions of installed casks. Is that (along with brew cask outdated and brew cask upgrade) planned for a future version? In the meantime, are users meant to remove old versions with something like rm -rf /opt/homebrew-cask/Caskroom/vlc/2.0.7? I'll watch #316 for progress. Thanks again.
