This is actually not doing what you think it does.

criteria.file.include? 'compressed-encoding=application/zip;' or 'application/zip; charset=binary'

is effectively this:

criteria.file.include?('compressed-encoding=application/zip;') or 'application/zip; charset=binary'

So, if criteria.file.include?('compressed-encoding=application/zip;') evaluates to false, the return value will be the string 'application/zip; charset=binary'. This leads to a non-nil return value no matter what.

@zachwalton, how do you apply this fix on a running homebrew ?

@salimane You need to apply the changes to /usr/local/Library/Taps/caskroom/homebrew-cask/lib/hbc/container/zip.rb
