Add some description of updating to the FAQ / Usage

[lucas-clemente]

I just found cask and am curious about your idea of handling app updates. Should I just normally use the app's update feature or wait for a cask update? Does it matter at all? ;)

I think a paragraph describing this should be added to the FAQ or maybe Usage, since I think many users might have that question.

No, it doesn't really matter. Just from the way apps check for updates, it's more likely they’ll warn you before the cask gets updated anyway — I’d guess a lot of contributions come from people who got the app update warning a little before. The syntax is not really definitive yet, and that also causes some issues with upgrading, currently.

As far as I know, you’re the first one to raise that issue (which doesn’t mean, naturally, you’re the only one thinking it), but I don’t really think such a note is necessary. The system is versatile enough that you can do it however you’d like without a problem (except for the aforementioned case, that is being looked into).

I just started using Cask and wondered about this too. Some hint in the README (even just a link to this bug) might be very helpful...

Chiming in here, a note would be helpful to me as well.

Or maybe considering issues with brew cask upgrade (#309), letting the app do it would be best

Here's an awkward case: TextMate 2 currently tells you when the version is old (and won't let you run versions if they're really old), but instructs you to download the latest version from the website. Because it's a "latest" version cask, there's no way to upgrade it with brew-cask. I can't even uninstall/reinstall, because it caches the download.

What's the right way to do this?

[Peeja]

Hmm, I think I misunderstood. TM2 still has Sparkle, but it also has code which makes the app stop launching once it gets too old. That system has a warning when it gets closer to the cut off date, which has started to fire. But Sparkle claims I've got the latest version. I guess I just need to wait for a new version to be released.

Regarding

Because it's a "latest" version cask, there's no way to upgrade it with brew-cask. I can't even uninstall/reinstall, because it caches the download.

Currently the best way to achieve this is to clear homebrew’s cache. brew cleanup --force -s && rm -rf $(brew --cache)' && brew cask uninstall textmate && brew cask install textmate

Our FAQ has several notes about updating. 🙆‍♀️
