Add versioning to ZeroNet ('0.5.7') current

[BenjaminHCCarr]

The sha256 and version will change but the URL currently won't.

Unfortunately, I don't see a way to automate versioning as their own versioning is out of date: https://github.com/HelloZeroNet/ZeroNet/tags versus the target URLs on https://zeronet.io/

Though this slightly increases maintainer overhead considering it is a security/privacy app, I think a functioning sha is good.

After making all changes to the cask:

• brew cask audit --download {{cask_file}} is error-free.
• brew cask style --fix {{cask_file}} reports no offenses.
• The commit message includes the cask’s name and version.

Additionally, if updating a cask:

Without an appcast that matches the current release this cannot be versioned.

If you still want this to be versioned you should contact the developers and get them to provide a versioned release.

[BenjaminHCCarr]

In that case we need to update the required stanzas: https://github.com/caskroom/homebrew-cask/blob/master/doc/cask_language_reference/all_stanzas.md

The only required are:
version
sha256
url
name
homepage

Appcast is a full on "Optional"

I noticed that your account 404ed and all issues and PRs authored by you disappeared.

Not sure I understand what you mean by updating the required stanzas?

[BenjaminHCCarr]

I understand that appcast makes automation much easier. but there are many cask
in /usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/Casks we get:

tyr:/usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/Casks (master) benc$ ls *.rb | wc
    3663    3663   51214
tyr:/usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/Casks (master) benc$ grep -ci appcast *.rb | grep -c 1$
1991

So just about half of all Cask do not have an appcast.

[BenjaminHCCarr]

Homebrew cask has never requeired the appcast stanza; it is an optional, see: https://github.com/caskroom/homebrew-cask/blob/master/doc/cask_language_reference/all_stanzas.md

Just under half our casks don't have one at all.

[commitay]

I think this is a misunderstanding over my previous comment.

Without an appcast that matches the current release this cannot be versioned.

What I meant was this cask with the current download url cannot be versioned without an appcast.

If it had a versioned url we can use it doesn't necessarily need to have an appcast.

[BenjaminHCCarr]

abuses pipes
tyr:/usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/Casks (master) benc$ grep -ci appcast *.rb | grep 0$ | awk -F: '{print $1}' | xargs grep url | grep -v \#\{version | grep 0$ | awk -F: '{print $1}'

So yes, everything either has a versioned URL or an appcast.

And I understand the confusion you and I had about the nomenclature of the appcast stanza.

That sadly still leaves us with ~732 unverified casks.

1. using no appcast
2. using sha256 no_check

I understand this makes maintenance easier. But from an end user perspective it is frustrating. latest doesn't mean anything particularly if there is no auto_updates.

Maybe we should revisit mainlining: https://github.com/buo/homebrew-cask-upgrade

Which has made my user experience better; particularly with all of the moving-bits and re-orgs in the last year.

See #29301 for discussion about why this won't happen.

A lot of these casks casks we quite simply cannot version as there is no appcast / changelog and no versioned downloads.
