For forward-compatibility; intentionally left undocumented.
The `license` stanza is not free-form. There is a limited
set of valid symbols, of which the argument must be a member.
(The set will later be documented, and probably needs amendments.)
Version numbers and variants of licenses are intentionally
ommitted. The use-case for `license` is filtering and listing
of Casks. We want to avoid becoming a detailed repository of
application descriptions: that information can be found at the
`homepage` URL.
Fixes#4677. This change is necessitated by Homebrew's recent
switch to Ruby 2.x. These changes may be incomplete and/or
may not work well with Ruby 1.8. Travis should test Ruby 1.8
compatibility.
Fixes#2997. Interface is optional DSL stanza `container_type`.
This should only be used in rare instances. It is needed for the
case of a naked executable which should not be unpacked.
Appcasts are a standard way for applications to publish
information about available updates via RSS. Sparkle and
other update frameworks are built upon appcasts.
In a quick test, appcasts were found for 188/360 Casks examined.
This PR adds an optional `appcast` stanza, but does not add
`appcast` to any Cask or make use of the info in any way. It is
intentionally left undocumented.
- add new file "cask/utils.rb" analogous to "utils.rb" in Homebrew
- define odebug and odumpcask, analogs of ohai and friends, but
which only give output when --debug is in effect
- move the debug setting from an instance variable in Cask::CLI
to a method Cask.debug, defined in "lib/cask/options.rb", which
was added in #2276. (Perhaps options.rb should be merged back
into Cask::CLI).
- sprinkle odebug statements liberally throughout the codebase
- update tests
