Return the current value whenever the stanza method is called
without arguments, including when the stanza has no value. Do
not attempt to construct an instance with no arguments (which
typically throws an exception).
Incidental comment re: depends_on
Refs #7880
* to match phrasing in our documentation
* to distinguish against the Cask `version` (of which there may
be more than one in the future)
* better fit with symbolic release names eg `:yosemite`
* `MacOS.release` itself is intentionally undocumented pending
the next code release
* accepts a Boolean value
* replaces the never-documented `postflight` methods `enable_accessibility_access` /
`disable_accessibility_access` (`remove_accessibility_access`)
* declarative: unlike the `postflight` approach, does not have to be
invoked in two places
* de-document obsolete form `caveats` / `assistive_devices`
* bump Travis seed to avoid false test failures
When invoking a `SystemCommand` with `:must_succeed => false`, the `SystemCommand::Result` class would mistake a `Process.Status` object for a `Fixnum`.
This commit fixes this by instantiating `Result` with the actual status code as a number.
This fixes an issue where both the `--debug` option and the `brew cask _dump` command would fail on Ruby 1.8.7 when the Cask has an `installer` stanza, e. g. `adobe-air`.
Class names are now completely hidden from the user. This
commit works by adding a prefix to all Cask class names, which
is considered to be an ugly transitional hack on the way to
representing individual Casks as instances.
* always coerce `:macos` value to array; simplify code
* remove warning comments about unset values
* doc explicitly that requirements are covered as well as dependencies
* doc that `depends_on` is not consulted until `install` time
* in docs and code, say "release" instead of "version" for the :macos release
* todo: provide our own variable styled "release" to use in Casks, instead of Homebrew's `MacOS.Version`
* doc that symbols are preferred for `:macos` over strings in Casks (interally, all are converted to idential `Gem::Version` objects)
* doc: remove `os_version_only` from `cask_language_deltas.md`
* doc: improve internal links
* doc: recast OS X release symbol list as table
* doc: (incidental) regularize orthography of Formula and Cask
* Fill in the functionality for the `depends_on :macos` stub
* de-document `caveats` method `os_version_only`
* clean up some related docs re: version strings
* add `depends_on_test.rb`
* clarify some related `depends_on :formula` doc, tests, and code
* formatting in test Casks
