* `app`, `suite`, and `artifact no longer implemented as
synonyms for `link`
* backward-compatible code/comments removed
* creates class `Cask::Artifact::Suite`
* updates `brew cask info` to show specific artifact type
* fixes stray "Generic artifact" messages
Automatic installs - like thoughtbot's laptop script - fail when we
use Homebrew's onoe method. Using opoo (to warn) will let the
scripts complete successfully when they try to install packages that
have already been installed.
Test for downgrading AlreadyInstalledError to warning
* part of DSL 1.0 review
* `destination_path` was always a bit vague (it refers to
Cask-specific, version-specific location under
`/opt/homebrew-cask/Caskroom`)
* here renamed `staged_path` to match upcoming command verb
`brew cask stage`
* rename also intended to reduce confusion when we implement
copying as a configurable alternative to symlinking
* transitional `destination_path` methods to remain while
Casks are converted (this was documented as a part of the
DSL, and used by 39 Casks in main repo)
* unrelated variables containing "stage" recast for clarity
* was already done, but inconsistently
* this style follows homebrew Formula
* covers user-facing messages, test titles, comments
* some related minor orthography is included, such
as the consistent spelling of our project name as
"homebrew-cask"
* grammar nits
from Cask::SystemCommand.run
* stderr and stdout are now separated, though both are available
* :print_stderr is made the default, closer to previous behavior
* exit status can be read from the result object
* plist parsing is more naturally handled in the result object.
The :plist argument to the run method was removed.
* whitespace
Keeping the `link` stanza in the DSL is a mistake: it will be
confusing when combined with the ability to install by copying.
This PR retires `link` completely, and adds a generic artifact
stanza called `artifact`. (`link` is removed from the docs, but
will still work for compatibility during transition.)
This only affects one current Cask (dwarf-fortress.rb), and that
Cask may be changed to use `suite` in the future.
Replacing `link` for almost all cases.
The `link` stanza can still appear in error messages, because
under the hood, `app` is still implemented as a pure synonym
for the `link` artifact. That will change automatically when
we factor into separate artifacts.
* `zap` was previously supported as a noop for forward-compatibility
* Also adds restrictions against relative paths in `uninstall :files`
* Also documents safety conventions for `uninstall :files`
