Obsoleted by new form `container :nested`.
This PR only removes DSL support; the job is incomplete.
Internally, `container :nested` is still implemented as a
pseudo-artifact named `nested_container`. The intention
is to factor nested containers out of artifacts.
This takes the form of a horrible hack: DSL version numbers may
end with "test", *eg* ":v1test". Such Casks are mapped to class
`TestCask` instead of class `Cask`.
The intention is that all of this logic will be removed when
Casks are migrated away from separate classes.
Tests driven by RSpec are still todo.
`caskroom_only` was never documented. Its original purpose was
obsoleted in #4865, and its use has been recently been reduced to
two Casks.
This PR
* continues the rationalization of naming by changing `caskroom_only`
to `stage_only`. "stage" is the verb for "make a copy under the
caskroom directory"
* documents `stage_only`
* adds tests for `stage_only`
* validates the argument to `stage_only`
* gives sensible output in `brew cask info` for `stage_only` Casks
* enforces that `stage_only` cannot coexist with any activatable
artifacts
`caskroom_only` is still supported for backward compatibility,
but should be removed before 0.50.0.
* `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
* `checklinks` is a very simple implementation useful only for development purposes
* it has no test coverage, only one line of documentation
* users regularly experiment with it and break it, especially
`brew cask checklinks` with no arguments, which tests all Tapped Casks
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
