* convert existing Cask:: namespace to Hbc::
* move Homebrew-fork code under Hbc::
* move freestanding classes such as Tty and TopologicalHash under Hbc::
* recast HOMEBREW_CASK_ constants as HBC_
* modify our Homebrew Formula for backward compatibility
* devscripts and dev docs
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
* 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
Including the case where a Cask is already installed.
Always continue installing when multiple Casks are specified,
only raising an exception at the end of the command (if some
portion of the attempted install actions failed). Never
exit with an error code if "already installed" was the only
problem seen during the run.
Also tweak error messages.
Fixes#1347, #2677, #4785
Required disabling two tests regarding suggestions on Cask
spelling errors.
