Initializes a generic gem command named command. summary is a short description displayed in ‘gem help commands`. defaults are the default options. Defaults should be mirrored in defaults_str, unless there are none.
When defining a new command subclass, use add_option to add command-line switches.
Unhandled arguments (gem names, files, etc.) are left in options[:args].
Register all the subcommands supported by the gem command.
Create the config file object. args is the list of arguments from the command line.
The following command line options are handled early here rather than later at the time most command options are processed.
--config-file, --config-file==NAMEObviously these need to be handled by the ConfigFile object to ensure we get the right config file.
--backtraceBacktrace needs to be turned on early so that errors before normal option parsing can be properly handled.
--debugEnable Ruby level debug messages. Handled early for the same reason as –backtrace.
Constructs a dependency with name and requirements. The last argument can optionally be the dependency type, which defaults to :runtime.
Creates a new installer instance.
Options are:
Alternate repository path to store .gem files in.
:local, :remote, or :both. :local only searches gems in the current directory. :remote searches only gems in Gem::sources. :both searches both.
See Gem::Installer::new.
See Gem::Installer#initialize.
Don’t install any dependencies.
Allow prerelease versions. See install.
See Gem::Installer::new and Gem::Security.
Creates a new DependencyList. If development is true, development dependencies will be included.
Creates a new Gem::Doctor that will clean up gem_repository. Only one gem repository may be cleaned at a time.
If dry_run is true no files or directories will be removed.
Creates a new SourceFetchProblem for the given source and error.
Creates a new SpecificGemNotFoundException for a gem with the given name and version. Any errors encountered when attempting to find the gem are also stored.
Creates a new SystemExitException with the given exit_code
Creates a new UnsatisfiableDependencyError for the unsatisfiable Gem::Resolver::DependencyRequest dep
Create an indexer that will index the gems in directory.
Constructs an Installer instance that will install the gem at package which can either be a path or an instance of Gem::Package. options is a Hash with the following keys:
Where to put a bin wrapper if needed.
Whether or not development dependencies should be installed.
Use /usr/bin/env in bin wrappers.
Overrides all version checks and security policy checks, except for a signed-gems-only policy.
Format the executable the same as the Ruby executable. If your Ruby is ruby18, foo_exec will be installed as foo_exec18.
Don’t raise if a dependency is missing.
The directory to install the gem into.
Use the specified security policy. See Gem::Security
Indicate that the gem should be unpacked into the users personal gem directory.
Only validate dependencies against what is in the install_dir
Install wrappers if true, symlinks if false.
An Array of arguments to pass to the extension builder process. If not set, then Gem::Command.build_args is used
Print gem post install message if true
Creates a new Gem::Package for the file at gem. gem can also be provided as an IO object.
If gem is an existing file in the old format a Gem::Package::Old will be returned.
