VERSION =

This will always be up to date with the current version of Vagrant, since it is used to generate the gemspec and is also the source of the version for vagrant -v

DEFAULT_SERVER_URL =

This is the default endpoint of the Vagrant Cloud in use. API calls will be made to this for various functions of Vagrant that may require remote access.

Returns:

  • (String)

THREAD_MAX_JOIN_TIMEOUT =
Note:

This is not the maxium time for a thread to complete.

Max number of seconds to wait for joining an active thread.

Class Method Summary collapse

Class Method Details

.configure(version, &block) ⇒ Object

Configure a Vagrant environment. The version specifies the version of the configuration that is expected by the block. The block, based on that version, configures the environment.

Note that the block isn't run immediately. Instead, the configuration block is stored until later, and is run when an environment is loaded.

Parameters:

  • version (String) —

    Version of the configuration

.enable_resolv_replace ⇒ boolean

Use Ruby Resolv in place of libc

Returns:

  • (boolean) —

    enabled or not

    end
  else
    false
  end
end

.global_lock ⇒ Object

This holds a global lock for the duration of the block. This should be invoked around anything that is modifying process state (such as environmental variables).

.has_plugin?(name, version = nil) ⇒ Boolean

This checks if a plugin with the given name is available (installed and enabled). This can be used from the Vagrantfile to easily branch based on plugin availability.

Returns:

.original_env ⇒ Hash

          h[key] = v
        end
      end
    end
  end
end

.plugin(version, component = nil) ⇒ Class

Returns a superclass to use when creating a plugin for Vagrant. Given a specific version, this returns a proper superclass to use to register plugins for that version.

Optionally, if you give a specific component, then it will return the proper superclass for that component as well.

Plugins and plugin components should subclass the classes returned by this method. This method lets Vagrant core control these superclasses and change them over time without affecting plugins. For example, if the V1 superclass happens to be "Vagrant::V1," future versions of Vagrant may move it to "Vagrant::Plugins::V1" and plugins will not be affected.

Parameters:

  • version (String)
  • component (String) (defaults to: nil)

Returns:

  • (Class)

Raises:

  • (ArgumentError)

end

.require_version(*requirements) ⇒ Object

This allows a Vagrantfile to specify the version of Vagrant that is required. You can specify a list of requirements which will all be checked against the running Vagrant version.

This should be specified at the top of any Vagrantfile.

Examples are shown below:

Vagrant.require_version(">= 1.3.5") Vagrant.require_version(">= 1.3.5", "< 1.4.0") Vagrant.require_version("~> 1.3.5")
