Return the authoritative instance of the command manager.
Returns self. Allows a CommandManager
instance to stand in for the class itself.
Installs the gem dep_or_name
and all its dependencies. Returns an Array
of installed gem specifications.
If the :prerelease
option is set and there is a prerelease for dep_or_name
the prerelease version will be installed.
Unless explicitly specified as a prerelease dependency, prerelease gems that dep_or_name
depend on will not be installed.
If c-1.a depends on b-1 and a-1.a and there is a gem b-1.a available then c-1.a, b-1 and a-1.a will be installed. b-1.a will need to be installed separately.
Construct an installer object for the gem file located at path
Installs the gem and returns a loaded Gem::Specification
for the installed gem.
The gem will be installed with the following structure:
@gem_home/ cache/<gem-version>.gem #=> a cached copy of the installed gem gems/<gem-version>/... #=> extracted files specifications/<gem-version>.gemspec #=> the Gem::Specification
Installs gems for this RequestSet
using the Gem::Installer
options
.
If a block
is given an activation request
and installer
are yielded. The installer
will be nil
if a gem matching the request was already installed.
Factory method to create a Gem::Requirement
object. Input may be a Version, a String
, or nil. Intended to simplify client code.
If the input is “weird”, the default version requirement is returned.
Concatenates the new
requirements onto this requirement.
Factory method to create a Version
object. Input may be a Version
or a String
. Intended to simplify client code.
ver1 = Version.create('1.3.17') # -> (Version object) ver2 = Version.create(ver1) # -> (ver1) ver3 = Version.create(nil) # -> nil
Performs the uninstall of the gem. This removes the spec, the Gem directory, and the cached .gem file.
v
Public setter for the path component v
(with validation).
See also URI::Generic.check_path
.
require 'uri' uri = URI.parse("http://my.example.com/pub/files") uri.path = "/faq/" uri.to_s #=> "http://my.example.com/faq/"
Returns true if URI
does not have a scheme (e.g. http:// or https://) specified.
Returns attributes.
Setter for attributes val
.
Starts the CGI
process with the given environment env
and standard input and output stdin
and stdout

Formats arg
for the logger
If arg
is an Exception
, it will format the error message and the back trace.
If arg
responds to to_str, it will return it.
Otherwise it will return arg
.inspect.
A SimpleServer
only yields when you start it
Performs the standard operations for daemonizing a process. Runs a block, if given.
Starts the server and runs the block
for each connection. This method does not return until the server is stopped from a signal handler or another thread using stop
or shutdown
.
If the block raises a subclass of StandardError
the exception is logged and ignored. If an IOError
or Errno::EBADF exception is raised the exception is ignored. If an Exception
subclass is raised the exception is logged and re-raised which stops the server.
To completely shut down a server call shutdown
from ensure:
server = WEBrick::GenericServer.new # or WEBrick::HTTPServer.new begin server.start ensure server.shutdown end
Returns the conversion path of ec.
The result is an array of conversions.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP", crlf_newline: true) p ec.convpath #=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>], # [#<Encoding:UTF-8>, #<Encoding:EUC-JP>], # "crlf_newline"]
Each element of the array is a pair of encodings or a string. A pair means an encoding conversion. A string means a decorator.
In the above example, [#<Encoding:ISO-8859-1>,
