Initiates the SSL/TLS handshake as a client in non-blocking manner.
# emulates blocking connect begin ssl.connect_nonblock rescue IO::WaitReadable IO.select([s2]) retry rescue IO::WaitWritable IO.select(nil, [s2]) retry end
By specifying a keyword argument exception to false
, you can indicate that connect_nonblock
should not raise an IO::WaitReadable
or IO::WaitWritable
exception, but return the symbol :wait_readable
or :wait_writable
instead.
Builds extensions. Valid types of extensions are extconf.rb files, configure scripts and rakefiles or mkrf_conf files.
It is ok to remove a gemspec from the dependency list?
If removing the gemspec creates breaks a currently ok dependency, then it is NOT ok to remove the gemspec.
Sends a MOVE request to the path
and gets a response, as an HTTPResponse
object.
Sends a MOVE command to move the specified message(s) to the end of the specified destination mailbox
. The set
parameter is a number, an array of numbers, or a Range
object. The number is a message sequence number. The IMAP
MOVE extension is described in [RFC-6851].
Moves tuple
to port
.
What does this dependency require?
Lists the external (to RubyGems) requirements that must be met for this gem to work. It’s simply information for the user.
Usage:
spec.requirements << 'libmagick, v6.0' spec.requirements << 'A good graphics card'
Set
requirements to req
, ensuring it is an array.
Is remote fetching enabled?

Returns the value of the given instance variable, or nil if the instance variable is not set. The @
part of the variable name should be included for regular instance variables. Throws a NameError
exception if the supplied symbol is not valid as an instance variable name. String
arguments are converted to symbols.
class Fred def initialize(p1, p2) @a, @b = p1, p2 end end fred = Fred.new('cat', 99) fred.instance_variable_get(:@a) #=> "cat" fred.instance_variable_get("@b") #=> 99
Sets the instance variable named by symbol to the given object. This may circumvent the encapsulation intended by the author of the class, so it should be used with care. The variable does not have to exist prior to this call. If the instance variable name is passed as a string, that string is converted to a symbol.
class Fred def initialize(p1, p2) @a, @b = p1, p2 end end fred = Fred.new('cat', 99) fred.instance_variable_set(:@a, 'dog') #=> "dog" fred.instance_variable_set(:@c, 'cat') #=> "cat" fred.inspect #=> "#<Fred:0x401b3da8 @a=\"dog\", @b=99, @c=\"cat\">"
Returns true
if the given instance variable is defined in obj. String
arguments are converted to symbols.
class Fred def initialize(p1, p2) @a, @b = p1, p2 end end fred = Fred.new('cat', 99) fred.instance_variable_defined?(:@a) #=> true fred.instance_variable_defined?("@b") #=> true fred.instance_variable_defined?("@c") #=> false
Returns a list of the public instance methods defined in mod. If the optional parameter is false
, the methods of any ancestors are not included.
Returns a list of the protected instance methods defined in mod. If the optional parameter is false
, the methods of any ancestors are not included.
Returns a list of the private instance methods defined in mod. If the optional parameter is false
, the methods of any ancestors are not included.
module Mod def method1() end private :method1 def method2() end end Mod.instance_methods #=> [:method2] Mod.private_instance_methods #=> [:method1]
Similar to instance_method, searches public method only.
Raises PStore::Error
if the calling code is not in a PStore#transaction
or if the code is in a read-only PStore#transaction
.
Returns the status of the global “abort on exception” condition.
The default is false
.
When set to true
, if any thread is aborted by an exception, the raised exception will be re-raised in the main thread.
Can also be specified by the global $DEBUG flag or command line option -d
.
See also ::abort_on_exception=
.
There is also an instance level method to set this for a specific thread, see abort_on_exception
.
