Handle BasicObject
instances
The block passed to this method will be called just before running the RDoc
generator. It is allowed to modify RDoc::Task
attributes inside the block.
Iterates the given block for each element with an arbitrary object given, and returns the initially given object.
If no block is given, returns an enumerator.
evens = (1..10).each_with_object([]) { |i, a| a << i*2 } #=> [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]
Sets a list of quote characters which can cause a word break.
Raises NotImplementedError
if the using readline library does not support.

Returns information about object moved in the most recent GC compaction.
The returned hash has two keys :considered and :moved. The hash for :considered lists the number of objects that were considered for movement by the compactor, and the :moved hash lists the number of objects that were actually moved. Some objects can’t be moved (maybe they were pinned) so these numbers can be used to calculate compaction efficiency.
Set
the default id conversion object.
This is expected to be an instance such as DRb::DRbIdConv
that responds to to_id
and to_obj
that can convert objects to and from DRb
references.
See DRbServer#default_id_conv.

Returns whether or not the struct of type type
contains member
. If it does not, or the struct type can’t be found, then false is returned. You may optionally specify additional headers
in which to look for the struct (in addition to the common header files).
If found, a macro is passed as a preprocessor constant to the compiler using the type name and the member name, in uppercase, prepended with HAVE_
.
For example, if have_struct_member('struct foo', 'bar')
returned true, then the HAVE_STRUCT_FOO_BAR
preprocessor macro would be passed to the compiler.
HAVE_ST_BAR
is also defined for backward compatibility.
Quietly ensure the Gem directory dir
contains all the proper subdirectories. If we can’t create a directory due to a permission problem, then we will silently continue.
If mode
is given, missing directories are created with this mode.
World-writable directories will never be created.
@return [Object] most up-to-date dependency in the possibility set
Iterates the given block for each element with an index, which starts from offset
. If no block is given, returns a new Enumerator
that includes the index, starting from offset
offset

Returns a new lazy enumerator with the concatenated results of running block
once for every element in the lazy enumerator.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x
returned by block
is decomposed if either of the following conditions is true:
x
responds to both each and force, which means that x
is a lazy enumerator.
x
is an array or responds to to_ary.
Otherwise, x
is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force #=> [{:a=>1}, {:b=>2}]
Like Enumerable#select
, but chains operation to be lazy-evaluated.
Like Enumerable#filter_map
, but chains operation to be lazy-evaluated.
(1..).lazy.filter_map { |i| i * 2 if i.even? }.first(5) #=> [4, 8, 12, 16, 20]
Sets the length of the authentication tag to be generated or to be given for AEAD ciphers that requires it as in input parameter. Note that not all AEAD ciphers support this method.
In OCB mode, the length must be supplied both when encrypting and when decrypting, and must be before specifying an IV.
Sets the length of the plaintext / ciphertext message that will be processed in CCM mode. Make sure to call this method after key=
and iv=
have been set, and before auth_data=
.
Only call this method after calling Cipher#encrypt
or Cipher#decrypt
.
Set
the default value for the :argc_limit option.
See new(). The initial default value is 256.
Set
the default value for the :load_limit option.
See new(). The initial default value is 25 MB.
Check that a method is callable via dRuby.
obj
is the object we want to invoke the method on. msg_id
is the method name, as a Symbol
.
If the method is an insecure method (see insecure_method?
) a SecurityError
is thrown. If the method is private or undefined, a NameError
is thrown.
