Returns true if emacs mode is active. Returns false if not.
Raises NotImplementedError if the using readline library does not support.
Returns information about the most recent garbage collection.
If the optional argument, hash, is given, it is overwritten and returned. This is intended to avoid probe effect.
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.

Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:
def_delegators :@records, :size, :<<, :map def_delegator :@records, :size def_delegator :@records, :<< def_delegator :@records, :map
Define method as delegator instance method with an optional alias name ali. Method calls to ali will be delegated to accessor.method. accessor should be a method name, instance variable name, or constant name. Use the full path to the constant if providing the constant name. Returns the name of the method defined.
class MyQueue CONST = 1 extend Forwardable attr_reader :queue def initialize @queue = [] end def_delegator :@queue, :push, :mypush def_delegator 'MyQueue::CONST', :to_i end q = MyQueue.new q.mypush 42 q.queue #=> [42] q.push 23 #=> NoMethodError q.to_i #=> 1
Shortcut for defining multiple delegator methods, but with no provision for using a different name. The following two code samples have the same effect:
def_delegators :@records, :size, :<<, :map def_delegator :@records, :size def_delegator :@records, :<< def_delegator :@records, :map
Defines a method method which delegates to accessor (i.e. it calls the method of the same name in accessor). If new_name is provided, it is used as the name for the delegate method. Returns the name of the method defined.
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.
Returns a list of paths matching glob from the latest gems that can be used by a gem to pick up features from other gems. For example:
Gem.find_latest_files('rdoc/discover').each do |path| load path end
if check_load_path is true (the default), then find_latest_files also searches $LOAD_PATH for files as well as gems.
Unlike find_files, find_latest_files will return only files from the latest version of a gem.
Return the length of the hash value in bytes.
Return the length of the hash value (the digest) in bytes.
Digest::SHA256.new.digest_length * 8 # => 256 Digest::SHA384.new.digest_length * 8 # => 384 Digest::SHA512.new.digest_length * 8 # => 512
For example, digests produced by Digest::SHA256 will always be 32 bytes (256 bits) in size.
ptr.to_str => string ptr.to_str(len) => string
Returns the pointer contents as a string.
When called with no arguments, this method will return the contents with the length of this pointer’s size.
When called with len, a string of len bytes will be returned.
See to_s
Returns the output size of the digest, i.e. the length in bytes of the final message digest result.
digest = OpenSSL::Digest.new('SHA1') puts digest.digest_length # => 20
Called when a map ends
Called when the YAML stream ends
Write value to a registry value named name.
The value type is REG_SZ(write_s), REG_DWORD(write_i), or REG_BINARY(write_bin).
Returns true if the stream is finished.
See Zlib::GzipReader documentation for a description.
