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.
Create an exception with class klass
and message
returns the directory nesting of the extension, ignoring the first part, so “ext/foo/bar/Cargo.toml” becomes “foo/bar”
Add the install/update options to the option parser.
Add the –update-sources option
Returns self
modulo other
as a real number.
For integer n
and real number r
, these expressions are equivalent:
n % r n-r*(n/r).floor n.divmod(r)[1]
See Numeric#divmod
.
Examples:
10 % 2 # => 0 10 % 3 # => 1 10 % 4 # => 2 10 % -2 # => 0 10 % -3 # => -2 10 % -4 # => -2 10 % 3.0 # => 1.0 10 % Rational(3, 1) # => (1/1)
Returns self
modulo other
as a real number.
Of the Core and Standard Library classes, only Rational
uses this implementation.
For Rational
r
and real number n
, these expressions are equivalent:
r % n r-n*(r/n).floor r.divmod(n)[1]
See Numeric#divmod
.
Examples:
r = Rational(1, 2) # => (1/2) r2 = Rational(2, 3) # => (2/3) r % r2 # => (1/2) r % 2 # => (1/2) r % 2.0 # => 0.5 r = Rational(301,100) # => (301/100) r2 = Rational(7,5) # => (7/5) r % r2 # => (21/100) r % -r2 # => (-119/100) (-r) % r2 # => (119/100) (-r) %-r2 # => (-21/100)
Returns self
modulo other
as a float.
For float f
and real number r
, these expressions are equivalent:
f % r f-r*(f/r).floor f.divmod(r)[1]
See Numeric#divmod
.
Examples:
10.0 % 2 # => 0.0 10.0 % 3 # => 1.0 10.0 % 4 # => 2.0 10.0 % -2 # => 0.0 10.0 % -3 # => -2.0 10.0 % -4 # => -2.0 10.0 % 4.0 # => 2.0 10.0 % Rational(4, 1) # => 2.0
Unpacks sockaddr into path.
sockaddr should be a string or an addrinfo for AF_UNIX
.
sockaddr = Socket.sockaddr_un("/tmp/sock") p Socket.unpack_sockaddr_un(sockaddr) #=> "/tmp/sock"
Counts objects size (in bytes) for each type.
Note that this information is incomplete. You need to deal with this information as only a HINT. Especially, total size of T_DATA may be wrong.
It returns a hash as:
{:TOTAL=>1461154, :T_CLASS=>158280, :T_MODULE=>20672, :T_STRING=>527249, ...}
If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.
The contents of the returned hash is implementation defined. It may be changed in future.
This method is only expected to work with C Ruby.
Counts objects for each T_DATA
type.
This method is only for MRI developers interested in performance and memory usage of Ruby programs.
It returns a hash as:
{RubyVM::InstructionSequence=>504, :parser=>5, :barrier=>6, :mutex=>6, Proc=>60, RubyVM::Env=>57, Mutex=>1, Encoding=>99, ThreadGroup=>1, Binding=>1, Thread=>1, RubyVM=>1, :iseq=>1, Random=>1, ARGF.class=>1, Data=>1, :autoload=>3, Time=>2} # T_DATA objects existing at startup on r32276.
If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.
The contents of the returned hash is implementation specific and may change in the future.
In this version, keys are Class
object or Symbol
object.
If object is kind of normal (accessible) object, the key is Class
object. If object is not a kind of normal (internal) object, the key is symbol name, registered by rb_data_type_struct.
This method is only expected to work with C Ruby.
The number of paths in the +$LOAD_PATH+ from activated gems. Used to prioritize -I
and ENV['RUBYLIB']
entries during require
.
Returns a String
containing the API compatibility version of Ruby
Returns the latest release version of RubyGems.
Returns the version of the latest release-version of gem name
Calls wait repeatedly until the given block yields a truthy value.
Returns major version.
tobj = WIN32OLE::Type.new('Microsoft Word 10.0 Object Library', 'Documents') puts tobj.major_version # => 8
Returns minor version.
tobj = WIN32OLE::Type.new('Microsoft Word 10.0 Object Library', 'Documents') puts tobj.minor_version # => 2
