Returns the parameter information of this proc. If the lambda keyword is provided and not nil, treats the proc as a lambda if true and as a non-lambda if false.

prc = proc{|x, y=42, *other|}
prc.parameters  #=> [[:opt, :x], [:opt, :y], [:rest, :other]]
prc = lambda{|x, y=42, *other|}
prc.parameters  #=> [[:req, :x], [:opt, :y], [:rest, :other]]
prc = proc{|x, y=42, *other|}
prc.parameters(lambda: true)  #=> [[:req, :x], [:opt, :y], [:rest, :other]]
prc = lambda{|x, y=42, *other|}
prc.parameters(lambda: false) #=> [[:opt, :x], [:opt, :y], [:rest, :other]]

Returns the parameter information of this method.

def foo(bar); end
method(:foo).parameters #=> [[:req, :bar]]

def foo(bar, baz, bat, &blk); end
method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:req, :bat], [:block, :blk]]

def foo(bar, *args); end
method(:foo).parameters #=> [[:req, :bar], [:rest, :args]]

def foo(bar, baz, *args, &blk); end
method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:rest, :args], [:block, :blk]]

Returns the parameter information of this method.

def foo(bar); end
method(:foo).parameters #=> [[:req, :bar]]

def foo(bar, baz, bat, &blk); end
method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:req, :bat], [:block, :blk]]

def foo(bar, *args); end
method(:foo).parameters #=> [[:req, :bar], [:rest, :args]]

def foo(bar, baz, *args, &blk); end
method(:foo).parameters #=> [[:req, :bar], [:req, :baz], [:rest, :args], [:block, :blk]]

Return the parameters definition of the method or block that the current hook belongs to. Format is the same as for Method#parameters

Generates new parameters for the algorithm. algo_name is a String that represents the algorithm. The optional argument options is a Hash that specifies the options specific to the algorithm. The order of the options can be important.

A block can be passed optionally. The meaning of the arguments passed to the block varies depending on the implementation of the algorithm. The block may be called once or multiple times, or may not even be called.

For the supported options, see the documentation for the ‘openssl genpkey’ utility command.

Example

pkey = OpenSSL::PKey.generate_parameters("DSA", "dsa_paramgen_bits" => 2048)
p pkey.p.num_bits #=> 2048

def comment_targets: () -> Array[Node | Location]

def comment_targets: () -> Array[Node | Location]

Returns the fractional part of the day in range (Rational(0, 1)…Rational(1, 1)):

DateTime.new(2001,2,3,12).day_fraction # => (1/2)

Returns the value that determines whether illegal input is to be handled; used for parsing; see {Option liberal_parsing}:

CSV.new('').liberal_parsing? # => false

Controls tracing of assignments to global variables. The parameter symbol identifies the variable (as either a string name or a symbol identifier). cmd (which may be a string or a Proc object) or block is executed whenever the variable is assigned. The block or Proc object receives the variable’s new value as a parameter. Also see Kernel::untrace_var.

trace_var :$_, proc {|v| puts "$_ is now '#{v}'" }
$_ = "hello"
$_ = ' there'

produces:

$_ is now 'hello'
$_ is now ' there'

Removes tracing for the specified command on the given global variable and returns nil. If no command is specified, removes all tracing for that variable and returns an array containing the commands actually removed.

How String Gem paths should be split. Overridable for esoteric platforms.

Adds DidYouMean functionality to an error using a given spell checker

Returns whether or not the given entry point func can be found within lib. If func is nil, the main() entry point is used by default. If found, it adds the library to list of libraries to be used when linking your extension.

If headers are provided, it will include those header files as the header files it looks in when searching for func.

The real name of the library to be linked can be altered by --with-FOOlib configuration option.

Returns whether or not the entry point func can be found within the library lib in one of the paths specified, where paths is an array of strings. If func is nil , then the main() function is used as the entry point.

If lib is found, then the path it was found on is added to the list of library paths searched and linked against.

returns array of WIN32OLE_PARAM object corresponding with method parameters.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
p method.params # => [Filename, FileFormat, Password, WriteResPassword,
                      ReadOnlyRecommended, CreateBackup, AccessMode,
                      ConflictResolution, AddToMru, TextCodepage,
                      TextVisualLayout]

Changes the parameters of the deflate stream to allow changes between different types of data that require different types of compression. Any unprocessed data is flushed before changing the params.

See Zlib::Deflate.new for a description of level and strategy.

Returns true if URI is hierarchical.

Description

URI has components listed in order of decreasing significance from left to right, see RFC3986 tools.ietf.org/html/rfc3986 1.2.3.

Usage

require 'uri'

uri = URI.parse("http://my.example.com/")
uri.hierarchical?
#=> true
uri = URI.parse("mailto:joe@example.com")
uri.hierarchical?
#=> false
