Synonym for CGI.unescapeElement(str)

A wrapper class to use a StringIO object as the body and switch to a TempFile when the passed threshold is passed. Initialize the data from the query.

Handles multipart forms (in particular, forms that involve file uploads). Reads query parameters in the @params field, and cookies into @cookies.

Displays a warning statement to the warning output location. Asks a question if given.

Return a hash for statistics generated for the --yjit-stats command line option. Return nil when option is not passed or unavailable. If a symbol argument is provided, return only the value for the named stat. If any other type is provided, raises TypeError.

Returns a list of the undefined instance methods defined in mod. The undefined methods of any ancestors are not included.

Unpacks sockaddr into port and ip_address.

sockaddr should be a string or an addrinfo for AF_INET/AF_INET6.

sockaddr = Socket.sockaddr_in(80, "127.0.0.1")
p sockaddr #=> "\x02\x00\x00P\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00"
p Socket.unpack_sockaddr_in(sockaddr) #=> [80, "127.0.0.1"]

Packs path as an AF_UNIX sockaddr string.

Socket.sockaddr_un("/tmp/sock") #=> "\x01\x00/tmp/sock\x00\x00..."

Returns whether the [position] is at the beginning of a line; that is, at the beginning of the [stored string] or immediately after a newline:

scanner = StringScanner.new(MULTILINE_TEXT)
scanner.string
# => "Go placidly amid the noise and haste,\nand remember what peace there may be in silence.\n"
scanner.pos                # => 0
scanner.beginning_of_line? # => true

scanner.scan_until(/,/)    # => "Go placidly amid the noise and haste,"
scanner.beginning_of_line? # => false

scanner.scan(/\n/)         # => "\n"
scanner.beginning_of_line? # => true

scanner.terminate
scanner.beginning_of_line? # => true

scanner.concat('x')
scanner.terminate
scanner.beginning_of_line? # => false

StringScanner#bol? is an alias for StringScanner#beginning_of_line?.

Invoked as a callback whenever a singleton method is undefined in the receiver.

module Chatty
  def Chatty.singleton_method_undefined(id)
    puts "Undefining #{id.id2name}"
  end
  def Chatty.one()   end
  class << self
     undef_method(:one)
  end
end

produces:

Undefining one

Establishes proc on thr as the handler for tracing, or disables tracing if the parameter is nil.

See Kernel#set_trace_func.

Adds proc as a handler for tracing.

See Thread#set_trace_func and Kernel#set_trace_func.

Establishes proc as the handler for tracing, or disables tracing if the parameter is nil.

Note: this method is obsolete, please use TracePoint instead.

proc takes up to six parameters:

• an event name string

• a filename string

• a line number

• a method name symbol, or nil

• a binding, or nil

• the class, module, or nil

proc is invoked whenever an event occurs.

Events are:

"c-call"

call a C-language routine

"c-return"

return from a C-language routine

"call"

call a Ruby method

"class"

start a class or module definition

"end"

finish a class or module definition

"line"

execute code on a new line

"raise"

raise an exception

"return"

return from a Ruby method

Tracing is disabled within the context of proc.

class Test
  def test
    a = 1
    b = 2

set_trace_func proc { |event, file, line, id, binding, class_or_module|
  printf "%8s %s:%-2d %16p %14p\n", event, file, line, id, class_or_module
}
t = Test.new
t.test

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.

Counts objects for each T_IMEMO type.

This method is only for MRI developers interested in performance and memory usage of Ruby programs.

It returns a hash as:

{:imemo_ifunc=>8,
 :imemo_svar=>7,
 :imemo_cref=>509,
 :imemo_memo=>1,
 :imemo_throw_data=>1}

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 symbol objects.

This method is only expected to work with C Ruby.

Load the document contained in filename. Returns the yaml contained in filename as a Ruby object, or if the file is empty, it returns the specified fallback return value, which defaults to false.

NOTE: This method *should not* be used to parse untrusted documents, such as YAML documents that are supplied via user input. Instead, please use the safe_load_file method.
