Results for: "to_proc"

Returns the authentication code as a hex-encoded string. The digest parameter specifies the digest algorithm to use. This may be a String representing the algorithm name or an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'

hmac = OpenSSL::HMAC.hexdigest('SHA1', key, data)
#=> "de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9"

Gets the parsable form of the current configuration.

Given the following configuration being created:

config = OpenSSL::Config.new
  #=> #<OpenSSL::Config sections=[]>
config['default'] = {"foo"=>"bar","baz"=>"buz"}
  #=> {"foo"=>"bar", "baz"=>"buz"}
puts config.to_s
  #=> [ default ]
  #   foo=bar
  #   baz=buz

You can parse get the serialized configuration using to_s and then parse it later:

serialized_config = config.to_s
# much later...
new_config = OpenSSL::Config.parse(serialized_config)
  #=> #<OpenSSL::Config sections=["default"]>
puts new_config
  #=> [ default ]
      foo=bar
      baz=buz

returns the socket option data as a string.

p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).data
#=> "\x01\x00\x00\x00"

Short representation of the buffer. It includes the address, size and symbolic flags. This format is subject to change.

puts IO::Buffer.new(4) # uses to_s internally
# #<IO::Buffer 0x000055769f41b1a0+4 INTERNAL>

Returns an Array with 14 elements representing the instruction sequence with the following data:

magic

A string identifying the data format. Always YARVInstructionSequence/SimpleDataFormat.

major_version

The major version of the instruction sequence.

minor_version

The minor version of the instruction sequence.

format_type

A number identifying the data format. Always 1.

misc

A hash containing:

:arg_size

the total number of arguments taken by the method or the block (0 if iseq doesn’t represent a method or block)

:local_size

the number of local variables + 1

:stack_max

used in calculating the stack depth at which a SystemStackError is thrown.

label

The name of the context (block, method, class, module, etc.) that this instruction sequence belongs to.

<main> if it’s at the top level, <compiled> if it was evaluated from a string.

path

The relative path to the Ruby file where the instruction sequence was loaded from.

<compiled> if the iseq was evaluated from a string.

absolute_path

The absolute path to the Ruby file where the instruction sequence was loaded from.

nil if the iseq was evaluated from a string.

first_lineno

The number of the first source line where the instruction sequence was loaded from.

type

The type of the instruction sequence.

Valid values are :top, :method, :block, :class, :rescue, :ensure, :eval, :main, and plain.

locals

An array containing the names of all arguments and local variables as symbols.

params

An Hash object containing parameter information.

More info about these values can be found in vm_core.h.

catch_table

A list of exceptions and control flow operators (rescue, next, redo, break, etc.).

bytecode

An array of arrays containing the instruction names and operands that make up the body of the instruction sequence.

Note that this format is MRI specific and version dependent.

Same as format.

Returns a new 6-element array, consisting of the label, user CPU time, system CPU time, children’s user CPU time, children’s system CPU time and elapsed real time.

Returns a hash containing the same data as ‘to_a`.

Convert the Cookie to its string representation.

Returns the new Hash formed by adding each header-value pair in self as a key-value pair in the Hash.

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
row = table[0]
row.to_h # => {"Name"=>"foo", "Value"=>"0"}

Header order is preserved, but repeated headers are ignored:

source = "Name,Name,Name\nFoo,Bar,Baz\n"
table = CSV.parse(source, headers: true)
row = table[0]
row.to_h # => {"Name"=>"Foo"}

Returns the table as an Array of Arrays; the headers are in the first row:

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
table.to_a # => [["Name", "Value"], ["foo", "0"], ["bar", "1"], ["baz", "2"]]

Returns a String representation of the URI::FTP.
