methods when the string being transcoded contains a byte invalid for the either the source or target encoding.
AbstractSyntaxTree
provides methods to parse Ruby code into abstract syntax trees. The nodes in the tree are instances of RubyVM::AbstractSyntaxTree::Node
.
This module is MRI specific as it exposes implementation details of the MRI abstract syntax tree.
This module is experimental and its API is not stable, therefore it might change without notice. As examples, the order of children nodes is not guaranteed, the number of children nodes might change, there is no way to access children nodes by name, etc.
If you are looking for a stable API or an API working under multiple Ruby implementations, consider using the parser gem or Ripper
. If you would like to make RubyVM::AbstractSyntaxTree
stable, please join the discussion at bugs.ruby-lang.org/issues/14844.
This module provides instance methods for a digest implementation object to calculate message digest values.

OpenSSL
IO
buffering mix-in module.
This module allows an OpenSSL::SSL::SSLSocket
to behave like an IO
.
You typically won’t use this module directly, you can see it implemented in OpenSSL::SSL::SSLSocket
.
Random
number formatter. Formats generated random numbers in many manners.
Generate random hexadecimal strings:
require 'random/formatter' prng.hex(10) #=> "52750b30ffbc7de3b362" prng.hex(10) #=> "92b15d6c8dc4beb5f559" prng.hex(13) #=> "39b290146bea6ce975c37cfc23"
Generate random base64 strings:
prng.base64(10) #=> "EcmTPZwWRAozdA==" prng.base64(10) #=> "KO1nIU+p9DKxGg==" prng.base64(12) #=> "7kJSM/MzBJI+75j8"
Generate random binary strings:
prng.random_bytes(10) #=> "\016\t{\370g\310pbr\301" prng.random_bytes(10) #=> "\323U\030TO\234\357\020\a\337"
Generate alphanumeric strings:
prng.alphanumeric(10) #=> "S8baxMJnPl" prng.alphanumeric(10) #=> "aOxAg8BAJe"
Generate UUIDs:
prng.uuid #=> "2d931510-d99f-494a-8c67-87feb05e1594" prng.uuid #=> "bad85eb9-0713-4da7-8d36-07a8e4b00eab"
Generate a random number in the given range as Random
does
prng.random_number #=> 0.5816771641321361 prng.random_number(1000) #=> 485 prng.random_number(1..6) #=> 3 prng.rand #=> 0.5816771641321361 prng.rand(1000) #=> 485 prng.rand(1..6) #=> 3

Module
that defines the default UserInteraction
. Any class including this module will have access to the ui
method that returns the default UI.
UserInteraction
allows RubyGems to interact with the user through standard methods that can be replaced with more-specific UI methods for different displays.
Since UserInteraction
dispatches to a concrete UI class you may need to reference other classes for specific behavior such as Gem::ConsoleUI
or Gem::SilentUI
.
Example:
class X include Gem::UserInteraction def get_answer n = ask("What is the meaning of life?") end end
This class represents a YAML Mapping.
A Psych::Nodes::Mapping
node may have 0 or more children, but must have an even number of children. Here are the valid children a Psych::Nodes::Mapping
node may have:
