The UriFormatter handles URIs from user-input and escaping.

uf = Gem::UriFormatter.new 'example.com'

p uf.normalize #=> 'http://example.com'

Random number formatter.

Formats generated random numbers in many manners. When 'random/formatter' is required, several methods are added to empty core module Random::Formatter, making them available as Random’s instance and module methods.

Standard library SecureRandom is also extended with the module, and the methods described below are available as a module methods in it.

Examples

Generate random hexadecimal strings:

require 'random/formatter'

prng = Random.new
prng.hex(10) #=> "52750b30ffbc7de3b362"
prng.hex(10) #=> "92b15d6c8dc4beb5f559"
prng.hex(13) #=> "39b290146bea6ce975c37cfc23"
# or just
Random.hex #=> "1aed0c631e41be7f77365415541052ee"

Generate random base64 strings:

prng.base64(10) #=> "EcmTPZwWRAozdA=="
prng.base64(10) #=> "KO1nIU+p9DKxGg=="
prng.base64(12) #=> "7kJSM/MzBJI+75j8"
Random.base64(4) #=> "bsQ3fQ=="

Generate random binary strings:

prng.random_bytes(10) #=> "\016\t{\370g\310pbr\301"
prng.random_bytes(10) #=> "\323U\030TO\234\357\020\a\337"
Random.random_bytes(6) #=> "\xA1\xE6Lr\xC43"

Generate alphanumeric strings:

prng.alphanumeric(10) #=> "S8baxMJnPl"
prng.alphanumeric(10) #=> "aOxAg8BAJe"
Random.alphanumeric #=> "TmP9OsJHJLtaZYhP"

Generate UUIDs:

prng.uuid #=> "2d931510-d99f-494a-8c67-87feb05e1594"
prng.uuid #=> "bad85eb9-0713-4da7-8d36-07a8e4b00eab"
Random.uuid #=> "f14e0271-de96-45cc-8911-8910292a42cd"

All methods are available in the standard library SecureRandom, too:

SecureRandom.hex #=> "05b45376a30c67238eb93b16499e50cf"

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

Class for representing HTTP method PATCH:

require 'net/http'
uri = URI('http://example.com')
hostname = uri.hostname # => "example.com"
uri.path = '/posts'
req = Net::HTTP::Patch.new(uri) # => #<Net::HTTP::Patch PATCH>
req.body = '{"title": "foo","body": "bar","userId": 1}'
req.content_type = 'application/json'
res = Net::HTTP.start(hostname) do |http|
  http.request(req)
end

See Request Headers.

Properties:

• Request body: yes.

• Response body: yes.

• Safe: no.

• Idempotent: no.

• Cacheable: no.

Class for representing WebDAV method PROPPATCH:

require 'net/http'
uri = URI('http://example.com')
hostname = uri.hostname # => "example.com"
req = Net::HTTP::Proppatch.new(uri) # => #<Net::HTTP::Proppatch PROPPATCH>
res = Net::HTTP.start(hostname) do |http|
  http.request(req)
end

Generator

Enumerator::Chain is a subclass of Enumerator, which represents a chain of enumerables that works as a single enumerator.

This type of objects can be created by Enumerable#chain and Enumerator#+.

Raised by Encoding and String methods when the source encoding is incompatible with the target encoding.

This exception is raised if a generator or unparser error occurs.

OpenSSL::HMAC allows computing Hash-based Message Authentication Code (HMAC). It is a type of message authentication code (MAC) involving a hash function in combination with a key. HMAC can be used to verify the integrity of a message as well as the authenticity.

OpenSSL::HMAC has a similar interface to OpenSSL::Digest.

HMAC-SHA256 using one-shot interface

key = "key"
data = "message-to-be-authenticated"
mac = OpenSSL::HMAC.hexdigest("SHA256", key, data)
#=> "cddb0db23f469c8bf072b21fd837149bd6ace9ab771cceef14c9e517cc93282e"

HMAC-SHA256 using incremental interface

data1 = File.binread("file1")
data2 = File.binread("file2")
key = "key"
hmac = OpenSSL::HMAC.new(key, 'SHA256')
hmac << data1
hmac << data2
mac = hmac.digest

Subclasses ‘BadAlias` for backwards compatibility

Thrown when PTY::check is called for a pid that represents a process that has exited.

Socket::AncillaryData represents the ancillary data (control information) used by sendmsg and recvmsg system call. It contains socket family, control message (cmsg) level, cmsg type and cmsg data.

Subclass of Zlib::Error when zlib returns a Z_DATA_ERROR.

Usually if a stream was prematurely freed.

Zlib::Deflate is the class for compressing data. See Zlib::ZStream for more information.

Zlib:Inflate is the class for decompressing compressed data. Unlike Zlib::Deflate, an instance of this class is not able to duplicate (clone, dup) itself.

Objects of class File::Stat encapsulate common status information for File objects. The information is recorded at the moment the File::Stat object is created; changes made to the file after that point will not be reflected. File::Stat objects are returned by IO#stat, File::stat, File#lstat, and File::lstat. Many of these methods return platform-specific values, and not all values are meaningful on all systems. See also Kernel#test.
