Results for: "Pathname"

Outputs code with highlighted lines

Whatever is passed to this class will be rendered even if it is “marked invisible” any filtering of output should be done before calling this class.

DisplayCodeWithLineNumbers.new(
  lines: lines,
  highlight_lines: [lines[2], lines[3]]
).call
# =>
    1
    2  def cat
  > 3    Dir.chdir
  > 4    end
    5  end

This class is responsible for generating initial code blocks that will then later be expanded.

The biggest concern when guessing code blocks, is accidentally grabbing one that contains only an “end”. In this example:

def dog
  begonn # mispelled `begin`
  puts "bark"
  end
end

The following lines would be matched (from bottom to top):

1) end

2) puts "bark"
   end

3) begonn
   puts "bark"
   end

At this point it has no where else to expand, and it will yield this inner code as a block

Class that parses String’s into URI’s.

It contains a Hash set of patterns and Regexp’s that match and validate.

Process::Status encapsulates the information on the status of a running or terminated system process. The built-in variable $? is either nil or a Process::Status object.

fork { exit 99 }   #=> 26557
Process.wait       #=> 26557
$?.class           #=> Process::Status
$?.to_i            #=> 25344
$? >> 8            #=> 99
$?.stopped?        #=> false
$?.exited?         #=> true
$?.exitstatus      #=> 99

Posix systems record information on processes using a 16-bit integer. The lower bits record the process status (stopped, exited, signaled) and the upper bits possibly contain additional information (for example the program’s return code in the case of exited processes). Pre Ruby 1.8, these bits were exposed directly to the Ruby program. Ruby now encapsulates these in a Process::Status object. To maximize compatibility, however, these objects retain a bit-oriented interface. In the descriptions that follow, when we talk about the integer value of stat, we’re referring to this 16 bit value.

A mixin that provides methods for parsing C struct and prototype signatures.

Example

require 'fiddle/import'

include Fiddle::CParser
  #=> Object

parse_ctype('int')
  #=> Fiddle::TYPE_INT

parse_struct_signature(['int i', 'char c'])
  #=> [[Fiddle::TYPE_INT, Fiddle::TYPE_CHAR], ["i", "c"]]

parse_signature('double sum(double, double)')
  #=> ["sum", Fiddle::TYPE_DOUBLE, [Fiddle::TYPE_DOUBLE, Fiddle::TYPE_DOUBLE]]

Mixin for holding meta-information.

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

Provides 3 methods for declaring when something is going away.

+deprecate(name, repl, year, month)+:

Indicate something may be removed on/after a certain date.

+rubygems_deprecate(name, replacement=:none)+:

Indicate something will be removed in the next major RubyGems version,
and (optionally) a replacement for it.

rubygems_deprecate_command:

Indicate a RubyGems command (in +lib/rubygems/commands/*.rb+) will be
removed in the next RubyGems version.

Also provides skip_during for temporarily turning off deprecation warnings. This is intended to be used in the test suite, so deprecation warnings don’t cause test failures if you need to make sure stderr is otherwise empty.

Example usage of deprecate and rubygems_deprecate:

class Legacy
  def self.some_class_method
    # ...
  end

  def some_instance_method
    # ...
  end

  def some_old_method
    # ...
  end

  extend Gem::Deprecate
  deprecate :some_instance_method, "X.z", 2011, 4
  rubygems_deprecate :some_old_method, "Modern#some_new_method"

  class << self
    extend Gem::Deprecate
    deprecate :some_class_method, :none, 2011, 4
  end
end

Example usage of rubygems_deprecate_command:

class Gem::Commands::QueryCommand < Gem::Command
  extend Gem::Deprecate
  rubygems_deprecate_command

  # ...
end

Example usage of skip_during:

class TestSomething < Gem::Testcase
  def test_some_thing_with_deprecations
    Gem::Deprecate.skip_during do
      actual_stdout, actual_stderr = capture_output do
        Gem.something_deprecated
      end
      assert_empty actual_stdout
      assert_equal(expected, actual_stderr)
    end
  end
end
