Sets the last Error of the current executing Thread to error

Arguments obj and opts here are the same as arguments obj and opts in JSON.generate.

Default options are:

{
  indent: '  ',   # Two spaces
  space: ' ',     # One space
  array_nl: "\n", # Newline
  object_nl: "\n" # Newline
}

Example:

obj = {foo: [:bar, :baz], bat: {bam: 0, bad: 1}}
json = JSON.pretty_generate(obj)
puts json

Output:

{
  "foo": [
    "bar",
    "baz"
  ],
  "bat": {
    "bam": 0,
    "bad": 1
  }
}

Returns true if this monitor is locked by any thread

Enters exclusive section and executes the block. Leaves the exclusive section automatically when the block exits. See example under MonitorMixin.

Returns the source file origin from the given object.

Sets the list of characters that are word break characters, but should be left in text when it is passed to the completion function. Programs can use this to help determine what kind of completing to do. For instance, Bash sets this variable to “$@” so that it can complete shell variables and hostnames.

See GNU Readline’s rl_special_prefixes variable.

Raises NotImplementedError if the using readline library does not support.

Gets the list of characters that are word break characters, but should be left in text when it is passed to the completion function.

See GNU Readline’s rl_special_prefixes variable.

Raises NotImplementedError if the using readline library does not support.

Adds DidYouMean functionality to an error using a given spell checker

Returns whether or not macro is defined either in the common header files or within any headers you provide.

Any options you pass to opt are passed along to the compiler.

Adds a pre-install hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. If the hook returns false then the install will be aborted.

Adds a hook that will get run before Gem::Specification.reset is run.

Adds a pre-uninstall hook that will be passed an Gem::Uninstaller instance and the spec that will be uninstalled when Gem::Uninstaller#uninstall is called

Calls the given block with each integer value from self up to limit; returns self:

a = []
5.upto(10) {|i| a << i }              # => 5
a                                     # => [5, 6, 7, 8, 9, 10]
a = []
-5.upto(0) {|i| a << i }              # => -5
a                                     # => [-5, -4, -3, -2, -1, 0]
5.upto(4) {|i| fail 'Cannot happen' } # => 5

With no block given, returns an Enumerator.

Calls the given block with each integer value from self down to limit; returns self:

a = []
10.downto(5) {|i| a << i }              # => 10
a                                       # => [10, 9, 8, 7, 6, 5]
a = []
0.downto(-5) {|i| a << i }              # => 0
a                                       # => [0, -1, -2, -3, -4, -5]
4.downto(5) {|i| fail 'Cannot happen' } # => 4

With no block given, returns an Enumerator.

Returns self.

Returns 1.

Returns the numerator.

    1   2       3+4i  <-  numerator
    - + -i  ->  ----
    2   3        6    <-  denominator

c = Complex('1/2+2/3i')  #=> ((1/2)+(2/3)*i)
n = c.numerator          #=> (3+4i)
d = c.denominator        #=> 6
n / d                    #=> ((1/2)+(2/3)*i)
Complex(Rational(n.real, d), Rational(n.imag, d))
                         #=> ((1/2)+(2/3)*i)
