Makes a list of existing constants deprecated. Attempt to refer to them will produce a warning.

module HTTP
  NotFound = Exception.new
  NOT_FOUND = NotFound # previous version of the library used this name

  deprecate_constant :NOT_FOUND
end

HTTP::NOT_FOUND
# warning: constant HTTP::NOT_FOUND is deprecated

returns an integer in (-infty, 0] a number closer to 0 means the dependency is less constraining

dependencies w/ 0 or 1 possibilities (ignoring version requirements) are given very negative values, so they always sort first, before dependencies that are unconstrained

in ConstantReadNode in String

Example:

Foo
^^^

Foo ^^^

A shareable constant.

Indicated, based on the requested domain, if remote gems should be considered.

Returns true if the contents of streams a and b are identical, false otherwise.

Arguments a and b should be interpretable as a path.

Returns true if the contents of streams a and b are identical, false otherwise.

Arguments a and b should be interpretable as a path.

Foo ^^^

A shareable constant.

Foo
^^^

A shareable constant.

Returns true if the given argument is within self, false otherwise.

With non-range argument object, evaluates with <= and <.

For range self with included end value (exclude_end? == false), evaluates thus:

self.begin <= object <= self.end

Examples:

r = (1..4)
r.cover?(1)     # => true
r.cover?(4)     # => true
r.cover?(0)     # => false
r.cover?(5)     # => false
r.cover?('foo') # => false

r = ('a'..'d')
r.cover?('a')     # => true
r.cover?('d')     # => true
r.cover?(' ')     # => false
r.cover?('e')     # => false
r.cover?(0)       # => false

For range r with excluded end value (exclude_end? == true), evaluates thus:

r.begin <= object < r.end

Examples:

r = (1...4)
r.cover?(1)     # => true
r.cover?(3)     # => true
r.cover?(0)     # => false
r.cover?(4)     # => false
r.cover?('foo') # => false

r = ('a'...'d')
r.cover?('a')     # => true
r.cover?('c')     # => true
r.cover?(' ')     # => false
r.cover?('d')     # => false
r.cover?(0)       # => false

With range argument range, compares the first and last elements of self and range:

r = (1..4)
r.cover?(1..4)     # => true
r.cover?(0..4)     # => false
r.cover?(1..5)     # => false
r.cover?('a'..'d') # => false

r = (1...4)
r.cover?(1..3)     # => true
r.cover?(1..4)     # => false

If begin and end are numeric, cover? behaves like include?

(1..3).cover?(1.5) # => true
(1..3).include?(1.5) # => true

But when not numeric, the two methods may differ:

('a'..'d').cover?('cc')   # => true
('a'..'d').include?('cc') # => false

Returns false if either:

Beginless ranges cover all values of the same type before the end, excluding the end for exclusive ranges. Beginless ranges cover ranges that end before the end of the beginless range, or at the end of the beginless range for inclusive ranges.

(..2).cover?(1)     # => true
(..2).cover?(2)     # => true
(..2).cover?(3)     # => false
(...2).cover?(2)    # => false
(..2).cover?("2")   # => false
(..2).cover?(..2)   # => true
(..2).cover?(...2)  # => true
(..2).cover?(.."2") # => false
(...2).cover?(..2)  # => false

Endless ranges cover all values of the same type after the beginning. Endless exclusive ranges do not cover endless inclusive ranges.

(2..).cover?(1)     # => false
(2..).cover?(3)     # => true
(2...).cover?(3)    # => true
(2..).cover?(2)     # => true
(2..).cover?("2")   # => false
(2..).cover?(2..)   # => true
(2..).cover?(2...)  # => true
(2..).cover?("2"..) # => false
(2...).cover?(2..)  # => false
(2...).cover?(3...) # => true
(2...).cover?(3..)  # => false
(3..).cover?(2..)   # => false

Ranges that are both beginless and endless cover all values and ranges, and return true for all arguments, with the exception that beginless and endless exclusive ranges do not cover endless inclusive ranges.

(nil...).cover?(Object.new) # => true
(nil...).cover?(nil...)     # => true
(nil..).cover?(nil...)      # => true
(nil...).cover?(nil..)      # => false
(nil...).cover?(1..)        # => false

Detaches the current process from its controlling terminal and runs it in the background as system daemon; returns zero.

By default:

If optional argument nochdir is true, does not change the current working directory.

If optional argument noclose is true, does not redirect $stdin, $stdout, or $stderr.

Returns a data represents the current console mode.

You must require ‘io/console’ to use this method.
