This module has all methods of FileUtils module, but never changes files/directories, with printing message before acting. This equates to passing the :noop and :verbose flag to methods in FileUtils.

Immutable and read-only representation of a timestamp token info from a Response.

Raised when unexpected case is happen.

Class for representing WebDAV method UNLOCK:

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

• Net::HTTP#unlock: sends UNLOCK request, returns response object.

A FetchError that indicates that the reason for not being able to fetch data was that the host could not be contacted

Gem::Resolver::Molinillo is a generic dependency resolution algorithm.

Error raised when no cdylib artifact was created

Raised if the tar IO is not seekable

IO wrapper that allows writing a limited amount of data

Returns a new Array containing those elements from self that are not duplicates, the first occurrence always being retained.

With no block given, identifies and omits duplicates using method eql? to compare:

a = [0, 0, 1, 1, 2, 2]
a.uniq # => [0, 1, 2]

With a block given, calls the block for each element; identifies (using method eql?) and omits duplicate values, that is, those elements for which the block returns the same value:

a = ['a', 'aa', 'aaa', 'b', 'bb', 'bbb']
a.uniq {|element| element.size } # => ["a", "aa", "aaa"]

With no block, returns a new array containing only unique elements; the array has no two elements e0 and e1 such that e0.eql?(e1):

%w[a b c c b a a b c].uniq       # => ["a", "b", "c"]
[0, 1, 2, 2, 1, 0, 0, 1, 2].uniq # => [0, 1, 2]

With a block, returns a new array containing only for which the block returns a unique value:

a = [0, 1, 2, 3, 4, 5, 5, 4, 3, 2, 1]
a.uniq {|i| i.even? ? i : 0 } # => [0, 2, 4]
a = %w[a b c d e e d c b a a b c d e]
a.uniq {|c| c < 'c' }         # => ["a", "c"]

Like Enumerable#uniq, but chains operation to be lazy-evaluated.

Returns a new Array that is the union of self and all given Arrays other_arrays; duplicates are removed; order is preserved; items are compared using eql?:

[0, 1, 2, 3].union([4, 5], [6, 7]) # => [0, 1, 2, 3, 4, 5, 6, 7]
[0, 1, 1].union([2, 1], [3, 1]) # => [0, 1, 2, 3]
[0, 1, 2, 3].union([3, 2], [1, 0]) # => [0, 1, 2, 3]

Returns a copy of self if no arguments given.

Returns a new regexp that is the union of the given patterns:

r = Regexp.union(%w[cat dog])      # => /cat|dog/
r.match('cat')      # => #<MatchData "cat">
r.match('dog')      # => #<MatchData "dog">
r.match('cog')      # => nil

For each pattern that is a string, Regexp.new(pattern) is used:

Regexp.union('penzance')             # => /penzance/
Regexp.union('a+b*c')                # => /a\+b\*c/
Regexp.union('skiing', 'sledding')   # => /skiing|sledding/
Regexp.union(['skiing', 'sledding']) # => /skiing|sledding/

For each pattern that is a regexp, it is used as is, including its flags:

Regexp.union(/foo/i, /bar/m, /baz/x)
# => /(?i-mx:foo)|(?m-ix:bar)|(?x-mi:baz)/
Regexp.union([/foo/i, /bar/m, /baz/x])
# => /(?i-mx:foo)|(?m-ix:bar)|(?x-mi:baz)/

With no arguments, returns /(?!)/:

Regexp.union # => /(?!)/

If any regexp pattern contains captures, the behavior is unspecified.
