Results for: "remove_const"

Compiled instruction sequence represented by a RubyVM::InstructionSequence instance on the :script_compiled event.

Note that this method is MRI specific.

Returns a new array with the concatenated results of running block once for every element in enum.

If no block is given, an enumerator is returned instead.

[1, 2, 3, 4].flat_map { |e| [e, -e] } #=> [1, -1, 2, -2, 3, -3, 4, -4]
[[1, 2], [3, 4]].flat_map { |e| e + [100] } #=> [1, 2, 100, 3, 4, 100]

Iterates the given block for each array of consecutive <n> elements. If no block is given, returns an enumerator.

e.g.:

(1..10).each_cons(3) { |a| p a }
# outputs below
[1, 2, 3]
[2, 3, 4]
[3, 4, 5]
[4, 5, 6]
[5, 6, 7]
[6, 7, 8]
[7, 8, 9]
[8, 9, 10]

Adds a post-install hook that will be passed an Gem::Installer instance when Gem::Installer#install is called

Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete

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

Extensions to build when installing the gem, specifically the paths to extconf.rb-style files used to compile extensions.

These files will be run when the gem is installed, causing the C (or whatever) code to be compiled on the user’s machine.

Usage:

spec.extensions << 'ext/rmagic/extconf.rb'

See Gem::Ext::Builder for information about writing extensions for gems.

Sets extensions to extensions, ensuring it is an array. Don’t use this, push onto the array instead.

Returns extensions.

Setter for extensions val.

Called when an instruction is encountered. EG: <?xsl sheet=‘foo’?> @p name the instruction name; in the example, “xsl” @p instruction the rest of the instruction. In the example, “sheet=‘foo’”

Appends the elements of other_arys to self.

[ "a", "b" ].concat( ["c", "d"])   #=> [ "a", "b", "c", "d" ]
[ "a" ].concat( ["b"], ["c", "d"]) #=> [ "a", "b", "c", "d" ]
[ "a" ].concat #=> [ "a" ]

a = [ 1, 2, 3 ]
a.concat( [ 4, 5 ])
a                                 #=> [ 1, 2, 3, 4, 5 ]

a = [ 1, 2 ]
a.concat(a, a)                    #=> [1, 2, 1, 2, 1, 2]

When invoked with a block, yields all combinations of length n of elements from the array and then returns the array itself.

The implementation makes no guarantees about the order in which the combinations are yielded.

If no block is given, an Enumerator is returned instead.

Examples:

a = [1, 2, 3, 4]
a.combination(1).to_a  #=> [[1],[2],[3],[4]]
a.combination(2).to_a  #=> [[1,2],[1,3],[1,4],[2,3],[2,4],[3,4]]
a.combination(3).to_a  #=> [[1,2,3],[1,2,4],[1,3,4],[2,3,4]]
a.combination(4).to_a  #=> [[1,2,3,4]]
a.combination(0).to_a  #=> [[]] # one combination of length 0
a.combination(5).to_a  #=> []   # no combinations of length 5

Returns the complex conjugate.

Complex(1, 2).conjugate  #=> (1-2i)

Returns the complex conjugate.

Complex(1, 2).conjugate  #=> (1-2i)

Returns self.

Returns self.

Convert self to to_enc. to_enc and from_enc are given as constants of Kconv or Encoding objects.

Concatenates the given object(s) to str. If an object is an Integer, it is considered a codepoint and converted to a character before concatenation.

concat can take multiple arguments, and all the arguments are concatenated in order.

a = "hello "
a.concat("world", 33)      #=> "hello world!"
a                          #=> "hello world!"

b = "sn"
b.concat("_", b, "_", b)   #=> "sn_sn_sn"

See also String#<<, which takes a single argument.
