Performs the uninstall of the gem. This removes the spec, the Gem directory, and the cached .gem file.

Args

v

String

Description

Public setter for the path component v (with validation).

See also URI::Generic.check_path.

Usage

require 'uri'

uri = URI.parse("http://my.example.com/pub/files")
uri.path = "/faq/"
uri.to_s  #=> "http://my.example.com/faq/"

Returns true if URI does not have a scheme (e.g. http:// or https://) specified.

Returns attributes.

Setter for attributes val.

Returns the conversion path of ec.

The result is an array of conversions.

ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP", crlf_newline: true)
p ec.convpath
#=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>],
#    [#<Encoding:UTF-8>, #<Encoding:EUC-JP>],
#    "crlf_newline"]

Each element of the array is a pair of encodings or a string. A pair means an encoding conversion. A string means a decorator.

In the above example, [#<Encoding:ISO-8859-1>,

Construct a new class given a C:

• class klass (CUnion, CStruct, or other that provide an entity_class)

• types (Fiddle::TYPE_INT, Fiddle::TYPE_SIZE_T, etc., see the C types constants)

• corresponding members

Fiddle::Importer#struct and Fiddle::Importer#union wrap this functionality in an easy-to-use manner.

Examples:

require 'fiddle/struct'
require 'fiddle/cparser'

include Fiddle::CParser

types, members = parse_struct_signature(['int i','char c'])

MyStruct = Fiddle::CStructBuilder.create(Fiddle::CUnion, types, members)

MyStruct.malloc(Fiddle::RUBY_FREE) do |obj|
  ...
end

obj = MyStruct.malloc(Fiddle::RUBY_FREE)
begin
  ...
ensure
  obj.call_free
end

obj = MyStruct.malloc
begin
  ...
ensure
  Fiddle.free obj.to_ptr
end

Generate a TextArea element, as a String.

name is the name of the textarea. cols is the number of columns and rows is the number of rows in the display.

Alternatively, the attributes can be specified as a hash.

The body is provided by the passed-in no-argument block

textarea("name")
   # = textarea("NAME" => "name", "COLS" => 70, "ROWS" => 10)

textarea("name", 40, 5)
   # = textarea("NAME" => "name", "COLS" => 40, "ROWS" => 5)

Simple deprecation method that deprecates name by wrapping it up in a dummy method. It warns on each call to the dummy method telling the user of repl (unless repl is :none) and the year/month that it is planned to go away.

Check if gem name version version is installed.

A Zlib::Inflate#inflate wrapper

Creates a State object from opts, which ought to be Hash to create a new State instance configured by opts, something else to create an unconfigured instance. If opts is a State object, it is just returned.

@return [RequirementState] the current state the resolution is

Returns a new Array whose elements are the elements of self at the given Integer indexes.

For each positive index, returns the element at offset index:

a = [:foo, 'bar', 2]
a.values_at(0, 2) # => [:foo, 2]

The given indexes may be in any order, and may repeat:

a = [:foo, 'bar', 2]
a.values_at(2, 0, 1, 0, 2) # => [2, :foo, "bar", :foo, 2]

Assigns nil for an index that is too large:

a = [:foo, 'bar', 2]
a.values_at(0, 3, 1, 3) # => [:foo, nil, "bar", nil]

Returns a new empty Array if no arguments given.

For each negative index, counts backward from the end of the array:

a = [:foo, 'bar', 2]
a.values_at(-1, -3) # => [2, :foo]

Assigns nil for an index that is too small:

a = [:foo, 'bar', 2]
a.values_at(0, -5, 1, -6, 2) # => [:foo, nil, "bar", nil, 2]

The given indexes may have a mixture of signs:

a = [:foo, 'bar', 2]
a.values_at(0, -2, 1, -1) # => [:foo, "bar", "bar", 2]

Deletes an element from self, per the given Integer index.

When index is non-negative, deletes the element at offset index:

a = [:foo, 'bar', 2]
a.delete_at(1) # => "bar"
a # => [:foo, 2]

If index is too large, returns nil.

When index is negative, counts backward from the end of the array:

a = [:foo, 'bar', 2]
a.delete_at(-2) # => "bar"
a # => [:foo, 2]

If index is too small (far from zero), returns nil.
