Wakes up the first thread in line waiting for this lock.
Creates an array of handlers for the given libs, can be an instance of Fiddle::Handle, Fiddle::Importer, or will create a new instance of Fiddle::Handle using Fiddle.dlopen
Raises a DLError if the library cannot be loaded.
See Fiddle.dlopen
Sets the type alias for alias_type as orig_type
Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.
Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#readpartial for full details.
Return true if the PRNG has been seeded with enough data, false otherwise.

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)

Is local fetching enabled?
Displays an alert statement. Asks a question if given.
Returns whether this dependency, which has no possible matching specifications, can safely be ignored.
@param [Object] dependency @return [Boolean] whether this dependency can safely be skipped.
Replaces the contents of self with the contents of other_ary, truncating or expanding if necessary.
a = [ "a", "b", "c", "d", "e" ] a.replace([ "x", "y", "z" ]) #=> ["x", "y", "z"] a #=> ["x", "y", "z"]
Returns an array containing the elements in self corresponding to the given selector(s).
The selectors may be either integer indices or ranges.
See also Array#select.
a = %w{ a b c d e f } a.values_at(1, 3, 5) # => ["b", "d", "f"] a.values_at(1, 3, 5, 7) # => ["b", "d", "f", nil] a.values_at(-1, -2, -2, -7) # => ["f", "e", "e", nil] a.values_at(4..6, 3...6) # => ["e", "f", nil, "d", "e", "f"]
When invoked with a block, yield all repeated permutations of length n of the elements of the array, then return the array itself.
The implementation makes no guarantees about the order in which the repeated permutations are yielded.
If no block is given, an Enumerator is returned instead.
Examples:
a = [1, 2] a.repeated_permutation(1).to_a #=> [[1], [2]] a.repeated_permutation(2).to_a #=> [[1,1],[1,2],[2,1],[2,2]] a.repeated_permutation(3).to_a #=> [[1,1,1],[1,1,2],[1,2,1],[1,2,2], # [2,1,1],[2,1,2],[2,2,1],[2,2,2]] a.repeated_permutation(0).to_a #=> [[]] # one permutation of length 0
Passes elements to the block until the block returns nil or false, then stops iterating and returns an array of all prior elements.
If no block is given, an Enumerator is returned instead.
See also Array#drop_while
a = [1, 2, 3, 4, 5, 0] a.take_while { |i| i < 3 } #=> [1, 2]
Numerics are immutable values, which should not be copied.
Any attempt to use this method on a Numeric will raise a TypeError.
Returns a normalized form of str, using Unicode normalizations NFC, NFD, NFKC, or NFKD. The normalization form used is determined by form, which is any of the four values :nfc, :nfd, :nfkc, or :nfkd. The default is :nfc.
If the string is not in a Unicode Encoding, then an Exception is raised. In this context, ‘Unicode Encoding’ means any of UTF-8, UTF-16BE/LE, and UTF-32BE/LE, as well as GB18030, UCS_2BE, and UCS_4BE. Anything else than UTF-8 is implemented by converting to UTF-8, which makes it slower than UTF-8.
Examples
"a\u0300".unicode_normalize #=> 'à' (same as "\u00E0") "a\u0300".unicode_normalize(:nfc) #=> 'à' (same as "\u00E0") "\u00E0".unicode_normalize(:nfd) #=> 'à' (same as "a\u0300") "\xE0".force_encoding('ISO-8859-1').unicode_normalize(:nfd) #=> Encoding::CompatibilityError raised
