Returns the name for the given ‘dependency`. @note This method should be ’pure’, i.e. the return value should depend
only on the `dependency` parameter.
@param [Object] dependency @return [String] the name for the given ‘dependency`.
Constant time memory comparison for fixed length strings, such as results of HMAC
calculations.
Returns true
if the strings are identical, false
if they are of the same length but not identical. If the length is different, ArgumentError
is raised.
Iterates the given block for each element with an index, which starts from offset
. If no block is given, returns a new Enumerator
that includes the index, starting from offset
offset
the starting index to use
Returns a new lazy enumerator with the concatenated results of running block
once for every element in the lazy enumerator.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x
returned by block
is decomposed if either of the following conditions is true:
x
responds to both each and force, which means that x
is a lazy enumerator.
x
is an array or responds to to_ary.
Otherwise, x
is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force #=> [{:a=>1}, {:b=>2}]
Returns a new lazy enumerator with the concatenated results of running block
once for every element in the lazy enumerator.

Returns the size of optional parameters.

Creates a regular expression to match IPv4 addresses
Check that a method is callable via dRuby.
obj
is the object we want to invoke the method on. msg_id
is the method name, as a Symbol
.
If the method is an insecure method (see insecure_method?
) a SecurityError
is thrown. If the method is private or undefined, a NameError
is thrown.
Creates an option parser and fills it in with the help info for the command.
True if the gems in the system satisfy dependency
.
